After pursuing the expansion of the development of Ethereum, ZK-rollups became the focus of attention


The scalability of Ethereum (Ethereum) The network has been a point of contention in the cryptocurrency ecosystem for many years, mainly due to high fees and network congestion during peak demand periods.

The latest solution that emerged as the final solution to the scalability problem of Ethereum is zero-knowledge rollups (ZK rollups), which is an extended form of running calculations off-chain and submitting them on-chain through proof of validity.

Earlier this year, protocols that chose to use optimistic aggregation (such as Optimism and Arbitrum) dominated the headlines and were touted as the best solution for Ethereum expansion, but with the exception of Arbitrum, the hype for these protocols has subsided, traders pointed out When the network is in peak demand, even optimistic aggregation can incur higher-than-ideal costs.

Early success in 2021

While optimistic rollup solutions have become the focus, protocols using the ZK rollups model have quietly demonstrated their capabilities.

dYdX is a decentralized perpetual contract and futures exchange. Through its cooperation with StarkWare, it has become one of the earliest adopters of ZK-rollup technology. StarkWare’s StarkNet network is a license-free decentralized ZK-Rollup.

So far, the platform has achieved considerable success and sometimes manages to deal with Higher 24-hour trading volume Than Coinbase.

Loopring (LRC) is another protocol that uses ZK-rollup to reduce transaction costs and speed up its throughput. This helped push the price of LRC to a record high of $3.83 in early November.

ZK-rollups may be the next “rotation” for traders

Following the sharp sell-off within the market last week, ZK-rollups has re-emerged as a buzzword in the cryptocurrency field.

Polygon is the second-tier platform of the Ethereum network. Following the announcement of the acquisition of Mir which made headlines, the project developed two zero-knowledge proof subcategories, namely PLONK and Halo.

The 250 million MATIC tokens invested by Polygon have provided the lowest fees of any protocol on the Ethereum network. strive to accomplish “Explore and encourage all meaningful extension methods and techniques at this stage,” said Polygon co-founder Sandeep Nailwal.

Another highly anticipated agreement recently is zkSync, an extended solution created by Matter Labs that received $50 million in a Series B financing led by Andreessen Horowitz in early November.

zkSync total deposits and total number of unique users

According to Digital Delphi, the two main projects on zkSync are ZigZag, a decentralized exchange and a financing platform called Gitcoin.

According to Delphi Digital analysts,

“according to L2 fee, The token exchange fee through ZigZag on zkSync is the lowest. “
