Scalability on the Ethereum (ETH) network has been a point of contention within the cryptocurrency ecosystem for years, primarily due to high fees and network congestion during periods of acme demand.

The latest solution to emerge equally the concluding ready to Ethereum's scalability woes is zero-knowledge rollups (zk-Rollups), a class of scaling that runs computations off-concatenation and submits them on-concatenation via a validity proof.

Earlier in the year, protocols that opted to use optimistic rollups such as Optimism and Arbitrum dominated the headlines and were touted every bit the best solution to scaling on Ethereum, but bated from Arbitrum, the hype for those protocols has quieted down and traders accept pointed out that even optimistic rollups have higher than desirable fees when the network is under peak demand.

Early successes in 2022

At the aforementioned time that optimistic rollup solutions were in the spotlight, protocols that adopted the zk-Rollups model quietly demonstrated their capabilities.

dYdX, a decentralized perpetual and futures exchange, was ane of the earliest adopters of zk-Rollup technology through its partnership with StarkWare, whose StarkNet Network is a permissionless decentralized zk-Rollup.

To date, the platform has seen a decent amount of success and at times, has managed to procedure a college 24-hour trading volume than Coinbase.

Loopring (LRC) is another protocol that has utilized zk-Rollups to decrease transaction costs and speed up its throughput capabilities, which has helped drive the price of LRC to a new best high of $3.83 in early on November.

zk-Rollups could be the next "rotation" for traders

Following last calendar week's sharp market-wide sell-off, zk-Rollups have reemerged as a buzzword in crypto sector.

Polygon, a layer-two platform for the Ethereum network, made headlines with the announced conquering of Mir, a project developing two subcategories of zero-cognition proofs known as PLONK and Halo.

The 250 one thousand thousand MATIC token investment by Polygon, which already offers some of the lowest fees of any protocol on the Ethereum network, was washed in an attempt "to explore and encourage all meaningful scaling approaches and technologies at this phase," according to Polygon co-founder Sandeep Nailwal.

Another much-anticipated protocol that has been gaining traction recently is zkSync, a scaling solution created past Matter Labs that secured $50 million in a Series B round led by Andreessen Horowitz in early November.

Co-ordinate to Digital Delphi, the two main projects that are live on zkSync is ZigZag, a decentralized exchange, and a funding platform called Gitcoin.

Analysts at Delphi Digital said,

"According to L2 fees, token swaps through ZigZag on zkSync accept the lowest fees."
