As layer-1 protocols move closer to implementing zero-knowledge rollup solutions at scale, the discussion and enthusiasm around this technology are growing. Zero-knowledge rollup has the potential to resolve one of Web3’s most challenging issues: constrained cost and scalability limits. High transaction fees, congestion, and other factors have created a blockage in Ethereum’s ability to support an increasing number of users. The adoption of a zero-knowledge rollup could help address these challenges effectively. Rollups and layer 2 solutions have been created to help with scalability issues, but none of them has been tested at the level needed for mass adoption.

Although these technologies can offer many advantages, they also bring new obstacles concerning how data is managed while still maintaining decentralization and censorship resistance. To ensure the mass adoption of Web3 technology, we must prioritize decentralization and security above all else before attempting to implement rollups.
What is Rollups?
Rollups are becoming increasingly popular layer-2 scaling solutions as they allow hundreds of thousands of small transactions to be quickly bundled into one single transaction for submission on the base (e.g., Syscoin) layer at a fraction of the cost. This off chain processing results in faster settlement times, and helps unlock mainstream capacity through eased pressure on the underlying blockchain network.
What is ZK Rollups?
Zero-knowledge (ZK) rollups are a cutting-edge layer-2 scaling solution that takes computations off the parent blockchain. Composed of numerous transactions, ZK rollups form a “rollup” of data which is then securely submitted to the main network. A key advantage over its optimistic rollup counterpart is faster settlement time on both layers – enabling near-instant transaction finality on either side of the chain. ZK-rollups harness their zero-proof technology to send regular validity proofs to corresponding smart contracts on the parent network, confirming the accuracy of transactions on the layer-2 network. This effectively reduces the volume of shared transaction data while making ZK rollups more privacy-oriented by default.
Average wait times are eliminated with this solution; users may withdraw from a layer 2 system almost immediately after initiating transfers. However, as it is still in an early stage of development, that also means this technology has its drawbacks as well. Building ZK rollups can be complex and may involve sophisticated setup processes, such as setting up expensive hardware to validate transactions. Furthermore, depending on the approach taken by developers of a specific platform, these solutions can potentially introduce censorship vulnerabilities due to centralized transaction sequencing models. Potential users need to assess each platform’s solution independently to examine any centralization factors involved with that particular implementation.
What are the different ZK Rollup projects?
ZK rollups are rapidly gaining traction in the crypto industry due to their numerous advantages over traditional solutions. They provide decentralized applications with scalability and cost-efficiency, while also offering compatibility across multiple blockchains. As this cutting-edge technology continues to advance, we can expect more use cases from a wider range of industries. zkSync is a popular scaling solution that utilizes ZK rollups, enabling token transfers and payments with strong privacy. Recently, the solution upgraded to zkSync 2.0 which will allow developers to deploy decentralized applications (dapps) on the network.
StarkNet is a ZK Rollup project, enabling Ethereum-based applications to increase their throughput while maintaining low costs and fast transaction settlement. dYdX and ImmutableX are two leading decentralized protocols utilizing StarkNet’s solution to facilitate faster transactions with reduced fees. Ethereum has long faced scalability issues, but now advanced networks such as Syscoin are harnessing the power of ZK rollups (and Optimistic) to store data off-chain and allow for full scalability without compromising on decentralization. This creates a mainstream-ready solution that allows dApp developers greater scaling capability than ever before.
