“Looking at the technical white paper, the ideas are simply advanced like black technology.” The Rolls of Bitlayer V2 is built on a major premise: provable security of the BTC mainnet + high-performance L2 smart execution. It employs a BitVM hybrid verification mechanism—combining zk proofs + a challenge mechanism (optimistic fraud proofs), with a post-release challenge period to prevent cheating.
It also designs a dual-layer consensus structure: PoS rapid block production ensures second-level soft finality for on-chain transactions, and then archives them to the BTC main chain through Rollup to achieve hard finality. During the challenge period, fraud detected can result in the forfeiture of collateralized BTC when Rollup cannot deceive.
On the other hand, it features a configurable secure exit mechanism (Escape Hatch) and optional data availability solutions, providing more reliable protection for user assets.
Overall, this is a clearly structured, complete Bitcoin L2 design that balances performance, security, and compatibility, laying a solid foundation for future large-scale financial applications.
