# BAM (Block Assembly Marketplace)

> The Future of Solana Block-Building

BAM (Block Assembly Marketplace) is a transaction scheduling system for Solana that separates ordering from validation using secure hardware environments.

BAM (Block Assembly Marketplace) aims to transform Solana's transaction processing by introducing specialized BAM Nodes running in Trusted Execution Environments that privately sequence transactions before sending them to validators. The system enables programmable transaction logic through plugins, provides cryptographic attestations for verifiable fairness, and creates new revenue streams for developers and node operators while maintaining Solana's performance characteristics.

## Products

- [Plugin](https://thegrid.id/profiles/bam_block_assembly_marketplace_): BAM will support a plugin architecture that allows developers to customize transaction scheduling logic. Plugin capabilities and APIs are being designed to enable transaction ordering while maintaining the security guarantees of the TEE environment. (Main Product)
- [Validators](https://thegrid.id/profiles/bam_block_assembly_marketplace_): BAM (Blockspace Assembly Market) extends the Jito-Solana client to interface with external schedulers via gRPC, receiving pre-sequenced transaction bundles and executing them in FIFO order with respect to account locks. This design maintains network security while enabling sophisticated transaction ordering strategies. Access to BAM is fully permissionless, and any validator can join mainnet or testnet by following the instructions below.

 (Node Software, Live)
- [Node Operators](https://thegrid.id/profiles/bam_block_assembly_marketplace_): Node operators will run specialized TEE (Trusted Execution Environment) hardware that maintains transaction privacy while enabling verifiable computation. This infrastructure will be crucial for BAM's decentralized and secure operation. (Node Hardware, In Development)
