Secure and decentralized sidechain achieving consensus for public or private blockchains

摘要

Sidechain secure and decentralized achieving consensus for public or private blockchains. The invention relates to a sidechain system allowing the achievement of one or more consensus for digital assets characterized in that it is secure and decentralized and communicates with a main blockchain, public or private, using a protocol, named Meerkat, making it possible to achieve one or more consensuses, and in that it includes a Bank entity comprising one or more banks, ensuring the storage of digital assets and users, an Executor entity, comprising one or more processors, each processor ensuring the realization of business processes, a validator entity comprising validators who validate the proof that each action of a user has indeed been carried out by him, said system ensuring the authentication of each user through a system of shared signatures between the participating networks, the system further comprises one or more containers, allowing the sharing of signatures, said con tainers being signed by the user and contain one or more vouchers, said vouchers containing the addresses, data and parameters of banks, processors and validators, in order to execute one or more contracts on the user's digital assets . Meerkat protocol validates the progress of the exchange of digital assets on the main blockchain. The invention further relates to the method implemented in the system as well as the use of the sidechain system in an auction and in systems using blockchain technology.
