Lesson Overview

9.2 – How Mining Secures the Blockchain: Mining provides the defense system that keeps blockchains immutable and tamper-proof. Each time a miner verifies transactions, they create a new block that is cryptographically linked to the previous one. Altering past data would require rewriting the entire chain, which is nearly impossible on a large network. This decentralized verification process eliminates the need for central authorities. Mining also prevents double-spending by ensuring that every coin can only be used once. The result is a self-regulating network where security, transparency, and consensus emerge naturally through computational work.
