Introduced in 2017, Zilliqa (ZIL) is a high throughput blockchain network built upon the idea of enhancing scalability for blockchain networks, like Ethereum.
ZIL seeks to achieve this through 'Sharding', where transactions are divided into smaller groups for miners to verify on the blockchain. According to the ZIL white paper, this would allow the network to reach quicker consensus; The number of transactions - in any given period of time - would increase by as much as 1000x that of the Ethereum network.
