Zero-knowledge rollups hold significant potential as an ideal scalability solution for Ethereum.
Therefore, to take advantage of this fast-developing technology, here’s a list of protocols that implement ZK-Rollups and their coins.
The Loopring network is a ZK-Rollup-powered project that enables developers to create exchanges or DEXs with fast settlement for traders on the Ethereum network. Loopring DEXs offer low-cost trading and payment on the Ethereum blockchain, leveraging the high-throughput advantage of ZK proofs.
ZK-Rollups enable Loopring DEXs to take settlement computation off-chain, rather than settling directly on the Ethereum blockchain like other exchanges. This slashes the number of transactions submitted to the Ethereum network, easing congestion, increasing speed and reducing trading costs.
LRC is the native utility token of the Loopring network. Traders pay in LRC when processing each trade. On Loopring, 80% of the funds are sent to the liquidity providers, and the balance is shared between insurers and Loopring’s DAO.
The LRC price could be affected by the performance of the Ethereum network. As transactions on Ethereum increase, slowing down the network and driving fees higher, more users will favor scalability solutions such as Loopring.
Immutable X is a Layer 2 scaling solution for non-fungible tokens (NFTs) on Ethereum. It uses ZK-Rollups to scale up instant trading, and to eliminate gas fees for NFT minting and trading, without sacrificing the security of users and assets.
IMX is the native utility token of the Immutable X protocol. Users can earn IMX by trading and carrying out other activities on the network. IMX can be used to pay fees, to stake on the protocol, or as a governance token.
Immutable X stands at the intersection of three popular narratives in the crypto space —
NFTs, ZK-Rollups and Gaming ― making it a promising asset worth considering. Furthermore, because its zero gas fees for trading NFTs attract more developers to the platform, Immutable X is primed for substantial growth.
Polygon network is a ZK-Rollup-based protocol for building and connecting Ethereum-compatible blockchain networks. It allows developers to build DApps which combine the high-security features of Ethereum with the low gas fees and scalability of Polygon Network.
MATIC is the native token powering the Polygon Network. It’s used to pay transaction fees, and can also be staked in the PoS consensus to earn passive income. Users can earn MATIC by providing resources for transaction validation and executing smart contracts on the network.
The main reason to keep an eye on MATIC is the rapid growth of the Polygon network, with more interoperable projects launching on it. Also, Polygon has recently acquired the Ethereum scaling startup Mir Protocol for $400 million. Mir Protocol boasts the fastest and most advanced ZK-proof technology, called Plonky2, which was designed to generate proof faster and to verify more transactions in one proof.
This is the second major acquisition by Polygon, having previously bought ZK-Rollup Hermez Network (now Polygon Hermez) for $250 million.
Syscoin is a PoW blockchain that combines Layer 1 and Layer 2 elements to create a platform for the development of Web 3.0 DApps. It combines the high security of Bitcoin and the DApp capabilities of Ethereum (using a ZK-Rollup scaling solution) to create fast and secure DeFi products. The Syscoin project aims to create a platform for organizations to utilize distributed ledger technology with high security, low cost and high scalability.
