What is a blockchain?
Updated: 2026-10-07 · MarketRadar Whale
A blockchain records transactions in blocks that are chained together. Anyone can view it, yet no one can quietly change it alone.
Why can it be trusted?
The same copy of the ledger is kept on many computers, so a hidden change is not possible.
Uses
Digital money, smart contracts and tracking assets.
