| Originated of Contract_hash.t

A contract is simply an account on the blockchain ledger. There are two types of contracts:

implicit contracts represent accounts of users of the blockchain;
originated are special accounts with a Michelson script attached to them. Every time a transaction is sent to an originated account, its associated script is run in order to trigger some action in response.

An implicit account is identified by the hash of the public key which was used to create it. The owner of the corresponding private key is the holder of the account. An originated contract's hash is derived from its origination nonce (see below).

Originated contracts

type origination_nonce

Originated contracts handles are crafted from the hash of the operation that triggered their origination (and nothing else). As a single operation can trigger several originations, the corresponding handles are forged from a deterministic sequence of nonces, initialized with the hash of the operation.
