Ever wondered what makes Bitcoin tick? Here's the breakdown: Bitcoin operates on a decentralized network where transactions get bundled into blocks. These blocks are cryptographically linked together in chronological order—that's your blockchain. Miners compete to solve complex math puzzles, validating transactions and securing the network. When a miner cracks the puzzle, they get to add the next block and earn Bitcoin as a reward. This process, called Proof of Work, makes it virtually impossible to tamper with past transactions. The beauty lies in its transparency: everyone can verify every transaction, yet no single entity controls the system. That's decentralization at work. No banks, no intermediaries—just pure peer-to-peer value transfer secured by mathematics and consensus.
