Canton Network launched in May 2023 as the operational network built on Digital Asset’s DAML (Digital Asset Modeling Language) smart contract platform. Where most blockchain networks publish all transaction data to all participants, Canton’s fundamental architectural innovation is privacy: every participant in the Canton Network sees only the transactions they are directly party to. This sub-transaction privacy model addresses one of the most significant obstacles to institutional blockchain adoption — the requirement that competing financial institutions share sensitive trade data on a common ledger.
The Privacy Problem in Institutional Blockchain
Consider why a public blockchain like Ethereum is problematic for Goldman Sachs trading a bond with Morgan Stanley: every transaction on Ethereum is visible to all observers. Goldman cannot expose its order flow, client positions, or counterparty identities to competitors. Permissioned blockchains like Hyperledger Fabric solve this partially through channels — private communication paths between specific parties — but managing channels across dozens of institutions is operationally complex.
Canton’s DAML-based model solves the privacy problem at the protocol level. Each DAML contract (a smart contract written in the DAML language) specifies exactly which parties are “signatories” and “observers” to that contract. Only those parties receive the contract data. The global Canton network coordinates state — ensuring that the Goldman-Morgan Stanley bond trade cannot result in the bond being double-spent — without revealing the transaction to any other participant. Other participants can verify that the ledger state is consistent without seeing the content of transactions they are not party to.
DAML: The Financial Smart Contract Language
DAML (Digital Asset Modeling Language) is a purpose-built programming language for financial contracts, developed by Digital Asset Holdings (founded by ex-Goldman Sachs CEO Blythe Masters). Key characteristics:
Rights and obligations: DAML models financial contracts as explicit rights and obligations — party A has the right to receive payment from party B on date X, subject to condition Y. This maps directly to how financial contracts are understood legally and operationally.
Composability: DAML contracts can be composed — a bond contract can reference a settlement contract, which references a payment contract — creating programmable multi-step financial workflows.
Portability: DAML can run on multiple backends: the Canton Network (primary), Hyperledger Fabric, Besu, Postgres (for testing). Institutions that write DAML contracts are not locked to Canton.
Auditability: DAML’s type system enforces that all parties’ rights are explicitly defined, making contracts auditable by legal and compliance teams without requiring blockchain expertise.
Participating Institutions
Canton Network participants as of 2026 include: Goldman Sachs, BNP Paribas, Cboe Global Markets, Deloitte, Deutsche Börse, SIX Digital Exchange, Standard Chartered, and 25+ additional financial institutions. The participation structure distinguishes between operator nodes (institutions running Canton infrastructure and validating transactions) and participants (institutions using the network without running infrastructure).
Pilot Results
The Canton Network’s 2023 pilot demonstrated synchronized transactions across institutional sub-ledgers:
- Tokenized bond issuance: A bond was tokenized and sold across multiple institution ledgers with simultaneous settlement in cash tokens.
- Repo transactions: Overnight repo with DvP (Delivery versus Payment) settlement occurred in seconds rather than T+1 or T+2.
- Fund subscriptions: Tokenized fund shares and cash settled simultaneously, eliminating settlement risk.
- Cross-collateralization: Margin calls on derivatives were fulfilled using tokenized bonds from a separate ledger — demonstrating cross-ledger collateral mobility.
Relationship to Public Blockchains
Canton is separate from and not EVM compatible. DAML is a proprietary language. Institutions that invest in Canton/DAML development are building on a technology stack controlled by Digital Asset Holdings, creating vendor dependency. This tradeoff — privacy and financial-services focus vs. open-source ecosystem breadth — is the central Canton adoption question. Institutions that prioritize privacy (Goldman, BNP) find the tradeoff acceptable; institutions that prioritize public blockchain ecosystem access (DeFi integration, Ethereum tooling) find it limiting.
Significance for US Institutional Tokenization
Canton’s significance is strategic: if the largest financial institutions coordinate on a common DLT infrastructure for post-trade operations — settlement, collateral management, repo — tokenized assets that operate on Canton become natively interoperable with the existing institutional financial market infrastructure. DTCC’s Project Ion and Canton are not yet integrated, but both represent the institutional infrastructure layer that tokenized assets will eventually settle through.
