I'd also like to point out the obvious: git uses the previous hash as part
of the formula to generate the current commit hash thus tampering with
history while possible would be instantly noticed because we all have
copies of the repository. Tampering would be completely evident (pushes
would fail for a start, and even simple merges would bork). It's just not
possible to tamper with the repository without it being discovered, even
with collusion (or strong arming) of github.
The social benefits of github make it idea for open source projects that
want community participation. The barrier to entry is low. The only "weak"
spot of github is the releases section, but since we don't actually
distribute Bitcoin from github the point is moot.
I think github haters fail to see the vast benefits of a social hub like
github. Their issue tracker may not be as sophisticated, it serves well and
the project is extremely productive.
Don't shoot yourself in the foot - a move away from github would be a
disaster for the project.
When you look at the attack surface of using github, it's pretty small and
would not go unnoticed, thus nullifying concern.

The dns seeder works pretty efficiently in my experience. Maybe we need

I think the issue being discussed is do you orphan an entire block causing
distress to users as well, or try to just cause distress just to the evil
miner? This discussion is about exploring the ramifications of all these
options.
I think you are also forgetting that, miners can implement their own
filters and behaviours without anyone's consent. So having an open
discussion and exploring all possibilities can only be a good thing before
someone goes off an implements a change without taking into account other
points of view they may not have considered yet.

📝 Original message:I agree with you Jeff. The unit switch needs to happen once and once only,
but that is exactly why I said the defaults really need to change in
Bitcoin-Qt since that is still the main reference implementation and it
will influence others.
Bitpay could also take the lead here and make the switch to their defaults.
That would greatly assist the uBTC movement.
Regardless of what anyone says, Bitcoin-Qt is still the main reference
implementation and the best way to encourage a change in the community at
large is for the default units to be changed here. Core devs can surely
garner enough consensus among themselves to accept and merge a PR to that
effect. That will send a message, more than anything else that can be done.

📝 Original message:Gavin,
You have pretty much nailed my intent in both respects. This sets up a way
to negotiate the address and abstract away the nasty details of finding
public keys from bitcoin addresses, and provides a nice clean way for
redemption abstracting away the long strings of hex.
For redemption, I think as each party signs the tx if the script returns
true, it would be acceptable to just go right ahead and broadcast it, or
maybe as you suggest all signatures go back to the initiating party and
they do the final work.
I very much like the idea of assuming each party uses HD wallets, that
certainly simplifies things greatly. I also like the use of email addresses
as a negotiation medium, but I also wonder if this could be made agnostic
in any BIP proposal so it could work with other communication mediums like
bitmessage for example (just forward thinking anonymity a little).
I definitely think there is a need for a protocol because multisig,
regardless of the application has two technically involved steps:
negotiation of an address, and redemption of any subsequently encumbered
funds. A protocol would enable different wallet implementations to
participate in such a transaction and make wide-spread use much more likely
and possible.

📅 Original date posted:2014-03-10
📝 Original message:I was wondering if there would be merit in a kind of BIP for a payment
protocol using multisig?
Currently, setting up a multisig is quite a feat. Users have to exchange
public keys, work out how to get the public keys from their addresses. If
one of the parties are not savvy enough, an malicious party could easily be
setup that was 2 of 3 instead of 2 of 2 where the malicious party generates
the multisig address+script and thus be able to run off with funds anyway.
It's also terribly complex to generate and keep track of. There's been a
nice attempt at creating an browser interface at coinb.in/multisig but it
still lacks the kind of ease with created by the payment protocol. If there
was a BIP then it would go a long way to aiding future usability of
multisig wallet implementations.
What are your thoughts?

Actually, this is unnecessary since github allows editing of files directly
on the site and the it will submit as a pull request. You can even update
by visiting your fork (it creates this automatically and a topic branch)
and make more edits and it will add to your PR. There is basically no
barrier for non techy people to contribute.

The problem is all addresses are reusable and to an average user, addresses
are already reusable so there is little to distinguish the address format.
It might be better to call it a "public address" in common terminology.

It's great to see the many ways wallet authors try to protect users from
easy to make mistakes, especially against losing funds.
But this issues isn't confined to custom transaction - some wallet
implementations have a fee field and almost all wallets allow the fee rate
to be configured in preferences. Sanity checking is sensible where a user
can override the calculated fee. Some wallets don't allow the fee to be
adjusted at all, but quite a few do.

