FAQ for Beginners

What is Bitcoin?

Bitcoin is scarce, decentralized, and global digital money that cannot be censored.

Quick Advice

  • Do not respond to strangers messaging you with investment advice or offers and read how to avoid being scammed from the posts below.
  • Do not invest in Bitcoin until you do basic research, paid off all high interest debt, and have a emergency savings account of a stable fiat currency.
  • If investing do not expect to get rich quickly. You should expect to wait at least 1-2 years before taking profits. Bitcoin is currently very volatile. In the interim spend and replace Bitcoin because its a useful currency.
  • Beginners should avoid all mining and day trading until at least very familiar with Bitcoin. Mining is very professional(You cannot efficiently mine with your computer and need to buy special ASIC machines) and most people lose money day trading.
  • Never store your Bitcoins on an exchange or web wallet. Buy your bitcoins and withdraw it to your personal wallet where you actually own them instead of IOUs. Services like Robinhood, Revoult, and Etoro should be avoided because you cannot withdraw or use Bitcoin.
  • Make sure you make a backup of your wallet(software holding keys to your BTC) and preferably keep it offline and physical and private. Typically 12 to 24 words you write down on paper or metal.
  • Beginners should avoid altcoins, tokens, and ICOs at least initially until they learn about Bitcoin. Most of these are scams and you should be familiar with the basics first. Bitcoin is referred to as BTC or XBT.

Crypto Wallet Extensions: Why Easy Access for You May Also Mean Easy Access for Scammers

Crypto Wallet Extensions: Why Easy Access for You May Also Mean Easy Access for Scammers

https://preview.redd.it/3q59auglzf351.jpg?width=1400&format=pjpg&auto=webp&s=9aa76610c7345620ed7f349056bad2976298b475
For the most part, Bitcoin and crypto are areas of interest for investors looking to diversify their portfolio or engage in trading with a potentially profitable asset. However, more and more services are coming out that allow the average person to start getting into crypto (take Lolli’s crypto-back model, for example). Of course, the average person is going to be looking for the easiest ways to participate in the crypto economy, which often means reaching for wallet providers who give them quick and convenient access to their funds.
One such example of these products is the ever-popular chrome extension. While these solutions do make it more convenient to receive crypto, they often come with a major disadvantage: being scammed out of your money.
Fake Google crypto wallet extensions for Chrome are a rapidly growing problem. This is due to the fact that anyone can create a product that is almost identical to similar ones offered through the web store. In fact, some imposters were developing wallets that copied those offered by major organizations like Ledger, Electrum, and Exodus, just to name a few.
Once you download the browser extension and sign up for your wallet, the information then gets transferred over to the hacker’s server rather than Google’s. This gives hackers immediate access to your funds. While more seasoned investors and enthusiasts will know to be on their toes for any potential scams, those who are new to the industry can easily fall for these fake extensions as it can be quite hard to tell the difference.
If you are someone who is just getting into crypto (or someone who has downloaded a chrome extension in the past or plans to download one for specific needs) some great rules to follow include:
  • Making sure that you pay attention to the name of the developer and the website that it is directing you to. Some developer names will be glaringly obvious while other hackers will slightly change the website name to trick you into thinking it is authentic. If the link brings you to the wrong website that is not the one for the official company, it is a false extension.
  • Look at the quality of the content and the images listed in the description for the Chrome extension. Like the name of the developer, some fake extensions will give themselves away by using sub-par images or having multiple typos listed throughout the copy, which is something that a company is extremely unlikely to have in their own extension description.
  • Taking a look at some of the product reviews for the extension. While you should take into account that some reviews can be fake, it may be revealed that the extension is not real if you run into more than a handful of negative reviews and comments.
While Google is cracking down on these copycats, you still have to exercise caution in case one of them gets through. Using the three tips provided above is one excellent way to make sure you don’t lose your money by downloading the wrong extension.
As the price of crypto continues to rise and interest piques, making sure that you are avoiding any potential hackers is key to protecting your assets as you explore the world of cryptocurrency.

[AMA] Randy Brito here from BitcoinVenezuela.com, what we’ve been doing and why we might need your help

Hello all here, I am Randy Brito (aka @btcven), a Venezuelan whose family moved to Spain in 2004 due to the worsening situation and persecution on the middle class.
I learned about Bitcoin in 2011 and read a lot about it here and at Bitcointalk.org (and learned about Libertarianism too through it), in 2012 founded https://www.BitcoinVenezuela.com as a non-profit organization dedicated to educate about Bitcoin and basic economics.
Started collaborating with Electrum developers, translated it into Spanish (along with Hive Wallet, MacWallet, and some others). At Electrum also helped as manager of translations, website, social media, support.
Co-founded another local non-profit education group in Spain and gave talks about Bitcoin around the country, mostly in high schools to get the young people started before they even learned how to use a bank account. Also co-founded a Classic Liberal - Anarchocapitalist group in Seville, Spain where I was part of the team which hosted the Free Market Road Show three years in a row.
In 2014 joined Support at Coinbase as one of the two first employees outside the US, when it was still only serving US customers, and worked there for 3.5 years. Joined MetaMask-ConsenSys a few months ago as Customer Support.
Tried to open a Bitcoin<->Bolivar exchange between 2014-2015, we got stopped and the other local exchange there got shut down completely.
I’ve been educating about Bitcoin in Venezuela since 2012, in our website, in social media, with collaborators in the country who gave talks, supporting local groups teaching about Bitcoin there, running campaigns, giving interviews, podcasts. Besides trying to educate about economics, fighting Socialism both in Venezuela and Spain, and more.
For more than two years now I’ve been collecting donations in cryptocurrencies through our humanitarian aid project 'Bitcoin For Venezuela Initiative' to help feed people, buy medicines and help those in need. We started doing a monthly activity to cook food for 400-500 people. Today we help feed 2000+ people daily, by buying food for a soup kitchen where 1600+ people go to eat daily, probably the only meal they have in a whole day. Also cook meals for two orphanages, an elderly center, a kids hospital, and an old people’s hospital. This is the last activity we did: https://twitter.com/btcven/status/1028743266739662849?s=21
We are now also helping another soup kitchen and an elderly center in a small town, and also managing donations to restore a farm school, so it can produce food again for the towns around it, and also teach young people to work in the farm. Donations come mostly from private donators giving us cryptocurrencies, not many donations come from our public addresses (we take Bitcoin Lightning Network donations too!) because we keep most of the pictures and videos taken private because of the persecution in the country of those who do humanitarian aid, and for the safety of collaborators on the ground.
For the past months I’ve been working on speeding up Bitcoin adoption in Venezuela ( checkout these 4 tweets https://twitter.com/randybrito/status/1023679503862824962?s=21 ) through a few steps:
This project-effort is called Locha
https://twitter.com/Locha_io
We need your help and support to make this happen.

# Motivation

UTXO growth is a serious concern for Bitcoin's long-term decentralization. To
run a competitive mining operation potentially the entire UTXO set must be in
RAM to achieve competitive latency; your larger, more centralized, competitors
will have the UTXO set in RAM. Mining is a zero-sum game, so the extra latency
of not doing so if they do directly impacts your profit margin. Secondly,
having possession of the UTXO set is one of the minimum requirements to run a
full node; the larger the set the harder it is to run a full node.

Currently the maximum size of the UTXO set is unbounded as there is no
consensus rule that limits growth, other than the block-size limit itself; as
of writing the UTXO set is 1.3GB in the on-disk, compressed serialization,
which expands to significantly more in memory. UTXO growth is driven by a
number of factors, including the fact that there is little incentive to merge
inputs, lost coins, dust outputs that can't be economically spent, and
non-btc-value-transfer "blockchain" use-cases such as anti-replay oracles and
timestamping.

