s101, acquiring transaction information created by a transaction party, and correspondingly generating a transaction block.
In a specific application, transaction information created by transaction parameters input by a transaction party through a display device of the transaction party is acquired, and a transaction block is correspondingly generated according to the transaction information and used for storing the transaction parameters, wherein the transaction parameters can include but are not limited to transaction amount, transaction quantity and transaction time limit.
S102, acquiring first voting data of all users, and acquiring a voting result of a witness according to the first voting data; wherein the all users include the transaction party and the witness.
In a specific application, first voting data of voting of all users through display equipment of all users are obtained, voting results of witnesses needed for a transaction are obtained according to the obtained first voting data, and the first voting data comprise voting data which are set to be equal to or less than the number of all users within voting time according to actual conditions. Wherein all users include trading parties and witnesses and other users in the current blockchain. The witness refers to a user who is elected by a witness voting mechanism among all users and verifies the transaction information of the current transaction.
S103, obtaining the number of witnesses determined by a transaction party in a preset proportion, and determining the number of witnesses the same as the number of the witnesses according to the voting result and the number of the witnesses.
In the specific application, the number of required witnesses for the current transaction is determined by acquiring transaction parties with a preset proportion, which users are witnesses of current transaction information in all users are determined according to the voting result of the acquired first voting data and the number of the required witnesses for the current transaction, and the number of the determined witnesses is the same as the number of the required witnesses for the current transaction determined by the transaction parties with the preset proportion. The preset proportion is the proportion of the transaction parties which determine the number of witnesses in all the transaction parties of the current transaction information according to the requirements set by actual conditions. Typically, the predetermined ratio is set to be greater than 50%.
And S104, acquiring authentication information in an authentication block corresponding to the witness.
In a specific application, the authentication information included in the authentication block corresponding to the determined witness is acquired and used for authenticating the current transaction information. The authentication block refers to a block created by the prover for authenticating the transaction information, and includes but is not limited to authentication information.
