15:04:04 <wowario> we've open a bounty to implement miner template signing as part of the PoW https://funding.wownero.com/proposal/67
15:04:58 <wowario> idea was proposed last year by tevador and SChernykh
15:05:15 <wowario> https://git.wownero.com/wownero/meta/issues/28#issuecomment-1030
15:06:10 <wowario> wownero has a problem with pool centralization
15:07:10 <wowario> top 2 pools accounts for 70% network hash https://miningpoolstats.stream/wownero
15:07:17 <wowario> based in China
15:08:01 <moneromooo> Who doesn't :/
15:08:48 <sech1> "Sign the block header using the secret spend key from the coinbase transaction"
15:08:55 <sech1> then how do other nodes check the signature?
15:15:53 <jwinterm> sech1 is hirred
15:15:58 <jwinterm> hired
15:17:01 <jwinterm> I guess would need to include coinbase receive address in tx extra or something?
15:21:54 <wowario> maybe same as signing/verifying a message with a private key
15:23:24 <jwinterm> right but normally the coinbase receiving address isn't exposed in the coinbase tx
15:23:38 <jwinterm> so no one would have the public key to verify that the signature was correct
15:23:50 <jwinterm> I think
15:24:16 <sech1> receiving address is a stealth address
15:25:53 <wowario> doesn't a standard address include a public spend and view key
15:27:08 <wowario> https://monerodocs.org/public-address/standard-address/
15:27:57 <jwinterm> yes but standard address isn't exposed in coinbase tx
15:28:01 <jwinterm> only a stealth address
15:28:27 <jwinterm> so we'd have to add a place for miner to include their address, like it would be required in tx extra or something
15:28:44 <wowario> yeah
15:28:57 <wowario> think so
15:30:16 <wowario> mechanics hasn't been fully thought through
15:40:13 <sech1> so miner must provide: a receiving address (public spend/view keys), private view key to prove that this transaction goes to that address, and also sign the entire block header with his private spend key
15:40:29 <sech1> public spend key (which is part of an address) can then be used to check the signature
15:41:42 <sech1> It probably makes sense to get rid of stealth addresses for coinbase transactions because full receiving address must be there anyway
15:44:17 <sech1> so replace stealth address with normal address for coinbase transactions and sign block header with private spend key. No need to publish private view key.
15:45:22 <wowario> pools could still be possible, but all miners would have access to private spend key
15:47:33 <sech1> we discussed it already. Each miner gets their unique address and mines to it. Miner can of course steal mined block, but a safety deposit (=single block reward) to the pool will be required to start mining
15:48:39 <moneromooo> I fear only large miners will be able/willing to afford this, and small miners with just not mine.
15:50:08 <NickvanSaberhagn> It’s creative and interesting tho! I can contribute!
15:51:23 <wowario> how scalable would it be to manage deposits and check miners haven't stolen blocks
15:52:07 <wowario> at some point cost vs benefit wouldn't make sense for large scale mining pools
15:52:15 <sech1> pool will have to run 1 wallet per miner and move all mined blocks to the pool's hot wallet
15:54:15 <sech1> some custom code that checks each block against known wallet addresses will be much lighter (since coinbase addresses will be public)
15:54:30 <sech1> pool sees some miner's address -> launches appropriate wallet -> moves funds
16:20:07 <sech1> template signing would also make dev fee mining impossible, hmm...
16:20:23 <gingeropolous> oh NOES!
16:21:35 <wowario> lol
16:22:12 <sech1> it's always possible to switch to another coin for dev fee though