0.05 BTC transaction[1], oops. There was another recently where someone
paid a fee of about 200BTC which fortunately the pool operator refunded.
It just occurs to me this kind of sad story could be averted if wallets
implemented a confirmation box if the fee amount seems crazy - for example,

I realise the exact details of this might need to be fleshed out given we
want flexible fees, but it should be pretty simple to agree with what looks
like an unusually large fee according to the going rate.

Simple verification relies on being able to answer the email sent to the
person in the whois records, or standard admin/webmaster@ addresses to
prove ownership of the domain. This is a good point to note -
bitcoin.orgshould not get a simple certificate, but one that requires
identify
verification for the person/org who is applying. They are more expensive.

You cannot MITM SSL connections - it will cause a browser warning.
I do not have the means, but it has been demonstrated some people are
performing BGP redirections, daily, and on a massive scale... and it's a
problem, because BGP was designed on implicit trust.

You are right that the CA system is not full-proof, one CA was caught
issuing a bogus certificate on purpose a while back, I forgot the name but
it resulted in CA certificate revokation and the entire company being
blacklisted from Firefox and Google Chrome forever - basically a summary
corporate execution. I personally imagine the CIA or other state actor
could just quietly buy up an already trusted CA and abuse them. But it's
clear, people are watching, and if a CA is caught once, that's the end of
their business forever: Firefox and Google demonstrated that. The strategy
is possibly too expensive and risky to carry off which is maybe why they
don't do it.
What has been noted with all the Snowden leaks, and with the Lavabit case,
the security agencies did not get bogus certificates issued, they still got
court orders, or other deception to get hold of the encryption certificates
of their targets instead of issuing their own so they could listen in.
The CA system is not full proof, but it is what we have. Similar arguments
have been made against the use of identity certificates for bitcoin, but
that hasnt stopped it's inclusion in the bitcoin payment protocol.
Anyway, I take your points, but this is an area I am quite passionate about
so it's important for me to be clear.

Let me clarify. SSL renders BGP redirection useless because the browser
holds the signatures of CA's it trusts: an attacker cannot spoof a
certificate because it needs to be signed by a trusted CA: that's the point
of SSL, it encrypts and proves identity, the latter part is what thwarts
MITM. If there was an MITM the browser screams pretty loudly about it with
a big threat warning interstitial.

It's not just about trust, there is the robustness factor: what if he
becomes sick, unavailable, hit by a bus? Others need the ability to pickup
and run with it. The control over the domain (including ability to renew
registration, alter nameservers) needs to be with more than one person.
That's why I suggest using the same people who have control over the
software project at sf,github.

What do you suggest though? We will need to trust someone (even in a group
each person can act autonomously).
The only thing I can suggest would be to hand the keys to the bitcoin
project lead.
Otherwise, who has admin rights to the code projects
(github/sourceforge/this mailing list)? Those people have proven they can
be trusted so far.

Malicious actors with root access to the server is another issue entirely.
Sure it's a problem, but it is not an argument not to have a properly
signed SSL certificate.
With out one, the exploit can be performed on routers to redirect traffic
through a third party alter the content of the site (like the links on
bitcoin.org to various wallet projects) and then onto the correct
destination. SSL at least mitigates that. For example it would be trivial
to impersonate Electrum's site or whatever, "change" the link on the fly
that appears on the trusted source bitcoin.org via BGP redirection. Now
users will be directed to the scammers site which could be identical except
for domain name and of course malicious binaries.
BGP redirection is a reality and can be exploited without much
expense/effort. MITM is a real world threat, not some theoretical
possibility - reports show it's happening on an unprecedented scale. SSL is
essential - that's a no-brainer. Sure other measures are important, but
without SSL there is almost no point to any of the other options.
SSL is so considered so important that the *HTTP 2.0 spec might be SSL
only*according to recent discussions at the W3C (
http://lists.w3.org/Archives/Public/ietf-http-wg/2013OctDec/0625.html).

That is exactly the point and the moment they are publicly available you
cannot stop people talking about it or noticing it, or posting official

https://bitcointalk.org/index.php?topic=364353.0. Was that an official

Why would it be made available for download at sourceforge.net if it's not
actually released? The files are available here:
http://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.8.6/ and
people watch the sf rss feeds etc...
Seems to me like there needs to be a better release workflow. As far as the
world is concerned, they are downloading the 0.8.6 and there is a lot of
community buzz about it already.
IMO, to avoid that, no files should be placed online unless they are the
official release.

Refunds in this circumstance would be problematic because someone is going
to lose because they have to pay the fee. If the sender's money is refunded
minus the fee, they will be unhappy. And the merchant will be unhappy about
having had an unacceptable transaction they have to send back, and eat a
fee for the privilege.
This kind of situation needs to be avoided at all costs.

