Sharding is not a new technique and has been used in distributed databases for scalability such as MongoDB and MySQL.
The key idea behind sharding is to split up the tasks into multiple chunks that are then processed by multiple nodes.
How Splitting the Network Dramatically Increases Speed
This results in improved throughput and reduced storage requirements.
In blockchains, a similar scheme is employed whereby the state of the network is partitioned into multiple shards.
The state usually includes balances, code, nonce, and storage.
Shards are loosely coupled partitions of a blockchain that run on the same network.
There are a few challenges related to inter-shard communication and consensus on the history of each shard.
Why This Matters for Blockchain Technology
Understanding Sharding is not just an academic exercise — it has real-world implications for how blockchain systems are designed, deployed, and secured. Whether you are a developer building decentralized applications, a business leader evaluating blockchain adoption, or a curious learner exploring the technology, this knowledge provides a critical foundation.
