"Don't trust ProofCore. Verify the mathematical proof yourself."

ProofCore is not a centralized SaaS notary. It is a cryptographic commitment protocol designed to bridge human communication, DevOps release chains, and autonomous AI agents with the TON Blockchain.

• Payload Integrity (SHA-256): Verifies the raw bytes have not changed.
• Batch Inclusion (O(log N) Merkle Trees): Proves an individual item belongs to an anchored batch without requiring access to other batch data.
• Timestamped Existence: Anchors the root cryptographic commitment into an immutable TON Blockchain block transaction.
• Zero-Storage Architecture: Raw user files and private datasets are never stored on-chain. Only the 64-character Merkle Root is committed publicly.

pip install proofcore

from proofcore import seal, verify

# 1. Seal an artifact anonymously (Zero-Auth / Zero-Storage)
receipt = seal(
    content="Security Audit: Vault.sol passed with 0 Critical issues.",
    agent_id="Claude-3.5-Sonnet",
    title="Vault.sol Audit Report"
)
print(f"Verified URL: {receipt['verification_url']}")
print(f"Citation Badge: {receipt['citation']}")

# 2. Programmatically verify authenticity (M2M)
result = verify(
    deal_id=receipt["deal_id"],
    content="Security Audit: Vault.sol passed with 0 Critical issues."
)
assert result["valid"] is True

Run instantly without installation:

# Claude Code CLI
claude mcp add proofcore https://mcp.proofcore.org

Or add to your .cursor/mcp.json / claude_desktop_config.json:

{
  "mcpServers": {
    "proofcore": {
      "url": "https://mcp.proofcore.org"
    }
  }
}

Automatically hash compiled release binaries on GitHub runners and anchor them to TON:

name: Release & Notarize

  release:
    types: [published]

permissions:
  id-token: write # Required for Cryptographically Proven GitHub OIDC Identity
  contents: read

jobs:
  notarize:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - name: ProofCore Notary
        uses: ProofCore-Protocol/proofcore-action@v1
        with:
          files: "dist/*.tar.gz, dist/*.whl"
          title: "Release ${{ github.ref_name }}"

Every proof anchored by the protocol can be exported into an air-gapped, self-contained Evidence Archive (GET /api/download/{deal_id}):

• 1. Asset Digest:

  H_asset = SHA256(raw_bytes)
  

• 2. Metadata Digest:

  H_meta = SHA256(forensics_json_bytes)
  

• 3. Combined Deal Hash:

  H_deal = SHA256( (H_asset_1 + ... + H_asset_n + H_meta).encode('utf-8') )
  

• 4. Tree Traversal: For each sibling in merkle_path:
  • direction == 'left' ➔ H_next = SHA256( (sibling + H_current).encode('utf-8') )
  • direction == 'right' ➔ H_next = SHA256( (H_current + sibling).encode('utf-8') )

• 🇺🇸 US Federal Rules of Evidence (FRE 902): Rule 902(14) establishes that electronic data authenticated by a certified digital identification process (cryptographic hash) is self-authenticating in judicial proceedings.
• 🇪🇺 EU eIDAS Regulation (EU No 910/2014): Article 41(1) recognizes electronic time stamps as legally admissible evidence, prohibiting denial of legal effect solely due to electronic form.
• ⚖️ The "Proof is Not Truth" Distinction: ProofCore cryptographically certifies Integrity (bytes match), Inclusion (belongs to the batch), and Existence (anchored at time T). It does not evaluate the factual truthfulness of the underlying claims.
