1 2016-06-18 00:37:29 <Aridmango> i upgraded from 0.8.1 to most recent version and now my blockchain needs to be rebuilt. debug log says my blk00129.dat is missing from data folder but i was completely up to date... any ideas?
 2 2016-06-18 01:21:23 <luke-jr> Aridmango: #bitcoin but I don't see the problem
 3 2016-06-18 03:06:46 <midnightmagic> This channel should probably go away with a month-long redirect to #bitcoin and then disappear altogether. :-/
 4 2016-06-18 03:27:28 <kadoban> Why'd it ever move to #bitcoin-core-dev or whatever it is anyway?
 5 2016-06-18 05:09:22 <Vainglory> i'm trying to create my own checkpoints.txt file for bitcoin-wallet on android - is there a how-to for this?
 6 2016-06-18 06:46:09 <wumpus> kadoban: to reduce the scope to something manageable
 7 2016-06-18 06:46:48 <kadoban> Wasn't that already the scope of this channel though?
 8 2016-06-18 06:46:53 <wumpus> no
 9 2016-06-18 06:50:24 <wumpus> bitcoin-core-dev has a much narrower focus: just discusion of day-to-day development involving bitcoin core. This channel also includes network-wide issues. In any case this channel became too noisy.
10 2016-06-18 17:54:09 <Vainglory> Is there a how-to on creating a checkpoints file?
11 2016-06-18 18:12:59 <arubi> Vainglory, I'm not sure I understand you question, but if you `git grep` for 'checkpointData = (CCheckpointData)', it might have a few hints
12 2016-06-18 18:13:07 <arubi> your*
13 2016-06-18 18:15:35 <Vainglory> arubi: that's not coming up with anything for bitcoinj or bitcoin-wallet
14 2016-06-18 18:16:33 <arubi> well, try bitcoin core
15 2016-06-18 18:19:37 <arubi> Vainglory, an actual checkpoint at height 11111 is 0x0000000069e244f73d78e8fd29ba2fd2ed618bd6fa2ee92559f542fdb26e7c1d, maybe that'll return results with different software
16 2016-06-18 18:20:06 <Vainglory> arubi: well, i'm trying to figure out the actual formula used for checkpoints
17 2016-06-18 18:20:18 <arubi> what do you mean by formula?
18 2016-06-18 18:21:58 <Vainglory> i'd like to put my own checkpoints in, and i'm trying to find out how to create my own. trying to see how the checkpoints are generated, what the algorithm/formula is that's used to create something like 0x0000000069e244f73d78e8fd29ba2fd2ed618bd6fa2ee92559f542fdb26e7c1d for 11111
19 2016-06-18 18:24:07 <arubi> this is how core does it, apparently: https://github.com/bitcoin/bitcoin/blob/master/src/chainparams.cpp#L133
20 2016-06-18 18:25:04 <arubi> see there are 3 occurrences of 'checkpointData = (CCheckpointData)', and the structure is the same
21 2016-06-18 18:28:42 <Vainglory> arubi: that's a considerably different format. https://github.com/bitcoin-wallet/bitcoin-wallet/blob/a18dae250a1a6f1e69d67a50684bd144e80ea1cb/wallet/assets/checkpoints.txt
22 2016-06-18 18:36:50 <arubi> Vainglory, yep, it is.  but I never looked at bitcoin-wallet before so I wouldn't know
23 2016-06-18 20:31:17 <maaku> can someone make it rain? mvxLXr6YXtz7nVg1NsEuxcQMQTyoSKXsCz
