For a high level discussion of the architecture and benefits of Jito-Solana, checkout our introduction post or this presentation.

Bundles

• Bundles are a list of transactions that are executed sequentially.

• Bundles are executed all-or-nothing. If one fails, the entire bundle is rolled back.

• Bundles can contain tips, which allows users to tip validators for priority treatment.

• Bundles are not forwarded between validators.

Relayer

• Validators can connect to a relayer, which performs filtering and signature verification.

• Validators disconnect their TPU when connected so all packets must come through a relayer.

• Validators fallback if the relayer stops heartbeating or becomes unhealthy.

Block Engine

• Block Engines send high-profit bundles and transactions to validators.

Low Latency Shred Sending

• Shreds can be sent over UDP to an address of one's choice to bypass turbine latency.

Open Source

• Jito-Solana is open source. The client is permissionless to run with no contracts or other requirements.

• The only fee is 5% on MEV tips through Jito's Block Engine. This has no impact staking rewards and only impacts incremental revenue from MEV.
