Overview

Jito Tip Router NCN is handling operation of distribution of MEV tips generated from the Jito Tip Distribution protocol. The system is made of 3 components:

• Onchain NCN program
• Node Operator Client
• Permissionless Cranker

Onchain NCN Program (Jito Tip Router Program):

Onchain NCN program has several components:

• Pricing

  • Switchboard determines the relative weight of assets ( jitoSOL, JTO, ... ) deposited in all the Vaults linked to this Jito Tip Router NCN.

• Snapshot

  • Take snapshots of Operator and Vault per epoch.

• Core Logic (Consensus)

  • Prepare Ballot Box, all votes would be collected here.
  • Each operator calculate the merkle tree to produce merkle root then cast vote with produced merkle root.
  • After consensus reached with more than 2/3, cranker can upload the merkle tree of each validator.

• Reward Payment

Node Operator Client

• Node operators will compute a meta merkle root — a merkle root derived from a new merkle tree containing all validator merkle trees.
• Upload meta merkle root on-chain.

Permissionless Cranker

• Take snapshots of Operator and Vault per epoch.
