15:31:03 <kico> hey guys where can we get information on reorgs? how deep can they be and how many we get?
15:31:06 <kico> thanks in advance
15:31:42 <kico> for a project that is considering merge mining
15:48:45 <sech1> Only see 1-2 block deep reorgs in the logs
15:48:53 <sech1> more than 3 blocks is extremely rare
15:49:37 <kico> per day you mean?
15:49:41 <kico> thanks sech1 
15:50:13 <sech1> no, since I started keeping logs :D
15:50:24 <kico> hahah fair enough
15:50:26 <sech1> 1 block deep reorgs happen every day
15:50:34 <kico> this is no compiled anywhere right?
15:50:36 <sech1> 2 blocks, maybe once every few days
15:50:47 <sech1> 3 blocks happened 1 or 2 times in a few years
15:52:27 <kico> I see
15:52:31 <kico> thanks a bunch sech1 
16:18:48 <moneromoooo> alt_chain_info in monerod will tell you what reorgs your node has seen.
16:19:35 <nioc> kico: ^^
16:20:08 <kico> awesome thanks guys :)
16:46:31 <sech1> but only since the node has started
16:47:51 <sech1> https://paste.debian.net/hidden/9a87ffc4/
16:48:00 <sech1> this is on a node with 54 days uptime
16:48:46 <selsta> i have seen a couple 2 block deep reorgs recently on some of my nodes
16:48:50 <selsta> but never 3 blocks
16:49:31 <sech1> I've checked my older logs and found only a single 3 blocks reorg
16:49:38 <sech1> in April 2021
16:52:57 <selsta> hmm, alt_chain_info shows 1 block deep
16:53:58 <selsta> (ignore my comment about 2 block deep reorgs from above)
16:55:57 <sech1> yes, I also can find "alternative blockchain size: 2" in the log, but it shows up as 1 block deep in alt_chain_info 
16:56:08 <sech1> which means then single "alternative blockchain size: 2" is acutally 2 blocks deep
16:56:20 <sech1> *alternative blockchain size: 3
16:56:24 <selsta> yes
17:01:03 <moneromoooo> It's not supposed to wipe those when it starts. If you see a bug there, feel free to fix.
17:02:14 <selsta> I think it should wipe them without `--keep-alt-blocks`
17:02:56 <moneromoooo> Oh you're right, my monerod is running with that indeed :D
