Definition
A method of scaling blockchain networks by splitting the database into small pieces (shards) to process transactions in parallel.

Key Takeaways
1
Sharding splits the blockchain database into parallel processing segments called shards
2
Each shard has its own validators handling its own portion of data
3
Network capacity scales linearly with the number of shards added
4
Cross-shard communication is the main technical challenge to solve
Practical Example
Instead of 10,000 nodes all processing the same 1,000 TPS, 64 shards of ~156 nodes each can theoretically process 64,000 TPS in parallel - dramatically increasing throughput.
