How Does Canton Network Keep Transactions Private? On Ethereum and most public chains, every node sees every transaction. Canton (Canton Network) works differently as each party only sees the parts of a transaction it is involved in. (1) Need-To-Know Privacy Unrelated parties don't just miss the details. They don't... even know the transaction exists. (2) Visibility Is Written Into The Contract Canton's smart contract language, Daml, defines who can see each contract. Signatories and observers see it. Everyone else sees nothing unless they're explicitly added. (3) Sub-Transaction Privacy One transaction can be split into separate "views." If Alice pays Bob and Bob pays Charlie in one atomic trade, Alice never learns about Charlie, and Charlie never learns about Alice. A regulator can see a trade too, but only if it's added as an observer. (4) The Infrastructure Is Blind Each view is encrypted for its recipients. The synchronizer, which orders transactions, only sees encrypted messages plus routing data like timestamps and party IDs. It can't read amounts, prices, or terms. (5) Only Stakeholders Validate Instead of every validator checking every transaction, only the parties involved confirm it. This keeps data private without weakening integrity. (6) Privacy Across Apps Transactions can span multiple applications atomically, with the same privacy rules applied throughout. For banks and asset managers, this design addresses a long-standing problem with blockchains: settling on shared infrastructure has usually meant exposing trades, loan terms, and positions to competitors.show more
