13:11:05 <br-m> <norgaard:matrix.org> Hello anyone who has knowledge on crypto transaction should message me for a huge crypto deal
16:38:24 <br-m> <n3osat_s:matrix.org> Hello World of cypher, what's your advise for a Bitaxe or a NerdQuaxe ? Thks
16:41:20 <br-m> <plowsof:matrix.org> n3osat_s this is a room reserved for "has joined" , "has left" messages only, please take this question elsewhere, monero has no asics 
17:03:10 <Cindy> how possible is it to use the monero blockchain to timestamp hashes
17:03:30 <Cindy> like make a transaction to myself but with a batch of hashes added to tx_extra
17:30:28 <br-m> <n3osat_s:matrix.org> @plowsof:matrix.org: I mean : any stuff equi for XMR mining ?
17:30:36 <DataHoarder> CPUs.
17:31:41 <Cindy> i just wonder if opentimestamp can be extended to XMR
17:31:43 <sech1> Cindy https://github.com/monero-project/monero/pull/8733
17:31:44 <DataHoarder> Cindy: yeah, though preferably not used that often. have a commitment in extra data, not even batch. a merkle root, to keep it compact
17:32:02 <sech1> it's generally discouraged to use tx_extra for arbitrary data
17:32:18 <sech1> aka for NFTs
17:33:58 <Cindy> DataHoarder: ah yeah, merkle trees
17:34:33 <DataHoarder> same way it's done already for megre mining
17:35:06 <Cindy> sech1: i'm not gonna vandalize the blockchain lol
17:35:46 <sech1> Adding data to tx_extra is not supported officially, so you'll have to write your own code and probably modify wallet2.cpp too
17:36:26 <Cindy> DataHoarder: if all we're putting is a root hash in the transaction, where would we store the tree in?
17:36:47 <Cindy> probably in a centralized database
17:36:49 <DataHoarder> no need to store full tree
17:37:03 <DataHoarder> merkle proof contains the data to check
17:37:09 <DataHoarder> it's a couple of hashes, + data (hash of data proven) itself
17:37:33 <DataHoarder> if you are only proving a single piece of data, merkle root = hash(data)
17:38:33 <Cindy> oh yeah the timestamp file
17:38:40 <Cindy> smh i forgot
17:38:46 <Cindy> i have never used opentimestamp
17:39:39 <DataHoarder> on a different topic: https://blocks.p2pool.observer/block/f58aafd20fc914881d6e342721c4a4451fe6ac707afd7d3ed5bed080b12be5e9
17:39:49 <DataHoarder> someone likely using p2pool as backend for their own pool or solo mining
17:40:44 <Cindy> unofficial p2pool chains
17:40:52 <DataHoarder> what is "official" :D
17:40:57 <Cindy> yaaay
17:41:03 <DataHoarder> pools get created and later added to defaults
