Next-Gen Data Transport Standard

The ultra-compact, cryptographic data transport & identity layer

DTL (Domain Transport Language) combines ultra-compact serialization, cryptographic security, and Web3 integration for AI systems, critical infrastructure, and decentralized identity. DTLAuth replaces JWT, SAML, and OIDC with deterministic, cryptographically sealed tokens.

Core Features

What makes DTL revolutionary

🧬

Schema-Driven

Every table declares fields and types inline. Deterministic validation, zero ambiguity, self-describing format.

🔐

Cryptographically Sealed

BLAKE3-256 hashing, Ed25519/secp256k1 signatures, row-chain integrity. One bit changes = instant detection.

⛓️

Web3-Native

Wallet-bound signatures, blockchain anchoring, verifiable proofs. Perfect for decentralized identity and DeFi.

📦

Ultra-Compact

40-60% smaller than JSON equivalents. Ideal for bandwidth-constrained IoT, edge, and satellite systems.

🛡️

No Ambiguity

Unlike XML/SAML, single canonical form. No namespace tricks, no whitespace exploits, no alg=none bugs.

🚀

Easy Integration

Simple to parse in any language. Python/TypeScript/Go SDKs, CLI tool, FastAPI gateway. Minimal dependencies.

Security Modes & Domain Codes

Flexible per-table configuration with locked domain registry

Security Modes (S)

Mode Description
S0 No extra security (inherits file defaults)
S1 Row-level hashing (BLAKE3-256)
S2 Row-level hashing + encryption (reserved)

Web3 Modes (W)

Mode Description
W0 No Web3 integration
W1 File-level digital signature (wallet-bound)
W2 Row-level digital signatures

Domain Codes

Code Domain Use Case
dtHC Healthcare EHR, HIPAA, clinical workflows
dtFN Finance Transactions, compliance, audit trails
dtIOT IoT & Sensors Time-series, edge computing
dtAI AI & ML Training data, model pipelines
dtID Identity & Auth DTLAuth tokens, federation
dtWEB Web & APIs REST, microservices, gateways

DTLAuth: Modern Identity Tokens

Replace JWT, SAML, OIDC with deterministic, cryptographically sealed tokens

🎫

ID Tokens (dtID)

User identity, roles, audiences, metadata. Deterministic format, hashed, signed, and verifiable.

🔑

Access Tokens (dtAC)

Scope and resource permissions for APIs, gateways, and microservices. Cross-cloud, cross-chain capable.

🏗️

DTLAuth Gateway

Reference implementation (FastAPI). Drop-in replacement for Keycloak, Auth0, Okta. Federation-ready.
