Zilliqa is the world's first high-throughput public blockchain platform designed to scale to thousands of transactions per second. Zilliqa has been under research and development for two years. It brings the theory of sharding to practice with its novel protocol that increases transaction rates as its network expands.
Zilliqa processes more transactions per second as more mining nodes join the network. This may sound like a natural thing at first, but it turns out to be technically challenging to accomplish, and certainly hasn’t been possible by past blockchain protocols. Getting consensus in a larger crowd is technically harder! Zilliqa’s novel consensus protocol solves this problem. With Zilliqa’s scalability, we can support dApps that demand transaction rates beyond today’s blockchains. Zilliqa only leverages PoW to establish mining identities. This process defends against sybil attacks and is also used to perform network sharding.
Unlike other blockchains though, Zilliqa does not use PoW for consensus. PoW is performed only at larger intervals, not by every miner on every block. Thus, it has a much smaller energy footprint. We’ve stayed with PoW since it has been well studied in the literature and field-tested, while its emerging alternatives (such as PoS) are still under active research.
