03:43:38 <m-relay> <a​ioghaosdihfaowie:matrix.org> Hi, how do I derive public spend/view key from private spend/view key?
04:15:15 <xbjfk> sech1: oh, right, I think I screwed up my program :)
04:15:31 <xbjfk> just checked with zmq-cli and you are right
04:17:13 <xbjfk> is there a way to get the target height on the pub-sub interface?
05:18:18 <m-relay> <j​effro256:monero.social> for which type of address? (main, subaddress)
05:22:24 <xbjfk> jeffro256:monero.social: im not entirely sure to be honest, I'm talking about the target block height you see when running eg monerod sync_status 
05:22:26 <xbjfk> i.e: Height: 1141, target: 1617549 (0.0705388%)
05:22:46 <xbjfk> or in the output when running monerod in a terminal: 2024-06-07 05:22:36.128I Synced 7841/1617549 (0%, 1609708 left)
05:23:08 <xbjfk> i want to get the 1617549 figure
05:25:39 <m-relay> <j​effro256:monero.social> sorry was replying to @aioghaosdihfaowie
05:28:00 <xbjfk> oh haha, that makes more sense 
06:13:04 <sech1> xbjfk you need to subscribe to "json-full-chain_main" or "json-minimal-chain_main" ZMQ messages to get each block
06:13:35 <sech1> or "json-full-miner_data" to get current target height. You can check P2Pool's zmq_reader.cpp for reference
06:16:50 <xbjfk> sech1: hmmm, i can't seem to find the target height in any of those (only current height) 
06:17:12 <xbjfk> I can't find any mention of "target" in zmq_reader.cpp too
06:18:32 <xbjfk> json-full-miner_data:{"major_version":1,"height":89017,"prev_id":"ba792ca9983eb540775c0baa225404cbcd82ccfb60d265422e6597aa8d6a0957","seed_hash":"10a16659ce5026db613b7879865a8fca7a2566d9dea30df68dd03a9dc8569d8c","difficulty":"0x1aaf52c8","median_weight":20000,"already_generated_coins":1467123123053321264,"tx_backlog":[]}
06:18:45 <xbjfk> here's an example of what I get for miner_data
06:23:57 <sech1> "height"
06:24:13 <sech1> you need to wait until your node is fully synced
06:29:38 <xbjfk> oh, yeah - sorry I should've specified I want *target* height (I want to display sync progress)
06:30:11 <xbjfk> so, presumably no way to do that via the zmq pub interface?
06:31:25 <sech1> No at this moment
06:31:27 <sech1> *Not
06:32:05 <sech1> you could get target height via a regular RPC call and poll it periodically
06:32:42 <xbjfk> right, thank you :)
