<a​ioghaosdihfaowie:matrix.org> Hi, how do I derive public spend/view key from private spend/view key?

sech1: oh, right, I think I screwed up my program :)

just checked with zmq-cli and you are right

is there a way to get the target height on the pub-sub interface?

<j​effro256:monero.social> for which type of address? (main, subaddress)

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

i.e: Height: 1141, target: 1617549 (0.0705388%)

or in the output when running monerod in a terminal: 2024-06-07 05:22:36.128I Synced 7841/1617549 (0%, 1609708 left)

i want to get the 1617549 figure

<j​effro256:monero.social> sorry was replying to @aioghaosdihfaowie

oh haha, that makes more sense

xbjfk you need to subscribe to "json-full-chain_main" or "json-minimal-chain_main" ZMQ messages to get each block

or "json-full-miner_data" to get current target height. You can check P2Pool's zmq_reader.cpp for reference

sech1: hmmm, i can't seem to find the target height in any of those (only current height)

I can't find any mention of "target" in zmq_reader.cpp too

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":[]}

here's an example of what I get for miner_data

"height"

you need to wait until your node is fully synced

oh, yeah - sorry I should've specified I want *target* height (I want to display sync progress)

so, presumably no way to do that via the zmq pub interface?

No at this moment

*Not

you could get target height via a regular RPC call and poll it periodically

right, thank you :)
