CIP-0130: Nomura Super Validator Weight 10

1. Summary

This CIP proposes granting Nomura Group / BOOSTRY participation as a Super Validator (SV) on the Canton Network, with a maximum earnable Weight of 10.

The proposed participation is expected to strengthen connections between Japanese and global capital markets, expand institutional access to tokenized financial assets, and accelerate adoption of Canton.

SV Weight will be earned through a milestone-based program with confidential commitments reviewed by the applicable Canton governance bodies.

• Total Earnable Weight: 10 (maximum)

• Accrual Destination: Escrow, consistent with existing SV escrow mechanics

• Confidentiality: The applicable governance bodies will review the milestones and inform the Super Validators when they have been met

2. Motivation

Nomura Group is one of Japan's leading financial services institutions, providing securities trading, investment banking, asset management, and institutional financial services globally.

Together with BOOSTRY and Nomura Research Institute (NRI), Nomura Group is positioned to connect Japan's established securities infrastructure with Canton's global institutional network.

These initiatives are expected to increase institutional adoption, facilitate meaningful production activity, and strengthen Canton's connectivity with Japanese and international capital markets.

3. Deliverables & Milestones

The specific deliverables, milestones, deadlines, verification requirements, and associated Weight allocations for Nomura have been agreed privately with the Tokenomics Committee and SVAC.

The milestone program includes initiatives intended to advance regulated customer access, institutional settlement, collateral integration, production network activity, and broader adoption of Canton within regulated financial markets.

• Milestone Review Process: The applicable governance bodies will confirm whether Nomura has successfully met each milestone.

• Reward Mechanism: Upon confirmation and completion of the applicable governance process, rewards associated with achieved milestones will be released from escrow and the corresponding SV Weight may be assigned on a go-forward basis.

• Confidentiality: Nomura's specific commitments, milestones, timelines, regulatory materials, supervisory materials, and commercial details will remain confidential until the Canton Foundation and Nomura determine that disclosure is appropriate.

4. SV Mechanics

• An extraBeneficiary PartyID associated with the escrowed Super Validator will be established by the Canton Foundation, or by another SV node operator approved to provide SV rewards escrow services, with SV Weight equal to the maximum earnable Weight.

• The Applicant is responsible for coordinating with the Canton Foundation and the operator of the SV node to establish the escrow arrangement.

• The Applicant is responsible for all costs associated with operating the representative SV.

• The representative SV will not mint rewards on a block-by-block basis.

• All representative SV rewards will accrue to the Unclaimed Rewards pool.

• Two-thirds of the Super Validator Operators will update their configurations to allow the escrowing SV node to host the full Weight available under this CIP.

• The Applicant is required to present proof of successfully completed milestones to the Tokenomics Working Group.

• The Applicant must also present a calculation of the amount of Canton Coin it should receive for satisfying each milestone.

• If the Tokenomics Working Group agrees that a milestone has been met and approves the calculation:

• An announcement will be sent through the Tokenomics-Announce mailing list.

• Two-thirds of the Super Validator Operators will assign the approved portion of the Unclaimed Rewards to be minted by the Applicant's Validator.

• Two-thirds of the Super Validator Operators will update their configurations to allow the Applicant to assume the corresponding portion of SV Weight on a go-forward basis.

• If a milestone and its associated rewards are not achieved by the applicable deadline:

• The Canton Foundation will notify the Applicant that the deliverable has not been met.

• The remaining SV Weight associated with the unmet milestone will be removed from the applicable SV operator configurations.

• The Tokenomics Working Group will make a recommendation to the Super Validators regarding the disposition of the related Unclaimed Rewards.

• The Applicant is subject to CIP-0045, Super Validator Operating Requirements.

• If the Applicant has been awarded SV Weight greater than 2.5, it must operate its own Super Validator within six months after crossing that threshold.

• The Applicant's SV will join the network with Weight 0 and may assume additional Weight as the milestones under this CIP are completed and approved.
