Problems solved by technology

However, this method of time marking is obviously unreasonable, because the computers involved in the transaction may be in different time zones
In addition, even if the computers participating in the transaction are in the same time zone, the local time of the computer may not be synchronized with the server, which will cause the transaction time recorded by the transaction parties to be different
This time difference brings a very big security threat to the security of the transaction

Abstract

The invention relates to a method for determining a transaction time of a block chain off-chain transaction. The method comprises the steps in which, an initiator participating in an off-chain transaction generates a bill secret key based on bill information of the current block chain off-chain transaction; the initiator generates a bill secret key hash value of the current block chain off-chain transaction based on the bill secret key; the initiator sends the bill secret key hash value to a responder; the responder initiates a contract transfer associated with the current block chain off-chain transaction according to the bill secret key hash value, and the block chain height of the responder when the contract transfer occurs is taken as the pre-registered transaction time of the current block chain off-chain transaction; when receiving the transfer information related to the contract transfer from the responder, the initiator verifies the transfer information; and when determining that the transfer information is correct, the initiator determines the pre-registered transaction time as the contract transaction time and sends the transfer information including the contract transaction time to a server.

Description

technical field [0001] The present invention relates to the field of block chain technology, and more specifically, to a method and device for determining transaction time of transactions outside the block chain. Background technique [0002] The off-chain transaction network of the blockchain is an extension of the blockchain node network. The core protocol of the off-chain transaction network is an agreement for the transfer parties to use smart contracts to realize massive and high-frequency transfers of one or more digital assets through a transfer channel without the participation of an intermediary. In the off-chain transaction network, two or more parties can participate in the transfer, which means that other nodes can participate in this transfer channel. The creation of each off-chain channel first requires an on-chain transaction. Lock an unspent transaction output UTXO (Unspent Transaction Output) funds on the chain as input. The output of this transaction is ...
