decimation

yeah if it's the last file, it's incomplete

[00:00]

asciilifeform

aha

[00:00]

mod6

these were fully sync'd up to ~320`000 blocks or so. they were shutdown after full sync was achieved. each goes upto like blk0017.dat

[00:00]

mine stops at blk0008.dat

[00:01]

on a fully sync'd node?

[00:01]

whats the full size of your blockchain? mine's like ... ~38Gb

seems to diverge for me starting with blk0008.dat

^^^ from my box circa 2013 !

[00:06]

mod6

huh. yours dont match ours or mps

[00:07]

asciilifeform

with ecc ram, no less

[00:07]

asciilifeform

and raid5

[00:07]

asciilifeform

(the latter with nightly parity checks!)

[00:07]

decimation

with orphans?

[00:09]

asciilifeform

almost certainly

[00:09]

asciilifeform

(for the same reason as mircea_popescu's)

[00:09]

asciilifeform

they were moved from an earlier disk, where the thing was going from late 2010

[00:10]

asciilifeform

iirc

asciilifeform observes that the 'eater' has completed blk0001

[00:14]

asciilifeform

is presently past 189070

[00:15]

asciilifeform

anomaly has not recurred yet

[00:15]

asciilifeform

(but is not expected for a while)

[00:15]

asciilifeform

sha256(blk0001.dat) is equal to the expected value.

[00:18]

asciilifeform

mod6: where are the 3rd items in these triples from ?

[00:18]

asciilifeform

anything peculiar about that node ?

[00:19]

mod6

so one of them seems to be more screwed up than the others. but there were blocks like blk0009.dat & 10 where all were different.

[00:20]

mod6

one was done in january, one in february, and one in march.

[00:20]

mod6

january was pre SSL 1.0.1g

[00:20]

asciilifeform

this is probably when i say that it will be necessary to walk the blocks.

[00:21]

asciilifeform

and compare individual ones

[00:21]

assbot

[MPEX] [S.MPOE] 11300 @ 0.00046595 = 5.2652 BTC [+]

[00:23]

mod6

yeah, totally agree.

[00:25]

mod6

im suprised they diverged that much.

[00:26]

mod6

i would have though with all the same version (pretty much) that they would have all been the same hashes.

[00:26]

asciilifeform

~recent~ syncs diverging is almost certainly a product of enemy fire

[00:26]

mod6

glad I looked at that

[00:26]

assbot

[MPEX] [S.MPOE] 64550 @ 0.00048971 = 31.6108 BTC [+] {3}

[00:27]

decimation

yeah, gotta take it block by block

[00:27]

decimation

the question is, how do we make a portable tool to suck blocks from bitcoin nodes?

[00:30]

decimation

something that parses .dat files?

[00:30]

asciilifeform

decimation: one way is what i'm doing

[00:30]

asciilifeform

but it's a bit slow

[00:30]

decimation

yes true

[00:30]

asciilifeform

there is a python thing floating around, iirc

[00:30]

asciilifeform

can try that.

[00:30]

asciilifeform

alternatively, write own (format is pretty simple)

[00:30]

mod6

yah, there's asciilifeform's way, and there's that python thing

[00:30]

asciilifeform

alternatively wait for me, but i'm up to my ears in backlog of work

[00:31]

asciilifeform

where the hell is mircea_popescu

[00:33]

asciilifeform

at this rate, he's gonna miss ragnarok.

[00:33]

asciilifeform

(then again, this ragnarok will still be there tomorrow..)

[00:34]

phf

fwiw dumpblock is expensive, because walks blockchain in order. a "dumpdb" that iterates over mapBlockIndex and does ReadFromDisk/js in 5-10 months, so everything i know is probably stale

[03:23]

ben_vulpes

funkenstein_: "hammered"?

[03:24]

trinque

ben_vulpes: yeah you can use reagent in this manner

[03:24]

funkenstein_

like, ddosed

[03:24]

trinque

wanted to know if the native thing would eat clojurescript, in case I end up having to use it

[03:24]

BingoBoingo

like, ddosed While I was away from the computer when Rassah finally stopped derping about "escrowless" escrow and his 1,000 BTC Prius and got down to business, here's what transpired when he did. bootstrap.dat

[20:09]

jurov

when later i got my hands on perma connection, UO's star faded or whatever
