Shard Chains

Shard chains are a way to improve the efficiency of blockchain networks like Ethereum 2.0 by splitting the main chain into smaller, parallel segments called "shards." Each shard processes its transactions independently, reducing congestion and increasing speed. Think of it like multiple lanes on a highway, allowing more cars (transactions) to travel simultaneously without traffic jams. The main chain, or "beacon chain," coordinates these shards, ensuring all parts stay synchronized and secure. This approach helps the network scale better, handle more users, and maintain safety.
