Jito proposes a new block-building mechanism for Solana
The post Jito proposes a new block-building mechanism for Solana appeared on BitcoinEthereumNews.com. Jito, one of the key Solana validators, has proposed a new block building system. The goal is to create private pools with optimized block building and no concerns about sandwich attacks. Jito is working on a new block building system, tailored to the needs of apps and DeFi protocols. The main goal is to prevent sandwich attacks, by creating a safe block-building venue. Called Block Assembly Marketplace (BAM), Jito said the system would enable secure block building. Introducing BAM: The Block Assembly Marketplace that revolutionizes how Solana processes transactions. Private. Transparent. Verifiable. This is how Solana wins ⬇️ pic.twitter.com/KP8RwloHM7 — Jito (@jito_sol) July 21, 2025 Sandwich attacks or front-running transactions are a problem for Solana, affecting DEX activity. A year ago, sandwich attacks were one of the biggest threats for the network. Solana has no mempool, though previously Jito offered access to transaction data. One of the problems is that even private pools may not be secure and inject front-running transactions. Jito changes Solana block-building Solana has a complex legacy system of block building, with no dedicated MEV builders. Jito is one of the main block optimizers, working through auctions for favorable transaction placements. There are also services that sponsor the SOL gas fee and offer traders a safe endpoint to avoid sandwich attacks. Traders and users also unleash MEV bots, which compete for front-running transactions. Jito will upgrade its auction system and replace it with the Block Assembly Marketplace (BAM). The new approach to transaction processing will include a new layer of hardware nodes, additional validators, and plugins to connect developers. BAM is built for the needs of developers aiming to launch apps with specific transaction-ordering rules. One of the key features will be specialized encryption hardware, which will keep transactions encrypted until execution, and will verify all…
