The Philosophy

Inspired by Ancient Indian Principles

Swatantra

Self-Governance

Your identity belongs ONLY to you.

Satya

Verifiable Truth

Identities must be mathematically provable.

Sutra

Interconnectedness

One identity powers infinite applications without fragmentation.

Nitya

Continuity

Identity evolves over time without changing its root.

A digital identity system built for the next 100 years.

Identity Architecture

Four Interlocking Components

01

ArthaDID Document

Root Identity Layer

Contains

Public keys (Quantum + Classical)
Verification methods
Service endpoints
Version metadata
Face embedding hash
Device signatures
AI agent fingerprints

Uniqueness:

No other chain supports biometric vector-backed identity at protocol level.

02

Decentralized Key System

Hybrid PQC

Contains

Dilithium5 / MLDSA87 (Post Quantum)
Ed25519 (Classical)
Both signatures required
Quantum-immune security
Identity theft impossible

Uniqueness:

Your identity will remain secure even in a quantum-computing future.

03

Identity Vault

Secure Storage Layer

Contains

Profile metadata
Biometric vectors
Device trust scores
Multi-device sync states
ZK-encrypted claims

Uniqueness:

Encrypted storage only. Vector search for biometric match. Proof-of-ownership via ZK circuits.

04

Verifiable Credentials

Privacy-Preserving Proofs

Contains

Proof of Age
Proof of Nationality
Proof of Education
Proof of Employment
Proof of KYC
Proof of Funds
Proof of Humanity

Uniqueness:

All credentials use Zero-Knowledge Attestation. No leak of personal information.

Linked devices
Agent permissions

Outputs

On-chain propagation within milliseconds

Features NO Other Blockchain Has

5 World-First Innovations

Biometric-Enhanced Identity

Face Embeddings

Users can embed biometric vectors (never raw images). Stored securely in SVDB.

Anti-sybil
Account recovery
Multi-factor authentication
AI agent identity linking

Identity for AI Agents

AI-Persona DID

ArthaChain is the first chain to give AI agents their own DID. AI is a first-class citizen.

Own tokens
Sign transactions
Store memory embeddings
Process tasks
Authenticate to apps
Execute workflows

Multi-Device Identity Sync

One DID for Many Devices

Device trust score is recorded in the Identity Vault. Low-trust devices get restricted automatically.

Device trust scoring
Automatic permission restriction
Seamless sync
Security monitoring

ZK-Backed Social Graph

Privacy-Preserving Relationships

No Web2 has this. No blockchain has this.

ZK friend proofs
Anonymous relationship attestations
Interest vectors
SocialFi verifiable stats

DID Layer with Intent Routing

Intelligent Operations

Your DID acts as an intelligent router for intent-driven operations. Protocol-level, not dApp logic.

"Swap $100 ETH to ARTHA"
"Send to my closest verified contact"
"Verify I'm human but not reveal anything else"

5-Layer Security Model

Defense in Depth

1

Quantum Signature Layer

Dilithium + MLDSA provides Quantum immunity

2

ZK Privacy Layer

No raw data, only proofs

3

AI Trust Layer

Identifies malicious identity behaviour

4

Vector Privacy Layer

Face embeddings stored as vector hashes, not images

5

Sharded Redundancy Layer

Identity vault is distributed across shards

Developer Tools

Everything you need to build with DID

DID SDK

Rust, TypeScript, Python, Go

Credential Studio

GUI panel for issuing credentials without coding

ZK Identity Templates

Ready-made circuits for custom KYC/KYB

Face Vector Toolkit

Transform images to biometric embeddings to ZK vectors

DID Wallet Toolkit

QR login, device pairing, biometric unlock, ZK proof requests

The world's first quantum-secure, AI-native, biometric-enhanced identity system that works for humans, devices, and autonomous agents.

It is the foundation of the Intelligent Internet.
