Description
Hyperchain enables users to create customizable blockchain systems with configurable throughput, transaction costs, staking parameters, validator requirements, and epoch settings. Through delayed Proof of Work, it periodically pins PoS hyperchain transaction histories to PoW pinning chains for enhanced security; the platform also supports chain creation, validator and delegator participation, and cross-chain æternity coin transfers through a bridge.Category: L1
