Zilliqa

Zilliqa is a high-performance blockchain designed to handle large numbers of transactions quickly and efficiently through a process called sharding. It was one of the first blockchains to use this technique, which splits the network into smaller parts to process transactions in parallel. This helps Zilliqa scale without compromising speed or security. 
Zilliqa supports smart contracts and decentralised applications (dApps), like Ethereum, but aims to solve the issue of network congestion. Its native token, ZIL, is used for transactions and smart contract execution. Developers often choose Zilliqa for projects that require low fees, speed, and reliable throughput.
