Private keys are the foundation of blockchain security. They enable you to perform verifiable actions directly on-chain without intermediaries.

Here's why they matter:

✓ Full control: You own your transactions and assets outright. No custodian, no delays.
✓ Cryptographic verification: Every action is mathematically signed. It proves you authorized it—and nobody can forge your signature.
✓ Transparency & immutability: Once recorded, transactions are permanent and auditable on the ledger.
✓ Trustless interactions: You don't need to trust a third party; the blockchain verifies everything.

Your private key is essentially your digital signature. Keep it secure—it's the only proof you own your wallet and assets.
