The crypto environment is expanding, and as a result, blockchains are experiencing scalability problems as crypto adoption grows. Bitcoin, for example, is actually the largest crypto business capitalist, with over 299 thousand transactions every day. Bitcoin's network has daily outages as a result of its massive growth.

However, bitcoin isn't the only cryptocurrency with scalability issues; Ethereum, the second-largest crypto business capitalist, still has problems. As a result, the scalability problem threatens the entire crypto ecosystem and necessitates immediate solutions.

A new algorithm known as sharding may be the solution to scalability issues that are becoming more prevalent. However, what exactly is sharding and how does it work?

Sharding

Sharding, also known as horizontal partitioning, optimises a database by dividing it into smaller, operationally separate chunks known as shards. The database's operation can be spread through several servers, including machines, thanks to the shard's independence, resulting in increased storage and operating power. Horizontal partitioning differs from vertical partitioning in that it gives the machines more processing resources, including more RAM and improved CPU functionality.

The basic concept behind database sharding is to distribute a dataset that can be accessed from a single node to multiple nodes. When added to the blockchain, sharding improves its functionality and eliminates the threat of year-round scalability.

Consider the Bitcoin blockchain, which processes approximately five transactions a second at the moment. Rather than concentrating on increasing computing resources, developers can opt to split computations into different shards to increase Bitcoin's transaction processing pace. The Bitcoin developers would then connect more operating machines to the database to support it. Any blockchain that uses sharding can greatly increase the amount of transactions per second.

Since shards are self-contained, their continued cooperation improves the blockchain's functionality. Developers should make sure the database is up to date with the latest transactions.

Sharding Techniques

  • Key sharding

The newly published hash value is used to decide the shard to position data in with key sharding, also known as hash sharding. When a numbered input is passed through a hash function, a hash value is released. The data is distributed to bits using key sharding, which avoids cases where relative values are stored in the same fragment. This completely eliminates hotspots, balancing the blockchain's transaction processing.

  • Ranged Based Sharding

The most simple sharding algorithm to implement is range-based sharding. It simply entails splitting data or objects into value ranges, such as price ranges, weight ranges, and so on. However, sharding does not protect data from being distributed unevenly. As a result, the database will eventually develop hotspots that slow down database general operations.

  • Geo Based Sharding

The breakdown of data based on geological positions is the first step in geo sharding. Following this, the database creates shards using one of the two sharding techniques mentioned above.

The Pros

Sharding has a plethora of advantages, the most important of which is the ability to add more computers. Since work is uniformly distributed, adding computers means that there are no computer overloads.

In the blockchain, more computers means quicker transaction completion. As a result, if Bitcoin were to combine sharding techniques in the blockchain, the number of transactions per second will skyrocket.

Since there are no blockchain downtimes, shard independence also comes with the advantage of absolute blockchain dependability. On blockchains, non-sharded databases suffer outages, resulting in the platform's complete inaccessibility. In sharded databases, however, if one shard goes down, the others continue to run.

The overall protection of the sharded platform is another key advantage of the sharding technique. Hackers will never have complete access to the database; instead, they will monitor a single shard while the rest of the database continues to function normally.

The Cons

While this method is promising for blockchains, it has a number of drawbacks. The first is that users may lose essential data because device backups from earlier non-sharded databases are incompatible with sharded databases.

Furthermore, sharding could result in an imbalance of blockchain service provision, depending on the attributes or techniques used. Some database shards with less users, for example, can run faster than hotspots with more users, resulting in partial database unreliability.

Another factor impeding acceptance is the difficulty of applying sharding techniques. Additionally, sharding can lead to security issues such as a shard takeover, which occurs when one shard attacks another.

Conclusion

Although many blockchains, particularly large ones, have scalability issues, incorporating sharding into their databases may help to alleviate the problem. The method divides data into tiny, independent partitions that can be accessed by other computers. Sharding may take several forms, including main, range, and geo sharding, all of which benefit operational efficiency by increasing resources.

Furthermore, through reducing the likelihood of downtimes, sharding guarantees the blockchain's maximum pace and full durability. Sharding, on the other hand, has its own set of problems, such as difficulty and service imbalance.

Several blockchains, like Ethereum, have yet to officially implement the technique in their networks. The benefits vs. the drawbacks of sharding in blockchains is a matter of benefits vs. drawbacks.
