We are talking about money here. Decisions in this project are
not made based on 'merit', they are made based on ROI. If killing
the project is more profitable, many of the actors involved are
obligated to their shareholders to attempt to kill the project.
Or maybe in this case, they might be obligated to their investors
to attempt to try to run all the competing miners out of business
and acquire a majority stake in the hashpower.
If Merit were actually important, I would hope we would be
talking about a way to finance development in a way that provides
real financial incentives for merit, rather than what appear to
be some perverse incentives that seem to be rewarding short-term
traders, conflict, and further consolidation of mining and
exchanges.
The other problem with merit is there are just about as many ideas
about what has merit as there are people judging the merit of the
project.
For instance, I think demurrage and increasing the money supply are
ideas with more merit, but those ideas are not profitable to existing
bitcoin investors, and thus are not seriously discussed.

C'mon people.
Anyone remember when git didn't even exist and all we had was CVS,
subversion, and BitKeeper?
Get me a couple of motivated grad students who know Python and we can
turn a combination of Mercurial, BitTorrent, and pynode into a distributed,
leaderless, decentralized version control system that can let users
create a crypto key, anonymously propose BIPs, and then get paid in
crypto for the best commits.
Who else would contribute to a crowdfunding effort to do such at thing?

I think many of us who think about human - computer interactions see the
need for a well defined process to roll back unexpected behavior in a computer
system. My 2014 era proposal is https://bitbucket.org/tmagik/catoshi/issues/24
The fundamental assumption around cryptocoins is you have a secret (private
key) known only by you. Currently in bitcoin if that assumption changes, the
response is blame the user. 'Incompetence, etc, etc'
This is bad business. For any cryptocurrency to really get mass market, we
need to provide our users with key revocation, to be used when the assumption
about being the only holder of a secret is broken.
I think there's a hardfork-worthy choice here:
1) implement reversal/revocation as an add-on feature
2) implement reversal/revocation as a fundamental that every address gets.
Ethereum made a quick hardfork choice to reverse a *single* instance of
unexpected behavior, and looks a lot like a bank bailout. We have the chance
to learn from this mistake, and, apparently, make a lot of money trading
on both sides of the hardfork.

If a proprietary stack has problems with replace-by-fee then it's probably
succeptible to malicious attack because an attacker could just broadcast
one transaction to the network and then replace it when they are able to

What I would really like is a frontend and/or integration to Git/Mercurial that
uses Bitcoin transactions *as* the signature, which has the nice side effect of
providing timestamps backed by the full faith and credit of a billion dollar
blockchain. So what is the best way for me to stick both a git *and* a
mercurial identity hash into a bitcoin transaction? (which leads to point 2
below)

I'm not interested in volunteer, I'm interested in getting paid, and the
best way I believe I can accomplish that is use *my* bitcoin address in a
signature-transaction of the code I've reviewed.
What is the advantage of PGP? Far more people have ECDSA public-private
keys than PGP keys.

This is why I clone git to mercurial, which is generally designed around the
assumption that history is immutable. You can't rewrite blockchain history,
and we should not be re-writing (rebasing) commit history either.
The problem with github is it's too tempting to look at the *web page*, which
is NOT pgp-signed, and hit the 'approve' button when you might have someone
in the middle approving an unsigned changeset because you're in a hurry to
get the latest new critical OpenSSL 0day security patch build released.
We need multiple redundant 'master' repositories run by different people in
different jurisdictions that get updated on different schedules, and have all
of these people pay attention to operational security, and not just outsource
it all to github because it's convenient.
There's no reason to *stop* using github, cause it *is* easy... but you want
to have multiple review of *the actual code*, not just signatures and see
if the changes really do make sense.

I guess I should update it more than every 6 months and then the updates
won't take so long. It would also go a lot faster if I had a couple of
dedicated servers, but that won't happen until I sell someone a support
contract for crypto-commodities trading. I figure a bitcoin a month should
support the hardware, 24x7 monitoring, and maybe a couple of full nodes
running on the servers as well.
And to pick up from another comment on this thread if you don't understand
some of the differences between git and mercurial, or how to set up servers
that pull from git and mirror to mercurial, you will have a lot harder time
tracking down and removing malicous code that could get injected if someone
gets root on a Github server.
It is also a very usefull excercise in distributed systems design to
understand how distributed revision control systems in theory converge to a
coherent global state, and what is similiar or different to Bitcoin's
global consensus model of what the balance of every bitcoin address is.