We don't have good tools to combat UTXO growth. Segregated Witness proposes to
give witness space a 75% discount, in part of make reducing the UTXO set size
by spending txouts cheaper. While this may change wallets to more often spend
dust, it's hard to imagine an incentive sufficiently strong to discourage most,
let alone all, UTXO growing behavior.

For example, timestamping applications often create unspendable outputs due to
ease of implementation, and because doing so is an easy way to make sure that
the data required to reconstruct the timestamp proof won't get lost - all
Bitcoin full nodes are forced to keep a copy of it. Similarly anti-replay
use-cases like using the UTXO set for key rotation piggyback on the uniquely
strong security and decentralization guarantee that Bitcoin provides; it's very
difficult - perhaps impossible - to provide these applications with
alternatives that are equally secure. These non-btc-value-transfer use-cases
can often afford to pay far higher fees per UTXO created than competing
btc-value-transfer use-cases; many users could afford to spend $50 to register
a new PGP key, yet would rather not spend $50 in fees to create a standard two
output transaction. Effective techniques to resist miner censorship exist, so
without resorting to whitelists blocking non-btc-value-transfer use-cases as
"spam" is not a long-term, incentive compatible, solution.

A hard upper limit on UTXO set size could create a more level playing field in
the form of fixed minimum requirements to run a performant Bitcoin node, and
make the issue of UTXO "spam" less important. However, making any coins
unspendable, regardless of age or value, is a politically untenable economic
change.


# TXO Commitments

A merkle tree committing to the state of all transaction outputs, both spent
and unspent, we can provide a method of compactly proving the current state of
an output. This lets us "archive" less frequently accessed parts of the UTXO
set, allowing full nodes to discard the associated data, still providing a
mechanism to spend those archived outputs by proving to those nodes that the
outputs are in fact unspent.

Specifically TXO commitments proposes a Merkle Mountain Range¹ (MMR), a
type of deterministic, indexable, insertion ordered merkle tree, which allows
new items to be cheaply appended to the tree with minimal storage requirements,
just log2(n) "mountain tips". Once an output is added to the TXO MMR it is
never removed; if an output is spent its status is updated in place. Both the
state of a specific item in the MMR, as well the validity of changes to items
in the MMR, can be proven with log2(n) sized proofs consisting of a merkle path
to the tip of the tree.

At an extreme, with TXO commitments we could even have no UTXO set at all,
entirely eliminating the UTXO growth problem. Transactions would simply be
accompanied by TXO commitment proofs showing that the outputs they wanted to
spend were still unspent; nodes could update the state of the TXO MMR purely
from TXO commitment proofs. However, the log2(n) bandwidth overhead per txin is
substantial, so a more realistic implementation is be to have a UTXO cache for
recent transactions, with TXO commitments acting as a alternate for the (rare)
event that an old txout needs to be spent.

Proofs can be generated and added to transactions without the involvement of
the signers, even after the fact; there's no need for the proof itself to
signed and the proof is not part of the transaction hash. Anyone with access to
TXO MMR data can (re)generate missing proofs, so minimal, if any, changes are
required to wallet software to make use of TXO commitments.


## Delayed Commitments

TXO commitments aren't a new idea - the author proposed them years ago in
response to UTXO commitments. However it's critical for small miners' orphan
rates that block validation be fast, and so far it has proven difficult to
create (U)TXO implementations with acceptable performance; updating and
recalculating cryptographicly hashed merkelized datasets is inherently more
work than not doing so. Fortunately if we maintain a UTXO set for recent
outputs, TXO commitments are only needed when spending old, archived, outputs.
We can take advantage of this by delaying the commitment, allowing it to be
calculated well in advance of it actually being used, thus changing a
latency-critical task into a much easier average throughput problem.

Concretely each block B_i commits to the TXO set state as of block B_{i-n}, in
other words what the TXO commitment would have been n blocks ago, if not for
the n block delay. Since that commitment only depends on the contents of the
blockchain up until block B_{i-n}, the contents of any block after are
irrelevant to the calculation.


## Implementation

Our proposed high-performance/low-latency delayed commitment full-node
implementation needs to store the following data:

1) UTXO set

Low-latency K:V map of txouts definitely known to be unspent. Similar to
existing UTXO implementation, but with the key difference that old,
unspent, outputs may be pruned from the UTXO set.


2) STXO set

Low-latency set of transaction outputs known to have been spent by
transactions after the most recent TXO commitment, but created prior to the
TXO commitment.


3) TXO journal

FIFO of outputs that need to be marked as spent in the TXO MMR. Appends
must be low-latency; removals can be high-latency.


4) TXO MMR list

Prunable, ordered list of TXO MMR's, mainly the highest pending commitment,
backed by a reference counted, cryptographically hashed object store
indexed by digest (similar to how git repos work). High-latency ok. We'll
cover this in more in detail later.


### Fast-Path: Verifying a Txout Spend In a Block

When a transaction output is spent by a transaction in a block we have two
cases:

1) Recently created output

Output created after the most recent TXO commitment, so it should be in the
UTXO set; the transaction spending it does not need a TXO commitment proof.
Remove the output from the UTXO set and append it to the TXO journal.

2) Archived output

Output created prior to the most recent TXO commitment, so there's no
guarantee it's in the UTXO set; transaction will have a TXO commitment
proof for the most recent TXO commitment showing that it was unspent.
Check that the output isn't already in the STXO set (double-spent), and if
not add it. Append the output and TXO commitment proof to the TXO journal.

In both cases recording an output as spent requires no more than two key:value
updates, and one journal append. The existing UTXO set requires one key:value
update per spend, so we can expect new block validation latency to be within 2x
of the status quo even in the worst case of 100% archived output spends.


### Slow-Path: Calculating Pending TXO Commitments

In a low-priority background task we flush the TXO journal, recording the
outputs spent by each block in the TXO MMR, and hashing MMR data to obtain the
TXO commitment digest. Additionally this background task removes STXO's that
have been recorded in TXO commitments, and prunes TXO commitment data no longer
needed.

Throughput for the TXO commitment calculation will be worse than the existing
UTXO only scheme. This impacts bulk verification, e.g. initial block download.
That said, TXO commitments provides other possible tradeoffs that can mitigate
impact of slower validation throughput, such as skipping validation of old
history, as well as fraud proof approaches.


### TXO MMR Implementation Details

Each TXO MMR state is a modification of the previous one with most information
shared, so we an space-efficiently store a large number of TXO commitments
states, where each state is a small delta of the previous state, by sharing
unchanged data between each state; cycles are impossible in merkelized data
structures, so simple reference counting is sufficient for garbage collection.
Data no longer needed can be pruned by dropping it from the database, and
unpruned by adding it again. Since everything is committed to via cryptographic
hash, we're guaranteed that regardless of where we get the data, after
unpruning we'll have the right data.

Let's look at how the TXO MMR works in detail. Consider the following TXO MMR
with two txouts, which we'll call state #0:

0
/ \
a b

If we add another entry we get state #1:

1
/ \
0 \
/ \ \
a b c

Note how it 100% of the state #0 data was reused in commitment #1. Let's
add two more entries to get state #2:

2
/ \
2 \
/ \ \
/ \ \
/ \ \
0 2 \
/ \ / \ \
a b c d e

This time part of state #1 wasn't reused - it's wasn't a perfect binary
tree - but we've still got a lot of re-use.

