Blockchain Essentials & Blockchain-as-a-Service on CloudFoundry

on YouTube ↗39m

" summary

IBM shows a Blockchain-as-a-Service running on Bluemix/Cloud Foundry: Node.js apps on Cloud Foundry talk to a Hyperledger Fabric ledger running in Docker Swarm with two validating peers, and blocks for Marbles and Commercial Paper appear immutably on every node. Chain logic runs as chaincode in Go, Fabric uses PBFT while Sawtooth offers PoET; choice of consensus changes throughput and trust model. The demos execute trades and record them successfully across peers.
