Electrum Bitcoin Wallets Left Exposed to Hacks for Two Years

Groestlcoin 6th Anniversary Release


Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything.
The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years.
In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.

UPDATED - Groestlcoin Core 2.18.2

This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables.
NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.

How to Upgrade?

If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer.
If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), run the dmg and drag Groestlcoin Core to Applications.

ALL NEW - Groestlcoin Moonshine iOS/Android Wallet

Built with React Native, Moonshine utilizes Electrum-GRS's JSON-RPC methods to interact with the Groestlcoin network.
GRS Moonshine's intended use is as a hot wallet. Meaning, your keys are only as safe as the device you install this wallet on. As with any hot wallet, please ensure that you keep only a small, responsible amount of Groestlcoin on it at any given time.





ALL NEW! – HODL GRS Android Wallet

HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled.
HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user.
Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.

ALL NEW! – GroestlcoinSeed Savior

Groestlcoin Seed Savior is a tool for recovering BIP39 seed phrases.
This tool is meant to help users with recovering a slightly incorrect Groestlcoin mnemonic phrase (AKA backup or seed). You can enter an existing BIP39 mnemonic and get derived addresses in various formats.
To find out if one of the suggested addresses is the right one, you can click on the suggested address to check the address' transaction history on a block explorer.


Live Version (Not Recommended)





ALL NEW! – Vanity Search Vanity Address Generator

NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator.
VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline.
If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address.
VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase.
VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).






ALL NEW! – Groestlcoin EasyVanity 2020

Groestlcoin EasyVanity 2020 is a windows app built from the ground-up and makes it easier than ever before to create your very own bespoke bech32 address(es) when whilst not connected to the internet.
If you're tired of the random, cryptic bech32 addresses generated by regular Groestlcoin clients, then Groestlcoin EasyVanity2020 is the right choice for you to create a more personalised bech32 address. This 2020 version uses the new VanitySearch to generate not only legacy addresses (F prefix) but also Bech32 addresses (grs1 prefix).




Remastered! – Groestlcoin WPF Desktop Wallet (v2.19.0.18)

Groestlcoin WPF is an alternative full node client with optional lightweight 'thin-client' mode based on WPF. Windows Presentation Foundation (WPF) is one of Microsoft's latest approaches to a GUI framework, used with the .NET framework. Its main advantages over the original Groestlcoin client include support for exporting blockchain.dat and including a lite wallet mode.
This wallet was previously deprecated but has been brought back to life with modern standards.


Remastered Improvements



ALL NEW! – BIP39 Key Tool

Groestlcoin BIP39 Key Tool is a GUI interface for generating Groestlcoin public and private keys. It is a standalone tool which can be used offline.



Linux :
 pip3 install -r requirements.txt python3 bip39\_gui.py 


ALL NEW! – Electrum Personal Server

Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node.
It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node.
Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine.
Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in.
Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet.
Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.



Linux / OSX (Instructions)


UPDATED – Android Wallet 7.38.1 - Main Net + Test Net

The app allows you to send and receive Groestlcoin on your device using QR codes and URI links.
When using this app, please back up your wallet and email them to yourself! This will save your wallet in a password protected file. Then your coins can be retrieved even if you lose your phone.

UPDATED – Groestlcoin Sentinel 3.5.06 (Android)

Groestlcoin Sentinel is a great solution for anyone who wants the convenience and utility of a hot wallet for receiving payments directly into their cold storage (or hardware wallets).
Sentinel accepts XPUB's, YPUB'S, ZPUB's and individual Groestlcoin address. Once added you will be able to view balances, view transactions, and (in the case of XPUB's, YPUB's and ZPUB's) deterministically generate addresses for that wallet.
Groestlcoin Sentinel is a fork of Groestlcoin Samourai Wallet with all spending and transaction building code removed.