Now suppose state #2 is committed into the blockchain by the most recent block.
Future transactions attempting to spend outputs created as of state #2 are
obliged to prove that they are unspent; essentially they're forced to provide
part of the state #2 MMR data. This lets us prune that data, discarding it,
leaving us with only the bare minimum data we need to append new txouts to the
TXO MMR, the tips of the perfect binary trees ("mountains") within the MMR:

2
/ \
2 \
\
\
\
\
\
e

Note that we're glossing over some nuance here about exactly what data needs to
be kept; depending on the details of the implementation the only data we need
for nodes "2" and "e" may be their hash digest.

Adding another three more txouts results in state #3:

3
/ \
/ \
/ \
/ \
/ \
/ \
/ \
2 3
/ \
/ \
/ \
3 3
/ \ / \
e f g h

Suppose recently created txout f is spent. We have all the data required to
update the MMR, giving us state #4. It modifies two inner nodes and one leaf
node:

4
/ \
/ \
/ \
/ \
/ \
/ \
/ \
2 4
/ \
/ \
/ \
4 3
/ \ / \
e (f) g h

If an archived txout is spent requires the transaction to provide the merkle
path to the most recently committed TXO, in our case state #2. If txout b is
spent that means the transaction must provide the following data from state #2:

2
/
2
/
/
/
0
\
b

We can add that data to our local knowledge of the TXO MMR, unpruning part of
it:

4
/ \
/ \
/ \
/ \
/ \
/ \
/ \
2 4
/ / \
/ / \
/ / \
0 4 3
\ / \ / \
b e (f) g h

Remember, we haven't _modified_ state #4 yet; we just have more data about it.
When we mark txout b as spent we get state #5:

5
/ \
/ \
/ \
/ \
/ \
/ \
/ \
5 4
/ / \
/ / \
/ / \
5 4 3
\ / \ / \
(b) e (f) g h

Secondly by now state #3 has been committed into the chain, and transactions
that want to spend txouts created as of state #3 must provide a TXO proof
consisting of state #3 data. The leaf nodes for outputs g and h, and the inner
node above them, are part of state #3, so we prune them:

5
/ \
/ \
/ \
/ \
/ \
/ \
/ \
5 4
/ /
/ /
/ /
5 4
\ / \
(b) e (f)

Finally, lets put this all together, by spending txouts a, c, and g, and
creating three new txouts i, j, and k. State #3 was the most recently committed
state, so the transactions spending a and g are providing merkle paths up to
it. This includes part of the state #2 data:

3
/ \
/ \
/ \
/ \
/ \
/ \
/ \
2 3
/ \ \
/ \ \
/ \ \
0 2 3
/ / /
a c g

After unpruning we have the following data for state #5:

5
/ \
/ \
/ \
/ \
/ \
/ \
/ \
5 4
/ \ / \
/ \ / \
/ \ / \
5 2 4 3
/ \ / / \ /
a (b) c e (f) g

That's sufficient to mark the three outputs as spent and add the three new
txouts, resulting in state #6:

6
/ \
/ \
/ \
/ \
/ \
6 \
/ \ \
/ \ \
/ \ \
/ \ \
/ \ \
/ \ \
/ \ \
6 6 \
/ \ / \ \
/ \ / \ 6
/ \ / \ / \
6 6 4 6 6 \
/ \ / / \ / / \ \
(a) (b) (c) e (f) (g) i j k

Again, state #4 related data can be pruned. In addition, depending on how the
STXO set is implemented may also be able to prune data related to spent txouts
after that state, including inner nodes where all txouts under them have been
spent (more on pruning spent inner nodes later).


### Consensus and Pruning

It's important to note that pruning behavior is consensus critical: a full node
that is missing data due to pruning it too soon will fall out of consensus, and
a miner that fails to include a merkle proof that is required by the consensus
is creating an invalid block. At the same time many full nodes will have
significantly more data on hand than the bare minimum so they can help wallets
make transactions spending old coins; implementations should strongly consider
separating the data that is, and isn't, strictly required for consensus.

A reasonable approach for the low-level cryptography may be to actually treat
the two cases differently, with the TXO commitments committing too what data
does and does not need to be kept on hand by the UTXO expiration rules. On the
other hand, leaving that uncommitted allows for certain types of soft-forks
where the protocol is changed to require more data than it previously did.


### Consensus Critical Storage Overheads

Only the UTXO and STXO sets need to be kept on fast random access storage.
Since STXO set entries can only be created by spending a UTXO - and are smaller
than a UTXO entry - we can guarantee that the peak size of the UTXO and STXO
sets combined will always be less than the peak size of the UTXO set alone in
the existing UTXO-only scheme (though the combined size can be temporarily
higher than what the UTXO set size alone would be when large numbers of
archived txouts are spent).

TXO journal entries and unpruned entries in the TXO MMR have log2(n) maximum
overhead per entry: a unique merkle path to a TXO commitment (by "unique" we
mean that no other entry shares data with it). On a reasonably fast system the
TXO journal will be flushed quickly, converting it into TXO MMR data; the TXO
journal will never be more than a few blocks in size.

Transactions spending non-archived txouts are not required to provide any TXO
commitment data; we must have that data on hand in the form of one TXO MMR
entry per UTXO. Once spent however the TXO MMR leaf node associated with that
non-archived txout can be immediately pruned - it's no longer in the UTXO set
so any attempt to spend it will fail; the data is now immutable and we'll never
need it again. Inner nodes in the TXO MMR can also be pruned if all leafs under
them are fully spent; detecting this is easy the TXO MMR is a merkle-sum tree,
with each inner node committing to the sum of the unspent txouts under it.

When a archived txout is spent the transaction is required to provide a merkle
path to the most recent TXO commitment. As shown above that path is sufficient
information to unprune the necessary nodes in the TXO MMR and apply the spend
immediately, reducing this case to the TXO journal size question (non-consensus
critical overhead is a different question, which we'll address in the next
section).

Taking all this into account the only significant storage overhead of our TXO
commitments scheme when compared to the status quo is the log2(n) merkle path
overhead; as long as less than 1/log2(n) of the UTXO set is active,
non-archived, UTXO's we've come out ahead, even in the unrealistic case where
all storage available is equally fast. In the real world that isn't yet the
case - even SSD's significantly slower than RAM.


### Non-Consensus Critical Storage Overheads

Transactions spending archived txouts pose two challenges:

1) Obtaining up-to-date TXO commitment proofs

2) Updating those proofs as blocks are mined

The first challenge can be handled by specialized archival nodes, not unlike
how some nodes make transaction data available to wallets via bloom filters or
the Electrum protocol. There's a whole variety of options available, and the
the data can be easily sharded to scale horizontally; the data is
self-validating allowing horizontal scaling without trust.

While miners and relay nodes don't need to be concerned about the initial
commitment proof, updating that proof is another matter. If a node aggressively
prunes old versions of the TXO MMR as it calculates pending TXO commitments, it
won't have the data available to update the TXO commitment proof to be against
the next block, when that block is found; the child nodes of the TXO MMR tip
are guaranteed to have changed, yet aggressive pruning would have discarded that
data.

Relay nodes could ignore this problem if they simply accept the fact that
they'll only be able to fully relay the transaction once, when it is initially
broadcast, and won't be able to provide mempool functionality after the initial
relay. Modulo high-latency mixnets, this is probably acceptable; the author has
previously argued that relay nodes don't need a mempool² at all.

For a miner though not having the data necessary to update the proofs as blocks
are found means potentially losing out on transactions fees. So how much extra
data is necessary to make this a non-issue?

