We all know what the blockchain is and how it is related to bitcoin or other cryptocurrencies, but how would you define it to someone who has never heard the word 'blockchain'?
Here is one I find easy
' The blockchain is a global and decentralized ledger that stores information about a transaction and also verifies the data'
What is you own favorite definition or explanation?
Blockchain is a growing list of records, called blocks, which are linked using cryptography. Blockchains which are readable by the public are widely used by cryptocurrencies. Private blockchains have been proposed for business use.