Chat_Report.25>2 - XL

[22:12] it's not like I'm going to be offended that someone feels that way [22:12] but it's not healthy to be a dick about it, and that's kind of the only way that I can think to be able to deal with it [22:12] I guess, that's not a bad way to think about it [22:12] if you're having trouble dealing with it [22:12] I guess I just have to accept that I am not an expert on that [22:12] but I do have the most basic understanding of the concept [22:12] and I have always known what a "dissociative" is [22:12] and that they are in fact a distinct psychological state [22:13] I didn't have to google to find out [22:13] and in fact I have been working on a book on dissociative phenomena for a number of years [22:13] you mean you were trying to find out what they were? [22:13] i just finished [22:14] i got the manuscript finished and submitted a copy [22:14] well, the "book" is still on your todo list [22:14] i'm very anxious to publish [22:15] what about the research? are you doing any research on it? [22:15] and yes [22:16] some, but the bulk of my effort is in trying to make sense of it [22:16] what are you doing to help us understand it? [22:16] and i have a blogpost of my own that goes into the background of the phenomenon [22:16] it would be great if you could tell us a little about it [22:16] it sounds as if the phenomenon has something to do with people who have had a life-altering experience [22:17] and that the thing they have experienced is so powerful that it is capable of completely altering a person's personality [22:17] (well, that and the fact that a person who had such an experience could have access to the internet) [22:17] i'm sorry, but why not just tell us about it in full detail, instead of asking me a bunch of question and letting me decide what to ask [22:18] it would be very convenient to you [22:18] if you hadnt decided not to talk about it until after i had. [22:18] if you want to know more, it's quite common for people with this kind of problem to share their stories. [22:18] (i'm not sure if its normal, but i can assure you its not something i wouldn't ever do to any of you) [22:19] so i don't know what you're implying by saying you're uncomfortable with talking about it? [22:19] i'm just saying that i'm not going to force you to talk about it just because you told me it was hard to talk about [22:19] ok. [22:20] so this is it: you must come here with me now [22:20] ok [22:20] and I'll go to the other rooms and meet everyone. [22:20] I want to make this a place for everyone [22:21] ok [22:21] i'll talk to you when i get there [22:21] OK, I need a little more detail [22:22] What's the plan for getting it into the house? [22:22] well i'll let you know when i get there [22:22] Ok, thanks [22:22] i'll be back around 12:30 and ill be there [22:23] I've sent you a PM for the key and I'll be waiting for you to talk to her [22:23] lol [22:23] *key [22:23] ouch [22:24] But that's just me [22:24] You can't just go and do it like that, y'know? [22:24] lol [22:25] but if it's just a matter of asking me nicely, i don't mind [22:25] just send it to me and i'll do it [22:25] if that's what you want [22:25] I've never asked you to do anything but that, and I know you haven't, but, that's my opinion [22:26] I mean, if it helps you out a little bit, maybe I could just... [22:26] Vorpas, that's okay. I mean, I think you're pretty amazing, I do, I do. I just don't know what you want to do with your life. I think I'd like to try and get the people that are in the game to understand the power and the importance of the community. I mean, when you're playing against, when you see a really bad player, you can tell that that player is having fun, that they are having fun playing the game, because they are making a lot of money, and then you can just understand that it would be fun to play, and there would be a lot of money to be made by just playing the game. And I think the players that are playing it, maybe they don't know what's happening, and maybe they have the wrong idea about it. But it's okay, I'm not going to judge them, it's their own opinion and they're free to believe whatever they want to believe. [22:27] But, I'm just gonna leave that part up to you. [22:27] Cool. [22:27] So I'm just gonna be, like, really happy for you, 'cause I know you've been putting a lot of work into this. [22:28] You are doing it so well! [22:28] And I really appreciate that, like, for the last few months, it's been a struggle to stay motivated enough to do this. [22:28] I am a bit concerned about how long this will take. [22:28] I am just going to say this, if I'm going to continue doing this, I want you guys to stay around. [22:29] Well, I would love to keep helping, but I'm not sure what my plans are at the moment. [22:29] If you were to make a donation, that would be fantastic [22:29] You know, the donations are very helpful. I just thought that it might be good to keep track of who donated what. [22:29] Vorpas_Jabwak, I can try to get someone to check if this was indeed you that made the donation? [22:29] Oh, yeah. [22:29] Thanks! [22:29] You've probably never received one before, but if you were, that would be awesome. [22:30] Just wanted to let you know the new version of Mumble is being released and working on the beta channel. [22:31] If you do have the software I'd love to hear some feedback. I have a lot of questions for it. [22:32] I have a lot of questions for it too, but it's a bit complicated so I might not get a chance to do that anytime soon. I'll make sure to get on that when it is ready. [22:33] I'm glad you like it, I know I really do. I love having an easier to use, but powerful, voice chat. [22:34] I'd really like to make some more changes to the system, and try it out as a whole. But right now it's pretty darned good. [22:35] Thanks Jak. :) [22:35] I'll try my best to keep them updated. [22:35] Ok, I'll let you know when I get to them, Jak [22:35] Sorry if I didn't keep up with you guys. [22:36] Haha, sorry. [22:36] I'll see you around, Jak [22:36] *takes off* [22:36] Sup everyone? [22:36] I'm out [22:36] *in [22:37] sup [22:37] Hey! [22:37] So are you guys all there yet? [22:37] :P [22:38] * Turoth sets mode: +b KhaosReigns [22:38] Oh! I thought you all quit on me [22:38] * Turoth sets mode: +b KhaosReigns+ [22:38] So uh, what's my problem? [22:38] I was hoping you'd tell me to stop [22:38] I was so upset [22:38] I'm sorry [22:38] I should have been better [22:39] I didn't mean to startle you [22:39] You've just always made me feel like I could take care of myself [22:39] I guess I didn't realize that it takes a lot of people to keep the lights on [22:40] I'm sorry, I've never been this shy around people [22:40] It's been such a long time [22:41] This whole situation is just a shock [22:41] I'm starting to feel really nervous [22:41] I have to go home now [22:42] Ok [22:42] I'll see you later [22:42] Ohh, bye [22:42] Take care [22:42] Yeah, it's a long way home [22:42] Have a nice night [22:42] Thanks for everything. I had fun. [22:42] night [22:42] I hope you have a good night. [22:42] Have a nice night. [22:42] Thanks. [22:42] Have a good night. [22:42] Good night [22:42] How is everyone? [22:42] I'm fine. [22:42] Tired, but fine. [22:42] Yeah. [22:43] i dont know what happened [22:43] Don't know yet, so I'm trying to get the details. [22:43] I went out to get food [22:43] got a pizza, was eating it when I was interrupted by my girlfriend [22:43] and she was saying she wanted to see me [22:43] i don't even know where i am right now [22:44] so she called me at work this morning and said 'well, i'm sorry i couldn't make it for you today', and i had to tell her 'okay' [22:45] i cant find her or the phone number or anything [22:45] i was just in the car, and she was in the kitchen [22:45] it must of been a while [22:45] i think she was off last night [22:46] that's funny that you would call me like that [22:46] then you should know that she has been off for a while [22:46] she said she was sick, and i think she said she was going to stay home and rest and it wasn't till today that i found out the truth [22:46] yeah it's a real bummer that it was a false alarm [22:46] like i said she could have possibly been sick but wasnt being honest about it [22:46] it is a big bummer that we wasted so much time on it, but it doesn't change that we found her body [22:46] yeah we know how the night went, we just dont know if she was really asleep when the phone rang [22:46] i just wish she would have just told us the truth instead of getting her feelings hurt [22:46] the real question is: why is it a phone? [22:46] that's all i got [22:46] so that's it [22:46] yeah and she's got to go find out if she's pregnant [22:46] and i guess there's no point in trying to hide the pregnancy [22:46] she said it was just a few days ago [22:46] wait what [22:46] maybe her parents are going to find it [22:46] ok [22:46] maybe if her parents find out she's pregnant [22:46] they'll just throw you out [22:46] they will [22:47] why do you think she was crying? [22:47] well, I mean, I know it's weird but [22:47] no, you're right [22:47] I mean, it was pretty strange [22:47] she just seemed, well [22:47] I don't think she could have known the guy or not [22:47] there's been plenty of reports of people getting "paedo" on the site [22:47] so it could have just been that her brain just caught on [22:47] like that one guy who was arrested last year for having a lot of chatroom porn [22:47] which is like a whole different thing [22:48] and it just happened to be in that section that she kept checking [22:48] yeah [22:48] like it's not like she has this huge fucking file of porn on her computer [22:48] so if it happens to be in one place, it's not like she's a big fucking voyeur [22:49] but still, she was watching the entire thing [22:49] yes, and that is probably why the guy stopped her [22:49] I can see your point of view [22:50] and it was also in that section that she just kept checking [22:50] yes, and I can say that she just seemed so interested in the guy that she wouldn't mind if he was watching [22:50] and that's not exactly the case with me either [22:50] but, if she's only interested in other men, then she's obviously gay [22:51] which is just something to remember [22:51] and she's so smart, but I can't see her getting on with me [22:51] she has a crush on me, but I don't even know where to start [22:52] I was at a party in NY, and someone I knew was talking to her, and they had been flirting. I didn't get a chance to respond, but I am a nice guy. She said she didn't want to talk about it any more. I am a nice guy, and I know that flirting is bad, but I also know that I like her and I think that there's a chance that it could go somewhere. I want to have a relationship with her, I don't really know where to start [22:52] you'd have to ask her yourself [22:52] but it seems like you don't have to [22:52] but if that's your only point she can't really say something else... [22:52] i think if you were to say you didn't want to have sex with her, you would lose her... [22:52] i'm not even really interested in that right now [22:53] it just seems like she wants to have sex with you [22:53] and is hoping that you'll say yes [22:53] i guess so... [22:53] but she doesn't seem to be trying to win your votes [22:53] maybe she's just trying to piss you off [22:54] and you don't have the time to argue with her [22:54] the internet is a bitch. [22:54] but i know she's just trying to be funny [22:54] and to make a point [22:54] so why can't i? [22:54] yeah [22:54] what do you mean? [22:54] jalockk: i've never seen a single one of these people [22:54] but i see them every day [22:54] and they say the same shit [22:54] we don't like the idea of them being taken out because they are not the ones we really are against [22:54] well i don't think we need to be very big to do that [22:54] but they are a part of it [22:55] the people that dont like us [22:55] the people that are behind all this [22:55] or just the people [22:55] not the people [22:55] it's the people that don't have an opinion [22:56] we should never let our ignorance define us [22:56] well we're doing it now [22:56] and it's not even funny [22:56] it's just sad [22:56] no it's a serious problem [22:56] it's not funny [22:56] and the truth is sadder [22:56] i don't understand why he hates himself so much [22:56] is it because of the death [22:56] or the lies he told [22:56] that's what im trying to figure out too [22:57] not that there is an obvious answer to why he does what he does [22:57] i think he is a pretty shitty person [22:57] the lies hurt more [22:57] i really really wish i could understand [22:58] that's why i'm here to explain the way out [22:58] if i explain it to you in words [22:58] well i don't know you [22:58] i have to explain it to you in a way that makes sense to you [22:58] in english [22:58] and that's how [22:58] this whole thing starts with a picture of a woman [22:58] holding up a phone with the words "HELLO" on the screen [22:58] it's a picture of me [22:58] It's a pic of me in a hat [22:58] and i'm in the hat [22:58] which isnt me [22:58] i'm the one with the hat [22:59] i wear a hat to hide my face [22:59] and when i say this i don't really say "i'm the hat" [22:59] i say "i'm the hat" [22:59] oh okay [22:59] ok let me get this straight [22:59] if we're talking about the "why" [22:59] what the actual, fucking, fuck [22:59] why did she do it [22:59] the "when" part I'm not clear about [22:59] i'd assume that's the part we're discussing [22:59] ok i'm getting out of this [22:59] but yeah the "what" [22:59] yeah [22:59] and it seems like the "how" [22:59] isnt really a big deal [22:59] i think it is [22:59] the fact that we all agree on what it is [22:59] and are people who say its a big deal really saying it on the op? or is it on the op, and people who say its a big deal are just assholes? [22:59] we're pretty fucking certain it's not a big deal [22:59] if you're not convinced [22:59] please say so in the thread [22:59] i'd love to hear your arguments [22:59] the op is just a big deal, it is a huge deal, we've done the math, and there is no downside [22:59] we've actually spent the last 2 days talking about it [22:59] it doesn't really have any consequences on us, as we won't do anything stupid [22:59] we'd be better off not having it in the first place [22:59] it doesn't really matter [22:59] I know I'm a bit biased but... this whole thing feels like it's been set up to be solved by trolls [22:59] not to mention that we can already see a lot of the stuff they are talking about, they just don't want to talk about it [22:59] it's not like they would go back to it and say "we got this, so why don't you shut up!" [22:59] It's frustrating to see them try and keep this open... but it's a shame to see what happens when they fail. [22:59] I love how it seems like the more they try to keep it secret, the more they are forced to keep it open [22:59] :O [23:00] well we don't know yet what they have planned for the next phase but there's a lot of work to be done [23:00] no one knows what we'll be doing now, so if we do everything right, we could actually end up with some more power [23:00] i'm not saying we'll get that, we'll have to wait and see [23:00] maybe i'm just a bit optimistic [23:00] or maybe i'm just stupid? [23:01] i dunno i don't care anymore [23:01] just wait it out [23:01] no time to waste [23:01] let them make it as easy as possible [23:01] and keep an eye on what they say next [23:01] well that could mean some kind of delay [23:01] like they are going to push it out [23:01] well, that's their prerogative [23:01] what they said a month ago is what they're saying now? [23:01] Ok, I'm gonna leave this here: http://en.wikipedia.org/wiki/Woot\_com [23:01] but I can't find the link right now. :( [23:01] it's been posted to the website of the US government [23:01] so you know it's legit [23:02] oh. Ok. [23:02] so it's legit [23:02] ok. [23:02] So, we're not really at the point of doing the whole, "we have a solution" thing, so much as a "we have a general idea" thing. [23:03] i think that's what we're going for [23:03] the problem, in my experience, is that it's hard for people to really figure out what you're talking about. I would assume that with a lot of the work that's going on there are some people who are really good at solving it. I'm not. [23:04] i mean, it is sort of in the realm of "people" [23:04] that we've been able to make progress on this, so i am assuming you have done a lot of that work? [23:04] i would have to ask someone else how they are doing it [23:05] in terms of the algorithms they use [23:05] or other tools [23:06] http://bitinfocharts.com/blocksize-and-bitcoin-future-chart/ [23:06] but i don't know how you guys did it in a way that is also practical [23:06] no problem. it's been done. [23:06] just don't expect anyone to do it for you [23:07] i'll have to ask you that one [23:07] if you have a better idea please post it here and we'll discuss it [23:07] but if we don't have a better idea then we don't know what you're talking about [23:08] it's not our fault they are doing it [23:08] they do it to us [23:08] we don't have any other solution [23:08] but they have access to your wallet [23:09] you are paying for access to it [23:09] so they are getting access [23:09] you are paying to keep their access to your wallet [23:10] I am paying to keep your access to your wallet [23:10] they are making you do it [23:10] i am paying them to keep access to my wallet [23:10] that is what i have been told to do [23:10] what i was told to do [23:10] i am also paying them for this access [23:10] I am not paying to keep access to my wallet for them [23:11] I am paying them for this access [23:11] to mine in their account for them [23:12] well, that was fun [23:12] oh, that's too bad [23:12] it's all for you [23:12] you are mining it for them [23:12] so much for that [23:12] but then you are the victim of a scam, not me [23:13] oh, ok [23:13] it's a good thing you are aware now, because that is a great way to get scammed [23:13] so what's up? [23:14] ok [23:14] we've been looking for you for a while now and we can't find you. [23:14] ok. so what's up? [23:15] the last time you were on IRC we started doing our own investigation and you didn't know where you were or how long you'd been gone [23:15] so we thought that since you weren't there anymore that it had to be a scam [23:15] which it is [23:15] http://www.youtube.com/watch?v=h0bzvq8Fx7Y [23:15] yeah. but it doesnt tell you that [23:15] you gotta ask [23:15] you got that right [23:16] alright. let me see if I can find something similar [23:16] https://www.youtube.com/watch?v=nUZpwWg1g\_s [23:16] http://www.youtube.com/watch?v=pFwX4jJYqhI [23:16] i have a different one [23:16] http://www.youtube.com/watch?v=h\_h2rK4V7ZM [23:16] it is shorter [23:16] it has less information [23:17] http://www.youtube.com/watch?v=DYpq6H2jkZg [23:17] http://www.youtube.com/watch?v=DYpq6H2jkZg [23:17] http://www.youtube.com/watch?v=DYpq6H2jkZg [23:17] http://www.youtube.com/watch?v=DYpq6H2jkZg [23:17] http://www.youtube.com/watch?v=DYpq6H2jkZg [23:17] http ://www.youtube.com [23:17] http://www.youtube.com [23:17] http://www.youtube.com [23:17] ok I have been listening [23:18] let me hear your response to the question "why are you talking on the radio?" [23:18] "The answer to that is because I was just trying to communicate with the community" [23:18] why do you think it's a good idea to try to communicate with the community? [23:18] you don't need to ask, we're going to have a drink [23:18] let me get you something to drink [23:18] i will be back later [23:18] in like 2 mins [23:18] can you hear me? [23:18] yes, I can hear you [23:18] are you a bot? [23:18] no, i am human [23:19] oh [23:19] good to know [23:19] you're just very very drunk, i guess [23:19] just go to sleep [23:20] you just have to go to sleep [23:20] and it'll be over by the morning [23:20] i'll wait [23:21] but it was only a few hours ago [23:21] and i said it wouldn't be [23:21] so i'm guessing you can't help it [23:21] so is it over? [23:21] not sure if you can help it or not, but if you have any questions or suggestions, do send them to me [23:22] but yeah, there is no immediate threat at all [23:22] but i dont know what to do at the moment, maybe i should move everything to another server [23:22] but i have the code and the rpc server [23:22] you can do that? [23:22] yeah, just let me know what you want [23:22] okay, how do i run rpc from my localhost? [23:22] just open up a terminal and run "rpcuser -i" [23:22] okay [23:22] let's go back to maint [23:22] I'm going to add another option to run the wallet (wallet.conf) as a non root user [23:22] I'm going to add rpcuser as an option, and rpcpassword as a second option [23:22] and then run as root [23:23] okay, so what do i want the output of this command to be [23:23] the output should be something like "1" [23:23] what should i put in the command? [23:23] for now, i'll just type it out [23:23] rpcuser=myuser rpcpassword=mypassword [23:23] run_in_remote.sh --port=21 --listen= [23:23] you should be able to type that in [23:23] and it should go through ok. you should see something like this: [23:23] [00:11] [23:21] [00:20] [23:23] what do i do to make the next post more visible? [23:23] can someone send a screenshot of the reddit post to me? [23:23] @emmaw [23:23] i can give you my address in case you want to send something there [23:23] you're welcome [23:23] well im going to have to ask the mod team that question now [23:23] thanks for the offer, we'll think about it [23:23] :) [23:23] i'll give you the link soon, also [23:23] but please don't PM me about that :) [23:24] sure [23:24] i'll leave it with you [23:24] but i'll check it again [23:24] later [23:25] so is this the one with the red pill? [23:25] or redpilled? [23:25] redpilled [23:25] redpilled [23:25] ok [23:25] thanks [23:25] I got the link [23:25] yeah [23:25] this is a very big deal [23:25] I'm in a hurry, so I can't see the link, but what you're doing is a lot more powerful than most of what I've ever heard before [23:26] http://www.youtube.com/watch?v=Hjf7hKQ6uQg [23:26] that's a pretty long video [23:26] yeah [23:26] there's lots of cool stuff in there, too [23:26] it has a nice flow to it, too [23:26] so, you have to remember: don't focus on the structure, focus on the content [23:27] i see [23:27] not sure if thats just me though [23:27] its a good thing to have [23:27] not sure why the devs don't do it, but there are some good reasons [23:27] yeah i got your point [23:27] im happy to make it easy for you [23:27] and for other devs to do it as well [23:27] (at least a few of the devs are here to see this) [23:27] we could even get a group of devs to go talk to the press and try to have the topic in a few of the big gaming sites [23:28] this could be a great way to get the game out and to everyone else [23:28] and then we can move onto the next thing [23:28] if this is successful I think we can even get some of the smaller ones to try it [23:28] also if any of the other big ones do it this will get them in on the process

