DTL Core Advantages
Why enterprises, healthcare, fintech, and Web3 choose DTL
Ultra-Compact
40-60% smaller than JSON. Aster Hospital ER Bundle: 7.9 KB in DTL vs 20 KB in JSON. Perfect for IoT, edge computing, bandwidth-constrained systems, and satellite networks.
Schema-Driven
Schema declares inline. Every table announces its fields and types. Zero ambiguity, deterministic validation, no silent failures. Self-describing format.
Cryptographically Sealed
Security built-in. BLAKE3-256 hashing, Ed25519/secp256k1 signatures, row-level integrity. One bit changes? Instant detection. No post-hoc signing.
Web3-Native
Blockchain anchoring included. Wallet-bound signatures, ZettaChain integration, Ethereum/Polygon support. Perfect for decentralized identity and DeFi.
No Parsing Exploits
Single canonical form. Unlike XML/SAML, zero namespace tricks, no whitespace exploits, no alg=none vulnerabilities. Deterministic always.
Fast & Simple
Trivial to parse. Line-based format, pipe separators, minimal regex. Parse in <50 lines of Python/Go/TypeScript. Zero vulnerable dependencies.
Audit Trail Ready
System tables included. HASH_* for integrity, SIG_* for signatures, CHAIN for blockchain. Built-in compliance and forensics.
Multi-Domain
Domain codes locked. dtHC (Healthcare), dtFN (Finance), dtIOT (IoT), dtAI (AI/ML), dtID (Identity). Extensible, future-proof.

Security: Why DTL Wins
Cryptographic advantages
1. Row-Level Hashing (S1 Mode)
Every row generates a BLAKE3-256 hash for integrity verification. One bit changes? Hash fails. Instant detection of tampering.
2. Row-Level Signatures (W2 Mode)
Individual rows cryptographically signed with Ed25519/secp256k1. Non-repudiation: signer cannot deny signing specific records.
3. File-Level Signature (W1 Mode)
Entire file signed with wallet's private key. Wallet-bound identity. Perfect for decentralized systems.
4. Blockchain Anchoring
File hash anchored to ZettaChain, Ethereum, or Polygon. Immutable proof of existence and timestamp. Verifiable on-chain.
5. No Ambiguity Attacks
Unlike JWT's alg=none or XML namespace tricks, DTL has single canonical form. No signature bypass vulnerabilities.
6. Confidentiality Levels
Data tagged with sensitivity: C0 (Public) → C3 (Restricted). Encryption support (S2 mode reserved). HIPAA/GDPR ready.
