🔟 Blockchain: what is it?
⛓️ Blockchain explained simply
Imagine a digital ledger shared among many computers.
Transactions are recorded in this ledger and grouped into blocks.
These blocks are then linked together: that's the blockchain.
Bitcoin uses a blockchain, but Bitcoin and blockchain are not the same thing.
📌 Bitcoin = a cryptocurrency
📌 Blockchain = a technology used, among other things, to record transactions
