Nomura / BOOSTRY Super Validator proposal, November 5. Source.
A new Canton governance proposal would give Nomura Group and BOOSTRY a path to Super Validator participation, with rewards earned by delivering agreed milestones.
The November 5 draft proposes a maximum reward weight of 10. It aims to connect Japanese and international financial markets through Canton, but the detailed commercial commitments remain confidential. Approval is still required.
At a glance
- Applicants: Nomura Group / BOOSTRY.
- Maximum earnable weight: 10.
- Reward release: subject to completed milestones and governance confirmation.
- Current stage: a published proposal; SBI has offered to sponsor it.
What does a Super Validator do?
Super Validators help operate Canton’s Global Synchronizer, the shared service that coordinates transactions across participating applications. The proposal combines that network role with commitments intended to bring institutional activity to Canton.
Reward weight is not a cash grant. It is a parameter used in allocating Super Validator rewards. A maximum weight of 10 does not mean 10 CC, a fixed dollar payment or a guaranteed investment return.
How Nomura would earn the rewards
The draft uses an escrow arrangement: potential rewards would be held back while the applicant works towards its commitments. Releasing them would require evidence and the specified governance steps.
- Agree the framework. Governance would first need to approve the proposal and establish the reward arrangement.
- Deliver a milestone. The applicant would submit evidence and a calculation of the CC associated with that milestone.
- Review the evidence. The Tokenomics Working Group would assess whether the requirement had been met and the calculation was appropriate.
- Implement the decision. The draft requires action by two-thirds of Super Validator operators to release the approved rewards and assign the corresponding ongoing weight.

What is public, and what is confidential?
The public draft identifies broad aims: regulated customer access, institutional settlement, collateral integration and production activity. Collateral is an asset pledged to support a financial obligation.
Specific deliverables, deadlines and the weight assigned to each milestone are not disclosed. The relevant governance bodies would review those commitments and inform Super Validators when milestones were met.
That gives readers a view of the reward structure, but not enough detail to name an upcoming product or calculate a launch date. If an agreed milestone were missed, the draft provides for removal of the associated unearned weight.
Why Nomura and BOOSTRY are relevant
Nomura is a Japanese financial services group, and BOOSTRY develops infrastructure for securities issued using blockchain technology. A joint announcement from 2023 describes BOOSTRY’s role in the ibet for Fin securities ecosystem.
Nomura also appears in the Japanese government-bond collateral pilot involving Mizuho, JSCC and Digital Asset. That earlier pilot and this proposed Super Validator arrangement are separate developments.
What happens next?
SBI offered to sponsor the proposal in a follow-up message. Sponsorship helps a proposal move through the process; it is not an approval vote.
The public draft still uses a placeholder CIP number. A completed governance decision and subsequent implementation would be needed before describing the proposed participation or rewards as active.
