Explaining Sharding for Blockchain Scalability
When programmers build decentralized apps (DApp), they are bound by the limits of public blockchains. Their biggest limitation is having limited throughput — the maximum rate at which the blockchain can confirm transactions . To be able to manage a DApp that can take care of real throughput requirements, blockchains need to be scalable.
Sharding is a workable answer to blockchain scaling. It has the potential to increase the throughput and change the way networks validate blocks — all the finished transactions that are permanently recorded in the blockchain. Horizontal scaling is the most vital feature of sharding among all on-chain scaling solutions.
What Is Scalability?
Scalability is a system characteristic which describes how well the system copes and performs with an increasing workload. Any system that scales well can sustain its high performance rate or raise its efficacy despite an increase in operational demands.
To understand scalability better, take the example of a bank. In a well-managed bank, the customers can walk in, go to a clerk, have their transactions quickly taken care of, and leave without waiting or queuing. But, at the beginning and end of the month when customers overcrowd the bank, how will they serve the customers quickly?
Often times, no matter how fast the clerk is, they will not be able to keep up. Likewise, the other bank staff will also be overloaded with work. Situations like these are perfect examples of an institution’s inability to adjust and satisfy customers when demand increases.
Like the example of a bank, scalability issues are also one of the most significant challenges the Bitcoin blockchain industry faces today. Therefore, any discussion about the future of blockchain needs to address these technology scalability issues.