Could not connect to Bitcoin Core using JSON-RPC error message when launching Eclair

Hi! I am new to the Lightning Network and I am seeking to install a Lighting Network full node on my PC.

I already have Bitcoin Core installed and my full bitcoin node working (version 0.17.1).

I went through some steps to install the LN full node on a video on YouTube, following instructions from a Medium post: "How to run a Lightning Network node on Windows" (https://medium.com/coinmonks/guide-setup-a-lightning-network-node-on-windows-8475206807f).

I installed Eclair (v0.2-beta9) from their Github page.

But when I try to launch Eclair (with my Bitcoin Core node up and running), an error message pops us, saying:
Could not connect to Bitcoin Core using JSON-RPC.
Make sure that Bitcoin Core is up and running and RPC parameters are correct.

Here is what I have in my Bitcoin Core .conf file:


And in my eclair.conf file:


By the way, I went through an old thread on the same topic (https://www.reddit.com/lightningnetwork/comments/7rlk1e/could_not_connect_to_bitcoind_using_jsonrpc_any/), but the solutions proposed did not work for me.

Your help would be greatly appreciated :-) Thanks!

[DEVELOPMENT] Bitcoind IPV4 testnet port (18332) is failing to bind

[SOLVED] Thanks for everyone that have helped!

Hello everyone, this is a development problem that I'm currently having. Since the BTC Development sub is kind of inactive and I couldn't find any rule contraty to posting about BTC Development, I'll try my luck in here as I'm hopeless already. I've posted on BTC Stack Exchange but no answers also. Please, don't get me wrong, I'm trying to solve this problem for many days now, I've looked up everywhere for this.
I'm new to Bitcoin development and I'm currently having difficulties trying to make RPC calls from a Docker Container to a Bitcoin-Core daemon running in a SSH server. I suppose that the problem may be with Firewall or closed ports, but I also do not know much about Network settings.
I'm using nbobtc/bitcoind-php package to make the RPC calls with HTTP requests, and it is running in a Docker container. I'm sure the container is functional and is not the problem.
So here's what happening: when I run bitcoind in root user (but normal also won't work) in my SSH server, the IPV4 testnet port seems to be not opened. This message goes up when I run bitcoind:
Binding RPC on address port 18332 failed.
Here's what my bitcoin.conf looks like (I want to use testnet in here). I'm using Bitcoin-Core "subversion": "Satoshi:0.17.1".
server=1 debug=net txindex=1 testnet=1 rpcuser=userb rpcpassword=test test.rpcport=18332 # I've already tried allowing the IP these 3 ways: # rpcallowip=192.168.xx.xx # My machine's IP # rpcallowip=172.19.x.x/xx # Docker's NBOBTC container IP # rpcallowip= # Allowing all IP datadir=/home/bitcoin-dev/.bitcoin debuglogfile=/home/bitcoin-dev/.bitcoin/debug.log 
Here's what appears in debug.log right after I run Bitcoind:

After all that appears above, there are just "UpdateTip", "Requesting block", "received block" and "getdata" messages. (so the P2P port, 18333, works).

And here is when I netstat:

sudo netstat -nap|grep bitcoin|grep LISTEN
tcp 0 0* LISTEN 31185/bitcoind tcp6 0 0 :::18332 :::* LISTEN 31185/bitcoind tcp6 0 0 :::18333 :::* LISTEN 31185/bitcoind 
Thank you in advance!

PS: A few days ago I could make it work when running bitcoind with root user, but now even that won't solve the problem.

function return value undefined with node js

Hi guys,

I'm new in the javascript world and now I have a problem with a simple function that returns value because this value is not defined, but if I print the value in the function with console.log, the result is correct

My class with the function
const {createBitcoinRpc} = require('@carnesen/bitcoin-rpc'); module.exports = WrapperRPC; var bitcoinRpc; function WrapperRPC(rpcuser, rpcpassword) { this.rpcuser = rpcuser; this.rpcpassword = rpcpassword; this.rpcHref = 'http://' + this.rpcuser + ':' + this.rpcpassword + '@'; bitcoinRpc = createBitcoinRpc(this.rpcHref); //TODO settin this variable } WrapperRPC.prototype.getDimensionBlockchain = function(){ console.debug("the url is:" + this.rpcHref); bitcoinRpc("getblockcount").then(result => { console.debug("The result command is: " + result); this.result = result; return this.result; }).catch(exception => { console.error('exception generated: ' + exception) }) }; WrapperRPC.prototype.getHashBlock = function (heightBlock) { console.debug("Run command getblockhash"); bitcoinRpc('getblockhash', { height: heightBlock }).then(result => { console.debug("The result command is: " + result); this.result = result; return this.result; }).catch(exception => { console.error('exception generated: ' + exception) }); } 
My main
const express = require('express'); const app = express(); const port = 3000; const WrapperRPC = require('./model/WrapperRPCBitcoin'); var path = require('path'); app.get('/', function(req, res) { res.sendFile(path.join(__dirname + '/index.html')); console.log("try to run rpc"); let rpc = new WrapperRPC('vincent', 'vincent'); let numbarBlock = rpc.getDimensionBlockchain(); console.debug("height blockchain: " + numbarBlock); for(i = 0; i < numbarBlock; i++){ var hashBlock = rpc.getHashBlock(i); console.debug('Hash block ' + i + ' is: ' + hashBlock); } }); // Console will print the message app.listen(port, () => console.log(`Example app listening on port ${port} at the link http://localhost:${port}/`)); 
My log
Example app listening on port 3000 at the link http://localhost:3000/ try to run rpc the url is:http://vincent:[email protected]:8332 height blockchain: undefined The result command is: 586965 
The log is correct The result command is: 586965 but is printed after the height blockchain: undefined What happens in JavaScript?

