“The lock that protects all doors cannot protect itself.” - privacymage
A session on the existential cryptographic crisis facing blockchain infrastructure. Quantum computing doesn’t just threaten specific applications - it undermines the cryptographic primitives everything is built on. Bitcoin’s immutability is now a vulnerability; Ethereum’s complexity creates new attack surfaces.
The governance challenge: how do you coordinate ecosystem-wide change when the system’s value proposition is resistance to change? Current holders perceive PQC migration as a threat to their assets, creating ideological and financial barriers to necessary security upgrades.
Key insight: “Store now, decrypt later” attacks mean the safe migration window may have already closed. Quantum computers are being developed in secrecy (modern Manhattan Projects), so visible breakthroughs will come after covert capabilities already exist. 
This matters for our work because every identity system, key management protocol, and privacy-preserving credential we build relies on these same vulnerable primitives. Proof of personhood systems binding biological uniqueness to quantum-vulnerable keys aren’t building permanent credentials - they’re creating pre-compromised ones.
The proposed research project (2-3 year timeline) needs to integrate with our Taxonomy of Harms work. You can’t migrate what you haven’t inventoried; you can’t protect against threats you haven’t categorized. BGIN’s neutral convening power becomes critical infrastructure for coordinating across Bitcoin maximalists, Ethereum developers, and quantum-resistant chain advocates.

[Proverb Divined] “The lock that protects all doors cannot protect itself.”
The WG convened to address the existential cryptographic threat posed by quantum computing to blockchain infrastructure. Core challenge: migrating systems built on immutability assumptions when the cryptographic foundations themselves become mutable through quantum attacks. This represents the ultimate governance paradox - how to coordinate ecosystem-wide change when the system’s value proposition is resistance to change.
Strategic decision: Initiate comprehensive research project (2-3 year timeline) to study PQC migration strategies across the entire blockchain ecosystem, including stakeholder incentive alignment, technical feasibility, and governance mechanisms for achieving global consensus.
1. The Immutability Paradox:
Bitcoin’s immutability is now a vulnerability for PQC migration
Ethereum’s programmable complexity creates different attack surfaces
New quantum-resistant chains (QRL) require user adoption from scratch
“Store now, decrypt later” attacks create timeline urgency
Cast: This strikes at the heart of your key management and identity work. Every cryptographic primitive you’re building proof of personhood systems on - signatures, zero-knowledge proofs, credential issuance - faces the same quantum threat. The “irreplaceable biological data” problem you identified in World ID becomes even more critical: if biometric credentials are signed with quantum-vulnerable keys, they’re not actually irreplaceable, they’re pre-compromised. Your decentralized identity architectures need crypto-agility by design, not as retrofit.
2. Ecosystem Coordination Complexity:
Simultaneous updates required: wallets, nodes, oracles, miners, hardware
Ethereum’s PoW→PoS transition took years as precedent
Financial incentives misaligned across stakeholders
Ideological resistance from current asset holders
Cast: This is the multi-stakeholder coordination problem you face at BGIN, but with existential stakes. The neutral convening power you’re building becomes critical infrastructure here - no single entity can mandate PQC migration, but without coordination mechanisms, the ecosystem fragments into quantum-vulnerable islands. Your experience with cross-working group coordination (IKP-FASE-CYBER) directly maps to coordinating wallets-nodes-miners-exchanges for crypto-agility.
3. Incentive Misalignment & Cognitive Dissonance:
Current owners perceive migration as threat to asset value
Ideological attachment to “code is law” immutability
Lack of visible quantum threat timeline creates complacency
Financial incentives needed to overcome resistance
Cast: This is reputation economics and tokenization governance in crisis mode. The same mechanisms you study for positive coordination become barriers to necessary change. Bitcoin holders have “skin in the game” that makes them resist migration even when it’s existentially necessary. Your work on onchain credentials and wallet governance needs to address this: how do you create cryptographic credentials that can survive foundation changes? The First Person Project’s trust network approach becomes essential - trust must reside in social graphs, not just cryptographic primitives.
4. Research Project Scope:
Comprehensive study covering entire ecosystem
Stakeholder incentive analysis
Technical migration pathways
Governance mechanisms for consensus
Quantum computing breakthrough indicators
Cast: This aligns perfectly with your Taxonomy of Harms methodology. You can’t migrate what you haven’t inventoried; you can’t protect against threats you haven’t categorized. The PQC migration research project needs the same structured approach you’re applying to blockchain forensics/analytics distinction and PoH verification frameworks. Each vulnerability class needs enumeration, each stakeholder needs analysis, each migration pathway needs risk modeling.
