# Federated Matching Process

The SyncID Federated Identity Matching process enables the system to match a user’s collective identity data (biometrics, social accounts, and blockchain addresses) against a broader database of credentials to verify identity across multiple platforms. Upon user authorization, the system uses MPC to encrypt web2 identifiers securely to allow any blockchain, Layer 3 applications (L3s), and decentralized apps (DApps) to securely identify users without revealing privacy.

Let's understand it through an example:\
Bob and Alice are both registered on SyncID. Their identities include the following attributes:

```
{
  "Bob": {
    "ADA_Address": "enc_9a7f1c8d3b72...",
    "Twitter_ID": "enc_f1e2d3a4b5c6...",
    "Telegram_ID": "enc_12b6f8a3d2e1...",
    "Biometric_Hash": "enc_56d8b1f4e2a3...",
    "ETH_Address": "enc_ab12cd34ef56...",
    "Solana_Address": "enc_ef12bc34ab56...",
    "WhatsApp_ID": "enc_7d1e2f3b4c8a...",
    "SHA256_Hash": "enc_34d8a1f6b9e2..."
  }
},

{
  "Alice": {
    "ADA_Address": "enc_a9f2e4d7b9c3...",
    "Twitter_ID": "enc_b1d2e3f4a5c6...",
    "Telegram_ID": "enc_c8f3d7a2e4b1...",
    "Biometric_Hash": "enc_d6b8f1e3c2a4...",
    "ETH_Address": "enc_fa23bc45de67...",
    "Solana_Address": "enc_ae34df56bc89...",
    "WhatsApp_ID": "enc_1f2d4e6b7c9a...",
    "SHA256_Hash": "enc_7b3d1f9e2a6b..."
  }
}

```

Bob and Alice can now seamlessly pay or chat with each other on Sync Mobile app or Telegram or Whatsapp, tip on Twitter using SyncID-linked social profiles, receive notifications from dApps they interact with and much more without the need of blockchain addresses. All from a single sybil resistant identity.

> For example: You can request or send any token to WhatsApp/Telegram/Twitter/Discord accounts (easily resolvable to any cross-chain address via SyncID) without compromising the user's privacy.

This system empowers users to interact seamlessly across multiple platforms including whatsapp, telegram, etc., from sending tokens to chatting with others, without revealing sensitive information or relying on traditional blockchain addresses. SyncID links biometric data, social profiles, and blockchain identities, creating a unified, privacy-preserving solution that allows for secure, cross-chain interactions.
