The Stake Action

NFT: locked.

Note: The stake action code be found here.

This action adds an entry to the active entries of the reward distributor. The entry immediately starts earning rewards in the active epoch, and has a corresponding share of 1.

The action asserts that an NFT is locked with the p2_singleton inner puzzle by using a settlement payments announcement. To prove the NFT belongs to a collection, a proof is used to calculate the launcher id starting with the minter DID inner puzzle hash (and going through all the intermediary coins).

The action also creates a puzzle announcement that be asserted to ensure the dApp singleton is running the right action with the right parameters. For the stake action, the announcement prefix, s, is concatenated to the offer announcement hash (i.e., the settlements payments announcement is 'reflected' by the reward distributor).
