The first and foremost difference between optimistic rollups and zk-rollups is evident in how zk rollups work and offer value advantages. Let us reflect on the various highlights in the difference between optimistic rollups and zk-rollups. First of all, it is important to note that ZK-rollups create a cryptographic proof with each bundle of transactions featuring a validity proof. On the other hand, optimistic rollups assume that all transactions are valid unless disputed. Therefore, the optimistic rollups submit transaction bundles without any verification.
The optimistic rollups can offer better scalability due to limited need for computation. On the other hand, the challenge period or dispute period is a formidable setback with optimistic rollups. The dispute period generally translates into extended withdrawal periods. However, optimistic rollups have some plausible advantages over zk rollups, such as the support for smart contracts. On top of it, optimistic rollups are cost-effective in comparison to zk-rollups which require higher off-chain costs for creating validity proofs. Ultimately, zero knowledge rollup comes at the top for supporting users with better speed than optimistic rollups.
Zero-Knowledge Rollups – Simply Explained
The problems with new technologies like blockchain take some time to shape up. You need to learn about the best practices for resolving the problems so that you can make most of blockchain. What type of problems do you have with existing blockchain networks? The answer points to scalability, and zero-knowledge rollups offer a flexible solution for scalability issues.
People experience various difficulties in terms of scalability on blockchain networks. How? The rising popularity of Ethereum as a trusted blockchain network for developing decentralized apps is one of the biggest reasons for pursuing scalability issues. Will ZK rollups solve the problem? The following discussion helps you find out more details about zk-rollups and how they work.
Working of Zero-Knowledge Rollups
If you want to learn how zk rollups work, you must prepare with an in-depth understanding of the underlying concept of zero-knowledge proofs or ZKPs. Zero knowledge proofs basically offer a cryptographic mechanism wherein you can prove that you have specific information without actually revealing the information. For example, you can prove that you know the password to a Facebook account by sending a screenshot of the Facebook feed of the concerned account without revealing the password. Interestingly, ZKPs is one of the most dominant forces in the evolution of the blockchain landscape.
ZK Rollups leverage ZKPs by bundling up a wide range of layer 2 transactions into one transaction. The one transaction is published on the Ethereum mainnet for mining purposes. Rather than mining for hundreds of individual transactions, ZK-rollups can help in rolling them up into one transaction. Now, the single transaction would qualify as a validity proof, also referred to as a zk-SNARK or Succinct Non-Interactive Argument of Knowledge or a zk-STARK, also known as Succinct Transparent Argument of Knowledge.
The role of SNARKs and STARKs in any zk rollup projects would be almost the same as cryptographic transaction hashes. You can find multiple components in a general Ethereum transaction. However, it is possible to represent all of them in a unique transaction hash without revealing any transaction data. Finally, mining the one transaction with zk rollups rather than the hundred transactions makes them considerably cheaper in comparison to the layer 1 chain.
At the same time, zk-rollups also provide the assurance of better time savings in comparison to optimistic rollups. ZK-rollups don’t wait for the time to obtain fraud proofs. On the contrary, they use a zk-SNARK so that the receiving smart contract could verify validity of the proof on-chain. The instant verification of zk-SNARKS ensures faster withdrawal of funds on zk-rollups immediately after mining the zk-SNARK transaction on Ethereum.
Examples of Zero-Knowledge Rollups
The introduction of zero-knowledge rollups is incomplete without a point at the top examples of the same. If you want to know more about the functioning of zk-rollup platforms, you must learn about the top players in the sector. Some of the notable examples of zk rollup projects you should look up right now include the following mentions.
ZKSYNC
zkSync is one of the popular entries among Ethereum layer 2 scaling solutions developed on the foundations of zk-rollup technology. The zk-rollup solution provides important value advantages such as lower costs and faster transactions. As the best zk rollup example, it helps in off-chain transaction processing at unbelievable speeds of almost more than 2000 transactions per second.
The other important highlights of zkSync pointed out how it does not compromise security. Most important of all, you can get all these advantages with extremely low gas costs. The security advantages of the main Ethereum blockchain enable easier and frictionless crypto transfer among layer 1 and layer 2 without any latency.
LOOPRING
The next name among discussions on zk rollups crypto would draw the limelight on Loopring or LRC. It provides a layer 2 solution on Ethereum, which can facilitate faster settlement alongside cost-effective transactions. The primary idea underlying the platform focuses on helping users leverage ZKPs for developing their personal non-custodial order book crypto exchange. Loopring uses zero-knowledge rollups to enable exchanges to take care of off-chain transaction validation. As a result, it sends limited transactions to the Ethereum network and opens up the possibilities for faster and more cost-effective trades.
IMMUTABLE X
Another top name in a zk rollup example list would obviously draw Immutable X platform into the equation. It is a layer 2 scaling solution suitable for trading Ethereum gaming non-fungible tokens or NFTs. The Immutable X platform leverages zk-rollup technology to ensure instant trade verification with limited gas fees in NFT trading. On top of it, the platform has the capability to process more than 9000 transactions every second. The most striking highlight of Immutable X is the facility for users to set their custom trading fees. Above everything else, NFTs created and traded on Immutable X are completely carbon neutral without any harm to the environment.
Bottom Line
The final impression regarding zero-knowledge rollups shows that they are an interesting improvement over common scaling solutions. As one of the top Ethereum layer 2 scaling solutions, zk-rollups come with many plausible advantages. First of all, they leverage the functionalities of ZKPs, an interesting innovation in blockchain security.
On top of it, you have many popular examples of zk-rollups serving productive use cases across different blockchain networks. You can find notable value advantages for scalability in modern blockchain networks. At the same time, you should not miss the setbacks in zk-rollups, such as intensity of the valid proofs for computation. You need to dive deeper and learn more about scaling solutions to figure out the best option for you now.