I respectfully disagree. Senders need their funds to be received. The
incentive is right there. Miners want mining fees. So if you want to pay
for something, you need to make sure payment arrives. Senders know that if
they exclude the fee it might not arrive at all. Miners increasingly ignore
no or low fees. So those two agents together ensure there is a fee more
than not. If what you said was true, we would hardly see fees being paid at
all, but on the contrary we see lots of fees, and much higher than the
minimum 0.0001/kb rate that is currently required.
Merchants will just include ridiculous fees - there are some exchanges that
do it already - MtGox being the famous example requires a 0.001 fee 10x
higher than the network rate - the CEO does it because he says "it's
better". That's not a fee going to MtGox, that is the miner fee and they
have no plans to reduce it.
Typically vendor software may not get updated and or lag behind with fat
fees never decreasing or decreasing way too slowly - it's just not fluid or
dynamic enough when it rests with the vendor.
However, receivers do want a fee attached,

No - receivers want to be paid. If they are not paid they wont dispatch the
goods or service. Neither party is happy in that circumstance. The

Miners cant lie about fees accepted because that's part of the transaction.
When Alice sends funds to Bob it includes the fee information and that is
included in the block. There is no way to fake it. The average fee paid is
provable - so there is no need to query nodes at all, you simply look at
the blockchain. You dont even need to write it into the blockchain since it
can be calculated from the blockchain, it would just make it simpler.

📝 Original message:I dont like the idea of putting the min fee in the hands of the receiver.
Seems like that will work against the best interests of senders in the long
run.
Why not try a different path of calculating the min fee like difficulty
retarget. You can analyse the last 2016 blocks to find the average fee
accepted per kb (which would include transactions that were included
without fees) and then write that into the block as a soft recommendation
that wallets could use in the UI. This way the price can vary up and down
according to what people were willing to spend on fees and miners willing
to accept.
I absolutely do not trust vendors to set fees. I think it has to be based
on what senders are willing to pay and what miners are willing to accept.

I wasnt suggesting people add drafts willy nilly to the repository.
When working on a proposal you can work on it in your own fork and create a
PR. When it's ready to be accepted as a working draft by the WG, then it
can be merged into the draft folder. At which point, PRs are made to that
draft copy until it gets into a ready state to become final. If passed,
it's moved to the accepted/ folder.
This way random BIPS cannot be added to the drafts/ folder in the official
repo. They are only added once they are accepted as a working draft
proposal by Gavin or whatever. Now you get all the niceties of github
workflow for collaboration and tweaking of the draft proposal.

It's quite normal for standards bodies to allocate numbers when in draft
status. If they don't pass, they don't pass - they are clearly labelled
DRAFTs.
+1 on having things in a github repository. Much better for collaboration,

Hrm. Freudian slip... you know what I mean *fee, not fed.... :-)
.... so in response to those saying the fees are $0.20, actually it's more
like $0.042 at current prices.

If you are talking about user interface, I don't think you have to be
technically correct. It must make sense to the user.
A user cares about his balance, and did a payment "go through", and "did my
payment arrive/clear".
The UI is for their benefit.

Maybe, but again from the user's perspective they pay someone, and they
receive money - just like you do with paypal using an email address.
The technical bits in the middle dont matter to the user and trying to crap
stuff in to be technically correct is just confusing to them.
The UI needs to be about the user and fit with his experience of the world.

I think people are more familiar with check clearance - "the payment/check
has cleared".
If "confirmation" and "n confirmations" together are problematic, I'd talk
about "cleared payments" and "n confirmations"
So "a payment clears after one confirmation, but you might want to wait
until the payment has been confirmed n times".
Then at least you are not using the same word for two different meanings
and you're using stuff more familiar in popular lexicon.
I dont think it's helpful for users if we use the word "blocks".
Without the technical details, I just explain to normal bitcoin users that
the Bitcoin network checks and confirms the payment is valid (multiple
times).
I think we all know the problems with the term "address". People naturally

I think "key id" is a bit alien at user level - it's not something they are
used to.
For years, people had a problem with "email address", instead using "email
number" but they got there eventually. Most people nowadays use "email
address"
So "payment address" or "bitcoin address" make better sense here when
qualified as a "<foo> address" and not just an "address"
You could also call it "payment id", but I dont think "invoice id" since
no-one pays to an invoice id that's just a reference for a payment, not the
destination.
People are very familiar with Paypal these days, and are familiar with
"paypal address" or their "paypal id" so again I think valid contenders are
"bitcoin address" or "bitcoin id".
