< jnewbery>
but this isn't misinterpreting BIP155. BIP155 is totally irrelevant for links that don't support address relay
< laanwj>
no, I'm arguing against misinterpreting BIP155
< laanwj>
I did think a signal whether a peer is interested in address messages or not is orthogonal to what messages it supports or not, there was discussion to include this in BIP155 at some point but it wasnm't
< jonatack>
those do seem like separate concerns / flags / BIPs etc
< jonatack>
in the BIP155 discussions nearly a year ago, it was decided that disable addr was a separate concern from BIP155-capable, thus the current implementation
< laanwj>
vasild: yes i remember during the bip155 discussion there were some ideas to also incorporate 'do not send me addresses at all', but this was not done, i had to think of this with #22245
2021-06-15
< sipa>
someone who doesn't care about addrv2 isn't going to implement BIP155, and thus isn't going to send sendaddrv2 either?
< sipa>
in order to implement BIP339 you must send wtxidrelay
< sipa>
but you're free not to implement BIP339
< ariard>
sounds more an oddity of bip339
< amiti>
and then there was a question about BIP155 on #22245, I've posted my thoughts on the PR, but want to give anyone the chance to raise questions / any remaining concerns
< sipa>
i saw some discussion with laanwj about bip155 changes, so maybe it's useful

1. I think it's probably time to merge https://github.com/bitcoin/bips/pull/1116 (adding Kalle as BIP editor). It was proposed three weeks ago, has 15 ACKs, and no substantive opposition.
< Arvidt>
What is that version "v22.0" on the last line of https://github.com/bitcoin/bitcoin/blob/master/doc/bips.md ? Is it not Bitcoin version (they all start with v0.) ? Would make sense, since V.0.22 is not released yet and there are backports to 0.20 and 0.21 ongoing.

< hugohn>
@luke-jr the inclusion of things like NO_ENCRYPTION mode and BIP39-like PBKDF2 function parameters in the spec is to help with backward compatibility. IMO the main thing that might not be backward compatible with all vendors is the stateful nature of the Signers, which I have stated in the Compatibility section.
< michaelfolkson>
hugohn: I personally think it would be overkill to give the BIPs repo its own org
< michaelfolkson>
hugohn: They aren't really bundled with the Core project. It is true the BIPs repo is under the Bitcoin Core GitHub org but no Bitcoin Core maintainers merge BIP PRs afaik so I think it is fine under the Core org
< michaelfolkson>
I think there will be future discussions on a revised BIP process once (hopefully) Taproot activation is completed hugohn if you'd like to engage with that https://github.com/bitcoin/bips/pull/1015
< wumpus>
in any case, this discussion is kind of off-topic here, the bitcoin core project is one implementation, that the current BIPs repository is in the same orginazation is a historical artifact, it does not mean BIPs 'belong' to bitcoin core or something like that
< wumpus>
you mean like BIP1 and 2?
< hugohn>
right. if it's not a simple sequence generator, a BIP on BIPs probably makes more sense.
< rebroad>
MarcoFalke i only just realised that BIP111 didn't get updated with the changes I proposed back in 2016... so yeah, nevermind... i guess i wasn't keeping my eye on the ball back in 2016!
2021-05-01
< hsjoberg>
Yeah thanks, that's what I thought as well, and AFAICT the reason why we even have such high threshold for BIP9
2021-04-28
< sipa>
BIP342 specifically contains a (somewhat unrelated) improvement of introducing "key versions", specifically intended for things like that
< sipa>
depends on whether you mean taproot in reference to the technology to tweak keys as a commitment scheme, or the BIP341/BIP342 proposal
2021-04-25
< luke-jr>
I'm down to 8 tabs of BIPs PRs, one of which is presumably 1104; I don't know how involved the tab(s) before that are to go through
< murch>
Well, some wallets implemented experimental Taproot support before BIP350
< luke-jr>
jeremyrubin: BIPs PRs merging slowly is not a new thing at all.
< luke-jr>
harding: right now, I'm churning through dealing with the rebase of BIP8 on top of the ST stuff. I suppose that might go faster if there were people willing to review it. But frankly then it almost sounds like I'm holding the BIPs hostage, and I don't want to do that either.
< luke-jr>
as a reminder, though, BIPs *are* just documentation, so there really shouldn't need to be a rush
< jnewbery>
it does seem somewhat of a centralization problem. The BIPs repo is a venue for sharing proposed changes to Bitcoin, and one person decides who can update it, and also decides whether or not they should ever be replaced/supplemented?
< meshcollider>
jeremyrubin: I interpret that "long winded discussion" bit to be about the BIPs themselves, not the process of adding an editor
< ariard>
jeremyrubin: on the other point, I don't think bip2 recommend bitcoin-core-dev as a venue, maybe better suitted to #bitcoin or #bitcoin-wizards
< wumpus>
right the role of BIP editors is to follow the BIP1/2 process, not to pass personal judgement on BIPs besides very basic style criteria
< jeremyrubin>
As far as you've represented previously, you haven't had time to even look at the BIP341 changes which is why it's not merged.
< jnewbery>
I suggest that we lighten his load by adding a second BIP editor. BIP2 allows multiple BIP editors and refers to plural BIP editors in several places, eg "The BIP editors are intended to fulfill administrative and editorial responsibilities. The BIP editors monitor BIP changes, and update BIP headers as appropriate."

