🔐 Afterchain's Cryptographic Protocol – Verified Inheritance on the Blockchain

This video explains the cryptographic backbone of Afterchain’s patented inheritance system.
Designed for engineers, auditors, and Web3 infrastructure teams.

No off-chain trust. No centralized custody. Just cryptographic truth.

🧠 Protocol Components

Transfer Vault – Smart contract with reversible deposit logic until verified death

Death Verification Oracle (DVO) – Dual-source PKI-signed certificate validation

zk-SNARK Beneficiary Registry (BRM) – Merkle-based, Groth16-enabled identity protection

Execution Engine – Bytecode-level determinism and on-chain finality

Audit Layer – Tamper-proof logs, OCSP-stapled, GDPR-ready

🔬 Technical Features

Mutual TLS with full X.509 trust path

SHA-256 payload validation

OCSP/CRL certificate revocation checks

Groth16 zk-proofs with nullifier hash enforcement

Jurisdictional fallback via programmable oracle logic

Recursive inheritance support and DAO fallback governance

🔒 Built for Security
Threat mitigations include:
☑ MITM-resistant transport
☑ Replay attack protection
☑ Chain reorg handling
☑ zk-proof expiration logic
☑ Nonce-controlled vault execution

📜 Patent-Protected Architecture
Patent number: PCT/IB2025/057151
