Interface Store

protocol/protocol.go:73–81

Store provides storage for blockchain data: blocks and state tree snapshots. Note, this is different from a state snapshot. A state snapshot provides access to the state at a given point in time -- outputs and issuance memory. The Chain type uses Store to load state from storage and persist validat

// and issuance memory. The Chain type uses Store to load state
