Enterprise-grade data integrity
VeilChain provides cryptographic guarantees for your data without the complexity of blockchain. Built on battle-tested Merkle tree technology.
Everything you need for tamper-proof data
Append-Only Storage
Data can never be modified or deleted once added. Every entry is cryptographically chained to the previous entries, making tampering mathematically detectable.
- Immutable by design - no backdoors
- Cryptographic chaining prevents reordering
- Position-binding prevents insertion attacks
Cryptographic Proofs
Generate compact O(log n) proofs that any entry exists in the ledger. Proofs can be verified offline, anywhere, by anyone - no need to trust VeilChain.
- Logarithmic proof size (efficient even at scale)
- Offline verification capability
- Third-party verifiable without API access
External Anchoring
Publish root hashes to Bitcoin, Ethereum, or Certificate Transparency logs. Create irrefutable proof of your data's existence at a specific point in time.
- Bitcoin anchoring for maximum decentralization
- Ethereum smart contract integration
- RFC 6962 CT log compatibility
Self-Hostable
Run VeilChain on your own infrastructure. Full control over your data with no vendor lock-in. Deploy with Docker in minutes.
- Single Docker container deployment
- PostgreSQL or SQLite storage backends
- No external dependencies required
Lightning Fast
No mining, no consensus delays. Append entries instantly with immediate proof generation. Verification takes less than 10ms regardless of ledger size.
- Sub-millisecond append operations
- Instant proof generation
- O(log n) verification time
Developer Friendly
TypeScript SDK with full type safety. REST API with OpenAPI documentation. Integrate in minutes with any tech stack.
- TypeScript/JavaScript SDK
- REST API with JSON responses
- Webhook support for real-time events
Built for security-critical applications
SHA-256 Hashing
Same algorithm that secures Bitcoin and millions in cryptocurrency
API Key Auth
Scoped API keys with granular permissions per ledger
TLS Encryption
All data encrypted in transit with TLS 1.3
SOC2 Ready
Designed for compliance with SOC2, HIPAA, and GDPR
Audit Trail
Complete API access logs for security monitoring
Idempotency
Request deduplication prevents accidental double-writes
