The Reasons Behind Sharding

Sharding could help the current limitations that Ethereum’s current features create, such as requiring nodes to get transactions verified. This process makes it all slower and time-consuming, which significantly delays the transactions that can be verified simultaneously. It all comes down to having a scaling problem since the network has a hard time processing the volume of transactions being held. That could change through Sharding.

How Does Sharding Work?

Sharding is a method of splitting, distributing, and storing data among multiple databases. It is necessary when a dataset is too big to be contained in only one database. The main goal of Sharding is to break  all the nodes that work together in Ethereum into smaller groups. These mini-groups are called Shards. In their core, nodes will verify the history of the transactions contained in the shard inside. So, instead of transactions being verified by the whole network, a boundless number of shards can be created to process transactions on a smaller scale. This translates into the possibility of the network to scale without a limit.

Whose Idea Was It?

Starting from the idea of expansion, one of the co-founders of Ethereum, Vitalik Buterin, wrote an essay elaborating on the concept of Sharding at the beginning of 2018. They’re still working on more improvements. Vitalik proposed even more upgrades for Ethereum in an ambitious three to five years after it merged with PoS.

When Will All of This Come Into Action?

Since it’s been set for scalability in the long term, the most promising strategy of Ethereum must count as a separate upgrade. It must be separate from the rest due to them not wanting to do all the things that could be potentially dangerous at once. First, the merge to proof-of-stake and then the rest, so the people in charge can pay special attention to it and focus.

About the Future

Just as the internet evolved, the network’s evolutión was the result of many crucial steps. Sharding is a significant one in the growth and improvement of Ethereum. If it turns out to be triumphant, it could potentially make the process of thousands of transactions more accessible. This would help the developers of decentralized apps would have a better platform to run their projects.
