Enterprise Blockchain in TypeScript: Real-World Case Studies, Protocol Mappings, MPC, HSM & Post-Quantum Patterns That Actually Run

Most enterprise blockchain projects die in PoC hell. You've seen it: a flashy demo, some Hyperledger slides, a proof-of-concept that "works on my machine," and then... silence. The pilot never graduates to production. The consortium loses interest. The budget evaporates. The problem isn't the technology—it's that most repositories show you what blockchain can do without showing you how to actually build it. Where's the code for recall traceability that maps to real chaincode? Where's the privacy pattern that actually projects into Besu privacy groups? Where's the MPC implementation you can run locally without spinning up three cloud VMs? This repository is different. enterprise-blockchain by @psavelis delivers 20 runnable examples covering four production-grade business scenarios, three protocol adapters (Fabric, Besu, Corda), MPC secret sharing, HSM key management, and NIST-standardized post-quantum cryptography. Everything runs locally. Everything passes CI. Everything is actually us
