💡 WHAT IS A BLOCKCHAIN? The blockchain is the reason why cryptocurrency is so secure. Simply put, imagine that each transaction made (whether deposit, withdrawal or anything else) is a block. In each block, you have not only the details of that transaction, but of the one before it. That’s why it’s called a blockchain. This is why it’s tamper-proof. Because everyone can access this and it is easy to spot discrepancies. Because if they wanted to alter one block, say BLOCK B, they would need to alter BLOCK A which comes before it as well, because the information is there as well, and the one after it, BLOCK C — because that also contains information on BLOCK B. And it goes on and on.
The blockchain is sort of like a super-advanced ledger on steroids that keeps track of transactions in a simple and effective way.
