BAM revolutionizes Solana with the new Block Assembly Marketplace

Solana redefines block construction by announcing BAM, an infrastructure capable of transforming the sequencing and execution of transactions through transparent governance, protected privacy, and new programmable revenue opportunities for the entire ecosystem.

What is BAM and why does it change the rules of the blockchain on Solana?

Block Assembly Marketplace (BAM) represents a technological leap, developed by Jito Labs with the support of the Jito Foundation. The system primarily aims to ensure verifiable fairness and programmability in transaction management, addressing one of the most delicate issues: the prevention of harmful Maximal Extractable Value (MEV) that has often penalized small traders and reduced transparency in the crypto markets.

BAM uses a vertical network of hardware with Trusted Execution Environments (TEE), integrated with the existing validators of Solana, offering a secure and programmable alternative to the centralized logics of traditional finance. Thanks to BAM, auditable and guaranteed transaction pipelines become a reality, attracting the interest of developers, institutions, and retail traders.

How BAM works: the three pillars of the architecture

The BAM architecture is based on three interconnected components, each with strategic functions:

BAM Nodes: the heart of transparent sequencing

The network of BAM Nodes operates based on TEE: these schedulers work alongside the classic validators and manage the sequence of transactions in protected environments that combine privacy and verifiability, redesigning the syntax of the blockspace on Solana.

BAM Validators: aligned and updated execution

The Validatori BAM, who work with an updated version of the Jito-Solana client, implement the sequence decisions made by the BAM Nodes and increase computational intensity and security, bringing the blockchain closer to the standards of the most advanced financial markets.

Plugins: the gateway to monetization for developers

The Plugins represent a layer of programmability: developers, traders, and applications can interact directly with the BAM Nodes and monetize – through integrated fees – custom sequencing logic, sharing the revenues with the entire supply chain. In fact, a new redistribution of value among nodes, validators, and stakeholders is opened.

What advantages does BAM offer to traders, institutions, and developers?

BAM has been designed to bring tangible benefits to each segment of the Solana blockchain ecosystem:

• Trader: greater speed and fairness in execution, with processes comparable to the best CLOB (Central Limit Order Book) markets, including dark pool and perpetuals.
• Institutions: pipeline of auditable transactions and markets with execution guarantees similar to legacy financial circuits.
• Developers: ability to create applications that were previously technically unfeasible – for example, custom orders, advanced matching logic, professional DeFi services.

According to Lucas Bruder (CEO of Jito Labs), “BAM opens up a completely new design space” and not only allows contributors to obtain a larger slice, but prepares Solana to be the go-to platform for decentralized capital markets.

What changes with BAM in the revenue and governance model?

The introduction of programmable revenues through Plugins represents an absolute novelty: every actor along the chain, from the programmer to the validator, can directly monetize their contribution. The integrated revenue model is designed to be open, expandable, and progressively permissionless.

The rollout on the mainnet, scheduled within a few weeks (announcement on July 21, 2025), will involve leading validators from the start such as Figment, Helius, SOL Strategies, and Triton One. Looking ahead, the node software will become fully open source and the governance process will be entrusted to the community, effectively opening the door to a complete decentralization of blockspace coordination for Solana.

How to participate and where to learn more about BAM?

The adoption path of BAM will not be closed to a few: developers, validators, and operators can already consult the official introduction page to understand how to integrate into the new pipeline. APIs and documentation are provided to create custom Plugins, access scheduler nodes, and participate in the revenue sharing model.

Once the initial rollout is completed, BAM can be quickly integrated into existing stacks: maximum compatibility with clients and main protocols on Solana will be the driver for the speed of the transition.

What future prospects after the launch of BAM on Solana?

The launch of BAM will mark a turning point for the entire Solana ecosystem. The standards enabled by this architecture (guaranteed privacy, public verification, widespread monetization, zero permission) are designed not only to set new records of efficiency but to attract liquidity, sophisticated users, and next-generation DeFi projects.

The future depends on the ability of the community to seize these opportunities and develop new use cases, leveraging the deterministic programming and radical transparency offered by BAM.