Since the TXO MMR is insertion ordered, spending a non-archived txout can only
invalidate the upper nodes in of the archived txout's TXO MMR proof (if this
isn't clear, imagine a two-level scheme, with a per-block TXO MMRs, committed
by a master MMR for all blocks). The maximum number of relevant inner nodes
changed is log2(n) per block, so if there are n non-archival blocks between the
most recent TXO commitment and the pending TXO MMR tip, we have to store
log2(n)*n inner nodes - on the order of a few dozen MB even when n is a
(seemingly ridiculously high) year worth of blocks.

Archived txout spends on the other hand can invalidate TXO MMR proofs at any
level - consider the case of two adjacent txouts being spent. To guarantee
success requires storing full proofs. However, they're limited by the blocksize
limit, and additionally are expected to be relatively uncommon. For example, if
1% of 1MB blocks was archival spends, our hypothetical year long TXO commitment
delay is only a few hundred MB of data with low-IO-performance requirements.


## Security Model

Of course, a TXO commitment delay of a year sounds ridiculous. Even the slowest
imaginable computer isn't going to need more than a few blocks of TXO
commitment delay to keep up ~100% of the time, and there's no reason why we
can't have the UTXO archive delay be significantly longer than the TXO
commitment delay.

However, as with UTXO commitments, TXO commitments raise issues with Bitcoin's
security model by allowing relatively miners to profitably mine transactions
without bothering to validate prior history. At the extreme, if there was no
commitment delay at all at the cost of a bit of some extra network bandwidth
"full" nodes could operate and even mine blocks completely statelessly by
expecting all transactions to include "proof" that their inputs are unspent; a
TXO commitment proof for a commitment you haven't verified isn't a proof that a
transaction output is unspent, it's a proof that some miners claimed the txout
was unspent.

At one extreme, we could simply implement TXO commitments in a "virtual"
fashion, without miners actually including the TXO commitment digest in their
blocks at all. Full nodes would be forced to compute the commitment from
scratch, in the same way they are forced to compute the UTXO state, or total
work. Of course a full node operator who doesn't want to verify old history can
get a copy of the TXO state from a trusted source - no different from how you
could get a copy of the UTXO set from a trusted source.

A more pragmatic approach is to accept that people will do that anyway, and
instead assume that sufficiently old blocks are valid. But how old is
"sufficiently old"? First of all, if your full node implementation comes "from
the factory" with a reasonably up-to-date minimum accepted total-work
thresholdⁱ - in other words it won't accept a chain with less than that amount
of total work - it may be reasonable to assume any Sybil attacker with
sufficient hashing power to make a forked chain meeting that threshold with,
say, six months worth of blocks has enough hashing power to threaten the main
chain as well.

That leaves public attempts to falsify TXO commitments, done out in the open by
the majority of hashing power. In this circumstance the "assumed valid"
threshold determines how long the attack would have to go on before full nodes
start accepting the invalid chain, or at least, newly installed/recently reset
full nodes. The minimum age that we can "assume valid" is tradeoff between
political/social/technical concerns; we probably want at least a few weeks to
guarantee the defenders a chance to organise themselves.

With this in mind, a longer-than-technically-necessary TXO commitment delayʲ
may help ensure that full node software actually validates some minimum number
of blocks out-of-the-box, without taking shortcuts. However this can be
achieved in a wide variety of ways, such as the author's prev-block-proof
proposal³, fraud proofs, or even a PoW with an inner loop dependent on
blockchain data. Like UTXO commitments, TXO commitments are also potentially
very useful in reducing the need for SPV wallet software to trust third parties
providing them with transaction data.

i) Checkpoints that reject any chain without a specific block are a more
common, if uglier, way of achieving this protection.

j) A good homework problem is to figure out how the TXO commitment could be
designed such that the delay could be reduced in a soft-fork.


## Further Work

While we've shown that TXO commitments certainly could be implemented without
increasing peak IO bandwidth/block validation latency significantly with the
delayed commitment approach, we're far from being certain that they should be
implemented this way (or at all).

1) Can a TXO commitment scheme be optimized sufficiently to be used directly
without a commitment delay? Obviously it'd be preferable to avoid all the above
complexity entirely.

2) Is it possible to use a metric other than age, e.g. priority? While this
complicates the pruning logic, it could use the UTXO set space more
efficiently, especially if your goal is to prioritise bitcoin value-transfer
over other uses (though if "normal" wallets nearly never need to use TXO
commitments proofs to spend outputs, the infrastructure to actually do this may
rot).

3) Should UTXO archiving be based on a fixed size UTXO set, rather than an
age/priority/etc. threshold?

4) By fixing the problem (or possibly just "fixing" the problem) are we
encouraging/legitimising blockchain use-cases other than BTC value transfer?
Should we?

5) Instead of TXO commitment proofs counting towards the blocksize limit, can
we use a different miner fairness/decentralization metric/incentive? For
instance it might be reasonable for the TXO commitment proof size to be
discounted, or ignored entirely, if a proof-of-propagation scheme (e.g.
thinblocks) is used to ensure all miners have received the proof in advance.

6) How does this interact with fraud proofs? Obviously furthering dependency on
non-cryptographically-committed STXO/UTXO databases is incompatible with the
modularized validation approach to implementing fraud proofs.

A response to the GRS Shill cries

First of all, I think it is right to say that it wouldn’t be fair for the recent reddit to be entirely attributed to the recent 130% rise in GRS price – The price has gone a lot higher when SegWit was activated and a lot higher in the runup to the previous release announcement (22nd September) and was arguably at the ‘floor’ when it was discovered by us.
I’d like to give a little bit of a backstory on the recent discovery of GRS by a small group of people in a hope you realise this isn’t just shilling some shit-coin for a pump and dump. It was never our intention to come across as shilling and certainly not our intention to attract ‘pump and dump’ groups. We merely searched for SegWit-activated coins, and the main one that kept popping up was Groestlcoin, in posts that didn’t even mention Litecoin or Vertcoin. We thought that it was worth investigating further and decided to do some more research, and the more we found we more we realised that this was a genuine diamond amongst the rocks. 254th in market cap, first to activate SegWit, Lightning Network in full development, the list was endless – and seemingly nobody knew about it which was insanity.
In several places we saw that no marketing was done or being actively planned, and it was up to the community to market the coin if they wanted to whilst the 20+ developers keep cracking on to try and be the first to more developments.
We contacted the lead developer, ‘Jackielove4u’ and started a plan to try and market the coin, first by creating a Discord channel for discussions and then by trying to get their great features out to the world and aim for slow-and-steady growth.
In hindsight, a bit more finesse would have been better and the reddit posts got a little out-of-hand, if I didn’t know any better I would have seen GRS as a coin being shilled too on Reddit, and I have accused people of doing the same with Vertcoin in the past. So I thought I’d try to clear up some misconceptions and give one targeted response post to the cries of shilling and try to give the facts to the best of my knowledge, whilst trying to give an unbias opinion as much as I can based on my views and the views of the response that we’ve had.
PROS:
• Segwit Enabled Enabled first)
• Low-Power Mining – This is a selling point but people have said the power consumption is on-par with Vertcoin. I think the mining uses 2 rounds of Groestl algorithm hashing to make it more secure but is still very low on power consumption and hardware wear
• Lightning Network currently in development
• They have had an easy miner solution since 2015 – Although I’d be the first to admit it is a little clunky, but is openly on Git for improvements.
• 3 iOS wallets (Including a shared wallet), 11 android wallets (1x Secure BIP147, 1x Including sending GRS via SMS, 1x ability to use NFC tags as encryption keys), 11 blackberry wallets (Secure), 3 web wallets and 10 desktop wallets with varying features / designs – More to come on the differences soon.
• Over 80 electrum servers
• Working testnet
• Hosts their own block explorer
• Officially maintained by the Bitcoin Debian packaging team
• Ubuntu PPA available
• ASIC resistant, profitable CPU and GPU mining (And has an ARM miner apparently!) We’re just brushing the surface of the great tech that is being developed by the GRS developers.
CONS:
• Elephant in the room – The name. People have called it ugly, most don’t know how to pronounce it (It’s Groosel-coin). The developers are open to a rebrand pending a community vote in 2018.
• I’ve heard a few times ‘that logo looks like a cross between google and wordpress’. Again the logo is open to rebrand/redesign pending a vote (open for suggestions/examples!) but there is some significance in it. The ‘2’ in the logo is for the 2 rounds of Groestl algorithm hashing that is used.
• Obviously little or no marketing up until this point. Marketing is important (if not vital) for the success of a coin so we’re trying to spread some awareness.
• Lots of internet posts saying that it is a scam coin. From what I can see it seems to be because the coin has been ‘pumped-and-dumped’ a few times? By that logic, most coins are scam coins? The block reward dropped 6% a week when it was first launched specifically to prevent pump-and-dumps.
• Rumours of a pre-mine of 0.2% (240,000 coins) when it was first created. I haven’t gotten to the bottom of this to confirm or deny, but if it was true it seems to have been given as rewards for some early marketing (where those odd naked women pictures come from) and some early bounty rewards to get the ball rolling. No pre-mine is ideal but its personally something I can look over now if it IS true.
• Over 70% of the mined coins are owned by the top 100 addresses. Again, this is clearly an issue that many other coins also are facing (albeit some to a lesser extent). I can only guess that the more time that passes being a lesser-known coin, the greater risk that this becomes as the same miners mine for a longer period of time. Not sure if this matters much but it’s also worth noting that 24% of the mined coins appear to be on Bittrex currently.
TL:DR – Trying not to shill GRS, just trying to get the word out. Criticisms about the coin have been noted by the developers and they are very open to change and improvements suggested if they are the popular vote. I recommend that you research more into the coin, coin the discord on https://discord.gg/8VURndr and make a decision based on your own research whether you'd see something in, and like to support the coin.
Apologies for such a long post..

