Decentralized Identity Wallet (DID)

Tychi Wallet introduces an integrated Decentralized Identity (DID) system that allows users to manage, verify, and share digital identities securely—without reliance on centralized authorities.

✅ DID Standards

Tychi adheres to globally recognized DID frameworks such as W3C specifications. Each DID is self-sovereign and cryptographically bound to the user.

---

🔐 Cryptographic Proofs

We leverage Elliptic Curve Cryptography (ECC) to generate and verify proofs of ownership. This ensures identity integrity, tamper resistance, and verifiability.

---

🪪 Verifiable Credentials (VCs)

Users can issue and present credentials (e.g., degrees, licenses) directly from their wallet.

• Self-signed using private keys

• No third-party validation required

• Used in DApp interactions and verification workflows

---

🧠 Key Management

• Hierarchical Deterministic (HD) wallets securely manage identity keys.

• Integrated social recovery and multi-sig access strengthen key resilience.

---

🔓 User Authentication

Combines three-factor authentication (3FA):

• Biometric verification (face/fingerprint)

• Password/passphrase

• OTP-based device login Ensures only verified users can access identity data.

---

🌐 Web3 Integration

• DApps can request identity verification directly from the wallet.

• Smart contract–based attestations streamline onboarding across platforms.

---

🛡️ Privacy Features

• Zero-Knowledge Proofs (ZKPs) allow users to prove identity traits without revealing full details.

• Users maintain full control over what is shared and with whom.

🧭 Example Workflow

1. User creates a DID and issues verifiable credentials via Tychi Wallet.

2. A DApp requests verification of a credential.

3. The DApp queries the blockchain to validate the associated DID.

4. Tychi verifies and returns a ZKP-based attestation.
