Executive Summary
What the company appears to be
Proof-of-Silence™ is a self-reported cryptographic accountability layer for AI decisions, designed to provide verifiable decision trails with tamper-evident records. It uses Ed25519 signatures and SHA-256 hash chains to record AI-generated answers alongside one of four verdicts: ACT NOW / WAIT / SILENCE / REJECT.
What changed
The project was built during a 3-day hackathon (OpenAI 2026) by a solo founder, Jerzy Skiba, who previously worked in construction. It is described as a prototype with a live demo and includes implementation details such as signature verification logic and integration with GPT-5.6.
The single most important open question
Is there evidence of any real-world usage or pilot integrations beyond the hackathon demo? The description states intentions to pursue pilots but does not confirm traction or adoption.
What The Product Actually Is
The description states that Proof-of-Silence™ is a cryptographic accountability layer for AI decisions. It records AI-generated answers in a tamper-evident ledger using SHA-256 hash chains and Ed25519 signatures. Each decision is evaluated against evidence completeness, confidence, and risk class, resulting in one of four verdicts: ACT NOW / WAIT / SILENCE / REJECT.
The system is described as fail-closed by design, meaning it stops when evidence is insufficient rather than guessing.
Evidence
- The product uses Ed25519 signatures per block and SHA-256 hash chains.
- It integrates with GPT-5.6 as the answering model.
- Verdicts are determined via a rule-based engine (confidence ≥ 80 AND acceptable risk AND verified evidence).
- A demo is available where tampering fails on specific signature verification.
Inference The system appears to be a proof-of-concept or prototype built for demonstration purposes, not yet deployed in production environments.
Positioning & Claim Evolution
The description positions Proof-of-Silence™ as an accountability infrastructure for AI decisions, aiming to bring traceability and human oversight into AI workflows. It is described as a "seatbelt for AI" and aligned with EU AI Act requirements around human oversight and traceability.
It claims to address the lack of verifiable accountability in AI systems, especially where decisions matter — a concern highlighted by the author’s background in construction, where every structural decision leaves a paper trail.
Evidence
- The tagline: “A cryptographic accountability layer for AI decisions.”
- The inspiration: “AI answers instantly — but when a decision matters, 'who is accountable and on what evidence?' has no verifiable answer.”
- Alignment with EU AI Act requirements.
- Mention of pilot integrations in regulated workflows (finance, construction compliance).
Inference The positioning reflects a niche focus on regulatory compliance and high-stakes decision-making environments. It does not claim broad market applicability or general-purpose use.
Target Customer & ICP
The description implies that the target customer is regulated industries, particularly those requiring human oversight and traceability, such as finance and construction compliance.
It also mentions an intent to support third-party auditors through a verification tool, suggesting a role for external stakeholders in validating decision trails.
Evidence
- “Pilot integrations for regulated workflows (finance and construction compliance)”
- “Auditor-facing verification tool so third parties can independently verify any decision trail.”
Inference The ICP appears to be organizations or regulators requiring AI accountability, not general consumers or developers. No evidence of end-user customers or B2B clients is provided.
Business Model & Pricing Evidence
There is no evidence in the description of a business model or pricing structure.
Evidence
- No mention of monetization strategy.
- No indication of customer acquisition or revenue streams.
- No pricing information, subscriptions, or licensing models are described.
Inference The project is currently in prototype form and has not yet developed a commercial framework. It may be early-stage, possibly pre-revenue.
Technical & Delivery Signals
The description includes several technical details about how the system was built:
- Built with Codex, GPT-5.6, Node.js, JavaScript, HTML, and OpenAI API
- Uses Ed25519 signatures for per-block verification
- Implements SHA-256 hash chains
- Includes a verifier function (verifyChain) with deterministic serialization
- Demonstrates tamper detection via signature failure on specific blocks
It also mentions that the system was built in a 3-day hackathon, by a solo founder working evenings and weekends.
Evidence
- Implementation details: “verifyChain()”, “deterministic payload serialization”
- Commit history shows session-by-session development
- Demo includes tamper tests with block-specific error messages
Inference The technical implementation is functional but likely not production-ready. The solo founder’s constraints suggest a limited scope and experimental nature.
Traction & Maturity Signals
There is no evidence of traction or adoption beyond the hackathon demo.
Evidence
- No customers, users, or pilot deployments are mentioned.
- No revenue, ARR, or headcount data provided.
- The project was built in a 3-day hackathon by one person.
Inference The system is at a very early stage — likely a prototype with no commercial traction. It has not moved beyond the demonstration phase.
Competitive Context
There is no evidence of competitors or competitive positioning in the description.
Evidence
- No mention of existing solutions addressing AI accountability.
- No comparison to other tools or platforms in the space.
Inference It is unclear whether this is a novel concept or one that overlaps with existing AI governance, explainability, or audit tools. The lack of competitive context makes it difficult to assess its differentiation or market relevance.
Key Risks & Red Flags
Several key risks and red flags are evident from the description:
- Solo founder with no team: A single-person operation may limit scalability and development speed.
- Prototype-only status: No production deployment, customer feedback, or real-world use cases.
- No commercial traction or revenue: The project is described as a hackathon effort, not a business in progress.
- Unverified claims: All statements are self-reported; no independent validation of functionality or impact.
- Limited technical depth: While cryptographic elements are mentioned, the system appears to be a proof-of-concept rather than a robust infrastructure solution.
Inference The project is at a very early stage and may not yet have a viable path to commercialization without significant development and traction.
Diligence Questions To Ask The Founders
- What specific use cases or industries are you targeting for pilot integrations, and what is the timeline for those?
- How do you plan to scale beyond a single-person development model?
- Have you validated any of the technical claims (e.g., signature verification, tamper detection) with external parties or in real-world conditions?
- What is your long-term vision for monetization and product-market fit?
- Are there any existing partnerships or early adopters in regulated industries like finance or construction?
- How do you intend to address potential performance or latency issues in a production AI decision pipeline?
Investment/Partnership Verdict
Not evidenced
The description provides no information about revenue, customers, traction, or financials. It describes a prototype built during a hackathon by one person with no confirmed commercial activity.
Confidence Level Very low
Risk Rating
High (due to lack of evidence for viability, traction, or scalability)
Inference This is an early-stage idea with strong technical claims but no demonstrated path to market. It may be suitable for early-stage investment if the founder can demonstrate progress toward pilot integrations and a clear commercial strategy, but as described, it lacks sufficient evidence to support a due-diligence conclusion.