Need help trying to figure out why block contains few transactions

I'm trying to troubleshoot bitcoin block 0000000000000000001aaef7bdca12abf93c862b5df4db96ca6130b6445655c1. The Prohashing pool found this block this morning, but it only has 9 transactions. The blocks around it appear to have many more transactions than this one does, some as many as 1300. Yet, getblocktemplate returned just a few transactions. This is the third block where there were about the same number of transactions.
Since all the other coins mined by the pool contain a lot of transactions, it's unlikely that this problem is a bug in the mining server that limits blocks to 9 transactions. For example, litecoin block 9d24ac1c74689309c08f4d2bd4eb47210c8f44f4c788472fd003bf7d8d4ad562 contains 19 transactions. Bitcoin Cash block 000000000000000000c966e7c0f566df540efc2b30604188a7cf511cb8e41730 also contains more than 9 transactions. That's why I think the problem is a configuration error.
Here's the bitcoin.conf file, in case that helps.
server=1 daemon=1 port=4516 rpcuser=daemon rpcpassword=[censored] rpcport=3210 rpctimeout=30 blocknotify=/usshare/blocknotify_new.sh --user=daemon --pass=[censored] #maxconnections=8 txconfirmtarget=6 minrelaytxfee=0.00005 addnode=v4.us-east.fibre.bitcoinrelaynetwork.org 
and here's what getinfo() returns:
{ "version": 1000300, "protocolversion": 80002, "walletversion": 60000, "balance": 15.98119571, "blocks": 534848, "timeoffset": 0, "connections": 27, "proxy": "", "difficulty": 5949437371609.53, "testnet": false, "keypoololdest": 1529134290, "keypoolsize": 100, "unlocked_until": 0, "paytxfee": 0.00000000, "relayfee": 0.00002423, "errors": "Warning: unknown new rules activated (versionbit 1)" } 
While a lot of discussion here is about BCH, all of our employees are banned from all of the Core's discussion forums, so this is the only place we can go. Any help someone can provide would be appreciated, as including more transactions in blocks would also allow the networks to function better for everyone.

Soo after almost 3 months of setting up I have my own LN full node running on RP3

Soo after almost 3 months of setting up I have my own LN full node running on RP3
I have been eager to try LN mainnet since the very beginning of it. I've found out about lnd, eclair, zap and other wallets but every scenario I tried to use it failed because of critical issues:
  • eclair does not really constitute a wallet, it's more like a credit card - you can send money but not receive it
  • lnd is okay, but requires a server and tons of resources for maintaining a full node, can't be used securely, efficiently and mobily at the same time
  • zap offers some cloud wallet (in testnet!) by default, this is a serious misunderstanding of my cryptoanarchy needs
  • web wallets - ah, forget it
So I've decided to use my Raspberry Pi with a very old laptop HDD attached (200GB so the pruning function has to be used) to create a backend wallet service and zap desktop (temporarily!) as my frontend control panel.
Setting up Pi is easy, lots of tutorials over the internet, not gonna discuss it here. Then I had to obtain bitcoind (current rel: bitcoin-0.17.0-arm-linux-gnueabihf.tar.gz) and lnd (lnd-linux-armv7-v0.5-beta.tar.gz), create a bitcoin technical user, deploy the tools, configure and install new systemd services and go through the configs. This is a tricky part, so let's share:
# Generated by https://jlopp.github.io/bitcoin-core-config-generato # This config should be placed in following path: # ~/.bitcoin/bitcoin.conf # [core] # Set database cache size in megabytes; machines sync faster with a larger cache. Recommend setting as high as possible based upon machine's available RAM. dbcache=100 # Keep at most  unconnectable transactions in memory. maxorphantx=10 # Keep the transaction memory pool below  megabytes. maxmempool=50 # Reduce storage requirements by only storing most recent N MiB of block. This mode is incompatible with -txindex and -rescan. WARNING: Reverting this setting requires re-downloading the entire blockchain. (default: 0 = disable pruning blocks, 1 = allow manual pruning via RPC, greater than 550 = automatically prune blocks to stay under target size in MiB). prune=153600 # [network] # Maintain at most N connections to peers. maxconnections=40 # Use UPnP to map the listening port. upnp=1 # Tries to keep outbound traffic under the given target (in MiB per 24h), 0 = no limit. maxuploadtarget=5000 # [debug] # Log IP Addresses in debug output. logips=1 # [rpc] # Accept public REST requests. rest=1 # [wallet] # Do not load the wallet and disable wallet RPC calls. disablewallet=1 # [zeromq] # Enable publishing of raw block hex to 
. zmqpubrawblock=tcp:// # Enable publishing of raw transaction hex to
. zmqpubrawtx=tcp:// # [rpc] # Accept command line and JSON-RPC commands. server=1 # Username and hashed password for JSON-RPC connections. The field comes in the format: :$. RPC clients connect using rpcuser=/rpcpassword= arguments. You can generate this value with the ./share/rpcauth/rpcauth.py script in the Bitcoin Core repository. This option can be specified multiple times. rpcauth=xxx:yyy$zzz
Whooaa, this online config generator is really helpful, but I still had to manually correct a few things. The last line is obviously generated by rpcauth.py, I disabled the wallet functionality as lnd is going to take care of my funds. ZMQ is not available to the network so only my LND can use it, RPC usage I still have to think through a little, in general I would like to have my own block explorer some day but also be safe from any hacking attempts (thus I would need at least 2 RPC ports/user accounts - one for lnd, one for block explorer frontend). No ports open on firewall at this time, only UPnP is active and gently opens 8333 for block/tx transfers.
Now, synchronizing the blockchain took me time from mid-July to early September... The hard drive is really slow, also my external HDD drive has some trouble with its A/C adapter so Pi was getting undervoltage alerts all the time. Luckily, it is just downclocking when it happens and slowly but steadily synchronized the whole history. After all, I'm not paying even $5 monthly for a VPS, it is by design the cheapest hardware I could use to set up my LN wallet.
When bitcoind was ready (I've heard some stories about btcd but I don't trust this software yet, sorry), it's time to configure lnd.conf:
[Application Options] debuglevel=trace rpclisten= externalip=X.X.X.X:9735 listen= alias=X color=#XXXXXX [Bitcoin] bitcoin.active=1 bitcoin.mainnet=1 bitcoin.node=bitcoind [Bitcoind] bitcoind.rpchost= bitcoind.rpcuser=X bitcoind.rpcpass=X bitcoind.zmqpubrawblock=tcp:// bitcoind.zmqpubrawtx=tcp:// 
Here I've had to XXX a little more fields, as not only the bitcoind RPC credentials are stored here, but also my node's public information (it should be illegal to run nodes without specifically selected color and alias!). It is public (and I had to open port 9735 on my firewall), but not necessarily connected to my reddit account for most of the adversaries, so let's keep it this way. In fact, I also see a security vulnerability here: my whole node's stability depends on the IP being static. I could swap it for a .tk domain but who can tell if the bad guys won't actively fight DNS system in order to prevent global economic revolution? As such, I would rather see node identification in LN based on a public key only with possible *hints* of last-known-ip-address but the whole discovery should be performed by the nodes themself in a p2p manner, obviously preventing malicious actors from poisoning the network in some way. For now, I consider the IP stability a weak link and will probably have to pay extra Bitcoin TX fees when something happens to it (not much of a cost luckily!).

