As the global supply of Bitcoins reaches its 21 million coin limit, transaction fees will become the primary method for miners to earn Bitcoins.

Instead, the previous block’s hash appears within the new block. If the most minute detail had been altered in the previous block, that hash would change. Even if the alteration was 20,000 blocks back in the chain, that block’s hash would set off a cascade of new hashes and tip off the network. Another name for a blockchain is a “distributed ledger,” which emphasizes the key difference between this technology and a well-kept Word document.
