**\*\***[**zkSync**](https://zksync.io/)**\*\*Introduction**

[zkSync](https://zksync.io/) is a scaling and privacy focused engine for Ethereum. Its current scope of features includes low gas transfer of ETH and ERC20 tokens on the Ethereum network, atomic swaps and limit orders, and built-in support for L2 NFT.

ZkSync is built on ZK-Rollup technology, but I always had a hard time understanding what it is, so I'll try to explain it in simple words.

ZK-Rollup is a smart contract that takes hundreds of transactions out of the main blockchain and combines them into one transaction, and then it sends validation back to the main blockchain.

Validity proofs ensure state correctness: Each update to the system state must be accompanied by a ZK Proof that ensures that the new state was derived by correctly applying a series of valid user transactions to the previous state. Once the proof is processed on the Ethereum blockchain the L2 block is instantly finalized.

Zero knowledge SNARK cryptography is used: Despite their production use ZK-SNARKs are still new and experimental cryptography. Cryptography has made a lot of advancements in the recent years but all cryptographic solutions rely on time to prove their security. In addition ZK-SNARKs require a trusted setup to operate.

You can read more about the technology in [their documentation](https://docs.zksync.io/userdocs/security/#validity-proofs).

**Fundraising:**

*   [Series A](https://blog.matter-labs.io/funding-ea89c1fa731e) \- $58 Million from Andreessen Horowitz, Blockchain.com, Crypto.com, Consensys, ByBit, OKEx, Alchemy, Covalent, and More;
    
*   Separate ecosystem fund of $200 million
    
*   [Series C](https://blog.matter-labs.io/announcing-200-million-in-new-funding-to-accelerate-the-zksync-mission-a9d59c1583c8) - $200 Million round led by Blockchain Capital and Dragonfly Capital, with participation from Lightspeed, Variant, and a16z.
    

Our latest Series C round brings the total funding for the zkSync mission to $458 million.

The aggregate of these fee amounts makes it possible to count on significant rewards for early supporters of their network. The network has been running for over a year, not that snapshots haven't already been made. But we will still try to be active there and try to get our piece of this drop, which could be very significant.

Below we will tell you about the current activities that are currently on the network:
