Looking for technical documentation on delegation for staking
Hello friends, does anyone know where I can find technical documentation on delegation? Maybe the type of documents a pool operator would use to configure the pool. In particular, I am interested in learning how Tezos wallet handles a spending key vs. staking key. In other words, it is my understanding the wallet retains the spending key such that funds can be moved out of the pool at any time. What does the wallet send to the staking pool? A signed delegation key?