This meeting exemplifies three critical dynamics in cryptographic infrastructure governance:
The Foundation Replacement Problem: You cannot rebuild the foundation while the building stands upon it. PQC migration requires coordinating changes to primitives that everything else depends on, without breaking dependencies during transition.
The Timeline Uncertainty Paradox: Quantum threats are both imminent (in research labs) and distant (for practical attacks), creating cognitive dissonance that prevents coordinated action. “Store now, decrypt later” attacks mean the window for safe migration may have already closed.
The Ideological-Technical Tension: Blockchain ideology valorizes immutability, but cryptographic reality demands agility. The same properties that make blockchain valuable make it vulnerable to paradigm shifts in computational capability.
This session demonstrates why PQC readiness must be integrated into the Taxonomy of Harms in Blockchain, Finance and Identity:
Identity systems built on quantum-vulnerable signatures face complete compromise
Key management systems need crypto-agility architecture from inception
Proof of personhood systems must not bind biological uniqueness to quantum-vulnerable keys
Privacy-preserving AI systems relying on ZK proofs need post-quantum primitives
Your BGIN Agent Hack MVP’s multi-agent system becomes critical for PQC coordination: Archive agent maintains cryptographic primitive evolution history and vulnerability disclosures, Codex agent tracks PQC standards development across NIST/ISO/IETF, Discourse agent facilitates stakeholder dialogue across the fragmented ecosystem (Bitcoin maximalists, Ethereum developers, enterprise consortia, quantum-resistant chain advocates).
The STIX/TAXII integration is essential - the ecosystem needs shared threat intelligence about quantum computing breakthroughs, cryptographic breaks, and migration attack surfaces. Without this, each project attempts PQC migration in isolation.
Specific Connection to Your Work:
Wallet governance: PQC migration requires wallet standards that can upgrade cryptographic primitives without losing user access
Onchain credentials: Need to architect credential systems that can survive signature algorithm changes
Privacy tech: Your privacy-preserving AI work with Kwaai depends on cryptographic primitives that need quantum resistance
Decentralized identity: Self-sovereign identity means users control keys, but quantum breaks mean those keys become liabilities not assets

I’m planning to circulate the Block13 meeting report to anyone I’d like to invite the call in Feb for this proj. I don’t think these people would understand Mitchell’s RPP related items, so I would propose the simpler version that I added some details to Dr. Matsuo’s AI system’s output:
BGIN REPORT: CRYPTO AGILITY AND PQC MIGRATION
Post-Session Comprehensive Summary
This session focused on the existential challenges and strategic pathways for migrating blockchain technologies, specifically Bitcoin and Ethereum, to post-quantum cryptography (PQC). While some estimates place the arrival of cryptographically relevant quantum computers (CRQCs) within 3 to 4 years, the session emphasized that Crypto Agility must be addressed as a general protocol requirement. The discussion moved beyond theoretical threats to analyze real-world hurdles: the “Burn vs. Steal” dilemma for dormant assets, the lack of standardized evaluation criteria for “Quantum Secure” protocols, and the complexity of updating decentralized infrastructures. Key outcomes included a proposal for a multi-year BGIN research project to analyze stakeholder incentives and the potential for LLM-driven formal verification to secure new PQC standards.
II. Key Discussion Points
Technological and Ideological Challenges
Negotiation vs. Consensus: Unlike point-to-point protocols (e.g., TLS) that use cipher suites to dynamically negotiate algorithms, blockchains cannot easily negotiate among an unbounded number of nodes without risking forks.
Transition Vulnerabilities: Asynchronous updates across nodes during migration periods increase fragility to 51% attacks.
The Immutability Paradox: Bitcoin’s greatest innovation—immutability—is now its “Achilles heel,” as legacy addresses (Pay-to-Public-Key) are vulnerable to quantum discovery.
Incentive Models and User Adoption
Short-termism: Many stakeholders (miners/nodes) prioritize short-term price stability over long-term security. Discussions of migration can be perceived as a threat to asset value, leading to “cognitive dissonance” in the community.
