the architecture of the B2 Network, focusing on the Rollup Layer and the Data Availability Layer. Here's a breakdown of the key components and their roles:Rollup Layer with ZK-Rollup: ZK-Rollup Adoption: B2 employs ZK-Rollup as the Rollup Layer. zkEVM Solution: The Rollup Layer adopts the zkEVM (Zero-Knowledge Ethereum Virtual Machine) solution, responsible for executing user transactions within the Layer-2 network and generating related proofs.Processing User Transactions: Users' t...
