LSEG named super validator on Canton Network

London Stock Exchange Group has been named a super validator for the Canton Network and will run validator node(s) to validate transactions and take part in the network’s governance and consensus.

Under the appointment LSEG will operate validator nodes alongside other institutional participants that maintain the network’s ledger and consensus. Responsibilities include validating transactions, enforcing network rules and contributing to the operational resilience of the platform used for private, cross-ledger smart contracts.

The Canton Network is a permissioned interoperability layer designed to let organizations exchange assets and data across different ledgers while preserving privacy and legal finality. The network supports DAML smart contracts and is aimed at regulated financial institutions that require private, auditable shared workflows between counterparties without exposing full transaction details on public blockchains.

Super validators are tasked with producing and verifying ledger entries, ensuring transaction finality and participating in governance procedures. Appointment requires meeting the network’s onboarding, technical and compliance standards. Validators coordinate with members and administrators to maintain permissioned access and privacy controls.

LSEG operates exchanges, post-trade services, market data and analytics. The group has been developing capabilities in distributed ledger technology and tokenisation for capital markets. Through running validator infrastructure, LSEG will operate and test technical and operational requirements for connecting institutional workflows to permissioned distributed ledgers and assessing potential integrations with its exchange and post-trade services.

The Canton protocol was developed by Digital Asset. Permissioned networks such as Canton restrict participation to known entities, enable privacy controls and require governance checks and technical standards before onboarding. Operators of validator nodes are responsible for maintaining network performance, security and governance.
