High-level diagram of block engine
The Jito Block Engine is responsible for:
Ingesting transactions from a relayer
Forwarding those transactions with searchers
Ingesting bundles and transactions from searchers
performing bundle simulation
selecting the best and most profitable transactions for the network
forwarding the best transactions and bundles to the validator for processing.
Since the Jito pipeline is very latency sensitive, it is important to choose a block engine that is located close to you. For Jito bundles to be added to blocks during leader slots, the Block Engine must be able to forward them within the appropriate slot. Optimal round-trip latency between the Block Engine and a validator is <50ms.
If you aren't in a location with low latency access, you can still run Jito-Solana. We are seeing validators with <100ms latency (round trip) operate well given current network and bundle throughput. Note, this latency only impacts Jito bundle inclusion. Votes and non-leader slots are unaffected. Even during leader slots, blocks will still be produced as normal given the relayer's architecture.
We are rapidly expanding our geographic footprint to ensure convenient access for the vast majority of validators. If you don't have a good access point, please communicate your preferences to Brian in Jito's Discord. This enables the team to prioritize new location additions.
Please choose a block engine location nearest to you.
