Introduction to Blockchain Wallets
In blockchain technology, one of the most critical components directly interacting with users is the wallet. Wallets enable users to:
- Access on-chain funds
- View account addresses
- Execute transactions like transfers
Unlike physical wallets, blockchain wallets don't store currency. Instead, they:
- Manage cryptographic keys (public/private key pairs)
- Provide authentication for blockchain transactions
- Serve as gateways to decentralized applications (DApps)
Key Wallet Concepts
| Concept | Description |
|---|---|
| Private Key | Cryptographic proof of ownership (like a bank PIN) |
| Public Key | Derives your blockchain address (like account number) |
| Seed Phrase | Human-readable backup for key recovery (12-24 words) |
