On-Chain Attestation Reports vs Off-Chain PDF Reports

Tamper-proof record: Once published, attestation data (e.g., from EAS or Verax) is anchored on a public ledger like Ethereum or Base. This provides cryptographic proof of a report's existence and integrity at a specific time. This matters for regulatory compliance and investor due diligence, where proof cannot be disputed.

Machine-readable attestations: Reports are structured data (e.g., JSON schemas) that smart contracts and dApps can query and act upon. This enables automated workflows like loan approvals based on real-time audit scores or integration with DeFi risk engines like Gauntlet. Off-chain PDFs create data silos.

Universal compatibility: PDFs are the de facto standard for legal, financial, and regulatory submissions. They are immediately actionable for traditional stakeholders (banks, non-crypto VCs, auditors) without requiring blockchain infrastructure. This matters for bridging to legacy systems and current legal frameworks.

Zero gas fees: Generating and distributing a PDF has negligible marginal cost, unlike on-chain transactions which incur network fees (e.g., $5-$50 on Ethereum L1). The tooling (e.g., LaTeX, DocuSign) is mature and requires no blockchain expertise. This matters for high-volume, low-value reports or teams with limited Web3 dev resources.

Permanent Record: Once published (e.g., via EAS on Ethereum or Verax on Base), the report's hash is immutable. This matters for regulatory compliance (proof of audit) and DAO governance, where proposals require tamper-proof evidence. Verification is trustless via any block explorer.

Smart Contract Integration: Attestations can be queried on-chain by other protocols. This enables automated workflows like a lending protocol checking for a valid audit before listing a token, or a governance vault requiring a KYC attestation. It unlocks composability within the DeFi stack.

Negligible Publication Cost: No gas fees required for storage or distribution. This matters for lengthy, complex reports (100+ pages) with detailed charts and code snippets that are impractical to store on-chain. Ideal for internal reviews and traditional stakeholder distribution via email or websites.

Full Control Over Access: Reports can be gated, versioned, and revoked without an on-chain transaction. This matters for sensitive pre-launch audits or reports containing proprietary information. Formats (PDF, DOC) are universally accessible without needing a wallet or RPC connection.

Instant Public Availability: The moment an attestation is minted, it's globally visible. This matters for building user trust at scale, as anyone can independently verify a project's claims (e.g., 'audited by Chainscore') without relying on a central website that could be hacked or taken down.

Rich Formatting & Media: Supports complex layouts, embedded images, and hyperlinks that are impossible in a standard on-chain attestation schema. This matters for detailed technical explanations where visual callouts on code vulnerabilities or architectural diagrams are critical for developer understanding.

Tamper-proof record: Once written to a ledger like Ethereum or Solana, the report's hash is permanently verifiable by anyone. This matters for audit trails, regulatory compliance (e.g., Proof of Reserves), and trustless verification in DeFi protocols.

Smart contract integration: Attestations using standards like EAS (Ethereum Attestation Service) or Verax can be queried and acted upon by other contracts. This matters for automating workflows, building credential-based access (e.g., gated NFTs), and creating on-chain reputation systems.

Transaction overhead: Each attestation requires gas fees and is bound by blockchain finality times (e.g., ~12 sec on Ethereum L2s). This matters for high-frequency reporting (e.g., per-second metrics) or applications with thousands of low-value attestations, where costs become prohibitive.

Zero publishing cost: Generate and distribute reports via traditional web servers or cloud storage (AWS S3, IPFS). This matters for legacy financial reporting, internal dashboards, or any high-volume documentation where on-chain costs are unjustified.

Unlimited data density: Support charts, tables, and complex visualizations that are impossible or impractical to encode on-chain. This matters for detailed financial statements, lengthy legal documents, or marketing materials requiring human-readable presentation.

Verification dependency: Authenticity relies on a publisher's signature or hosted hash, creating a single point of failure. This matters for high-stakes scenarios where the hosting entity could alter or revoke the document, undermining the report's credibility.
