Jito unveils major upgrade to block-building architecture
The post Jito unveils major upgrade to block-building architecture appeared on BitcoinEthereumNews.com. Jito is bringing a major upgrade to the way blocks get built on Solana, Lightspeed has learned exclusively. Jito — whose validator client accounts for 87% of all Solana stake — will begin routing transactions through a piece of infrastructure it’s calling the block assembly marketplace, or BAM. Jito says BAM will limit toxic MEV, make Solana more suitable for perps exchanges and CLOBs, and let apps share revenue with users. When a user transacts on Solana, chances are that the transaction will go through the Jito block engine, which is essentially an off-chain blockspace auction. The product is a cash cow: Blockworks Research data estimates Jito Labs made roughly $25 million in Q4 of 2024 just from its commission on fees paid via the block engine. When Jito started out, it didn’t quite expect the block engine to get as big as it did, Jito Labs CEO Lucas Bruder told me. Having become a core part of Solana’s supply chain, the project began wondering what its next move should be. After reasoning that Solana’s market structure is too opaque and seeing the success other chains were having in giving apps better control over transactions, Jito settled on building BAM. BAM comprises a network of nodes who order transactions and send them to validators running Jito’s soon-to-be-upgraded client. The nodes will run within Trusted Execution Environments (TEEs), so the transaction flow is kept private until execution. Jito believes this privacy can help mitigate some negative MEV strategies like sandwich attacks. The correct order of transactions is provable through onchain attestations, creating an audit trail. BAM nodes will initially be operated by Jito Labs, but it plans to add more nodes with an end goal of 50-100, Bruder said. Jito also wants to open-source the BAM software later in 2025, Bruder…