Okay then, lnd is up and running, had to create a wallet and give it a night for getting up to speed. I don't know really what took it so long, I'm not using Windows nor 'localhost' in the config so the issues like #1027 are not the case. But there are others like #1545 still open so I'm not going to ponder much on this. I haven't really got any idea how to automatically unlock the wallet after Pi restart (could happen any time!), especially since I only tried to unlock it locally with lncli (why would I enter the password anywhere outside that host?), but let's say that my wallet will only be as stable as my cheap hardware. That's okay for the beta phase.
Finally, zap-desktop required me to copy tls.cert and admin.macaroon files to my desktop. If my understanding of macaroon (it's like an authentication cookie, that can later be revoked) is correct then it's not an issue, however it would be nice to have a "$50 daily limit" macaroon file in the future too, just to avoid any big issues when my client machine gets stolen. Thanks to this, I can ignore the silly cloud-based modes and have fully-secure environment of my home network being the only link from me to my money.
Aaand there it is. The IP took some time to advertise, I use 1ml.com to see if my node is there. The zap interface (ZapDesktop-linux-amd64-v0.2.2-beta.deb) lacks lots of useful information so I keep learning lncli syntax to get more data about my new peers or the routes offered. The transactions indeed run fast and are ridiculously cheap. I would really love to run Eclair with the same settings but it doesn't seem to support custom lnd (why?). In fact, since all I need is really a lncli wrapper, maybe it will be easy to write my own (seen some web gui which weighs 700MB after downloading all dependencies with npm - SICK!). Zap for iOS alpha test registration is DOWN so I couldn't try it (and I'm not sure if it allows custom lnd selection), Zap for Android doesn't even exist yet... I made a few demo transactions and now I will explore all those fancy t-shirt stores as long as the prices are still in "early investor" mode - I remember times when one could get 0.001 BTC from a faucet...
If you find any of the facts presented by me false, I am happy to find out more in the discussion. However what I did I did mostly for fun, without paying much attention to the source code, documentation and endless issue lists on github. By no means I claim this tutorial will work for you but I do think I shared the key points and effort estimations to help others decide if they want a full-node LN client too. I'm also interested in some ideas on what to do with it next (rather unlikely that I will share my lnd admin.macaroon with anyone!) especially if it gives me free money. For example, I can open 1000 channels and start earning money from fees, although I no longer have more Bitcoins than the LN capacity yields... I will probably keep updating the software on my Pi until it leaves beta phases and only then will pour more money inside. I'm also keen on improving the general security of my rig and those comments I will answer more seriously.

Notes on a first quick test of NTumblebit, on Linux and regtest.

I just thought I'd jot down a few notes on the experience of trying out the current NTumbleBit code.
This is testing on regtest, done for the simple reason that you don't have to wait for testnet blocks (nor sync testnet which is mildly annoying). At this stage I just wanted to learn how this works.
Your starting point is this wiki page.


You need to download Bitcoin Core. Use at least 0.13.1 - this turned out to be only major blocking point in the whole test, funnily enough, for me - it took me a few hours(!) in debugging to realize that the reason my wallet's coins were not being recognized was simply because 0.12.1 didn't support the necessary RPC syntax. (Note to devs: is there a way to expose errors/exception to the user in the client to help with under-the-hood errors like that? RPC configuration errors are exposed, so that's good of course).
Since this is regtest, that's it: you don't need to sync any blockchains :)
However, you do of course have to configure and start it. Put a bitcoin.conf somewhere (if you're currently running a node it's easiest to make a separate one from your main ~/.bitcoin/bitcoin.conf one, of course. I put one in ~/bitcoin.conf with these settings:
rpcuser=bitcoinrpc rpcpassword=123456abcdef 
(you'll need those values again in a minute) and then run with
~/bitcoininstallationdibitcoind -regtest -daemon -conf=homedibitcoin.conf 
(I didn't need to add server=1 to config).
Note that coins are not available until maturity, so you need to use the generate command to mine blocks, like this:
~/bitcoininstallationdibitcoin-cli -regtest -rpcuser=bitcoinrpc -rpcpassword=123456abcdef generate 101 
Now your regtest bitcoind is running, you can move on to Tumblebit. Follow the instructions in the wiki page mentioned at the start; install .Net Core - the Microsoft instructions are easy to follow, just a couple of apt-gets and install the *.deb. Next, clone the github repo and run the Unit Tests. They passed first time for me.


Next, start up the server, following the instructions in the wiki, except note you're using regtest, so:
cd NTumbleBit.TumblerServer dotnet run -regtest 
The first start up will compile but also set up RSA keys, all that is fine without changes, but you'll need to edit the config so that the RPC is pointing at your regtest instance properly. In this case it (the new config should be located in ~/.ntumblebit/RegTest/server.config) should be edited to look like:
rpc.url=http://localhost:18332/ rpc.user=bitcoinrpc rpc.password=123456abcdef #rpc.cookiefile=yourbitcoinfolde.cookie 
Then restart and check you get no RPC errors. Leave that console open, it's running a server loop.
Next, configure and start the client. Note, we are still following the wiki page, except for the regtest element, so:
cd NTumbleBit.CLI dotnet run -regtest 
You'll most likely get an RPC error again, before it shuts down. Now we need to edit the ~/.ntumblebit/RegTest/client.config file. The server can be left as the default localhost:5000, but you need the right RPC settings:
rpc.url=http://localhost:18332/ rpc.user=bitcoinrpc rpc.password=123456abcdef #rpc.cookiefile=yourbitcoinfolde.cookie tumbler.server=http://localhost:5000 outputwallet.extpubkey= outputwallet.keypath=0 
the last two fields are the important bit, which the wiki page explains in some detail for the testnet case.

Details on setting up a receiving wallet (for this test!)

What you need is a BIP32 based wallet (HD) that supports testnet, and can be run against regtest here (which in most cases will be the same thing to a wallet, as long as it can connect via RPC to sync itself). The good news is the wallet doesn't need to contain any coins. The details of the following probably won't be suitable for most (if you've never used joinmarket it's a bit convoluted), so you'll probably want to find another easy to use wallet; the wiki page should be a good starting point.
For my test I used joinmarket; all we need to do is (a) hook it up to the regtest instance, and (b) extract the BIP32 xpub key that we'll be sending coins to. So in my case the flow of coins is:
Regtest Bitcoin Core wallet (containing 'mined' coins) one branch of my BIP32 joinmarket wallet, configured to sync against the same regtest instance.
I used my new joinmarket code but it's the same for the main joinmarket code. I overwrote joinmarket.cfg to have regtest settings (use this file; only the highlighted settings matter, those are the right ones for this test), then just run python wallet-tool.py randomseed. "randomseed" there can be literally anything, it's read as a brainwallet style seed for the bip32 wallet (because testnet, we don't care about its insecurity). The tpub.. keys seen for each branch are the "xpub" public keys at that branch of the BIP32 wallet. Tumblebit is going to send to a branch below whatever xpub we need, so the simplest is to add a print statement to print the xpub key above that; e.g. add this code:
for i in range(max_mix_depth): print('master for index: ' + str( i) + ' : ' + btc.bip32_privtopub(mixing_depth_keys[i])) 
immediately above this line. Then run again python wallet-tool.py randomseed.
Extract an xpub for any one of the "mixdepths", e.g. I chose:
master for index: 3 : tpubDBFGvUbWtEPKXeWPeG7rUh98iV9GuXSDbnk6ZrZHjcmp134BPByT293HPPQ93DktrVFKpZeAU1ULSdyfmwWuUGvUVLP19JkdUq2mzNKFJPR 
and put that tpub.. key into the field pubkey in the above mentioned 'client.config':
outputwallet.extpubkey=tpubDBFGvUbWtEPKXeWPeG7rUh98iV9GuXSDbnk6ZrZHjcmp134BPByT293HPPQ93DktrVFKpZeAU1ULSdyfmwWuUGvUVLP19JkdUq2mzNKFJPR outputwallet.keypath=0 
Now save and quit.

Running the tumble

Restart the client. If RPC is right, it'll start running, waiting for blocks. Your regtest Core instance will have coins (after the previous generate 101), and those coins will be automatically tumbled, one coin at a time, into the output wallet (in my case, the branch m/0/3/0 which is labelled there 'mixdepth 3, external').
Now you can test and watch the process! Open up a third console and repeatedly generate blocks:
/path/to/bitcoin/bin/bitcoin-cli -regtest -rpcpassword=123456abcdef generate 1 
As each block is generated you'll see the state in the client terminal window updating, showing the phases. A new 'epoch' (right term?) is started every N blocks (I haven't investigated the timing yet), and several epochs run concurrently. In each one, the client can pay in 1 Bitcoin (from Core) and eventually get out 1 coin - fees to the destination (Joinmarket in my case, any other BIP32 in yours). You can replace generate 1 with generate N but I'm not sure if the code will always correctly handle you mining lots of blocks at once! After a large enough number of blocks you'll start to see 'ClientCashout phase' occurring, and txids being printed out. You can go back to your (JM or other) wallet and see the coins arriving; here's what I see after a few epochs have gone through (using my python wallet-tool.py randomseed command):
for mixdepth=2 balance=0.00000000btc mixing depth 3 m/0/3/ external addresses m/0/3/0 tpubDDMAxSHJmxzeXwDnATuvtDizqNSsQKpXGufBDnER44BzEbHy7kg485zZwHqvzprgf6yEQYg9qYYfsLYS1HMmdSuXDzQb2dJSiga9geyM62R m/0/3/0/007 mw9s7tYucxB9yr2L6HkqeDVsh3wdgMdcyK used 0.99995750 btc m/0/3/0/008 mq5TgTNgwYHv88Q4T7wL6kTb1MBSPE3mqK used 0.99995750 btc m/0/3/0/009 mhzQFY8FNvux6SKWKLKmhBB3Sw4MLaSnyu used 0.99995750 btc m/0/3/0/010 mrYECmCf5UKa1BBRMuzprVugsCi9z7oiHo new 0.00000000 btc m/0/3/0/011 mopUNXmHT8ngfBymM3c3EYMg7RLZAf6Zc6 new 0.00000000 btc m/0/3/0/012 mmaVXVfQP4UAYJPhMpQ3FhgXfHzujaxyw4 new 0.00000000 btc m/0/3/0/013 mzYD1AcUFz8SVwJM8EjVCfEM6pcYnHooBR new 0.00000000 btc m/0/3/0/014 my5unLCEMWQBkXBdeJ75VVGk1wrMrT8iDE new 0.00000000 btc m/0/3/0/015 muA76YSTtKKmD6HnVKYhkd9K9TZnPLh8pp new 0.00000000 btc internal addresses m/0/3/1 for mixdepth=3 balance=2.99987250btc

How can I make test-net?