If a project cannot be organized enough to run its own hosting/web presense/
counterintelligence/security that starts with installing an OS and patching
kernels, then it is really not wise for me to trust my financial future to
software written by such a group.
There is a great deal of 'work' that is really quite pointless, particularly
in regards to claims I see about security that are irrelevant unless you
have the understanding that comes from operating and running your own
servers.
This includes running DDOS protection, so no cloudflare.
If bitcoin wants to become irrelevant, then by all means, continue to
depend on github and all the unknown attack surface it exposes.
Those of us that do run our own servers will migrate to higher quality
alternatives.

As an end-user of Bitcoin, the whole possible value of a set of mathematical
rules has become completely trashed by the imprecise and unpredictable behavior
of buyers and sellers.
If the rules are not responsive to real human needs, bitcoin is worthless
as a long-term store of value because **my idea of value** changes over time.
This implies, in my mind, an absolutely requirement to attempt to gather
some useful signal from the human political noise.
How do you determine what that signal is, so you can **change the rules**
and the mathematics so it makes more sense?
You've got to deal with politics, one way or another.

Using a bitcoin address as a persistent identity key is the first real-world
use of Bitcoin that I can imagine will make it a 'killer app' that everyone
and their grandma will want to use.
If you think 'certificates' are a good solution, then there is some way in
which we have dramatically divergent goals.
I like distributed, decentralized systems in which anyone can download the
code and be free to participate in the things they want to securely and
reliably.
As soon as I hear 'certificate', I see a system in which one must pay at toll
to speak, and which puts the listeners at risk because a certificate issuer

I foresee 2^128 being brute forceable in 20-25 years. See below.

So I assume this image is using the Landauer principle for minimum
energy ( http://en.wikipedia.org/wiki/Landauer%27s_principle ), however
it is unknown (to me at least) if a reversible computing ecdsa forcing
algorithm could be implemented. (this may or may not be a quantum
computing device)
Let's suppose for a moment you could, and get a million times better
than the Landauer pinciple limit of 2.85 zJ per bit, so we have total
energy to cycle through 128 bits of address space of:
units "2**128 * 2.85zJ / 1e6" "megawatt*hours"
* 269.39021
An attacker with a sub-Landauer limit/1e6 cracker would need a lot of
silicon area, and a couple of hours energy from a large wind farm, and
could siphon that energy out in a rural area without anyone noticing
anything other than a few shipping containers and that the wind turbines
are running more on windy days.
If we go back to just Landauer limit, and assume a 10MW system that
runs 24x7 (much like the NCSA Blue Waters Cray machine), we need:
(please check my math, or point out any stupid assumptions I've made)
units "2**128 * 2.85zJ / 10 megawatts" " years"
* 3073.1914
Or 3000 years. Well that still sounds pretty safe. How about 250MW?
units "2**128 * 2.85zJ / 250 megawatts" " years"
* 122.92766
Now I'm starting to get worried, because when I started computing, it
was on an 8-bit CPU that was measured in thousand operations-per-second.
In 1996 the largest supercomputer in the world was ASCII Red, with an
amazing 1 trillion floating-point operations per second. This morning
I have a 1-2 Teraflop water-cooled graphics processor sitting next to
me warming the room.
I expect in 5-10 years we'll have silicon with 256 bit registers that
may be able to do thousands or millions of ECDSA calculations per
second per computation unit.
So if you stop hearing from me here, it's because I found a better
mailing list, or a got a contract to develop and ECDSA cracker, in
which case you probably won't hear from me again until I have a talk
at DEFCON showing it off.

Using the same keys across different altcoins seems like an exceedingly bad opsec
practice. Cointype is critical, as well as having a predictable and deterministic
mapping of alt coins to Cointype.
What should I be using for Catcoin, for instance? the CAT symbol all the
exchanges use, or do we set up a 'registry', or some other mechanism?
I'd venture to guess the altcoin market is, or soon will be larger in US
dollar value trade volume than Bitcoin, so *some* of us are quite bothered
by the wailing and gnashing of teeth that occurs on this list at mere thought
of such heresy.

I think is actually a major fundamental disagreement, and opinions
tend to correlate strongly with salary considerations.

I think you and I both know there is WAAYY to much MONEY to be taken

I'd rather have Peter Todd calling some developers idiots on the

calling 'end-users' stupid for believing MtGox. Hell, I was one
of these idiots that fell for a marketing scam by a company that
had a good story.
But here is the damn point. The Excecutive who was whining about
how his devs won't show up should probably consider hiring people
who make VOCAL points on the mailing list. Or maybe he should
consider that his developers might know his business model is
shit and if they DID say something, it would be CLEAR to the
world that only an idiot would use their companies services, and
kill the company.
Would you rather hear of vulnerabilities and scaling limits on
bitcoin-development, or would you rather hear about them by a
chorus of "They got hacked, their code must suck", but AFTER
the fact.
It seems to be an unfortunate fact of life that sleazy people
take a shitload of money from nice people. Moderate Peter and
I into oblivion at your own risk. Wouldn't you rather have us
pointing out obvious flaws than ignoring shit?

