Morgan Stanley is moving toward a multi-chain architecture that pairs public networks with permissioned rails for regulated use-cases. The blockchain engineer role is required to “integrate at least four blockchains,” including Ethereum, Polygon, Hyperledger, and Canton.

🌐 Public-chain layer: Ethereum for ecosystem/liquidity and Polygon for “lower fees and faster transactions” while staying compatible.

🏦 Permissioned layer: Hyperledger for “channel-level privacy” and customizable consensus for internal/consortium workflows.

🔐 Regulated sync: Canton framed as “privacy-preserving synchronization” suited for regulated markets.

This implies a broader institutional shift toward programmable finance and tokenized-asset infrastructure.
