Claims (70)

1 . A registration method of a timed smart contract in a blockchain, comprising:

receiving a registration request of the timed smart contract; and

when a lookup request of a trusted node or other trusted oracle in the blockchain is received, providing the log to the trusted node or the other trusted oracle; and

according to a lookup result, verifying whether the time information recorded in the log is accurate or not,

if not, marking the trusted oracle as being un-trusted and re-executing a step of electing the trusted oracle from the plurality of oracles.

7 . The execution method of the timed smart contract in the blockchain according to claim 4 , further comprising:

setting a transaction block for a non-timed smart contract, wherein a transaction corresponding to the other smart contracts is recorded in the transaction block; and

further comprising: for the timed smart contract, setting a built-in block or a built-in region in a transaction block; and configuring a corresponding amount of consumable resources to the built-in block or the built-in region, wherein the built-in block or the built-in region records a transaction corresponding to the timed smart contract, and

executing the timed smart contract comprising:

when an execution trigger of the timed smart contract is received, judging whether an amount of resources currently required is not greater than the amount of consumable resources corresponding to the built-in block or the built-in region or not, if yes, executing the built-in block or the built-in region corresponding to the timed smart contract, and if not, forbidding execution.

9 . The execution method of the timed smart contract in the blockchain according to claim 4 , wherein
