Thu Mar 17 00:07:28 UTC 2016 <mircea_popescu> my modeling shows it'd be way the fuck cheaper to calculate nonce blocks than to try and churn merkel trees
Thu Mar 17 00:06:04 UTC 2016 <mircea_popescu> jurov how ? his hash2 won't change.
Thu Mar 17 00:05:14 UTC 2016 <mircea_popescu> but, obviously - the more moving parts, the more problems.
Thu Mar 17 00:05:06 UTC 2016 <mircea_popescu> mod6 it's not entirely impossible to make the shifting a function of difficulty differential (note that there isn't a rule BOTH hashes have to be under THE SAME number. if there's two numbers, you could have an equalizer algo that does the shift moving)
Thu Mar 17 00:04:14 UTC 2016 <mircea_popescu> knob 1 above decides whether to obsolete current miners entirely or just partially, and is a [true] soft vs hard fork ; knob 2 decides how much i/o pressure to put on relay nodes ; knob 3 decides how much relay work to require in the mix.
Thu Mar 17 00:03:15 UTC 2016 <mircea_popescu> and yet another twistable knob exists : the nonce may be shifted before taking the nonceth element.
Thu Mar 17 00:02:26 UTC 2016 <assbot> The necessary prerequisite for any change to the Bitcoin protocol on Trilema - A blog by Mircea Popescu. ... ( http://bit.ly/1S52R51 )
Thu Mar 17 00:02:25 UTC 2016 <mircea_popescu> see footnote 2, example : http://trilema.com/2016/the-necessary-prerequisite-for-any-change-to-the-bitcoin-protocol/#footnote_1_64828
Thu Mar 17 00:01:57 UTC 2016 <mircea_popescu> N is another twistable knob. can be 1, can be whatever.
Thu Mar 17 00:01:45 UTC 2016 <mircea_popescu> out of every Nth preceding block, the nonce-th byte is put in a string ; the combine hashed.
Thu Mar 17 00:00:49 UTC 2016 <mircea_popescu> jurov the digest from past blocks is done like so :
Thu Mar 17 00:00:39 UTC 2016 <mircea_popescu> this is a twistable knob.
Thu Mar 17 00:00:35 UTC 2016 <mircea_popescu> it does. i specifically left the "hashing" undefined. it can be defined so both use sha3. or first stays as is and 2nd sha3. etc.
Wed Mar 16 23:58:06 UTC 2016 <mircea_popescu> word ?
Wed Mar 16 23:58:05 UTC 2016 <mircea_popescu> ok. so currently, for every block being mined : a header is calculated ; to this a nonce is added, the combine hashed. the resultant hash has to be smaller than a number to qualify as a found block.
Wed Mar 16 23:56:42 UTC 2016 <mircea_popescu> maybe it'd benefit from a going over once more.
Wed Mar 16 23:56:32 UTC 2016 <mircea_popescu> dja understand the amended form we came to well ?
Wed Mar 16 23:56:19 UTC 2016 <mircea_popescu> jurov quite so.
Wed Mar 16 23:55:56 UTC 2016 <mircea_popescu> too bad i constantly strangle the easy fruit pickers. if only they fucking picked in THAT direction ffs.
Wed Mar 16 23:55:32 UTC 2016 <mircea_popescu> but possibly there's other easy fruit to pick