< aj>
release notes and an update of bips.md ("without mainnet activation") probably should be done before rc1?
< luke-jr>
kallewoof: maybe there should be a new BIP, also eliminating BIP Comments and adding Markdown back into the mix. certain people have decided to skip BIPs because they don't like people leaving comments, and I can only guess the Lightning BOLT stuff is because they prefer markdown…
< luke-jr>
ultimately BIP9 uses starttime to choose a height based on difficulty-period boundaries (2 weeks long)
< luke-jr>
provoostenator: after all, it had plenty of review and was RTM weeks before this BIP9 stuff, and still wasn't merged anyway
< luke-jr>
provoostenator: MarcoFalke already blocked me from doing so; I have no reason to expect decent behaviour from devs strongarming BIP9 back in at this point anyway. Something is clearly going on behind the scenes.

[bitcoin] fanquake merged pull request #21377: Speedy trial support for versionbits (master...202103-bip9-speedy-trial-support) https://github.com/bitcoin/bitcoin/pull/21377
2021-04-14
< luke-jr>
or to be more correct, people who don't consider it a triviality, are unanimously in favour of BIP8
< luke-jr>
it's not triviality except to BIP9 advocates
< emzy>
fwiw I was prefering bip8 and ok with bip9 in the beginning. And I think many thought the same at that time.
< jeremyrubin>
Sorry if this is line noise for this channel -- but this is the best job I could do at breaking down the claim that BIP8 has consensus (LOT=?) and ST/MTP does not
< luke-jr>
jeremyrubin: BIP8 doesn't require LOT for ST any more than BIP9 does
< jeremyrubin>
Overall I feel relativelty confident based on this review dismissing the notion that BIP8 has consensus and ST/MTP does not
< jeremyrubin>
Further in support of BIP8's consensus being questionable earlier on, I think harding has had a very good read on the community in general. I don't beleive he would have included BIP9 in his proposal as an option if he thought the community was decisive
< jeremyrubin>
Further, the type of consensus around BIP8 in these meeting logs (maybe it's somewhere else, figure the meetings are more relevant than twitter/reddit) is not super high quality IMO because it's mainly ACK'ing the properties of BIP8 as opposed to the specific implementation
< jeremyrubin>
"but we already agreed to XXX for BIP8" doesn't hold when a keystone component of BIP8 (LOT) is what made ST a thing in the first place.
< jeremyrubin>
so it seems inaccurate to me to label BIP8 as having consensus when a key parameter did not
< jeremyrubin>
I can see why luke-jr and michaelfolkson think there might be consensus on BIP8, but I think they are viewing the process as "gradient descent on a continuos surface" as opposed to a discontinuous process.
< jeremyrubin>
and BIP8 requires *a choice* of that
< jeremyrubin>
(in fact, it's usually preferable to be descriptive otherwise we have useless BIPs clogging the numberspace)
< jeremyrubin>
BIPs are often descriptive
< jeremyrubin>
in fact at this point it probably has more review than any BIP8 anything has ever had
< jeremyrubin>
and you've extrapolated BIP9 RIP ==> MTP cannot be used
< jeremyrubin>
I see people caring about the *properties* of BIP8 vs BIP9, not excluding MTP being used in the future
< jeremyrubin>
reading through http://gnusha.org/taproot-activation/2021-02-02.log, based on which michaelfolkson bases claim that BIP9 is "dead" and therefore MTP can't be used, TBH I just don't see that being the emergent agreement