The “Burn vs. Steal” Dilemma:
Burn: Forcing active migration disenfranchises owners of dormant/lost accounts (e.g., Satoshi-era coins).
Steal: Making migration optional allows quantum attackers to steal legacy funds, resulting in a non-consensual wealth redistribution to whoever builds the first CRQC.
Complexity of Ecosystem & Modular DSAs
The ecosystem (wallets, nodes, oracles, miners, hardware) must be updated simultaneously.
Modular DSAs: A proposal was made for a modular architecture where Digital Signature Algorithms (DSAs) are pluggable, allowing governance to swap compromised algorithms for stronger backups without rebuilding the chain.
Historical Precedents & “Benevolent Dictators”
Ethereum’s Merge: The transition from PoW to PoS took several years even under a “benevolent dictator,” illustrating that decentralized migration is inherently slow.
2018 Incident: A 2018 Bitcoin inflation vulnerability was managed by developers privately reaching out to miners—a “direct negotiation” model that contrasts with the ideal of decentralized transparency.
Research and Indicators
The Manhattan Project Parallel: Quantum breakthroughs are likely being developed in state-funded secrecy.
Proxies for Urgency: Quantum attacks on non-blockchain systems could serve as “clouds turning gray” indicators for the industry to hasten migration.
The talk distinguished between specific PQC Migration and general Crypto Agility.
Three Pillars of Difficulty:
Consensus Constraints: Unlike TLS, blockchains cannot dynamically negotiate “cipher suites” without risking massive forks.
The Fragile Window: Asynchronous node updates create a window where the network is vulnerable to 51% attacks.
Economic Resistance: Stakeholders often prioritize short-term price stability over long-term security.
Requirements: Proposed that any PQC transition must ensure signature unforgeability, early adoption incentives, and address preservation to maintain market consistency.
QRL was presented as a 7-year “geriatric” proof-of-concept that has used NIST-standard XMSS since block one.
Zond (QRL 2.0): Introduced the Zond hard fork, which adds EVM compatibility and moves to PoS, providing a “Quantum Insurance Policy” for Ethereum developers to recompile Solidity code in a secure environment.
Manhattan Project Analogy: The presenter argued that “Q-day” will not be publicized; nation-states will keep breakthroughs secret to exploit financial and national security targets.
Presented a pipeline to ensure the mathematical soundness of PQC standards like TSL (Top Single Layer) encoding.
The “Burn vs. Steal” Dilemma: A collaborative debate on the ideological conflict for Bitcoin (BIP 360).
Burn: Protecting the network by forcing active migration, effectively “burning” dormant Satoshi-era coins.
Steal: Maintaining user property rights by leaving funds accessible, effectively allowing quantum-capable entities to “steal” legacy wealth.
The Criteria Gap: Participants emphasized that we are “flying blind.” We lack a methodology to audit an entire blockchain protocol for quantum fragility beyond its signature scheme.
Hash and Parameter Migration: Noted that agility must include hash functions; output sizes may need to double to defend against Grover’s Algorithm, adding further complexity to state-bloat issues.
1. Establish Evaluation Criteria for Quantum Secure Protocols
Develop a methodology to verify if a combined blockchain protocol (not just cryptographic primitives) is quantum-resistant
Address the gap that NIST evaluates primitives, but no standardized criteria exist for protocol-level quantum security assessment
2. Define PQC Migration Requirements
Formalize core requirements: signature unforgeability, dormant account support, early adoption incentives, and address preservation
Include hash function migration requirements (output size considerations for Grover resistance)
Establish clear timelines for disabling legacy DSAs (ECDSA, BLS) post-migration—a topic currently absent from most proposals
3. Initiate BGIN Research Project
Goal: Publish a study/research report within 2-3 years covering the entire blockchain ecosystem
Focus: Analyzing stakeholder incentives and defining “Quantum Secure Protocol” requirements to cover all complex ecosystems
4. Community Outreach
Collaborate with different blockchain communities to gather diverse perspectives on PQC migration.
Organize follow-up sessions or workshops to further discuss and refine the research project.
Circulate anonymized meeting report to all participants immediately
V. Conclusion
The session concluded with a stark realization: the “Chicken Race” against quantum development is underway. Whether through a “Tidal Wave” (sudden Black Swan) or a “Tide” (gradual migration), the industry must move toward modularity and formal verification. The proposal to create a new BGIN research project was met with consensus as the essential next step.
