🌐 What is Blockchain? Blockchain is a technology that stores data in the form of blocks that are interconnected. Each block contains information and is linked to the previous block. #Blockchain #Crypto
🔗 Each block also has a ‘hash’, which is a unique code generated from the data in that block. This hash serves to identify the block and ensure data integrity. If the data changes, the hash will change too! #Hash #Security
📚 Additionally, each block stores the hash of the previous block. This creates a secure chain because if someone tries to change one block, all subsequent blocks must also be changed. #Chain #Integrity
🔍 Let’s start with ‘blocks’. Each block in a blockchain contains transaction data, such as who sent, who received, and how much was transferred. It’s similar to a record in a ledger. #Data #Transactions
