According to a press release shared with CoinDesk, BAM is designed to make “transaction sequencing transparent and verifiable,” while enabling programmable innovation at the blockspace layer, unlocking new revenue opportunities for developers and reducing the harmful effects of Maximal Extractable Value (MEV).
The launch builds on Jito’s already established infrastructure, including its widely adopted validator client, and the Jito Block Engine.
A critical piece of this system is the use of Trusted Execution Environments (TEEs). TEEs function like secure black boxes, simulating and ranking transaction bundles submitted by searchers without revealing sensitive data. This ensures private strategies remain protected, while still allowing validators to verify the outcome, aimed at striking a balance between transparency and confidentiality.
BAM introduces a modular architecture made up of three key components. BAM Nodes are specialized schedulers that privately organize transactions using secure hardware. BAM Validators are the validators running the updated Jito-Solana software client and receive the ordered transactions from these nodes and execute them on-chain. Finally, Plugins will offer developers, traders, and applications a programmable interface to interact with the scheduler, enabling customized transaction logic. These plugins also open up a new revenue model where developers can monetize custom logic, and validators, node operators, and stakers can share in the value they help generate.
According to the team, BAM will be launching on mainnet in the coming weeks with an initial set of validators led by key Solana ecosystem players like Figment, Helius, SOL Strategies and Triton One.
"BAM opens up an entirely new design space for developers to build applications that weren't possible before," said Lucas Bruder, CEO of Jito Labs, in the press release. "It gives builders more control, creates new ways to generate and share value, and lays the groundwork for a more dynamic, composable blockspace economy on Solana."

KuCoin captured a record share of centralised exchange volume in 2025, with more than $1.25tn traded as its volumes grew faster than the wider crypto market.
What to know:
- KuCoin recorded over $1.25 trillion in total trading volume in 2025, equivalent to an average of roughly $114 billion per month, marking its strongest year on record.
- This performance translated into an all-time high share of centralised exchange volume, as KuCoin’s activity expanded faster than aggregate CEX volumes, which slowed during periods of lower market volatility.
- Spot and derivatives volumes were evenly split, each exceeding $500 billion for the year, signalling broad-based usage rather than reliance on a single product line.
- Altcoins accounted for the majority of trading activity, reinforcing KuCoin’s role as a primary liquidity venue beyond BTC and ETH at a time when majors saw more muted turnover.
- Even as overall crypto volumes softened mid-year, KuCoin maintained elevated baseline activity, indicating structurally higher user engagement rather than short-lived volume spikes.
