Bitroot is an independent Layer1 parallel public chain in the Bitcoin ecosystem, and the testnet is now live! It adopts a 'main chain + execution chain' architecture, separating consensus from execution. Dynamic sharding technology is introduced to adjust shards based on load. An asynchronous execution model is used, allowing independent transactions to be processed in parallel. With cross-chain interoperability protocols, it enables interaction with mainstream public chains. A hybrid consensus mechanism is utilized, balancing security and efficiency, theoretically achieving over 100,000 TPS and sub-second confirmation speeds, innovating in performance, security, and decentralization. #bitroot