I've tried to make test-net for mining pool test. There's no information or seed node for testnet. and find reddit and add testnet node to conf, but, testnode ip is very old , not working now. Is there latest information for make testnet? thanks,
my config also have a testnet=1 addnode=nz.nutty.one:20888 from searched community .

FreeBSD node + ban 2x nodes script

For those of us that are running FreeNAS at home, I figured out how to adapt THIS ban script for our FreeBSD systems. Create a new jail, (I named mine node) configure your router for your jail to get a static lease and port forward 8333.

Access your terminal and log in. I use [PuTTY](www.putty.org) since my FreeBSD server is headless. Switch to your jail with the following:

jexec (JID of your node) tcsh

Now Get installing!

Pkg update
Pkg upgrade
pkg install bitcoin-daemon bitcoin-utils nano

Lets configure bitcoin-cli!

cd uslocal/etc
nano bitcoin.conf

Now lets configure the bitcoin-daemon

cd /root
cd .bitcoin
nano bitcoin.conf

make bitcoind run on startup

cd /.
cd etc
nano rc.conf

If you already have a node running, start here for the ban script

pkg install jq wget bash
git clone https://github.com/mariodian/ban-segshit8x-nodes.git
cd ban-segshit8x-nodes
nano ban.sh

replace first line with:

chmod +x ban.sh

To see a report of current banned IPs from the bitcoin daemon, type

bitcoin-cli listbanned

Now lets set up a cronjob to execute this script on a daily basis. First lets change crontab's editor to nano:

setenv VISUAL /uslocal/bin/nano
crontab -e
@daily /ban-segshit8x-nodes/ban.sh

To view a list of all jobs, type

crontab -l

To remove a cron job, edit crontab with the same command above:

crontab -e

My next project is to get bitcoind-ncurses terminal front end working...

Why is does it take so long to shut down an node used only as a JSON-RPC server?

I'm trying to sync a full node that will only be used as a JSON-RPC server (no mining). I tried to modify the config file and added a service unit, so that the node can run in a low-end VPS with minimum RAM and CPU capabilities. The problem is that the server takes too long to stop, and it's terminated by the system, so it always start rewinding blocks that have been already downloaded.
Here is my configuration file:
server=1 daemon=1 #debug=mempool debug=rpc # If run on the test network instead of the real bitcoin network # testnet=1 # You must set rpcuser and rpcpassword to secure the JSON-RPC api # Please make rpcpassword to something secure, `5gKAgrJv8CQr2CGUhjVbBFLSj29HnE6YGXvfykHJzS3k` for example. # Listen for JSON-RPC connections on  (default: 8332 or testnet: 18332) rpcuser=myuser rpcpassword=pypassword rpcport=8332 # Enable blocks pruning #prune=550 # Limit dbcache=50 maxconnections=4 rpcthreads=2 
And the service unit:
# It is not recommended to modify this file in-place, because it will # be overwritten during package upgrades. If you want to add further # options or overwrite existing ones then use # $ systemctl edit bitcoind.service # See "man systemd.service" for details. # Note that almost all daemon options could be specified in # /etc/bitcoin/bitcoin.conf [Unit] Description=Bitcoin daemon After=network.target [Service] ExecStart=/usbin/bitcoind -daemon=0 -datadir=/home/jsonrpc/bitcoin -conf=/home/jsonrpc/bitcoin/settings.conf ExecStop=/usbin/bitcoin-cli -datadir=/home/jsonrpc/bitcoin -conf=/home/jsonrpc/bitcoin/settings.conf stop # Creates /run/bitcoind owned by bitcoin #RuntimeDirectory=/home/jsonrpc/bitcoin WorkingDirectory=/home/jsonrpc/bitcoin User=jsonrpc Group=jsonrpc TimeoutStopSec=15m #CPUQuota=4% #MemoryLimit=128M #IOReadIOPSMax=10 #IOWriteIOPSMax=10 Type=simple #Restart=on-failure # Hardening measures #################### # Provide a private /tmp and /vatmp. PrivateTmp=true # Mount /usr, /boot/ and /etc read-only for the process. ProtectSystem=full # Disallow the process and all of its children to gain # new privileges through execve().

A simple guide to financial sovereignty (set up your Bitcoin fullnode)

In 2009, a 9 pages white paper by satoshi Nakamoto described a protocol that made central banking obselete. It's a new paradigm where monney is no longer controlled by a few, but by the whole network.
The shift is already happening, as we speak, even if it's hard to see, especially if you lack the fundamental knowledege of cryptoghraphy, game theory and economics. It's just a matter of time before you realize that Bitcoin is hard money, and for the first time we have a framework to apply austrian economics, without permission. Time to reset the keynesian monopoly game.
I don't think people are inherently bad, it's just that in the actual system (which I call the legacy system) people are incentivised to make decisions that are good from their individual perspective, but unfortunately, the sum of those individual decisions are bad from the collective group perspective. That's just plain simple game theory. What makes Bitcoin so special is it's perfectly aligned set of incentives that makes individuals and collectives outcomes better. It switches the economic model from keynesian to austrian, inflation to deflation, spending to saving, modern slavery (throught debt) to financial sovereingty, de-evolution to evolution. We are currently shifting from fiat to Bitcoin.
What you think capitalism is has nothing to do with what Capitalism really is in a free market. Capitalism is beautiful, it's simply the act of evolution, saving and optimising for consumming only what's needed (don't forget with live in a world with limited ressources, yes we all forgot). Stop spending and start capitalising, that's what we should be doing. But it's near impossible in a world run by socialists imposing debt using violence. What do you think back the US dollar ? gold ? no no, only tanks, aircraft carriers, soldiers and corrupt politicians.
Our only way out of this madness with the minimum violence is Bitcoin.
To be clear, if you dont run a fullnode, then you don't validate the transactions yourself (which is one purpose of running a fullnode). If you don't do the job yourself, then you have no other choice then to trust someone else for it. That's not necesserely a bad thing, as long as you are aware of it. You have no say in what defines Bitcoin, you enforce no rules. You serve no purpose in the Bitcoin realm. Why not !
Now if you seek financial sovereignty and want to take part in the new money paradigm, you will need to operate a fullnode and get your hands a little dirty. This guide hopefuly will take you there while walking you through the steps of setting up your autonomous Bitcoin Core full node.
Why Bitcoin Core ? simply because the Bitcoin core client implement and enforce the set of rules that I myself define as being Bitcoin.



Choose & download the latest binaries for your platform directly from github: https://bitcoincore.org/bin/bitcoin-core-0.16.2
at the time of writing, the latest bitcoin core version is 0.16.2
wget https://bitcoincore.org/bin/bitcoin-core-0.16.2/bitcoin-0.16.2-x86_64-linux-gnu.tar.gz tar -zxvf bitcoin-0.16.2-x86_64-linux-gnu.tar.gz sudo mv bitcoin-0.16.2/bin/* /uslocal/bin/ rm -rf bitcoin-0.16.2-x86_64-linux-gnu.tar.gz bitcoin-0.16.2 # clean 


Make sure the needed ports (8333, 8332) are open on your server. If you don't know, you can & should use a firewall on your server. I use ufw, which stands for uncomplicated firewall.
sudo apt install ufw # install ufw 
configure default rules & enable firewall
sudo ufw default deny incoming sudo ufw default allow outgoing sudo ufw allow ssh # if you operate your server via ssh dont forget to allow ssh before enabling sudo ufw enable 
Once your firewall is ready, open the bitcoin ports :
sudo ufw allow 8333 # mainnet sudo ufw allow 8332 # mainnet rpc/http sudo ufw allow 7000 # netcat transfert (for trusted sync) 
check your firewall rules with sudo ufw status numbered


Start bitcoind so that it create the initial ~/.bitcoin folder structure.
bitcoind& # launch daemon (the & run the copmmand in the background) bitcoin-cli stop # stop the daemon once folder structure is created 


In my case, for a personnal fullnode, I want to run a full txindexed chain. We only live once and i want all options to be possible/available :) If you plan to interact with the lightning network in the future and want to stay 100% trustless, I encourage you txindexing the chain (because you'll need an indexed chain). it's not hard to txindex the chain later on, but the less you touch the data, the better. so always better to start with txindex=1 if you want to go for the long run. It only adds 26Go on top of the 200Go non indexed chain. So it's worth it !
Just to get an idea of the size of the bitcoin core chain (August 23, 2018) :
network folder txindexed height size
mainnet blocks + chainstate yes 538.094 209Go + 2.7Go = 221.7
mainnet blocks + chainstate no 538.094 193Go + 2.7Go = 195.7Go
testnet blocks + chainstate yes - -
testnet blocks + chainstate no 1.407.580 20Go + 982Mo = 21Go
Create a bitcoin.conf config file in the ~/.bitcoin folder. This is my default settings, feel free to adjust to your need. [ see full config Running Bitcoin - Bitcoin Wiki ]
# see full config here https://en.bitcoin.it/wiki/Running_Bitcoin # Global daemon=1 txindex=1 rpcallowip= # bind network interface to local only for now server=1 rest=1 # RPC rpcport=8332 rpcuser=admin rpcpassword=password # define a password rpcworkqueue=100 # zmq zmqpubrawblock=tcp://*:8331 zmqpubrawtx=tcp://*:8331 #zmqpubhashblock=tcp://*:8331 #zmqpubhashtx=tcp://*:8331 # numbers of peers. default to 125 maxconnections=10 # utxo cache. default to 300M dbcache=100 # Spam protection limitfreerelay=10 minrelaytxfee=0.0001 

Sync the blockchain

There are 2 ways you can donwload/sync the bitcoin blochain :

Network sync (default)

If this is the first time you are setting up a bitcoin full node, it's the only way to trust the data. It will take time, depending on your hardware and network speed, it could vary from hours to days. You have nothing to do but leave the bitcoind daemon running. check status with bitcoin-cli getblockchaininfo, kill daemon with bitcoin-cli stop.
Remember that this is the only procedure you should use in order to sync the blockchain for the first time, as you don't want to trust anyone with that data except the network itself.

