Proposal: Korean TTA Blockchain Reliability Verification of the Canton Private Synchronizer
Development Fund Proposal Submission
Proposal file: /proposals/canton-tta-brv.md

Impact
Korean institutions are making their first DLT choices now, across three fronts at once: securities firms ahead of the January 2027 STO deadline, and banks and the Bank of Korea as KRW stablecoin and CBDC rails take shape behind it. Those choices lock in the underlying infrastructure for decades, and selection is defaulting toward Hyperledger Besu and Fabric.
This credential is what puts Canton in front of them before that default hardens. The Canton Foundation can verify (under NDA) that a Korean financial authority has confirmed the importance of this credential.

Summary
This proposal funds taking the Canton private synchronizer through Korea's TTA Blockchain Reliability Verification (BRV) ahead of Korea's incoming permissioned-DLT regime, making Canton the first non-Korean DLT (and first privacy-preserving sub-net architecture) to hold the credential Korean financial-infrastructure operators use to evaluate a permissioned chain. Because the result attaches to the software itself, it serves Korea's regulated-DLT rails as one: STO under the Electronic Securities Act, plus KRW stablecoin and Bank of Korea CBDC settlement under the Digital Asset Basic Act. Every participant inherits the credential, and we open-source a TTA-verified reference deployment under Apache 2.0 for reuse across APAC. Total request: 2,750,000 CC (~$330,000 USD at $0.12/CC) across two milestones.

Notes for Reviewers
Eligible funding category: Security reviews, audits, and hardening (the BRV evaluation tests consensus fault tolerance, key management, and ledger integrity of the Canton private synchronizer against the NCSC guideline), plus reference implementations other builders can reuse: the Apache 2.0 TTA-verified reference deployment (verified stack and configuration, reproducible metrics, and test/benchmark harnesses), a portable blueprint for analogous APAC verification regimes.
SIG alignment:
- Primary: Regulatory Compliance
- Secondary: Canton Protocol & Multi-Synchronizer (validates the private synchronizer's BFT consensus, deterministic finality, and privacy sub-net; aligns with the multi-synchronizer roadmap)
- Optional third: Node Deployment & Operations (verification environment, deployment/key-management posture)
Champion: Teagan Buckley, Canton Foundation.
Public-good framing: The grant funds a credential that attaches to the Canton private synchronizer software (not to Nodeinfra or any single operator) and a fully open-sourced (Apache 2.0) TTA-verified reference deployment reusable across APAC. Because it attaches to the software, the credential is inherited equally across STO, KRW stablecoin, and Bank of Korea CBDC and deposit-token domains under the same NCSC guideline, widening the benefit while scope and payment gates stay fixed to BRV of the synchronizer. Nodeinfra's commercial work (the STO issuance platform, securities-firm BD, and the law-firm legal-education engagement) is explicitly fenced into the proposal's Out of Scope section and funded separately; it appears in the Growth and Adoption section only as evidence the credential drives real adoption.
Acceptance criteria are objectively verifiable: Both milestone gates are independently checkable without grantee attestation: TTA confirmation that it is ready to begin BRV, verifiable by the Committee under NDA (M1), and a publicly verifiable TTA-issued BRV result plus the published Apache 2.0 verified reference deployment (M2). The BRV result is binary, so Milestone 2 payment is conditioned on the credential itself rather than on downstream adoption.
Adoption accountability: Adoption indicators are tracked as informational (not payment gates, since they lag issuance and sit with third parties), with a committed public adoption-tracking report in the repo at 6 and 12 months post-issuance.
Timing: The Korean STO law's January 2027 effective date is hard, and infrastructure-operator selection runs 6–12 months ahead of it. The Digital Asset Basic Act follows behind, bringing KRW stablecoin and Bank of Korea CBDC rails onto the same operators in the same window. The 5-month delivery window is matched to placing Canton in the selection pool before those decisions are locked.
