Power_blockchain is a distributed ledger platform for high-speed processing of interactions in decentralized single address space. In contrast to many classic platforms, Power_blockchain is a platform for general purpose interactions processing and is not limited to such applications as value transferring or smart contracts. Power_blockchain attains high-speed processing by means of horizontal scaling of the internal distribution of interactions processing solutions to dedicated blockchain subsystems - shards, in parallel. According to trilemma, scalable projects usually have security or decentralisation problems, and consequently, it considered as private (permissioned) platforms, as Hyperledger Fabric, BigchainDB. However Power_blockchain platform is developed to utilize all conditions in the trilemma. The basis of Power_blockchain is three-layer architecture, which allows to be public (permissionless) platform solving scaling problems: Management layer is responsible for decentralization Sharding layer solves the scalability problem Validators layer provides a high degree of security Because of the use of multidimensional (multilayer) blockchain management system own algorithm of consensus Resonance has been developed. It’s utilized within shards (Sharding layer), while enabling nodes to interact under two other layers.
