Blockchain applications in the banking industry
summary
Three concrete PoCs: a commodities traceability pilot with Louis Dreyfus & Co and ING, an Ethereum-based mini-bons ICO for French banks, and a post-trade FX experiment that tries atomic settlement. Implementation uses private Ethereum networks on Azure VMs, smart contracts in Solidity, MetaMask for wallets and gas payments, Merkle trees and hashing for integrity, and encrypted payloads on-chain to keep secrets private. Contracts deploy cost far more gas than update transactions; the FX flow is prototyped but confidentiality and cross-contract coordination remain unresolved.
