# ChainIT > Verification-native infrastructure that converts authoritative real-world facts into cryptographically sealed, machine-consumable state for enterprises, regulators, auditors, counterparties, and AI agents. Truth Over Trust. Trust Nothing. Verify Everything. Key concepts: a VDT is a source-verified, lifecycle-aware, machine-consumable proof object. Token Grade is a machine-readable assurance score reflecting verification depth and revocation state. ChainIT records lifecycle changes append-only, so history is preserved while current validity stays queryable. ## Platform (Verified State) - [Validated Data Tokens](https://chainit.com/product/data-tokenization/): cryptographically sealed verified state for identities, organizations, assets, devices, events, and agreements - [ChainIT ID](https://chainit.com/product/identity-verification/): verified human identity combining biometric liveness, government-ID validation, device context, and selective disclosure - [ChainIT Organization ID](https://chainit.com/product/business-verification/): machine-queryable organizational identity and authority graph verified against government registries - [BeingID](https://chainit.com/product/identity-scoring/): human-assurance layer grading liveness and identity confidence across ten levels - [Token Grade](https://chainit.com/product/token-grading/): assurance signal reflecting verification depth, source quality, lifecycle continuity, and revocation state - [Touch Audit](https://chainit.com/product/audit-trail/): inspectable proof surface exposing who, what, when, where, device, authority, and lifecycle status behind any VDT - [ChainIT Check](https://chainit.com/product/chainit-check/): independent validation of VDT status, provenance, and integrity at the point of reliance, via QR or API ## Execution - [Pactvera](https://pactvera.com/): governed execution layer binding verified identity, deterministic rules, tokenized consideration, and immutable final proof into agreements - [Business Rules Engine](https://chainit.com/product/business-rules-engine/): deterministic, versioned policy rules and jurisdictional constraints applied at execution time - [ChainIT Pay](https://chainitpay.com/): identity-verified payments and payouts across card, bank, instant, wallet, and stablecoin rails in 200+ countries - [ChainIT KYB](https://chainit.com/product/kyb-solution/): automated business verification covering registration, ownership, officers, and regulatory standing - [ChainIT KYC](https://chainit.com/product/kyc-aml-compliance/): individual identity verification with liveness, watchlist screening, and AML compliance - [ChainIT X](https://chainit.com/product/online-marketplace/): commerce framework applying VDTs, Pactvera, and ChainIT Pay to marketplace and microsite transactions ## AI & Agentic Commerce - [ChainIT Platform Overview](https://chainit.com/): VDTs as verified AI endpoints — deterministic state anchors AI agents can consume before reasoning, routing, or execution - [API Documentation](https://sdk.chainit.online/docs/intro): machine-readable proof state for enterprise platforms, orchestration engines, and AI agents ## Applications - [Age App](https://www.ageapp.com/): privacy-preserving age and identity verification for age-restricted digital and physical environments - [Sportafi](https://www.sportafi.com/): verified identity and eligibility platform for sports and athletics ## Developers - [API Docs](https://sdk.chainit.online/docs/intro): authentication, requests, and response objects - [SDKs](https://sdk.chainit.online/): developer SDK suite for integrating biometric validation, VDT issuance, and compliance logic - [Webhooks](https://sdk.chainit.online/developer/auth/qrCode): event notifications for verification and lifecycle changes ## Optional - [About ChainIT](https://chainit.com/about-us/): company background, zero-trust architecture principles, and patent portfolio - [Blog](https://chainit.com/insights/): articles on KYC, KYB, AML, and verification practices - [Support Center](https://support.chainit.com/): guides, release notes, SLAs, and FAQs - [Contact](https://chainit.com/contact-us/): sales and technical architecture review requests - [Privacy Policy](https://chainit.com/privacy-policy/): data handling practices - [Biometric Policy](https://chainit.com/biometric-policy/): biometric data collection and retention policy
