Script-Hash Addresses

Script-hash Addresses are addresses that specify custom conditions under which funds can be spent from an address. The most common form of script-hash addresses are multi-key addresses, or multi-sig addresses. Multi-Key addresses specify multiple keys that can spend from the address and require one or more keys to authorize a transfer.