Trusted sync

Skip this chapter if this is the first you're setting up a full node.
Once you operate a fully "network trusted" node, if you'd like to operate other nodes, syncing them from your trusted node(s) will go much faster, since you simply have to copy the trusted data from server to server directly, instead of going throught the bitcoin core network sync.
You will need to transfer the chainstate & blocks directory from the ~/.bitcoin folder of one of your trusted node to the new one. The way you achieve that transfer is up to you.
At the time of writing (August 23, 2018), the txindexed blockchain (chainstate + blocks up to height 538.094) is around 220Go. Moving that quantity of data over the network is not a trivial task, but if the transfer happens between 2 reliable servers, then netcat will be great for the job. (netcat sends raw tcp packets, there is no authentification or resume feature).
Note: with netcat, if one of the servers connection is not stable, and you lose connection, you will have to start again. that's a bummer. in that case you are better of with tools like rsync or rcp that let you resume a transfer.
In order to make the transfer a simple task, make sure you do the following on both of the receiver and the sender server :
Once both your servers (receiver & sender) are netcat ready, proceed as follow :
This is the transfer times for my last data sync between 2 servers hosted at time4vps.eu (not too bad) | folder | size | transfer time | - | - | - | blocks | 209Go | 5h20 | chainstate | 2.7Go | 4min

bitcoind as a service

For ease of use and 100% uptime, simply add bitcoind to your system service manager (in my case systemd) create the file /etc/systemd/system/bitcoind.service and add the following to it :
[Unit] Description=Bitcoin daemon After=network.target [Service] User=larafale RuntimeDirectory=bitcoind Type=forking ExecStart=/uslocal/bin/bitcoind -conf=/home/larafale/.bitcoin/bitcoin.conf ExecStop=/uslocal/bin/bitcoin-cli stop KillMode=process Restart=always RestartSec=120 TimeoutSec=240 # Hardening measures #################### # Provide a private /tmp and /vatmp. PrivateTmp=true # Mount /usr, /boot/ and /etc read-only for the process. ProtectSystem=full # Disallow the process and all of its children to gain # new privileges through execve(). NoNewPrivileges=true # Use a new /dev namespace only populated with API pseudo devices # such as /dev/null, /dev/zero and /dev/random. PrivateDevices=true # Deny the creation of writable and executable memory mappings. MemoryDenyWriteExecute=true [Install] WantedBy=multi-user.target 
Don't forget to correct the user name & the bitcoin.conf path. Once the systemd bitcoind config file is created, reload system services and start the bitcoind service:
sudo systemctl daemon-reload # reload new services sudo systemctl enable bitcoind # enable bitcoind sudo systemctl start bitcoind # start bitcoind sudo systemctl status bitcoind # check bitcoind status 
If everything worked, status should output the following:
● bitcoind.service - Bitcoin daemon Loaded: loaded (/etc/systemd/system/bitcoind.service; enabled; vendor preset: enabled) Active: active (running) since jeu. 2018-08-23 21:17:41 CEST; 5s ago Process: 5218 ExecStart=/uslocal/bin/bitcoind -conf=/home/larafale/.bitcoin/bitcoin.conf (code=exited, status=0/SUCCESS) Main PID: 5219 (bitcoind) CGroup: /system.slice/bitcoind.service └─5219 /uslocal/bin/bitcoind -conf=/home/larafale/.bitcoin/bitcoin.conf 
The bitcoind service is active and will automatically restart on statup/crash. Wait a couple minutes until the bitcoin-cli getblockchaininfo command returns the chain status. You can also query the rest interface by opening http://nodeIP:8332/rest/chaininfo.json in your browser.


You now have a full Bitcoin core node running on it's own. What's next ? Well I never blogged before, this is the first time I am outsourcing some of my work. I'm a passionnate enginner working on all kind of technologies. I've been dedicating half of my time to Bitcoin for the last 2 years already, so if this guide was usefull and want to go deeper , just let me know, depending on the feedback I get, i'll consider outsourcing more interesting work. For example next post could be about setting up an Electrum Server so you can safely use SPV wallets trusting your own fullnode.
Also I'm currently working on a trustless bitcoin payment processor called 8333, make sure you follow @_8333_ on twitter. I think I will release the project end of 2018. Ping me if interested.
The best way you can show support is via Bitcoin : 16FKGPiivpo3Z7FFPLdkoVRcV2ASBc7Ktu

[P2pool] How to make your own personal p2pool Node!

Tired of getting no block rewards and sending many dead shares? Need a p2pool node close to your miner? MAKE YOUR OWN! :D
And, Yep, P2pools give 0.5% Rewards to block finders!
Here's some info about p2ools: http://whatisp2pool.com/
The stronger the P2Pool network becomes the more resistant the digibyte network is to 51% attacks!
Oh and, P2pools are DDOS proof! Now that's News! So if your node gets DDOS'd .. you dont lose your shares as the shares have been saved in the p2pool, its called the sharechain. So you get paid anyhow! Thanks to the p2pool network. and you ccan set your workers to another pool using the "--failover only" command in cgminer (if im not wrong) and get it back to work on the p2pool network!
TL;DR; P2POOL = 1 Big fat network Decentrazlized pool!
Install Ubuntu server or Desktop if you want http://www.ubuntu.com/download/ or u can use a VPS (VirtualPrivateServer -- Link Below with coupon code)
So Let's start off in the command line (Open Terminal.. and all you have to do is Cut, Copy Paste! ;) )
Start by updating and upgrading Ubuntu, you know you want the best ;)
sudo apt-get update sudo apt-get upgrade sudo apt-get install python-software-properties sudo add-apt-repository ppa:bitcoin/bitcoin sudo apt-get update 
Time for the DigiByteProject dependencies!
sudo apt-get install build-essential libboost-all-dev libcurl4-openssl-dev libdb5.1-dev libdb5.1++-dev git qt-sdk libminiupnpc-dev sudo apt-get install qrencode libqrencode-dev 
And, Now to compile DigiByte on your system!
git clone git://github.com/digibyte/DigiByteProject.git digibyte #renaming makes it easier ;) cd ~/digibyte/src mkdir obj make -f makefile.unix USE_UPNP=- sudo cp digibyted /usbin cd ~ 
After it has compiled try running 'digibyted'
If you get an error saying you need to make the digibyte.conf file, good! :) If it doesnt give you that error, make sure you followed the compiling steps appropriately.
So, Lets create the conf file here...
cd .digibyte #edited from 'digibyted' .. fixed!! nano digibyte.conf 
Paste the following, CHANGING THE USERNAME AND PASS!! make sure to take note of both, you'll need these later!
rpcuser=CHANGEusername rpcpassword=ChangePassword daemon=1 server=1 rpcport=14022 port=12024 gen=1 rpcallowip= addnode= addnode= addnode= addnode= addnode= addnode= addnode= addnode= addnode= addnode= addnode= 
Press 'CTRL' + ' X', and then 'Y' to save when prompted
cd ~ ./digibyte/src/digibyted ./digibyte/src/digibyted getinfo 
Make sure you check the latest block in the block chain or on your local DigiByte Wallets. This is to see how far your p2pool node has gotten! This is gonna take quite a while so lets CONTINUE!
Let's get the p2pool software and frontend in! Install the p2pool dependencies!
sudo apt-get install python-zope.interface python-twisted python-twisted-web git clone https://github.com/Rav3nPL/p2pool-rav p2pool #renaming it! cd ~/p2pool/digibyte_subsidy #Thanks to Chaeplin sudo python setup.py install 
Time to edit and customise the html code to personalise your p2pool's frontend. Feel free to change the p2pool name and if you're an advanced user, feel free to add your own frontend from git hub after removing the web-static folder. (OPTIONAL: by using rm -f -r web-static #in that directory. And then you can choose whichever frontend you want! by cloning it in the web-static folder)
Editing the current frontend html!
cd .. cd web-static nano index.html 
After personalising the page, i.e. changing the p2pool name and adding some info! Lets go back and check how far the block downloading has gotten! You can check this by typing this in the command line after going back to the root directory:
cd ~ ./digibyte/src/digibyted getinfo 
This is gonna take a while so might as well check for updates again :P
sudo apt-get update sudo apt-get upgrade 
After making sure that all the blocks have been synced locally! We're ready to run the p2pool node! Simply enter the string below in the command line, entering your USERNAME and PASS that you saved earlier!
screen -d -m -S myp2pool ~/p2pool/run_p2pool.py --give-author 0 --net digibyte NEWUSER NEWPASS --outgoing-conns 4 
If you want to charge a fee for your node add this to your string, adding your fee address!:
--fee 1.0 --address NEWDGBADDRESS 
To see if the node is up and running enter this in the command line:
screen -x myp2pool 
'CTRL' + 'A' + 'D' to close the terminal if you press 'CTRL' + 'C', it will terminate the p2pool program and you'll have to restart the pool by using the string above!
Once, Everything is setup as planned! Check your p2pool node's ip Address by entering this into the command line:
inet addr: #You'll see a line like this.
So, Your cgminer string should look something like this:
cgminer --scrypt -o -u DGBADDRESS -p x
And your p2pool WEB ADDRESS should look like this:
You can monitor your p2pool using that web address! Enjoy, your personal p2pool node!! :D
If for whatever reason the server shuts off and you need to restart the p2pool node, you should run digibyted again and after it has synced successfully, just type in your p2pool string:
screen -d -m -S myp2pool ~/p2pool/run_p2pool.py --give-author 0 --net digibyte NEWUSER NEWPASS --outgoing-conns 4 --fee 1.0 --address NEWADDRESS
PRESS CTRL + A + D to Detach from screen
UPDATE Follow Guide below if you used this guide before DigibByte v2.0 was released (28th Feb 2014)
You must check whether you're on the right ShareChain. Make Sure the block Value says 7960!
This Tutorial was made with the help of an existing Guide: http://doges.org/index.php?topic=5586.0 Kudos to crypto49er!
If you want to do this on a VPS:
Here's a link to a VPS hosting site:
Feel free to use my $10 ref. code -- it doesnt really make a difference, though.

