Israel-based StarkWare announced on Tuesday by way of Twitter that it had raised $50 million in a Collection C funding spherical, and that the agency’s valuation is now at $2 billion. Sequoia Capital was the lead investor, amongst different contributors. Seven months in the past, StarkWare raised $75 million in a Series B funding led by Paradigm.

This information comes forward of the launch of StarkNet Alpha 2, an improve to its Zero-Information Rollup know-how, or zk-Rollup, on Ethereum mainnet, which is at the moment scheduled for deployment by the top of November. The corporate mentioned that StarkNet Alpha plans to assist permissioned sensible contract deployment, opening up the scaling know-how to whoever needs to construct on it.

StarkWare is among the many few layer-two scaling protocols for Ethereum which have just lately surged in adoption regardless of the climb in fuel costs. Its StarkEx L2 scalability engine has allowed companions, corresponding to buying and selling platform dYdX, to submit on-chain trades in zk-Rollups. This minimizes buying and selling charges by decreasing the quantity of fuel. The dYdX change just lately launched a governance token, DYDX, and its airdrop surpassed $100,000 for probably the most lively customers.

There are two important kinds of rollup know-how: zk and Optimistic Rollups. Whereas Optimistic Rollups assume transactions are legitimate by default and solely run the computation, ZK-Rollups generate zero-knowledge proofs for validating transactions and submit these proofs to the Ethereum mainnet constantly. With a zk-Rollup, validating a block and transferring funds is faster and cheaper as a result of much less information is included.

Starkware’s L2 competitor Polygon concurrently launched its zk-STARK powered Miden Virtual Machine for the event of decentralized functions, also referred to as DApps.