1088 Movable type in Song Dynasty China
1120 By the 1120s the central government officially stepped in and produced their own state-issued paper money (using woodblock printing)
1150 The Knights Templar issued bank notes to pilgrims. Pilgrims deposited their valuables with a local Templar preceptory before embarking, received a document indicating the value of their deposit, then used that document upon arrival in the Holy Land to retrieve their funds in an amount of treasure of equal value.
1200s-1300s During the 13th century bankers from north Italy, collectively known as Lombards, gradually replace the Jews in their traditional role as money-lenders to the rich and powerful. – Florence, Venice and Genoa - The Bardi and Peruzzi Families dominated banking in 14th century Florence, establishing branches in many other parts of Europe
1200 By the time Marco Polo visited China they’d move from coins to paper money, who introduced the concept to Europe. An inscription warned, "All counterfeiters will be decapitated." Before the use of paper, the Chinese used coins that were circular, with a rectangular hole in the middle. Several coins could be strung together on a rope. Merchants in China, if they became rich enough, found that their strings of coins were too heavy to carry around easily. To solve this problem, coins were often left with a trustworthy person, and the merchant was given a slip of paper recording how much money they had with that person. Marco Polo's account of paper money during the Yuan Dynasty is the subject of a chapter of his book, The Travels of Marco Polo, titled "How the Great Kaan Causeth the Bark of Trees, Made Into Something Like Paper, to Pass for Money All Over his Country."

1577 Newspaper in Korea
1586 The Babington Plot
1590 Cabinet Noir was established in France. Its mission was to open, read and reseal letters, and great expertise was developed in the restoration of broken seals. In the knowledge that mail was being opened, correspondents began to develop systems to encrypt and decrypt their letters. The breaking of these codes gave birth to modern systematic scientific code breaking.
1600s Promissory banknotes began in London
1600s By the early 17th century banking begins also to exist in its modern sense - as a commercial service for customers rather than kings. – Late 17th century we see cheques slowly gains acceptance
The total of the money left on deposit by a bank's customers is a large sum, only a fraction of which is usually required for withdrawals. A proportion of the rest can be lent out at interest, bringing profit to the bank. When the customers later come to realize this hidden value of their unused funds, the bank's profit becomes the difference between the rates of interest paid to depositors and demanded from debtors.
The transformation from moneylenders into private banks is a gradual one during the 17th and 18th centuries. In England it is achieved by various families of goldsmiths who early in the period accept money on deposit purely for safe-keeping. Then they begin to lend some of it out. Finally, by the 18th century, they make banking their business in place of their original craft as goldsmiths.

1666 Stockholms Banco, the predecessor to the Central Bank of Sweden issues the first paper money in Europe. Soon went bankrupt for printing too much money.
1667 He issues more notes than his bank can afford to redeem with silver and winds up in disgrace, facing a death penalty (commuted to imprisonment) for fraud.
1668 Bank of Sweden – today the 2nd oldest surviving bank
1694 First Central Bank established in the UK was the first bank to initiate the permanent issue of banknotes
Served as model for most modern central banks.
The modern banknote rests on the assumption that money is determined by a social and legal consensus. A gold coin's value is simply a reflection of the supply and demand mechanism of a society exchanging goods in a free market, as opposed to stemming from any intrinsic property of the metal. By the late 17th century, this new conceptual outlook helped to stimulate the issue of banknotes.
1700s Throughout the commercially energetic 18th century there are frequent further experiments with bank notes - deriving from a recognized need to expand the currency supply beyond the availability of precious metals.

1907 Banking Panic of 1907
The New York Stock Exchange dropped dramatically as everyone tried to get their money out of the banks at the same time across the nation. This banking panic spurred debate for banking reform. JP Morgan and others gathered to create an image of concern and stability in the face of the panic, which eventually led to the formation of the Federal Reserve. The founders of the Federal Reserve pretended like the bankers were opposed to the idea of its formation in order to mislead the public into believing that the Federal Reserve would help to regulate bankers when in fact it really gave even more power to private bankers, but in a less transparent way.

1910 Bankers Meet Secretly on Jekyll Island to Draft Federal Reserve Banking Legislation
Over the course of a week, some of the nation’s most powerful bankers met secretly off the coast of Georgia, drafting a proposal for a private Central Banking system.
1913 Federal Reserve Act Passed
Two days before Christmas, while many members of Congress were away on vacation, the Federal Reserve Act was passed, creating the Central banking system we have today, originally with gold backed Federal Reserve Notes. It was based on the Aldrich plan drafted on Jekyll Island and gave private bankers supreme authority over the economy. They are now able to create money out of nothing (and loan it out at interest), make decisions without government approval, and control the amount of money in circulation.
1913 Income tax established -16th Amendment Ratified
Taxes ensured that citizens would cover the payment of debt due to the Central Bank, the Federal Reserve, which was also created in 1913.The 16th Amendment stated: “The Congress shall have power to lay and collect taxes on incomes, from whatever source derived, without apportionment among the several States, and without regard to any census or enumeration.”

Frequently Asked Questions

NOTICE

This post is a temporary resting place for FAQs while we wait for the release of VertDocs.

What is Vertcoin?

Vertcoin is a digital peer to peer currency focused on decentralization and ASIC resistance. Vertcoin is aiming to be easily accessible to the everyday user without extensive technical knowledge. Vertcoin has started to lower the barrier of entry with lots of video guides and the development of the One Click Miner (OCM).

