Hyperledger Besu vs Canton · JPM Main-Theater Migration Path

Wiki route

This entry sits under systems index. Read it against Hyperledger Besu · EVM-compatible enterprise chain (evolved form of Quorum) for peer / contrast context and fintech index for the broader system / regulatory boundary.

Key facts

• JPM began moving Kinexys’s main theater to Canton in 2026 年 · completion planned for 2027 H1 ^•
• 4 factors drive the migration: DAML is suited to financial contracts · multi-party atomic · founding-member strategy · application-level isolation ^•
• Kinexys Chain will be retained after the migration as an internal testing + EVM-compatible backup ^•
• When other G-SIBs (Citi / HSBC / BNP) build new private chains, Besu remains the default ^•

Mechanism / How it works

Quorum/Besu’s advantage is EVM compatibility: the Solidity toolchain can be reused, and bank customers have high acceptance because they are already familiar with Ethereum concepts. Its weaknesses are that multi-party atomic settlement requires complex combinations of contracts, and Constellation’s off-chain payload isolation is less clean from a regulatory perspective than application-level data isolation. Canton natively provides DAML (functional + obligation-based language) + multi-party atomic settlement + privacy by design, allowing institutional customers (investment banks + asset managers + custody) to collaborate on the same ledger without exposing full state to each other. In the 24/7 repo market + collateral mobility that JPM is trying to build on Kinexys, Canton’s primitives fit materially better than Quorum.

Origin & evolution

In 2015-2020 年, JPM incubated JPMD / Onyx Coin on Quorum and validated the feasibility of stablecoin + internal chain. In 2021 年, Daml/Canton launched an institutional consortium, with DTCC + Goldman Sachs + Morgan Stanley participating. In 2024-11 , JPM renamed Onyx to Kinexys and began evaluating Canton at the same time. In 2026 Q2-Q3 , Kinexys completed partial functional switching to Canton (repo + collateral prioritized). The plan is to complete the full main-theater migration by 2027 H1 , with the Quorum fork converted into an internal testing environment. Citi CTS / HSBC TDS / BNP Securities Services follow similar paths but start from different points: Citi directly runs Canton + Hedera in parallel, while HSBC still centers Besu and has not announced a Canton plan (contrast with public-chain RWA cases such as BlackRock BUIDL expanding back toward institutional chains).
