The Block Engine found tips before JTO found voters
Jito-Solana validators connect to an off-chain Block Engine where searchers and applications submit signed transactions or atomic bundles. The engine simulates combinations, runs a tip auction and forwards selected bundles to the leader. That service explains where part of Jito’s MEV flow begins, but a JTO balance is not an API key and does not own a searcher’s bundle.
JitoSOL follows a second ledger. SOL deposited in the stake pool mints the JitoSOL receipt at J1toso1uCk3RLmjorhTtrVwY9HJ7X8V9yYac6Y7kGCPn. Staking and MEV rewards raise pool lamports relative to receipt supply; direct unstaking burns JitoSOL for the pool’s withdrawal route. JTO at jtojtomepa8beP8AuQc6eXt5FriJwfFMwQx2v2f9mCL carries none of that direct SOL claim.
The product/token split is therefore structural. Block Engine users buy execution with tips, JitoSOL holders own a pool receipt, and JTO holders can organize decisions. A single brand does not merge those contracts.
