Abstract

The invention discloses a transaction method and device based on a block chain UTXO model, and relates to the technical field of block chains. A specific embodiment of the method comprises: creating a transaction public address of a UTXO model on a main chain of a block chain, wherein the transaction public address is used for storing a UTXO transferred by a user; receiving a UTXO transaction request sent by the user, wherein the transaction request is used for performing transaction operation on the UTXO stored in the transaction public address; and carrying out transaction accounting through the accounting node of the side chain of the block chain so as to carry out transaction operation. According to the implementation mode, rapid and frequent transaction between users on the block chain taking the UTXO as the transaction model can be realized, the user transaction efficiency is greatly improved, the security of the system is ensured, trust is established in the network, and the normal operation of the system is ensured.

Description

technical field [0001] The present invention relates to the field of block chain technology, in particular to a transaction method and device based on a block chain UTXO model. Background technique [0002] The latest FastPay expansion solution is proposed in Libra, a cross-border payment project led by Facebook, which can support efficient distributed accounting and greatly speed up transactions. Or traditional settlement systems such as mastercard. However, in the Libra system, the FastPay solution is based on the account model, and the current transaction model of some digital currencies is the UTXO (Unspent Transaction Outputs) model, such as Bitcoin, which makes the current FastPay solution not fully applicable. Contents of the invention [0003] In view of this, the embodiments of the present invention provide a transaction method and device based on the UTXO model of the blockchain, which can realize fast and frequent transactions between users on the blockchain wi...
