Re: [bitcoin-dev] [Pre-BIP] Fee Accounts

Ok, got it. Won't waste anyone's time on terminology pedantism. The model that I proposed above is simply what *any* correct timestamping service must do. If OTS does not follow that model, then I suspect whatever OTS is, is provably incorrect or, in this context, unreliable, even when servers

Re: [bitcoin-dev] [Pre-BIP] Fee Accounts

the 'lots of people' stuff (get confused, can't figure out what i'm quoting, actually are reading this conversation) is an appeal to an authority that doesn't exist. If something is unclear to you, let me know. If it's unclear to a supposed existential person or set of persons, they can let me

Re: [bitcoin-dev] [Pre-BIP] Fee Accounts

That's not really pinning; painning usually refers to pinning something to the bottom of the mempool whereas these mechanisms make it easier to guarantee that progress can be made on confirming the transactions you're interested in. Often times in these protocols "the call is coming inside the

Thanks for the info. > you could "sponsor yourself" directly or through a cycle involving > 1 txn. Ah I see, because the sighash flags aren't used to create the TXID. I don't really see the problem with cycles tho. Could a cycle cause problems for anyone? Seems like it would be a harmless waste

Hmm, I don't know anything about SIGHASH_BUNDLE. The only references online I can find are just mentions (mostly from you). What is SIGHASH_BUNDLE? > unless you're binding a WTXID That could work, but it would exclude cases where you have a transaction that has already been partially signed and

Re: [bitcoin-dev] [Pre-BIP] Fee Accounts

I see, its not primarily to make it cheaper to append fees, but also allows appending fees in cases that aren't possible now. Is that right? I can certainly see the benefit of a more general way to add a fee to any transaction, regardless of whether you're related to that transaction or not. How

Re: [bitcoin-dev] [Pre-BIP] Fee Accounts

Ah my bad i misread what you were saying as being about SIGHASH_BUNDLE like proposals. For what you're discussing, I previously proposed https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2020-September/018168.html which is similar. The benefit of the OP_VER output is that SIGHASH_EXTERNAL

Re: [bitcoin-dev] [Pre-BIP] Fee Accounts

The issue with sighash flags is that because you make transactions third party malleable it becomes possible to bundle and unbundle transactions. This means there are circumstances where an attacker could e.g. see your txn, and then add a lot of junk change/inputs + 25 descendants and strongly

Re: [bitcoin-dev] [Pre-BIP] Fee Accounts

Can you clarify what you mean by "improve the situation"? There's a potential mild bytes savings, but the bigger deal is that the API should be much less vulnerable to pinning issues, fix dust leakage for eltoo like protocols, and just generally allow protocol designs to be fully abstracted from

Do you have any back-of-the-napkin math on quantifying how much this would improve the situation vs existing methods (eg cpfp)? On Sat, Jan 1, 2022 at 2:04 PM Jeremy via bitcoin-dev < bitcoin-dev@lists.linuxfoundation.org> wrote: > Happy new years devs, > > I figured I would share some
