StarkNet is a sort of Ethereum scaling arrangement known as a ZK rollup. ZK-rollups can scale to millions, even billions of individuals. Furthermore, the more individuals use them, the less expensive they become. This without settling on Ethereum's security and decentralization! .
BENEFITS OF STARKNET
Dissimilar to other ZK rollups, as zkSync, StarkNet isn't a "zkEVM" - this implies smart contracts (which power your number one Dapps on Ethereum, as Uniswap and OpenSea) must be written in StarkNet's own programming language - Cairo.
Cairo is a staggeringly strong language upgraded for ZK rollups. It permits you to give your very best on an EVM and substantially more, as calculations are essentially less expensive.
This makes altogether additional opportunities that beforehand were absurd on blockchains, for example, genuine blockchain games!
As Cairo is another programming language, designers that might want to begin coding for StarkNet might be put off from doing as such as they would need to learn Cairo. Fortunately savvy contracts composed for Ethereum can be changed over into Cairo utilizing a "transpiler", like Nethermind's Twist, yet they will not be completely enhanced for StarkNet.
