Sharding

Sharding is a database partitioning technique used by blockchain companies. Its goal is scalability, which allows for the processing of more transactions per second. The whole network of a blockchain corporation is divided into smaller sections, or “shards”, by sharding. Each shard is separate and independent from other shards because it is made up of its own data.

Since sharding divides a blockchain network into multiple pieces, it can help networks run more quickly. Sharding, however, raises some security issues because shards are vulnerable to attack.
