About This Calculator
A blockchain is a shared digital ledger copied across thousands of computers. Transactions are grouped into blocks and linked cryptographically so they cannot be altered after the fact.
Real-world example: Every Bitcoin transaction since 2009 lives on the public blockchain — anyone can verify it, but no one can secretly change it.
