Abstract

The invention provides a lot wining method and terminal equipment based on a blockchain technology. The method comprises the steps of determining a lot-wining block according to a preset rule; adopting a Hash value stored by the lot-wining block as a lot-wining address, and generating a lot-wining factor according to the lot-wining address and the total number of times for drawing lots; extracting a preset number of lot drawing numbers and building a corresponding relation between the preset number of lot drawing numbers and a corresponding preset number of blocks which are generated before the lot-wining block, and binding each lot drawing number with the Hash value stored in the corresponding block; generating a lot-drawing factor of each lot drawing number according to the lot-wining address and the bound Hash value; determining the lot drawing number which wins lot according to the lot-wining factor and the lot-drawing factor of the lot drawing number. In this way, the authenticity of lot drawing data and the justice of a lot-drawing result are guaranteed.

Description

technical field

[0001] This application relates to block chain technology, in particular to a lottery method and terminal equipment based on block chain technology. Background technique

[0002] Blockchain is a new application technology collection of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. From a data point of view, the blockchain is a chained data structure that combines data blocks in a sequentially connected manner in chronological order, and the data structure is cryptographically guaranteed to be tamper-proof and unforgeable. From a technical point of view, blockchain technology integrates a variety of different technologies. By building a blockchain network, each node in the network is allowed to obtain a complete copy of the database, and based on the consensus mechanism and competitive computing. Maintain the update of the blockchain-based database, and thus realize the decent...
