we've open a bounty to implement miner template signing as part of the PoW funding.wownero.com/proposal/67

idea was proposed last year by tevador and SChernykh

wownero has a problem with pool centralization

top 2 pools accounts for 70% network hash miningpoolstats.stream/wownero

based in China

Who doesn't :/

"Sign the block header using the secret spend key from the coinbase transaction"

then how do other nodes check the signature?

I guess would need to include coinbase receive address in tx extra or something?

maybe same as signing/verifying a message with a private key

right but normally the coinbase receiving address isn't exposed in the coinbase tx

so no one would have the public key to verify that the signature was correct

I think

receiving address is a stealth address

doesn't a standard address include a public spend and view key

yes but standard address isn't exposed in coinbase tx

only a stealth address

so we'd have to add a place for miner to include their address, like it would be required in tx extra or something

yeah

think so

mechanics hasn't been fully thought through

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

public spend key (which is part of an address) can then be used to check the signature

It probably makes sense to get rid of stealth addresses for coinbase transactions because full receiving address must be there anyway

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.

pools could still be possible, but all miners would have access to private spend key

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

I fear only large miners will be able/willing to afford this, and small miners with just not mine.

It’s creative and interesting tho! I can contribute!

how scalable would it be to manage deposits and check miners haven't stolen blocks

at some point cost vs benefit wouldn't make sense for large scale mining pools

pool will have to run 1 wallet per miner and move all mined blocks to the pool's hot wallet

some custom code that checks each block against known wallet addresses will be much lighter (since coinbase addresses will be public)

pool sees some miner's address -> launches appropriate wallet -> moves funds

template signing would also make dev fee mining impossible, hmm...

oh NOES!

lol

it's always possible to switch to another coin for dev fee though