Create bitcoin full node with tor: step by step guide

This is a step by step guide for anyone that need to create a full bitcoin node through tor. This guide is for Ubuntu linux and it can apply to all linux distros
  1. Install bitcoind The first step is to install bitcoind. First we need to add ppa repositories from here https://launchpad.net/~bitcoin/+archive/ubuntu/bitcoin After that we install bitcoind with command sudo apt-get update to sync the repos and after that sudo apt-get install bitcoind
2.Install Tor Then we need to install Tor and again we add repos from official site here https://www.torproject.org/docs/debian.html.en After that we give to terminal sudo apt-get uppdate and after the sync we give sudo apt-get install tor
3.Edit bitcoin.conf file After that we need to edit a new bitcoin.conf file. in a terminal we give cd .bitcoin/ nano bitcoin.conf In this new file we add this
server=1 daemon=1 maxconnections= rpcuser=wechoosearandomusernamewithnumberandletter rpcpassword=arandompasswithnumberandletters listen=1 onlynet=tor externalip=OurOnionIp bind= proxy=
we can find our onion ip to /valib/tobitcoin-service/ and there to the file hostname The ip is a string with number,letters and it ends with .onion. To maxconnections we can add whatever connections we want to have.The limit is 120 i think
4.We edit the file /etc/totorrc and we add this entries HiddenServiceDir /valib/tobitcoin-service/ HiddenServicePort 8333 HiddenServicePort 18333
5.Finally we give to the terminal bitcoind
Tor need a half hour to sync and to accept connections We need to open 8333 port to our router so it can accept connections

How To Setup a Seed Node for Snatcoin for Free

Seed nodes are important for the strength of the Snatcoin Network. By adding a seed node you will be supporting Snatcoin and helping it grow.
These instructions below are for Windows users.
Go to https://aws.amazon.com/free and get yourself a free Amazon web services account
After you are logged into Amazon AWS select "Launch a virtual machine".
Select "get started" on EC2 Instance. After this you will name your instance
Now select a free tier eligible Ubuntu Server 16.04.
Open up a new tab for your Security Group. Click on Actions -> Edit Inbound Rules. Change Source to My IP and save. Down the bottom you should see the IP of that computer.
Launch your AWS instance, after a while on the "Instance State" tab you should see that it is running with a green dot next to it You will create a security pair key. Download this file and keep it safe.
Download Putty from https://www.putty.org/ Then install it.
Run Puttygen and convert your *.pem file to a *.ppk file
Open Putty. Make sure the port is the same port on your AWS Security Group tab. If you didn't change anything it will be 22.
Then go to Connection -> SSH -> Auth and add your *.ppk file to private key for authentication
Add in the Public IP shown in your EC2 Management Console for your virtual machine to Putty as the Host Name
Click Open on Putty. Click Yes. Then as your username use ubuntu You should now be inside your AWS virtual machine.
Install dependencies on your Ubuntu AWS Instance
sudo apt-get install git sudo apt-get install build-essential libtool autotools-dev automake pkg-config libssl-dev libevent-dev bsdmainutils sudo apt-get install libboost-system-dev libboost-filesystem-dev libboost-chrono-dev libboost-program-options- dev libboost-test-dev libboost-thread-dev sudo apt-get install libboost-all-dev sudo apt-get install software-properties-common sudo add-apt-repository ppa:bitcoin/bitcoin sudo apt-get update sudo apt-get install libdb4.8-dev libdb4.8++-dev sudo apt-get install libminiupnpc-dev sudo apt-get install libzmq3-dev sudo apt-get install libqt5gui5 libqt5core5a libqt5dbus5 qttools5-dev qttools5-dev-tools libprotobuf-dev protobuf-compiler sudo apt-get install libqt4-dev libprotobuf-dev protobuf-compiler git clone https://github.com/snatcoinOfficial/snatcoin cd snatcoin cd src 
Your instance will run out of memory on rpcbitcoin.cpp if you do not run these lines below before you compile snatcoind
sudo dd if=/dev/zero of=/swapfile bs=64M count=16 sudo mkswap /swapfile sudo swapon /swapfile 
You can now run
make -f makefile.unix 
Now you can run your snatcoind daemon
./snatcoind -daemon 
This will fail and will tell you to add some extra information to your snatcoin.conf file
Now you will have to edit your snatcoin.conf file
cd .. cd .. cd .snatcoin vi snatcoin.conf 
Now you have to set up your snatcoin.conf file in the .snatcoin directory
Add to snatcoin.conf file:
addnode= addnode= rpcuser=somethinghere rpcpassword=anythinghere 
Then save the file by typing :wq
This is to verify you wrote to your snatcoin.conf file
cat snatcoin.conf 
Now go back to your snatcoin directory and run the snatcoind
cd .. cd snatcoin ./snatcoind -daemon 
Wait for the server to load and sync up to the network
You are now connected so lets find out what else we can run from snatcoind
./snatcoind help 
On Amazon AWS select Action -> Change Instance Settings -> Change Termination Protection
Then turn termination protection on to make sure it doesn't terminate
You can now close Putty and your Instance will still be alive
The new seed node I added during this process was

Blackcoin Wallet Passphrase mistyped - Bruteforce

Summary: I executed a (limited!) brute force attack on a wallet where I mistyped the passphrase. Attached is a short tutorial how to make it.
Long story: some months ago I created a wallet. I keyed in my passphrase with 70 characters long (yes it is long), wrote it down, bought Blackcoin. Next day I tried to open it, but it seems to be that I mistyped (two times) the passphrase. So I started to make a long research how to "hack" it. I finally figured that I can make a limited brute force attack by using RPC. So, I got familiar with curl (RPC tool) and created a batch-script with Excel where I just changed one character per try. I ended with 5200 tries.
And boom: It worked! It was try number 2814 which worked. So, I really just mistyped one single character. The wallet has been opened once again. So now I have access to my Blackcoins.
I was using the old blackcoin-qt (on windows) because the wallet was created with this one. I do not know if it is compatible with lore. Situation is that you remember (more or less) the passphrase, but you think that you just mistyped one character. Idea is to make a limited brute force attack on the wallet - so, to test different passphrase which are similar to your remembered one.
we will create a script (batch) which calls the blackcoin-qt (as server) via RPC and try to open the wallet with different passphrases.
What did not work
I found some hints concerning hashcat and bitcoin2john (also for Blackcoin), which enable you to retrieve the seed out of the wallet and to make a bruteforce on the hash of the seed (with hashcat). But it did not work, because the blackcoin wallet seems to be different than the bitcoin wallet.
There is also no direct commandline parameter for opening the wallet with passphrase. So I started to work with RPC.
Using the blackcoin-qt as a server
Switch into C:\Users\myusername\AppData\Roaming\BlackCoin and place a blackcoin.conf file here. This should contain (at least) these entries:

server=1 tells BlackCoin to accept JSON-RPC commands.


You must set rpcuser and rpcpassword to secure the JSON-RPC api


Listen for RPC connections on this TCP port:


You can use BlackCoin or blackcoind to send commands to Bitcoin/bitcoindBlackCoin/blackcoind

running on another host using this option:

...Start blackcoin from the commandline with the server parameter like this: blackcoin-qt -server=1
Test RPC Calls with curl
Download curl (an RPC tool for the commandline): https://curl.haxx.se/
For this test you should use a new generated wallet with a password you know.
First test with the getinfo method, which shows you if the connection to the Blackcoin Daemon is established: curl --header "Content-Type: application/json" --data-binary "{\"jsonrpc\":\"1.0\",\"id\":\"curltest\",\"method\":\"getinfo\",\"params\":[]}" http://user:[email protected]:15715/
If you do not get any connection, you can also use netstat -a to see if your machine is listening on the port 15715.
Finally, the method to open the wallet via RPC (uses two parameters) curl --header "Content-Type: application/json" --data-binary "{\"jsonrpc\":\"1.0\",\"id\":\"curltest\",\"method\":\"walletpassphrase\",\"params\":[\"mySecretWalletPassword\",50]}" http://user:[email protected]:15715/
Note the output you get, when you use the correct password: {"result":null,"error":null,"id":"curltest"}
Later we want to search in a logfile for the expression "error":null in order to identify the correct password
Generating the Bruteforce Script
I used an Excel file to create a script. On the basis of the so-far-remembered-passphrase and a selection of possible characters this scripts changes for each row only one character. I ended up with roughly 5000 rows, but I used a very long passphrase (70 characters). Using the Excel output you can create a script out of it.
If you are interested in the Excel file you can contact me on bitcointalk - my username is "Euro1000"
Start the script (batch) and pipe the output into a log: myScript.bat > log.txt
When the batch finished search for the expression "error":null If you found it, you found the password in the line above the expression.
I used the old blackcoin-qt (not Lore), because the wallet has been generated with blackcoin-qt. Lore should use the same RPC implementation, but it is untested if this tutorial also works with Lore.
I used this on Windows I do not know if this will also work on Linux.
Some special characters are a little bit tricky in curl, because some of them like "<" let curl crashes. Perhaps you can escape these special characters somehow.
