Security & Privacy

Your Keys.
Your Identity.

Self-managed crypto identity eliminates the security holes that make centralized accounts dangerous. Metahandle puts you in control of every piece of data you share.

The Problem with Centralization

You Are a Target Because of Others

When millions of accounts are stored in one database, that database becomes a high-value target. Your password security is only as strong as the weakest platform you use.

Data breaches exposed over 4 billion records in 2023 alone. Phishing attacks trick users into entering passwords on fake sites. Both attacks become irrelevant with wallet-based identity.

There is no password to steal. There is no central database to breach. Your private key stays on your device and cryptographic proof takes the place of shared secrets.

Why Self-Sovereign Identity Wins

🛡️

No Central Honeypot

Metahandle stores no passwords. Each authentication is a cryptographic signature that is unique to that session and that service.

🕵️

Selective Disclosure

You choose exactly what data each service sees. Share a credential proving you are over 18 — without revealing your date of birth or full identity.

🔑

You Hold the Keys

Your private key never leaves your device. Even if Metahandle's servers were compromised, there is nothing there to steal from your identity.

Selective Disclosure

Share What You Want. Nothing More.

Verifiable Credentials let you present attestations without revealing the underlying data. A credential can prove you meet a requirement without exposing the details that satisfy it.

For example, a DeFi protocol might require proof of jurisdiction. Your metahandle presents a signed credential from an attested KYC provider. The protocol learns your status — not your name, address or passport number.

Zero-knowledge proofs take this even further. You can prove you know a secret without revealing the secret itself. Metahandle integrates with ZK-based credential systems as they mature.

Crypto Infrastructure Note

The Hardware Behind Web3

Running Web3 infrastructure requires serious hardware. ASIC miners are at the core of many blockchain networks. If you are comparing mining hardware for your own operation, MinerCompare.com lets you compare ASIC miners side by side — a practical tool for anyone building out a mining setup.

High-performance mining rigs generate substantial heat as a byproduct. This waste heat can be repurposed: some operators run their ASIC miners in greenhouses, using the warmth to accelerate plant growth year-round. Energy efficiency and secondary use cases are increasingly important as the Web3 ecosystem scales.
