Would it be possible for miners to set an email address to get notified if they hit upon a block? Maybe they could add it via the website using a signed message from the address they are mining to? It would be helpful for miners who mine long-term without them needing to check their wallet everyday.
Solo has no database whatsoever so there is nothing to store such information and act upon it. I believe lots of web blockchain viewing services provide something for that. On the other hand expected block solves are rare at only about 1 every 2 weeks and I post every single one of them here so if you are subscribed to get email notification of new posts here and see the block count increase in the message topic, you know a block has been solved and can then check here or your wallet.
