How Does Cryptocurrency Work?
Creating a Digital Wallet
A digital wallet stores your cryptocurrency and can be created via specialized apps or web-based platforms. Each wallet contains:
- Public key: Your receiving address (like an account number)
- Private key: Your secure signature for transactions (like a password)

Blockchain Recording
Approved transactions become:
- Immutable: Permanently recorded on the blockchain
- Transparent: Publicly verifiable without revealing identities
Mining Incentives
Miners earn crypto rewards by:
- Solving complex mathematical problems
- Adding verified blocks to the chain
- Maintaining network security
