Crypto Ledger
A crypto ledger is basically a record of all transactions in a cryptocurrency system—but unlike a traditional bank ledger, it’s decentralized and tamper-resistant.
Here’s the simple breakdown:
1. What it is
- A crypto ledger (usually called a blockchain) is a digital record of transactions
- It tracks who sent what amount of cryptocurrency to whom
- It’s shared across many computers (nodes), not controlled by a single authority
2. How it works
- Transactions are grouped into blocks
- Each block is linked to the previous one → forming a chain
- Once added, data is extremely hard to change (immutable)
3. Why it matters
- Transparency: Anyone can view transactions (on public blockchains)
- Security: Cryptography protects data
- Trustless: No need for banks or middlemen
4. Example
If you send Bitcoin:
- The transaction is broadcast to the network
- Verified by miners/validators
- Added to the blockchain ledger
- Becomes permanent record
5. Types of crypto ledgers
- Public (permissionless) – e.g., Bitcoin, Ethereum
- Private (permissioned) – used by companies or institutions
