Building Trust Through Cryptography
VeilChain makes Bitcoin-grade immutability accessible to everyone, without the blockchain overhead.
Our Mission
In a world where data can be silently altered, trust becomes a luxury. VeilChain exists to change that.
We believe that every organization, regardless of size, should have access to cryptographically verifiable audit logs. Not because regulations demand it, but because trust should be provable.
Our mission is simple: make data integrity mathematically verifiable, not just promised.
Cryptographic Proof
Every entry is mathematically linked. Tampering is not just difficult—it's detectable.
Why VeilChain?
Blockchain Security, Zero Complexity
Merkle trees provide the same cryptographic guarantees as blockchain without consensus mechanisms, gas fees, or network dependencies.
Self-Hostable & Private
Your data stays yours. Run VeilChain on your infrastructure with Docker, or use our managed API. No vendor lock-in.
Developer-First Design
Clean REST APIs, TypeScript SDK, and comprehensive documentation. Integrate in hours, not weeks.
Audit-Ready
Generate inclusion proofs for any entry. External auditors can verify without accessing your data.
// Merkle Tree Verification
const proof = await veilchain.getProof(entryId);
const isValid = veilchain.verify(proof, rootHash);
// isValid: true ✓The Technology
VeilChain is built on sparse Merkle trees—the same data structure that secures billions of dollars in cryptocurrency.
Each entry is hashed with SHA-256 and inserted into an append-only tree. The tree's root hash changes with every addition, creating a chain of cryptographic commitments.
To verify any entry, you only need:
- The entry data
- A logarithmic-sized proof path
- The tree's root hash
No trusted third party required. Just math.
Open Source, Open Future
VeilChain is part of the Trustless Voting System (TVS) initiative—an ambitious project to build verifiable election infrastructure. But the technology isn't limited to voting.
We're building VeilChain as a standalone product because we believe tamper-proof audit logs should be a commodity, not a luxury. Every healthcare system, financial platform, and legal firm deserves access to cryptographic data integrity.