< luke-jr>
anyway, how things get documented in BIPs is trivial in comparison to the real issues
< jeremyrubin>
luke-jr: community's consensus aroudn BIP8 WHERE
< luke-jr>
most have never even heard of 21377, and it is opposed to the community's consensus aroudn BIP8
< luke-jr>
the community is almost unanimous in favour of BIP8
< jeremyrubin>
What test is BIP8 passing that 21377 is not
< luke-jr>
ST/BIP8 had (has?) widespread support, not ST/BIP9
< jeremyrubin>
Luke, what test is BIP8 passing w.r.t. consensus that ST is not?
< jeremyrubin>
he's consistently failed to answer questions like "what is incompatible with ST" or "what definition of consensus are you using that passes BIP8 and not ST"
< jeremyrubin>
Maybe remove BIP8 LOT=true?
< jeremyrubin>
What is BIP8 LOT=? satisfying
< jeremyrubin>
luke-jr can you give a definition for what consensus is? Is there a concrete and consistent definition you are applying that BIP8 LOT=true is satisfying that the current ST MTP start/stop + height of activation minimum is not meeting that can be applied here and in the future?
< jonatack>
jamesob: achow101: same, i'm still reviewing. did a first pass to get the code and bips in my head, need to do another one
< luke-jr>
sipa: there is agreement on BIP8, yes
< jeremyrubin>
I'll reiterate here: luke-jr luke-jr can you give a definition for what consensus is? Is there a concrete and consistent definition you are applying that BIP8 LOT=true is satisfying that the current ST MTP start/stop + height of activation minimum is not meeting that can be applied here and in the future?

< sipa>
luke-jr: BIP68 treats it as signed, afaik
2021-04-08

which says: " The idea can be implemented on top of either Bitcoin Core's existing BIP9 code or its proposed BIP8 patchset.[6]"

< ariard>

< sipa>
if you're going by reading the spec by the letter... what does bip60"s fRelay flag even mean for a client that chooses not.to implement bip37?
< aj>
ariard: I run a -blocksonly node. You run a bip60 compliant node. I tell you fRelay=false. You don't send me any txes. You told me fRelay=true. Therefore I can send you a tx, without violating bip60.
< ariard>
aj: my point was bip37 original scope was unclear if it concerns only inv(tx) or any tx-related message, bip338 has the merit to clarify

andytoshi: I've pushed the updated tests to my bips pr too
< andytoshi>
achow101: in BIP174, the test vector "PSBT with unknown types in the inputs" describes an input which has keytype 0x0f and key 0102030405060708. this is a valid PSBT
< sipa>
so i guess we could list BIP60 as implemented, actually
< MarcoFalke>
Bitcoin Core implements BIP60, but doesn't require peers to implement it. (Like any other optional BIP)
< ariard>
even the original bip37 is really unclear if fRelay semantic is to disable tx-relay or just tx-announcement
< luke-jr>
it doesn't require breakign non-BIP60 peers
< sdaftuar>
sipa: but we're compatible with bip60 peers, and i think we now expect our peers to always read our fRelay flag if its' set to false, right?
< sipa>
luke-jr: BIP60 is about predictably-sized version messages, not just the fRelay flag
< sipa>
it'd probably not be a bad idea to have bip32 derivation in the test framework

"I like a hidden option in Core which is always there from day one, which is lot=true or taproot-bip8-lot-true or something that would change lockinontimeout to true and also change the default user agent string so you can tell people are running it.

