BGIN Block 14

The Ministry of Economy, Trade and Industry (METI) presents a blockchain technology competition focused on post-quantum cryptography migration and advanced key management. Modelled on established cryptographic standardisation competitions, this initiative invites researchers and developers to propose and benchmark solutions for the next generation of blockchain security infrastructure.

Development of Security Target (ST) and Protection Profile (PP) standards for blockchain systems, aligned with Common Criteria and industry standards. This session adapts established evaluation methodologies to address the unique security requirements of decentralised architectures — including wallet security targets, smart contract security profiles, and cryptographic key lifecycle management.

Preparing blockchain systems for the post-quantum cryptography (PQC) transition. This session examines crypto agility architectures that enable seamless algorithm migration without service disruption, covering NIST PQC standards status, design patterns for agility, and hybrid approaches during the transition period. Participants will review migration strategies for key management, digital signatures, and identity credentials.

Examining security considerations across the blockchain software supply chain, from development tools to deployment infrastructure. This session works toward governance frameworks for supply chain integrity, addressing code signing, dependency management, auditing, and standardised vendor guidelines within the BGIN framework.

A competition showcasing privacy-enhanced authentication and key management solutions. Contributors demonstrate innovative implementations that preserve user privacy while meeting security requirements — from zero-knowledge proof-based authentication to advanced key management architectures. Tied to the METI blockchain technology competition, this session invites the community to evaluate, benchmark, and discuss approaches to privacy-enhanced credentials and key lifecycle management.

Keynote address by the Financial Services Agency (FSA) of Japan.

Best practices and technical approaches for offline key management in high-security environments. Critical for institutional custody, cold storage, and key ceremony implementations. This session examines hardware security modules, air-gapped signing environments, multi-party computation for offline keys, and recovery procedures — including the connection to the Agent Hack's Swordsman key backup and recovery architecture.

As AI agents become increasingly capable of impersonating human behaviour, proving that a participant is a unique real person — without sacrificing privacy — becomes essential for governance, voting, and trust systems. This session advances the Proof of Personhood working group item through case study presentations from World ID, the First Person Project, and Human.Tech, alongside a new theoretical contribution: the three-graph, one-trajectory model for personhood verification. Participants will evaluate the trade-offs between scalability, privacy, and Sybil resistance across biometric, social graph, and credential-based mechanisms.

Day 2 of the BGIN AI Agent Hack. Focus shifts to integration, testing, and demonstrating working components. Teams work toward MVP criteria — sovereign identity via key ceremony, functional agreements, operational Working Group Mages, and enforced privacy budgets — while exploring stretch goals including collaborative document editing, trust network visualisation, and Bonfires integration.

Exploring the intersection of blockchain systems with securities law requirements, focusing on audit frameworks, assurance standards, and risk management practices for compliant operations. Discussion will address on-chain versus off-chain audit trails, regulatory reporting considerations, and international coordination challenges for practitioners navigating emerging digital asset classification frameworks.

This session will first identify the practical challenges involved in using stablecoins in real-world settings as adoption begins to expand, and will consider potential solutions. This session will also ensure time for finalisation of FASE WG's current paper on stablecoin regulation, including a live edit of the current document to reduce the scope by minimising US policy uncertainty in the drafting process.
