The invention discloses a contract trigger method and device based on a block chain. The method comprises steps that the transaction information of a transaction presently processed by a block and relevant to a contract is acquired, wherein the contract comprises the identifier information of the transaction, and the transaction information comprises the transaction number and the total amount information; according to the number and the total amount information, whether the presently-accomplished transaction is the last one is determined; if yes, the contract is triggered. The method is advantaged in that the contract itself can be spontaneously triggered.
