14:07 <fluffypony> measurement study of JoinMarket

14:13 <waxwing> fluffypony: looks to be an update of the earlier version from last year(? forget exact date). thanks for ping.

14:13 <fluffypony> yeah it is - 2015/2016 stuff

14:16 <waxwing> i had a number of comments on the analysis, it'll take me a while to see if any of them were addressed in this new version.

14:17 <waxwing> the most critical one for me was, the assumption that you can swamp the bottom of the orderbook and thus use sybil to link depends on price sensitivity of Taker's choice. for example, "random under a maximum" can make it far harder than "random with strong weighting to cheaper".

14:41 <betawaffle> when is someone going to revolutionize the security and privacy of telephony?

14:43 <ociule> betawaffle: if you send me enough BTC, I'll do an ICO

14:43 <betawaffle> :D

14:43 <ociule> what kind of privacy anyway ? against what threat model ?

14:43 <ociule> ah robocalls

14:44 <betawaffle> all-seeing governments, maybe? (and spam/junk, though that's not so much a privacy issue)

14:44 <betawaffle> i'm not sure if both are achievable

20:44 <adiabat> hey - random idea that might be fun: what if in the 80 byte header, the prevHash was instead a prevMerkleRoot

20:44 <adiabat> which is just a merkle root of all previous block headers

20:45 Guest96074 has quit [Ping timeout: 260 seconds]

20:46 <adiabat> I mean it doesn't really change anything, but might allow SPV nodes to keep less on disk... though actually for verifying the next header, you still need log(n) hashes

20:46 <adiabat> anyway it's a hard fork and probably not much more efficient but it's a fun thing to sketch out

20:46 <sipa> that's an approach used by compact spv proofs

20:47 <sipa> adiabat: and something related (though not an entire tree, just a skiplist) was proposed by amiller here: https://bitcointalk.org/index.php?topic=98986.0

20:48 <adiabat> ah, the "lucky headers" thing

20:48 <adiabat> cool will look at that
