When crypto people talk about "ledger," they could mean two very different things, and the context usually makes it clear which one. There's the blockchain ledger – the distributed record of all transactions – and Ledger the company that makes popular hardware wallets. Both are crucial to crypto, but in completely different ways.
The blockchain ledger is essentially crypto's accounting book, recording every transaction that's ever happened on the network. Unlike traditional ledgers controlled by banks, blockchain ledgers are distributed across thousands of computers worldwide, making them transparent, verifiable, and nearly impossible to manipulate.
Then there's Ledger (capital L), the French company behind Nano S and Nano X hardware wallets. When someone says "I keep my crypto on a Ledger," they're talking about these physical devices that store private keys offline, providing security against online hackers. Fair warning: Ledger the company has had some controversy around data breaches and firmware updates, so do your research.
When Do You Use Ledger?
You'll see ledger discussions in two main contexts:
- Blockchain ledgers: explaining how distributed systems work, discussing transparency and immutability
- Ledger devices: comparing hardware wallet options, discussing security best practices, and self-custody recommendations
The term appears in educational content about blockchain basics, security discussions about protecting crypto assets, and technical explanations of how cryptocurrencies maintain accurate balances without central authorities.
