Jito Labs launches Block Assembly Market BAM: Enhancing Solana execution transparency and fairness

According to Wu, Solana's MEV infrastructure Jito Labs published an article introducing its launched Block Assembly Marketplace (BAM), claiming it can address the pain points of the Solana network, consolidate on-chain advantages, and support the realization of the “Internet Capital Market.” The article points out that BAM can ensure transparent and fair execution on Solana, promoting on-chain transactions to surpass centralized venues; it analyzes the current execution uncertainty problem on Solana caused by seven different transaction schedulers; it explains that the construction of BAM is to learn from the bad incentive lessons of Ethereum's proposer-builder separation (PBS) to avoid repeating the same mistakes. BAM achieves application control execution (ACE) through a plugin system, addressing the insufficiency of FIFO ordering; regarding security and decentralization, it relies on a Trusted Execution Environment (TEE) to ensure verifiable transaction settlement, and explains its safety from the perspectives of physical security and confidentiality. In the future, BAM plans to open source its code, expand ACE, decentralize operators, achieve collaborative block construction, and accelerate through FPGA hardware.
