Scope: This note explains the fundamental distinction between a traditional bank ledger and a cryptocurrency shared ledger for readers interested in digital assets.
A bank’s ledger is a single, private record that only the institution can modify.
In contrast, many crypto networks keep a shared ledger duplicated across many nodes; every participant holds the same copy and consensus rules decide any update.
When a user sends crypto, the wallet produces a digital signature.
The network validates that signature and, once approved, all copies of the ledger are updated simultaneously.
Quiz – From the source article: What does a wallet generate to prove the sender’s authority?
Answer: a digital signature, because the article states the wallet signs the transaction and the network checks that signature before acceptance.
Limitation: The explanation covers generic blockchain principles and does not address network‑specific nuances such as proof‑of‑stake validator selection. $BTC $ETH