Why does ASIC Resistance Matter?

ASICs (Application Specific Integrated Circuits) are dedicated mining devices that can only mine one algorithm. Coins like Bitcoin and Litecoin both made GPU mining obsolete when SHA-256 and Scrypt ASICs were created.
ASIC Resistance and How it Makes Vertcoin Decentralized
Vertcoin believes that ASIC resistance goes hand in hand with decentralization.
ASICs are made by companies like Bitmain and almost all the original sellers of ASICs sell on a preorder basis. When pre ordering an ASIC you are buying from a limited batch that the ASIC company has produced. Often times the batch will not be fully filled and the ASIC company will often have left over ASICs. When the ASIC company has left over ASICs they will put them to work mining. Soon enough the ASIC company will have a very large amount of unsold ASICs that are mining and slowly the ASIC company starts to own a large part of the network’s hashrate. When an ASIC company(s) starts to own a large majority of the hashrate the network can become very centralized after a while.
Having your network consist of a few large companies can be very dangerous as they could eventually get 51% hashing power and 51% attack your network, destabilizing the network. When your network is made out of a lot of smaller miners, like Vertcoin, it is much harder for your network to be 51% attacked, therefore increasing network security. By having centralized hashing power your coin effectively centralizing the network as the centralized hashing power can deny transactions and stop any activity they don’t want.

What Ways is Vertcoin Superior to Litecoin and Bitcoin?

Network Difficulty Adjustments with Kimoto Gravity Well
Vertcoin uses a difficulty adjustment called Kimoto Gravity Well which adjusts the difficulty every block, whereas Bitcoin and Litecoin’s difficulty changes every 2016 blocks. By adjusting the difficulty every block Vertcoin’s block time can stay consistent by adjusting for the fluctuation in network hash rate from hash rate renting and part time miners. If a large miner switches off Bitcoin or Litecoin mining the network could be slowed to a crawl until 2016 blocks are mined and the difficulty can change to adjust for the new network hash rate. We observed this happen to Bitcoin when Bitcoin Cash became more profitable than Bitcoin and Bitcoin’s network hash rate saw a steep fall off, slowing the network to a crawl. If this was to happen with Vertcoin the difficulty would adjust after 1 block was mined, allowing Vertcoin to always be profitable to mine.
Anyone can Meaningfully help Verify Transactions
In Proof-of-Work crypto currencies miners help secure the blockchain and get rewarded with the block reward. In ASIC mineable coins like Bitcoin and Litecoin you can’t meaningfully verify transactions unless you pay 1000-2000$ for a ASIC miner. When you mine with a CPU or GPU in a ASIC mineable coin you make no meaningful impact on the network. It is like trying to break concrete with a shovel while everyone else has a jackhammer.
Simple Upgrades Aren’t Held back by 1-2 Large Miners
In ASIC market people buy ASICs in batches in a preorder. With Bitcoin ASICs there is not enough demand for ASICs so the batch often doesn’t get sold out so now the manufacturer has spare ASICs. Now that the manufacturer has spare ASICs they will often start mining with them and eventually the ASIC company has one of the highest hash rates. If the ASIC company doesn’t want a certain upgrade to go through, for example SegWit, they can vote with their hash rate to hold back the upgrade forever or at least until people who want SegWit get more hash rate.
You Have a Say in Protocol Rules and Consensus
In Bitcoin you are a passive observer because you can only issue transactions and you have no part in the process after that. In Vertcoin you can be apart of the process for deciding the ordering of transactions and deciding what transactions get into blocks.
Block Rewards and Transaction Fees are Distributed Evenly
In Bitcoin and Litecoin the block rewards and transaction fees are often given to the large miners in China due to mining centralization created by ASICs. Vertcoin distributes its mining rewards to people all around the world thanks to the mining decentralization.

When will Atomic Swaps Be Ready?

Atomic Swaps can be done in two flavors: On-chain and Off-chain (via Lightning Network). On-chain swaps were actually done already using Blocknet, you can see it in use on Youtube. We're looking into doing it again using Interledger.
However our main focus is to do off-chain Atomic Swaps using Lightning Network technology. Because it has the same benefits as Lightning transactions: No network fees and instant transactions.
For off-chain swaps we need Lightning Network to be fully operational. It's difficult to give an ETA on that since we aren't the ones developing it. U/gertjaap posted a video on the current state of the Lightning Network for Vertcoin a while ago, which you can see here.
This was actually the "bleeding edge" of Lightning Network at the time. was able to use it on VTC's main net, meaning that our blockchain is ready for the good stuff. As you can see however, it can't yet be considered production ready (most users would want a little better UX than a command line app).
Now off-chain Atomic Swaps is a technique based on the same principles as Lightning Network, but adds an extra complexity for it being across chains. So it's basically the same as a "multi hop" Lightning payment, which is not yet built by any of the implementations. They're still working hard on making the single-hop payments robust. So in order for AS to be possible, LN has to be fully operational.
A timeline cannot be given at this time, because frankly we don't know. The implementation of Lightning Network we feel has the most potential is LIT, because it supports multiple currencies in its protocol (where LND is bitcoin-only at the time and requires significant work to support other currencies, which is an essential part of being able to work across multiple blockchains).
LIT is open source and there's nothing secretive about its progress, you can see the development on Github. We even have our lead dev James Lovejoy (u/jamesl22) close to the action and contributing to it where possible (and our team as well through testing it on the Vertcoin chain).
So we're not developing LN or AS ourselves, we're just ready with our blockchain technology whenever it becomes available.
If we have any real progress that has some substance, you can expect us to let the world know. We're not interested in fluffy marketing - we post something when we achieve real progress. And we are not keeping that secret.

How do I Choose the Right Vertcoin Wallet?

Deciding what Vertcoin wallet you should choose can be a difficult process. You can choose between three different wallets: Core, Electrum and Paper. Once you decide you can use the "How to Setup Your Vertcoin Wallets" video guide to assist you.

Core

The Core wallet is the wallet that most people should use. It will store the entire blockchain (~2GB) on your computer. The Core wallet is the only wallet that fully supports P2Pool mining. You will also have to use the Core wallet if you plan to run a P2Pool node or any Vertcoin related server.

Electrum

The Electrum wallet is a light wallet for Vertcoin. You do not have to download the blockchain on your computer, but you will still have your own private keys on your computer. This is recommended for people who don't need to store Vertcoins for very long and just need a quick but secure place to store them.

Paper

The Paper wallet is as the name implies, a physical paper wallet. When generating a paper wallet you will get a pdf that will need to print out. A paper wallet is normally used for long term storage since it is the safest way to store Vertcoins. A paper wallet can also be called "cold storage." Cold storage references the storage of your coins offline, preventing you from getting hacked over the internet.

Ledger Nano S

The Ledger Nano S is a hardware wallet designed by Ledger. A hardware wallet is similar to a paper wallet since it is normally used for cold storage. The hardware wallet is on par with the security of a paper wallet while being easy to use and setup. Note: You should never mine directly to a Ledger hardware wallet.

How do I start mining Vertcoin?

We have many guides available for you to use depending on your computer specifications.
Nvidia GPUs on Windows
Nvidia GPUs on Linux
AMD GPUs on Windows WARNING: Very unprofitable, AMD optimized miner is coming very soon.

Where can I get the One Click Miner (OCM)

You can get the latest version of the One Click Miner in the Vertcoin Discord. The download is pinned to the top of the #oneclick channel.

