Manage dApp Secrets: Create Private Data Sharing
summary
A running secret-management network implements Umbral threshold proxy re‑encryption so data producers encrypt once and policies on Ethereum grant dynamic access later; example: a heart‑monitor uploads ciphertext to IPFS, a policy is created on chain, then three Ursulas perform re‑encryption and with a threshold of two the doctor decrypts locally. Live since Oct 15, with a Warlock stake event drawing 2000+ participants and ~350k stake. Tools: Umbral threshold proxy re‑encryption, IPFS storage and Ethereum policy transactions, CLI + Python + JSON‑RPC APIs.
