Every blockchain network has its own technology and method for addressing typical issues with blockchain technology, especially given that blockchain networks have already experienced scaling issues. Confirming transactions can be time-consuming and costly at times. The founders of the Ziliqa smart contract platform recognized this as a major issue and provided a solution.
Miners' network congestion may be alleviated, and scalability can be improved, thanks to their approach. Ziliqa proposed a divide-and-conquer strategy, in which jobs are separated into pieces and transactional verification is performed by miners. Sharding is the technical term for this.
