what is blockchain technology
What Is Blockchain Technology? Blockchain technology is the technology that allows Bitcoin to work. But few people really understand how it works. Today, weâre explaining what it is and how it makes Bitcoin tick. The blockchain is like a public ledger of all Bitcoin transactions that have ever been executed. The blockchain is constantly growing with every Bitcoin transaction. Every time a Bitcoin transaction is executed, a completed âblockâ is added onto the blockchain. Thatâs where the word âblock chainâ comes from.
