Overview

What Occlusion is

Occlusion is a routing layer for Robinhood Chain (chain id 4663) in which a swap is submitted as a shielded intent rather than a readable transaction. The intent is committed into an Orchard-derived note; solvers compute routes against that commitment, and the chain observes only the settled result in the block where execution occurs. A Bittensor subnet audits the public trace after settlement and writes integrity scores for every solver to an on-chain registry.

The problem it solves

On a transparent chain, route discovery is itself a signal. Solvers and searchers probe candidate paths with cheap, revertible transactions, and any party watching the mempool can reconstruct the intended trade before it lands, then front-run or sandwich it. Private mempools shift trust to an operator who still reads the order. Occlusion removes the readable order entirely: there is nothing in the mempool to probe, copy or reorder, and residual leakage from the executed trace is measured rather than assumed away.
