There doesn't seem to be an answer to this question anywhere. Geth shows I mined an uncle. There's all kinds of discussions about what/where/and how uncles exist, but when does the miner get paid?
An uncle block only exist as such when it is incoraped in a regular block.
A uncle miner is paid immediately when a regular block includes it.
Perhaps with an example is more clear
- blocks A100 and B100 are found at heigh 100
- block A101 is mined on top of A100
- block A102 includes B100 as uncle
Miner from B100 will be credited after block A102 is mined.