I don't even think recommending bip39 support to 'newbies' would be a good idea. ideally there would be an easy way to connect a hardware wallet and get descriptors that way vs bip39 on your computer

< dr_orlovsky>
so BIP43-type new purpose value for P2TR will be a good solution in this respect as well?
< sipa>
i guess that means this whole point is moot, and we should probably have a deep look at proving security of ECDSA and Schnorr signatures of linearly related keys (as those created by P2C-tweaking or BIP32 derivation result)
< sipa>
yeah, you'll probably want a separate bip32 path for P2TR outputs; but that has nothing to do with ECDSA/Schnorr; you just don't want to reuse the same keys
< sipa>
i don't know if that needs a standard like BIP43 - perhaps it helps

luke-jr: what are the relevant PRs and issues? The two from aj to the BIP8 and your #19573?
< sdaftuar>
sipa: whether bips are the right place or not is unclear to me, but i think communicating relay policies like this so that 3rd party wallets know what behavior to aim for is helpful. in the case of bip125, my hesitation towards amending or redrafting is that we should fix the implementation in other ways anyway
< sipa>
if there really is a discrepancy between bip125 and what bitcoin core implements, it could be mentioned in doc/bips.md
< sipa>
i don't think these things belong in BIPs
2021-01-20
< pinheadmz>
is BIP125 (RBF) accurate with the implementation? Specifically, is it the absolute fees that are compared between replaces and replacing tx? or the fee rate?
< sdaftuar>
sipa: my understanding as well that there are no BIPs on it
< sipa>
i don't think it's unreasonable to recommend not relaying addresses to disabletx peers; so far addr relay is completely local policy anyway with no BIPs discussing it at all afaik
< jnewbery>
sdaftuar: do you have any further thoughts about what a future addr relay negotiation method would look like? I know you were pushing for something similar with BIP155
< sdaftuar>
but to do all that, we need to give nodes a way to know that an inbound peer is a block-relay-only peer. currently block-relay-only peers use the fRelay flag from BIP37 to instruct their peer they don't want transactions
< sdaftuar>
but BIP37 allows for transaction relay to resume with a FILTERCLEAR message

but I failed to verify the callers of the constructor CSubNet(CNetAddr&) which used to create one-host-subnet before and would also "work" for torv2 addresses (in the code before bip155) by matching a single address
< vasild>
jonatack: when I extended CNetAddr to support longer-than-16-bytes addresses (as part of bip155) I also changed CSubNet to only handle ipv4 and ipv6 addresses - because it contains char netmask[16]; it makes no sense to apply it to e.g. 32 byte torv3 address

If you consider BIP37 and optional standard, then it's not really a violation of the protocol to send tx INVs after receiving a version with fRelay = false

question about fuzzing. we use regtest chain params, but in corups for src/test/fuzz/descriptor_parse.cpp I see xprv keys. As a result fuzzing don't cover code paths with valid keys for bip32 decriptors. I tried to add initial seeds with tprv, but fuzzer doesn't detect any new edges covered. What do I miss?

bip322 proves the ability to spend coins sent to a particular bitcoin address; a lightning equivalent sounds like it would need a lightning-specific solution

[bitcoin] sipa opened pull request #20189: Switch to BIP341's suggested scheme for outputs without script (master...202010_taproot_std_noscript) https://github.com/bitcoin/bitcoin/pull/20189
< sipa>
there is one context where we actually treat someone with a private key as an attacker in BIP340, and it's a rather unusual requirement: nobody (even those with private keys) should be able to construct a signature for which the single-sig validation and batch-validation algorithm produce a different result (with more than negligible probability)

sipa, yeah i understand now, i was confused by the bip340 language about malleability
< sipa>
phantomcircuit: to be clear, the bip340 signing algorithm is deterministic if no auxiliary randomness is used

luke-jr: when would an ack be necessary for marking 'obsolete'? i thought it would be analogous to 'final' which you seem to wait for an explicit ack for here: https://github.com/bitcoin/bips/pull/926
