Imagine a highway with 1 lane = traffic jam. Now imagine 10 lanes = smooth, fast driving.
That’s what sharding does for blockchains. It splits the network into smaller lanes (shards) so many transactions can happen at the same time — making it faster, cheaper, and scalable.
Why it matters
Speeds up big blockchains
Helps support millions of users
Key for future projects like ETH 2.0
Scalability = Success. Sharding makes it possible.
