The trajectory to achieving a “full rollup” on Bitcoin is a gradual process, similar to that of Ethereum rollups gradually implementing fraud proofs/zk technology.
Build on Bitcoin (BoB) has taken the approach of building a product (on mainnet now) which resembles more of an hybrid optimistic rollup between Ethereum and Bitcoin L2. They have been quick to market and have built a strong community.
Despite the challenges, such as the complexity of building on Bitcoin compared to other ecosystems, BoB is set on making advanced features like zk and account abstraction available over time.
BoB’s approach tackles three major challenges: aligning with Bitcoin’s ecosystem, creating a real ecosystem of builders & apps, and ensuring liquidity for new projects. By leveraging both Bitcoin’s security and the Ethereum network, BoB is working to establish this balance.
But, this comes with tradeoffs which we thoroughly address in this presentation.
BoB’s journey is divided into several phases. Phase 1 which is already live is their optimistic Ethereum rollup. Phase 2 introduces Bitcoin PoW security through merge mining, while Phase 3 aims to transition to a Bitcoin rollup with fraud proofs (using BitVM) and potential ZK capabilities.
We also discuss their OptiMine protocol, which similar to PBS, separates block production from block finalization for allowing faster finality leveraging Bitcoin’s miners. This innovative approach ensures consistent block fees and enhances miner incentives for the longer term.
