Decentralized Access Control with Medusa

Talkat FVM Space Warp 2023 · 2023-01-20..02-10· [web3, security]
slides:none on file

Medusa runs a threshold re-encryption network that lets a smart contract register a 32‑byte encrypted key (not the whole file) on-chain, then re-encrypt that key for a buyer after on‑chain payment. Demo uses Filecoin/IPFS for storage, Arbitrum and Hyperspace testnets for contracts, and a simple OnlyFiles dApp; demo completes payment→event→gossip→on‑chain response cycle with minor live glitches. SDK exposes register ciphertext, request re‑encrypt, and an OracleResult callback for front ends.
