A working PoC, what changes in the programming model, and what I learned getting public review from an FSC core maintainer along the way. If you maintain a Hyperledger Fabric chaincode in production today, there's a question quietly hovering over your roadmap: what happens to my application on Fabric-X? Fabric-X — Hyperledger's next-generation re-architecture — keeps the governance model, the X.509 PKI, and the execute-order-validate transaction lifecycle. But it removes three things you've probably built habits around: the monolithic peer, the SmartBFT/Raft orderer, and chaincode itself. Business logic that used to live inside a Go chaincode binary now lives inside views running on Fabric-Smart-Client (FSC) nodes. So: what does your chaincode look like in this new world? I built a working proof-of-concept that answers that question for the canonical asset-transfer-basic Go chaincode — the one every Fabric tutorial starts with. All eight chaincode methods are ported to FSC views.…
