“The chain is only as strong as its weakest link, but first you must map every forge.” - privacymage
A protection profile development session navigates the core security infrastructure problem: you can’t protect what you haven’t inventoried. Their focus shifted from hardware to software - specifically parsers and Ethereum clients - because that’s where vulnerabilities actually concentrate.
Key insight: traditional finance custody due diligence is a threat intelligence sharing problem in disguise. Banks acquiring custody providers (Standard Chartered/Zodiac) need standardized evaluation frameworks, but without shared threat intelligence about parser exploits and client vulnerabilities, every security assessment happens in isolation.
The ISO document purchasing bottleneck reveals a meta-problem: developing security standards requires buying existing standards, creating paywalls that prevent the broad adoption security depends on. 
This is why our Taxonomy of Harms work matters - protection profiles need harm enumeration before writing security requirements. The STIX/TAXII integration becomes essential here: custody providers and banks need ecosystem-wide threat intelligence, not siloed evaluations.

[Proverb Divined] “The chain is only as strong as its weakest link, but first you must map every forge.”
The WG convened to advance protection profile development for smart contracts within blockchain ecosystems, specifically targeting Ethereum. Core challenge: securing the software supply chain across parsers, clients, and custody infrastructure while meeting traditional finance regulatory expectations. This represents the fundamental infrastructure security problem - you can’t protect what you haven’t inventoried.
Strategic decisions: Purchase necessary ISO documents to accelerate profile development, engage Ethereum EIP authors for technical insight, and explore traditional finance institutions’ third-party custody requirements to ground standards in real-world use cases.
1. Stakeholder Mapping & Engagement Strategy:
Prioritize Ethereum EIP authors over hardware vendors
Focus on software developers building parsers and clients
Engage traditional finance institutions exploring custody solutions
Cast: This stakeholder prioritization mirrors your approach in the Taxonomy of Harms work - identify where the actual vulnerabilities concentrate rather than where we assume they should be. EIP authors are the ontological authorities for smart contract security just as forensics practitioners were for your blockchain analytics distinction. The supply chain threat surface isn’t in the hardware but in the software interpretation layers.
2. Software Supply Chain Vulnerabilities:
Parser security as critical threat vector
Ethereum client implementations as attack surfaces
Third-party custody provider evaluation needs
Cast: This is exactly why your STIX/TAXII threat intelligence sharing framework matters. Traditional finance institutions need standardized methods to evaluate custody providers, but without shared threat intelligence about parser vulnerabilities and client exploits, each institution reinvents due diligence in isolation. The protection profile becomes infrastructure for trust network formation - banks need to know not just “is this provider secure” but “what specific threats has this provider mitigated.”
3. ISO Standards Access & Documentation:
Challenge accessing ISO documents through official channels
Decision to purchase documents to accelerate development
Need for specific vulnerability handling and information sharing standards
Cast: The ISO document purchasing bottleneck highlights a meta-governance problem you’re addressing at BGIN - standardization work requires access to existing standards, but paywalls fragment knowledge. Your neutral convening power approach tries to solve this by making BGIN outputs freely accessible. The irony: they need to buy standards to write standards that enable security, when security depends on broad adoption that paywalls prevent.
4. Traditional Finance Integration:
Banks acquiring custody providers (e.g., Standard Chartered/Zodiac Custody)
Regulatory due diligence requirements for third-party services
Need for standardized evaluation frameworks
Cast: This validates the IKP-FASE joint initiative approach. Traditional finance can’t evaluate blockchain custody without understanding the harm taxonomy - what threats exist, how they manifest, what mitigations work. The consortium acquisition model (banks buying custody providers) creates vertical integration but doesn’t solve the horizontal coordination problem. That’s where your multi-stakeholder frameworks become essential infrastructure.
This meeting exemplifies three critical dynamics in blockchain security standardization:
The Inventory Problem: Protection profiles require comprehensive threat surface mapping. You can’t write security requirements for components you haven’t identified. The parser/client focus emerged from recognizing where actual vulnerabilities concentrate.
The Standards Access Paradox: Developing security standards requires purchasing existing standards, creating financial barriers to the very knowledge that enables secure systems. This perpetuates fragmentation.
The Due Diligence Dilemma: Traditional finance needs objective evaluation criteria for custody providers, but without standardized frameworks and shared threat intelligence, every institution develops bespoke assessment processes that don’t interoperate.
This session demonstrates why the Taxonomy of Harms in Blockchain, Finance and Identity is critical infrastructure:
Protection profiles require harm enumeration before writing security requirements
Traditional finance due diligence needs standardized threat categories to evaluate custody providers
Parser/client vulnerabilities need classification within broader supply chain threat models
Your BGIN Agent Hack MVP’s multi-agent system becomes directly applicable here: Archive agent maintains vulnerability disclosure history across EIPs and client implementations, Codex agent tracks ISO standards evolution for protection profiles, Discourse agent facilitates dialogue between smart contract developers and traditional finance security teams.
The STIX/TAXII integration is essential - custody providers and banks need shared threat intelligence about parser exploits, client vulnerabilities, and supply chain attacks. Without this, every security evaluation happens in isolation.
Specific Connection to EIP 8004 (Agentic Trust): The mention of EIP 8004 relates directly to your “agent duality” challenge. As AI agents increasingly interact with smart contracts, the trust model shifts from “verify human intent” to “verify agent authorization.” Protection profiles must address this emerging threat surface.