What do all the Numbers Mean on P2Pool’s Web Interface

I've seen a lot of confusion from new miners on public p2pool nodes, so here's a primer for the most common static node page style, for first time miners: https://imgur.com/K48GmMw

Active Miners on this Node

Address - This is the list of addresses currently mining on this node. If your address does not show up here, you are not mining on this node.
Hashrate
This is a snapshot of your hashrate as seen by the node. It will fluctuate up to 15% from the hashrate you are seeing on your mining software, but will average out to match the output in your mining software.
Rejected Hashrate
This is the amount of your hashing contribution that is rejected, both in hashrate and as a percentage of your total contribution. Running your own p2pool node minimizes this number. Mining on a node that is geographically close to reduce lag also minimizes this number. Ideally you would like it to be less than 1%, but most people seem happy keeping it under 3%.
Share Difficulty
This speaks for itself, it is the difficulty of the share being currently worked on. Bigger numbers are more difficult.
Time to Share
This is how long you need to mine before you will receive any payouts, or any "predicted payout." The lower your hashrate, the higher your time to share.
Predicted Payout
This is the reward you would receive if a block was found by p2pool right now. If it reads "no shares yet" then you have not yet been mining the requisite amount of time as seen in the previous "time to share" column.

Status

Network Hashrate
This is the total hashrate of all the miners mining vertcoin everywhere, regardless of where or how.
Global Pool Hashrate
This is the total hashrate of all the miners mining vertcoin on this p2pool network, be it the first network or the second network.
Local Pool Hashrate
This is the total hashrate of all the miners mining Vertcoin on this node.
Current Block Value
This is the reward that will be given for mining the current block. The base mining reward is currently 50 VTC per block, so any small decimal over that amount is transaction fees being paid by people using the network.
Network Block Difficulty
This is the difficulty of the block being mined. The higher the number, the higher the difficulty. This number rises as the "Network Hashrate" rises, so that blocks will always be found every 2.5 minutes. Inversely, this number falls when the "Network Hashrate" lowers as well.
Expected Time to Block
This is a guess at how much time will elapse between blocks being found by this p2pool network. This guess is accurate on average, but very inaccurate in the short term. Since you only receive a payout when the network finds a block, you can think of this as "Estimated Time to Payout."

Why is P2Pool Recommended Over Traditional Pools?

Decentralisation

P2Pool is peer to peer allowing a decentralized pool mining system. There are many nodes setup around the world that connect to each other too mine together. Many other coins have 1 very large pool that many miners connect to and sometimes the largest pool can have 51% or more of the network hash rate which makes the network vulnerable to a 51% attack. If P2Pool is the largest network then that prevents the Vertcoin network to be susceptible to a 51% attack as P2Pool is decentralized.

PPLNS Payout System

P2Pool uses a PPLNS (Pay Per Last N Shares) payout system which awards miners more the longer they mine, sort of like a loyalty system. A drawback to this system is that part time miners that aren't 24/7 won't be able to earn that much.

2 Networks

While Network 1 is catered towards 24/7 miners and people who have dedicated mining rigs, Vertcoin has a second P2Pool network where part time miners and miners under 100 MH/s can go to mine.

Mines Directly to Your Wallet

P2Pool mines directly to your wallet and cuts out the middleman. This reduces the likely hood that the pool will run away with your coins.

No Downtime

Since P2Pool is decentralized and has different nodes for you to choose from there will be no downtime because the P2Pool network does not die if one node goes down. You can setup a backup server in your miner so that you will have no downtime when mining.

Anonymity and Security

When using P2Pool you use a wallet address making your real identity anonymous, you are simply known by a random 34 letter string. Along with using a wallet address instead of a username there is no password involved P2Pool preventing the possibility of cracking your pool account (If you were on a traditional pool,) and stealing all your coins.

How do I Find a Nearby P2Pool Node

You can find the public p2pool nodes the the P2Pool Node Scanners. If you want to find a network 1 node go here. If you want to find a network 2 node go here.

How do I setup a P2Pool Node?

Linux P2Pool Setup
Windows P2Pool Setup (Text)
Windows P2Pool Setup (Video) This guide setups a network 2 node. When downloading Python download the 32bit version, not the 64bit. Downloading the 64bit version causes problems with the twisted install.
How do I setup a change my node to network 1 or network 2?
In the P2Pool startup script when you type the --network flag add vertcoin1 for network 1 and vertcoin2 for network 2 right after.

How do I Buy Vertcoin?

You can see a video guide on Youtube, "How to Buy Vertcoin with Fiat Using Bittrex and Coinbase"

How can I get help with "X problem?"

The quickest way for you to get help is for you to join the Vertcoin Discord Group. We almost always have knowledgable Vertans, whether that be developers or experienced Vertans, online to help you with whatever problems you may have.

How can I donate to the Developers?

You can donate to the dev fund at https://vertcoin.org/donate/. You can select what you want your funds to go to by donating to the corresponding address. You can also see how much funding is required and how much we have donated.

Where can I see what exchanges Vertcoin is on?

You can see what exchanges Vertcoin is listed on at CoinMarketCap. You can see what exchanges Vertcoin has applied to be on at this google docs spreadsheet.

Where can I see Vertcoin's Roadmap?

The Vertcoin developers currently have a trello board where you can see the goals and what the status of said goal is. You can also vote on what you want the Vertcoin developers to focus on next.

What is the Status of the AMD Optimized Miner?

The AMD Optimized Miner internal beta is aiming to be ready by the end of September. The AMD Optimized Miner is currently being developed by @turekaj on the Vertcoin Discord. He currently does not have a Reddit account and Discord is the only way you can contact him.

What Does Halving Mean?

Halving means that the block reward for miners will be split in half. Halving happens around every 4 years for Vertcoin or 840,000 blocks. This means around December miners will only receive 25 VTC per block instead of the current 50 VTC per block.

