Subject: Re: [bitcoin-dev] Bitcoin XT 0.11A
Precedence: list

Hello Jorge, Eric,

With all this noise on the -dev mail list I had to implement application
level filters so I can treat with priority posts from certain people,
you are on that list. While I agree with your arguments, I think it is
_very_ important to highlight some things. I am neither for the
blocksize increase neither against it, because plain and simple I don't
have enough arguments to take some definitive decision on this topic.
What I am angry about is spreading FUD that a fork could kill Bitcoin
and what we are experiencing now is somehow terrible.

1. Bitcoin XT is not necessarily an attack over Bitcoin and will not
split it into 2 different coins. It is the result of an open source free
system which lacks centralization. It is just at early stage, it could
have thousands for forks (or fork attempts) during its life.

2. We have no proof that Mike Hearn and Gavin Andresen are trying to do
something bad to Bitcoin. So far everything they have done is (or should
be) allowed. They have forked an open source software and implemented a
voting system for a consensus rule change - doesn't sound like they are
committing a crime here (either legally or morally). If they are
qualified enough to maintain the software, or if the decision is
technically correct or not is another story, and it should only matter
to whoever uses / wants to use -XT.

3. If Bitcoin's value can be decreased (or Bitcoin as a project killed)
just by 2 people forking the software and submitting a consensus rule to
a vote, it means Bitcoin is dead already and it should be worthless! We
can't go around and panic every time somebody forks Bitcoin and tries to
change something - this should be allowed by the nature of its license.
If tomorrow 5 more people fork 5 different software implementing the
bitcoin protocol and submit 5 different new consensus rules to a vote,
then what? We should all sell so the price will drop to 1 cent, because
it is somehow not good enough, not stable enough?

I can fork tomorrow Bitcoin Core to a Bitcoin-XYZ software which at some
block in the future spends all the longest dusted coins to me, out of
which I give away 50% to the miners (so the hashing power will have
incentive to use my fork).

Can they do it? YES
Will they do it? NO
Should the world care about this? NO

It's as simple as that. We cannot continue to panic that "Bitcoin as a
project" is at threat because somebody forked it.

4. By having a software fork and consensus rule submitted to vote we
actually prove how open Bitcoin is, and how there is lack of control
over it from all parties (developers, miners, engineers on the mail
list). This is reason to increase Bitcoin's value! It is a feature, not
a flaw!


It's very important for everyone in the ecosystem to understand:

- yes, Bitcoin is open source, even you can fork it tomorrow if you want
and you think enough users might follow you.

- no, it's not a requirement for 100% of the nodes in the network to be
running Core, or -XT or other implementation. The more we have, the better.

- yes, there is absolutely no authority in Bitcoin - this is what lead
to this dispute in the first place. This is the truly decentralized
nature of the software, not important if we have 10.000 full nodes or
1000 full nodes.

- no, Bitcoin won't split / die or whatever because of this fork.
Regardless what it happens, if XT will reach the threshold or not,
Bitcoin will go on just because it has some unique advantages and has no
competitor from some points of view.

- Bitcoin by its design has many many advantages, but also the
limitation that it relies on majority being honest / doing the right
thing! This is just the way it is, and the benefits it is offering
heavily win over this fundamental limitation.
