Introducing BAM: A New Era for Block-Building on the Solana Network

BAM Launches to Transform Block-Building on Solana

On July 21, 2025, the Jito Foundation, in partnership with Jito Labs, officially announced the launch of the Block Assembly Marketplace (BAM), designed to revolutionize how blocks are constructed on the Solana blockchain. This innovative architecture aims not only to enhance performance but also to ensure fairness and transparency within the ecosystem.

A New Framework for Block Building

BAM brings forth a substantial transformation to the core market structure of Solana. It introduces a three-pronged approach to transaction handling and scheduling, which fundamentally changes how blocks are built. The approach consists of:
1. BAM Nodes: These nodes function as schedulers that utilize Trusted Execution Environments (TEEs). They serve as the backbone of the BAM ecosystem, securing transaction sequencing while preserving user privacy and maintaining verifiability.
2. BAM Validators: This group runs an updated client for Jito-Solana. They receive transactions from BAM Nodes and execute them according to the protocols laid out, thereby ensuring that operations remain efficient and reliable.
3. Plugins: These are programmable interfaces that allow developers, traders, and applications to connect with BAM Nodes. By enabling interaction with Solana transactions in innovative ways, developers can craft custom transaction sequencing logic, leading to new monetization avenues through Plugin fees.

Enhanced Transparency and New Revenue Streams

BAM is expected to alleviate issues related to Maximal Extractable Value (MEV), a problem often seen in blockchain operations where miners or validators manipulate transactions for profit. With BAM's focus on deterministic and privacy-preserving scheduling, the transaction pipeline on Solana becomes more transparent, creating auditable markets with execution assurances similar to traditional finance systems.

For traders, this means faster and fairer transactions. For developers, BAM opens doors to the creation of applications that require precise transaction execution, such as Central Limit Order Books (CLOBs) and perpetual contracts. Lucas Bruder, CEO of Jito Labs, expressed enthusiasm regarding the launch, highlighting BAM's potential to redefine application development within the ecosystem: "BAM opens up an entirely new design space for developers to build applications that weren't possible before."

Collaboration with Leading Validators

BAM is set to launch on Solana's mainnet shortly, with prominent validators including Figment, Helius, SOL Strategies, and Triton One, who will facilitate BAM transactions during the initial rollout phase. The expansive vision for BAM includes evolving it into a fully permissionless platform, with a community-driven approach to governance and development.

As the Solana network continues to position itself as the hub for internet capital markets, BAM will provide the vital decentralized coordination needed to support its ambitions. The future of block-building on Solana is not just about technological advancement; it is about creating an inclusive and rewarding ecosystem for all participants.

About the Jito Foundation

The Jito Foundation plays a crucial role in coordinating ecosystem initiatives and promoting the adoption of Jito's groundbreaking technologies. Through governance proposals and strategic partnerships, the Foundation empowers stakeholders to influence the evolution of Solana's decentralized infrastructure, ensuring that validators, stakers, and the wider community benefit from its growth.

Conclusion

With BAM, the Jito Foundation and Jito Labs are setting the stage for a transformative era on the Solana blockchain, marking significant progress toward a more transparent and equitable ecosystem. As BAM begins its operations, interested developers and users can learn more about how to get involved and capitalize on the opportunities presented by this pioneering platform.