I would like to address FUD regarding colored coins and ChromaWallet

I am the lead developer of ChromaWallet. I've noticed that people who are presumably proponents of competing projects post comments which are dismissive and hostile towards colored coins and ChromaWallet. In many cases these posts are based on information which is only half-true, or sometimes not true at all. I'd like to address this unfair criticism here instead of chasing each individual comment.
FUD: Colored coins are irrelevant, because we already have Counterparty. (Also, Mastercoin, Ethereum, BitShares, NXT and so on.)
This would be true if Counterparty could do everything which colored coins can, but that's just not true. Counterparty uses a fundamentally different approach, which means that some things which can be implemented on top of colored coins are impossible with Counterparty, particularly:
Fast trading. First of all, let's consider how it is done in Counterparty: orders are submitted as separate transactions, which can be included into blockchain in arbitrary order. That means that you cannot reliably cancel an order or change price until your original transaction gets into a Bitcoin block, which takes on average 10 minutes. Thus you cannot change price very often (don't forget that you pay a transaction fee for each new order).
Also, you know whether your order was matched only after it is in a block, which, again, takes something on scale of 10 minutes. If you want to buy an asset for Bitcoin, it's even worse; first you need to find a matching order, and then you need to do a Bitcoin payment. In the best case, this requires two Bitcoin blocks, thus average time is 20 minutes. In the worst case, if your Bitcoin transaction is confirmed too late, you will lose your Bitcoins without getting that asset. On the sellers end, you might wait for several hours, but payment won't arrive.
On the bright side, Coutnerparty "dex" requires only Bitcoin network/blockchain. So it is highly available. But slow. Potentially problematic when you use Bitcoin as a currency.
On the other hand, in case with colored coins, trading protocol can be implemented as a separate protocol built on top of core coloring protocol and atomic transactions. As such, it is very flexible, you can choose trade-offs relevant to your particular applications.
Let's consider a specific protocol, p2ptrade (which was first released, as a working proof-of-concept, in January 2013, as a part of ArmoryX):
ArmoryX is dead now, but the similar thing is implemented in ChromaWallet, so you can see yourself that it takes around 5 seconds to complete a trade, not 10 minutes, and not 1 hour.
Micropayment channels, transaction aggregation: Paying a standard Bitcoin fee for each payment is not cool, for many applications that's too much. With colored coins we can use almost all standard Bitcoin features, which can make payments much cheaper and/or faster. I don't think that can work with Counterparty.
SPV: With colored coins, we can implement a "thin" client which will be able to independently verify payments without downloading the whole blockchain. In fact, that's how ChromaWallet works now, it's very similar to Electrum. We can also implement a mobile and in-browser clients which do not need to trust the server.
I could go on, but I hope it's obvious that Counterparty isn't the best at everything, and there might be some room for colored coins. (To be fair, there are certain things which Counterparty can do, but colored coins can't: Counterparty can resolve CFDs and bets based on asset price automatically.)
As for other projects (NXT, Ethereum, BitShares...), they have numerous advantages, but still aren't completely "dominating" over colored coins: I believe the fact that colored coins can provide complete integration with Bitcoin is a significant feature which justifies its existence.
FUD: Development is slow.
Answer: This is partially true.
First of all, few words about ChromaWallet. It started as an open source project supported by donations, which allowed us to to release an alpha version. But then, after donations dwindled, development pace have drastically slowed down. But recently we have organized a for-profit company which will continue to develop ChromaWallet, hopefully at much faster pace. (The wallet will remain open source, of course; we're going to monetize services which will be useful to wallet's users.) One example of what it have already done is coloredcoinjs-lib, a JS library for colored coins. It is something like 90% complete after one month of development.
Then there are several other projects like CoinPrism and Iridis, which are making good progress.
So, yeah, it could be faster, but it is hardly a reason to dismiss colored coins.
FUD: Development efforts are fragmented.
Answer: Well, they are: there are several different implementations. I don't see it as a bad thing, though: there are, probably, dozens of different potential applications of colored coins. We don't need same piece of software doing everything.
I see colored coins as a toolkit for implementing different kinds of applications on top of Bitcoin blockchain, not as a particular standard.
FUD: ChromaWallet isn't working.
I'm fairly certain it's working. It has some deficiencies (like some error messages are displayed in console instead of being shown in GUI), but they are relatively minor. What's important, you can send and receive payments, even p2ptrade is working. Still, it is a beta. We would rather take more time for testing and fixing, thus we ask people to avoid using it for anything of value. Better be safe than sorry, you know.
FUD: ChromaWallet requires complex installation process.
This was true for alpha release which was in December, but not for more recent beta release. Just download, unpack and it works. We're working on web and mobile versions now...
FUD: p2ptrade is not decentralized, there is no colored coins decentralized exchange!
Well, it depends on how you define a "decentralized exchange", of course.
p2ptrade, as implemented in ArmoryX and ChromaWallet, relies on a communication channel implemented as an HTTP service. The thing is, anybody can run his own service. So it is definitely decentralized, as it allows two (or more) parties to trade without relying on a central service.
Also, Iridis implements a similar thing which uses BitMessage for communication.

Tacotime mentioned a hard fork proposal to never let the block reward drop below 1 coin:
Code: if (blockReward < 1){ blockReward = 1; }
I assume this is merely delaying the problem, however. I proposed a fixed annual debasement (say 2%) with a tx fee cap of like 0.001% of the current block reward (or whatever sounds reasonable). That way we still get the spam protection without worrying about fee escalation down the road."

-2059: I was skeptical of this conspiracy theory at first but after thinking about the numbers and looking back at the code again, I'm starting to believe it.
These are not deep optimizations, just cleaning up the code to work as intended.
At 100 H/s, with 500k iterations, 70 cycles per L3 memory access, we're now at 3.5 GHz which is reasonably close. So the algorithm is finally memory-bound, as it was originally intended to be. But as delivered by the bytecode developers not even close.
I know this is going to sound like tooting our own horn but this is another example of the kind of dirty tricks you can expect from the 80% premine crowd and the good work being done in the name of the community by the Monero developers.
Assuming they had the reasonable, and not deoptimized, implementation of the algorithm as designed all along (which is likely), the alleged "two year history" of bytecoin was mined on 4-8 PCs. It's really one of the shadiest and sleaziest premines scams yet, though this shouldn't be surprising because in every type of scam, the scams always get sneakier and more deceptive over time (the simple ones no longer work)."

-3283: "Most of the previous "CPU only" coins are really scams and the developers already have GPU miner or know how to write one. There are a very few exceptions, almost certainly including this one.
I don't expect a really dominant GPU miner any time soon, maybe ever. GPUs are just computers though, so it is certainly possible to mine this on a GPU, and there probably will be a some GPU miner, but won't be so much faster as to put small scale CPU miners out of business (probably -- absent some unknown algorithmic flaw).
Everyone focuses on botnets because it has been so long since regular users were able to effectively mine a coin (due to every coin rapidly going high end GPU and ASIC) that the idea that "users" could vastly outnumber "miners" (botnet or otherwise) isn't even on the radar.
The vision here is a wallet that asks you when you want to install: "Do you want to devote some of you CPU power to help secure the network. You will be eligible to receive free coins as a reward (recommended) [check box]." Get millions of users doing that and it will drive down the value of mining to where neither botnets nor professional/industrial miners will bother, and Satoshi's original vision of a true p2p currency will be realized.
That's what cryptonote wants to accomplish with this whole "egalitarian mining" concept. Whether it succeeds I don't know but we should give it a chance. Those cryptonote guys seem pretty smart. They've probably thought this through better than any of us have."

-3571: "Tacotime wanted the thread name and OP to use the word privacy instead of anonymity, but I made the change for marketing reasons. Other coins do use the word anonymous improperly, so we too have to play the marketing game. Most users will not bother looking at details to see which actually has more privacy; they'll assume anonymity > privacy. In a world with finite population, there's no such thing as anonymity. You're always "1 of N" possible participants.
Zero knowledge gives N -> everyone using the currency, ring signatures give N -> your choice, and CoinJoin gives N -> people who happen to be spending around the same amount of money as you at around the same time. This is actually the critical weakness of CoinJoin: the anonymity set is small and it's fairly susceptible to blockchain analysis. Its main advantage is that you can stick to Bitcoin without hard forking.
Another calculated marketing decision: I made most of the OP about ring signatures. In reality, stealth addressing (i.e. one-time public keys) already provides you with 90% of the privacy you need. Ring signatures are more of a trump card that cannot be broken. But Bitcoin already has manual stealth addressing so the distinguishing technological factor in CryptoNote is the use of ring signatures.
This is why I think having a coin based on CoinJoin is silly: Bitcoin already has some privacy if you care enough. A separate currency needs to go way beyond mediocre privacy improvements and provide true indistinguishably. This is true thanks to ring signatures: you can never break the 1/N probability of guessing correctly. There's no additional circumstantial evidence like with CoinJoin (save for IP addresses, but that's a problem independent of cryptocurrencies)."

  • Crippled miner Gave unfair advantage to those brave enough to risk money and time to optimize and mine Monero.
  • Fast curve emission non-bitcoin-like curve as initially advertised and as it was widely accepted as suitable
Though we have to say two things to support current Monero community and devs:
  • The crippled miner was coded either by Bytecoin or CryptoNote, and 100% solved within a month by Monero community
  • The fast curve emission was a TFT miscalculation. He forgot to consider that as he was halving the block target he was unintentionally doubling the emission rate.
