mircea_popescu: <mircea_popescu> you can extract packets but basically end up re=implementing gpg.
mircea_popescu: Framedragger he just got a pile of encrypted-and-signed crap. how does he get message and signature now.
mircea_popescu: ben_vulpes for bonus points, check if it checks beyond "short fp matches"
mircea_popescu: you can extract packets but basically end up re=implementing gpg.
mircea_popescu: there's reasons we don't like the sign-and-encrypt bs.
mircea_popescu: asciilifeform> davout: FUCK spendingbeforeconfirmed. << yeah pretty bad idea in retrospect.
mircea_popescu: it's actually how the whole "not match earlier nonspent txn" got added. the author is the death row inmate peter wuille.
mircea_popescu: asciilifeform actually look up that bip30 thing, it's related.
mircea_popescu: unlike elderly parents, was giving benefit of teh theory.
mircea_popescu: so of these tens of thousands of same-hash coinbases, which were hundreds if not thousands of times reorged, which is the parentless coinbase ?
mircea_popescu: you're a fine gent, standing on a pile of "because so and so, the sky is falling." "well... i don't see it fallen" "show me why not!"
mircea_popescu: now. a block with these gets reorged. ALSO happened 100s of times to date.
mircea_popescu: and this will ALWAYS resut in coinbase in this sense with same hash.
mircea_popescu: okay. so basically you want a miner to mine twice to the same address. right ?
mircea_popescu: i'm sorry, you're trying to recreate a coinbase as in, miner subsidy ?
mircea_popescu: one that's been spent has been spent. ergo is a doublespend.
mircea_popescu: now, the cost to mine a same-hash tx that is also meaningful other than garbage is not trivial.
mircea_popescu: altogether not a bad idea to make a set of test chains as per the tsting discussion last week. this can surely be both part of it and the incentive to do it.
mircea_popescu: you're welcome to do it any of the three ways, but rly nao.
mircea_popescu: you got a good point, but it's just part of the story as-is.
mircea_popescu: well, you can either try to replicate this, if you wish, irl, or else show a case in blockchain where it happened, after 2011, or else simmer down and keep digging.
mircea_popescu: the ~exact~ ~specific~ ~pinpoint-for-me-in-lxr-or-bust~ mechanism of this is not specified.
mircea_popescu: should dr evil attempt to re-mine C1 as part of T3 in block 4, this will fail, because T1 still exists in blockchain
mircea_popescu: then, block 3 is orphaned. this wipes any mention of C1/C2's hash from index.
mircea_popescu: even later on, coinbase C2 with same hash as C1 is introduced in block 3.
☟︎ mircea_popescu: let's see the practical consequence where you simmer the fuck down and stop oversignalling by a factor of fifty trillion ONCE!!! in your life! one ounce work ten bushels sky is falling good god.
mircea_popescu: and then he wants to re-introduce original. but he can't. because doublespent.
mircea_popescu: he'd be doing this by himself as block 60 (really, why all the 0s ? you need them for something ?) which doublespends block 50 won't be accepted by eg me.
mircea_popescu: so restate. and also spare me specifications that c ain't b, obviously it isn't, if it were you'd call it b.
mircea_popescu: do you mean, "it removes transaction entirely but it doesn't nor could correcty undo the damage to the ball of yarn" ?
mircea_popescu: in other news, camembert, lomo horneado + boiled corn on the cobb, primo breakfast a++ would breakfast again
mircea_popescu: i suppose that was a hook intended for some kind of anonimization thatnever made it in.
mircea_popescu: it's 64 bits until year 13500 and 128 bits from there on until year 1mn etc
mircea_popescu: now, i do propose that it is actually better to have undefined-sized indexen than to have colliding txn or "limited to x bits" txn count.
mircea_popescu points out wholly disinterestedly at this point that the eponymous mpfhf allows for variable length output, and could be made to do say log (blockheight) bits!
mircea_popescu: well you'rte going to start getting collisions way before you used up every possible txid
mircea_popescu: asciilifeform that means there's a cap on total txn bitcoin will ever process
mircea_popescu: other than the hope "they won't be many" (recall the naive oh, if we need we just add more digits after decimal ? hurr. you fucking don't.)
mircea_popescu: and what is meant when people such as me say bitcoin's a pos and what it was meant when i told the power ranger tards to fix it or get killed years ago
mircea_popescu: this is at the core of the argument in favour of a trb-i implementation.
mircea_popescu: they in principle became impossible at some point once people figured out this hole.