When I can pick up a miner at Best Buy and pay it off in 9 months I'll
agree with you that bitcoin *might* be decentralized. Maybe there's a
chance this *will* happen eventually, but right now we have a couple of
mining cartels that control most of the hashrate.
There are plenty of interesting alt-hash-chains for which mass produced,
general purpose (or gpgpu-purpose) hardware exists and is in high volume
mass production.

I've spend some time looking at the Datacoin code, and I've come to the
conclusion the next copycatcoin I release will have an explicit 'data'
field with something like 169 bytes (a bakers dozen squared), which will
add 1 byte to each transaction if unused, and provide a small, but usable
data field for proof of publication. As a new coin, I can also do a
hardfork that increases the data size limit much easier if there is a
compelling reason to make it bigger.
I think this will prove to be a much more reliable infrastructure for
proof of publication than various hacks to overcome 40 byte limits with
Bitcoin.
I am disclosing this here so the bitcoin 1% has plenty of time to evaluate
the market risk they face from the 40 byte limit, and put some pressure to
implement some of the alternatives Todd proposes.

and then plan on rolling back to mBTC when the price crashes from altcoin

I think the ship of hand-wavy, data-free logic sailed with
'money supply == 21 million', so why not enjoy the ride? If we care about
real people and real use cases, then let's talk about indexing the money
supply to some blockchain-observable value and add demurrage instead of
of bikeshedding the color of the latest coat of paint.

I'm surprised every time I pull up to a gas pump and the price is 3.249999
per gallon. But I don't really care what the price is, as long as there's
an e85 pump. If I could pay at the pump with bitcoin, I wouldn't even look
at the price, I'd only care if my tank got filled up or if I have to drive
slower to get better mileage.
Hell, I'd have an app that would tell me what gas station to go to that got
me the best miles per bitcoin based on where I actually wanted to go.

MtGox is one of the largest public faces of the code being developed here. If
the public perception is that this is a bitcoin protocol flaw, then we need
some damned strong and compelling public arguments about why it ain't so. But
after some thought, that's not the critical issue I want to raise on this list.
If something about the implementation, the protocol, of bitcoin-qt or bitcoind
makes it easy for an attacker to mutate transactions and hard for an 'end-user'
such as MtGox to confirm payments, then we've got a fundamental user-interface
flaw.
We can get all indignant about RTFM or telling the users they are idiots, but
that's not really going to be good for long-term adoption and use.
My opinion is part of the development process should be to react to public
perceptions of how the code is being used (and mis-used), and how the market is
being manipulated, and try to improve it so the whole system is stable,
predictable, and friendly to users.

This isn't about developers.
This is about venture capitalists taking lots of money from unsuspecting
investors, and MtGox is in a psy-ops PR-war with multiple other exchanges
and lots of places that would like to take their market share and money.
Why do you want the 'official' PR-spin-war response approved by the official
bitcoin developer PR-firm, who's probably being paid by competitors to MtGox?
Name me one single person with commit access to the bitcoin github repository
who is *independent* of any venture capital or other 'investment' connections.
Fortunately for the rest of us, any dumb farmer can create a copycatcoin
Hell, if MtGox hosted their *own* fork of bitcoin I'd run that in a heartbeat.
And for full disclosure, I am available for consulting if anyone would like
assistance setting up and hosting an independent source code repository that
includes good automated regression tests.

Thank you.
I also appreciate your commentary[1], and willingness to list your investment
position. What I'm concerned about are people who have signed non-disclosure
agreements or who's salary/equity/whatever depend on people who are experts
at manipulating markets to take naive investors money.
Independent is also a state of mind as much as it is about financial connections.
What pisses me off here is that a huge amount of wealth just changed hands based
on MtGox's press release, and it stinks of insider trading. I still maintain the
best outcome would be for MtGox to AGPLv3 release their code, and then those of
us that understand it would be able to have a public technical discussion about
how to fix it, and MtGox would still maintain their intellectual property
ownership position.
This, however, cuts off a significant revenue stream for people who take money
making market bets 5 minutes before the information goes public, so I expect
the likelyhood of such an outbreak of sanity is quite low.
