Abstract

The embodiment of the present invention discloses a lottery method, device, system, equipment, and medium based on heterogeneous blockchains. According to preset business rules, the first blockchain is selected from all candidate blockchains; The first block chain sends lottery information; according to the first block value fed back by the first block chain, the second block chain is selected from the remaining candidate block chains. The first block value is calculated based on the lottery information and the transaction information of the block where the lottery information is located. Send the first block value and lottery information to the second block chain, and receive the second block value fed back by the second block chain. The second block value is calculated based on the first block value, the lottery information, and the transaction information of the block where the lottery information is located. When all candidate blockchains have been traversed, the lottery result is determined based on the block value fed back by the last blockchain. The serial generation of block values ​​based on multiple heterogeneous blockchains improves the credibility of lottery results.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to a lottery method, device, system, equipment and computer-readable storage medium based on heterogeneous block chains. Background technique [0002] Lottery software should pursue fairness as much as possible, and the results cannot be predicted or manipulated. The distributed ledger feature of the blockchain makes it non-centralized nodes and disperses control rights to the entire network. At the same time, the blockchain has the characteristics of anti-tampering and traceability, which can ensure the integrity of the data stored on the blockchain and has not been tampered with. These characteristics of the blockchain meet the needs of the lottery system. [0003] The overall implementation idea of ​​the blockchain-based lottery system in the prior art is as follows: first, the operator initiates the lottery at the lottery console; secondly, calculates a future blo...
