Embodiment Construction

[0066] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments . Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0067] In the Bitcoin network, from the perspective of transaction generation and packaging verification, nodes can be simply divided into sending nodes and receiving nodes. In the Bitcoin system, sending nodes are users who submit transaction information. If there is a new transaction to submit , then the sending node will broadcast the transaction information on the Bitcoin network. The receiving node has been monitoring whether there is...

Abstract

The embodiment of the invention relates to the technical field of block chains, in particular to a transaction method and device based on a UTXO model, and is used for saving network resources occupied by transaction data. The method comprises the steps of determining that a transaction comprises N unspent transaction outputs, wherein N is greater than 0; creating data of the transaction; whereinthe data of the transaction comprises a transaction identifier; wherein the verification array comprises verification information of unspent transaction output, the transaction input and / or the transaction output comprises a verification index of the unspent transaction output, and the verification index marks the position of the verification information of the unspent transaction output in the verification array; and broadcasting the data of the transaction.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a transaction method and device based on a UTXO model. Background technique [0002] Blockchain (Blockchain) is an important concept extracted from Bitcoin. It is essentially a disintermediation database. At the same time, as the underlying technology of Bitcoin, it is a series of data blocks that are associated using cryptographic methods. Each data block contains the information of a Bitcoin network transaction, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block. In a narrow sense, the blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be tamper-proof and unforgeable distributed ledgers. Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus alg...
