How Polygon zkEVM is becoming a game changer for decentralized applications?

Zeeve - Nov 20 '23 - - Dev Community

Polygon’s leading solution to scalability trilemma– Polygon ZkEVM is a great Layer-2 solution that many enterprises and web3 projects have been utilizing to power their power dApps with unique Zk technology. Polygon zkEVM is becoming highly popular and is getting huge traction with a whopping 6.23M total transactions, 450K unique addresses, and TVL of $52.07M as of now. Web3 projects deploying their Polygon zkEVM dApp can leverage a range of benefits such as EVM equivalence, industry-leading security, and increased throughput. However, there are a lot more things that make Polygon zkEVM a game-changer solution for today’s decentralized applications. 

Through this article, we will dive deeper into Polygon zkEVM and its unique offering for decentralized applications, further understanding Polygon zkEVM’s significance in the web3 space.

Demystifying Polygon zkEVM and its working 

Polygon ZkEVM is Polygon Network’s leading ZK-based Layer-2 scaling solution, enabling web3 projects to build high-performance, secure, and scalable Rollups for Polygon zkEVM dApps. Polygon zkEVM includes Zk + EVM, where ZK refers to Zk-rollups that batch all the transactions from the Layer-1 chain and calculate them off-chain on a Layer-2 Rollup chain. Speaking about EVM– it’s a virtual machine designed to allow recreation of all the existing EVM opcodes for seamless migration and deployment of all the Ethereum smart contracts on the Polygon zkEVM infrastructure. Furthermore, Zk-proof allows Polygon ZkEVM to prove the validity of the transaction using its publicly verifiable zero-knowledge proofs. 

To achieve all these next-level Rollup capabilities, Polygon zkEVM includes three main components– The trusted sequencer, the trusted aggregator, and the consensus contract. Let’s learn more about them:

  • Trusted sequencer: It takes transactions from layer-2, rolls them into batches, and then executes and broadcasts the batched transactions to Layer-2 network nodes. Batch data is transferred to Ethereum by the sequencer.

  • Trusted Aggregrator: It generates zk-proofs for all the batches of transactions and then gets the proofs verified from the smart contract deployed on Layer-1.  

  • Consensus contract: It refers to the Polygon ZkEVM.sol contract that runs on Layer-1 and is responsible for storing batched data from the sequencer, thereby verifying the proof submitted by the aggregator. 
  • Other components that uphold the Polygon zkEVM include zkProver, zkEVM bridge, Zk Nodes, and RPCs, which we will discuss later in this article. To further understand the working mechanism of Polygon zkEVM, refer to the below image:

    What benefits does Polygon zkEVM brings to the decentralized applications?

    Polygon zKEVM is the ‘ideal solution’ for a variety of dApps spanning DeFi, GameFi, NFT marketplace, Payments, and enterprise applications. But, how? To answer this questions, let’s learn about the main benefits of Polygon zkEVM that encourages dApps to build on its ecosystem:

    100% Ethereum Equivalence, not just compatibility

    Polygon zkEVM’s ultimate goal has always been ‘Ethereum Equivalence’, not just compatibility, which this Rollup infrastructure achieves by implementing Type-2 zkEVM. With equivalence, Polygon zkEVM allows dApps to port their existing infrastructure immediately to Polygon zkEVM with fewer changes to the opcodes. All the existing frameworks, Dev tools, wallets, and smart contracts will continue to work seamlessly in a zkEVM environment. 

    This approach saves significant time for web3 projects that might need to invest in the traditional process of migration. The Ethereum equivalence is one of the reasons why Polygon zkEVM is able to leverage the security of Ethereum. Plus, projects building on Polygon zkEVM does not have to be hardcore familiarity with a new language except for Solidity or in some case Vyper. 

    DApps can leverage Massive scalability

    Different decentralized applications built on the Polygon zkEVM ecosystem can achieve massive scalability to accommodate the growing user base. Note that Polygon zkEVM, at its upper range, can offer up to 40,000 transactions per second, which is truly an unbounded scalability offering for all kinds of dApp projects.

    Cost-efficient and rapid proof generation with ‘zkEVM Prover’

    Polygon zkEVM tackles one of the biggest challenges that ZK-based Rollups have been facing for long, which is extremely high cost in a zero-knowledge proof generation. Polygon zkEVM adopts a special kind of zkProver that uses ‘state machine approach’ (instead of an arithmetic circuit model) for batching a batch of many transactions, providing their validity, and simultaneously generating a minimally-sized validity proof.  

    This zkEVM prover is powered by three methods– Stark recursion, aggregation, and composition, which allows Polygon zkEVM to produce zero-knowledge proof for a batch of transactions within 4 to 10 minutes– reducing the time significantly while improving the scalability capabilities of the Polygon zkEVM infrastructure

    Extremely low gas fee 

    Polygon zkEVM allows dApps to keep the gas fee as low as 0.000086 ETH. To achieve this, Polygon Zk-rollup leverages the power of ZK Proof and combines it with Polygon zkEVM’s extremely fast prover that keeps the cost between layer-1 gas schedule and actual Polygon zkEVM’s resource consumption marginal.

    Greater Security and privacy 

    Polygon keeps a greater focus on security. Therefore, Polygon zkEVM inherits security from the underlying Layer-1, and meanwhile, it implements Polygon’s native security features, such as ‘Validium’ and ‘censorship resistance’ for Polygon zkEVM dApps. This enables web3 projects to build decentralized applications enriched with industry-leading security. Furthermore, Polygon zkEVM also maintains complete privacy as it processes the transactions off-chain- only the validity proofs are submitted on Layer-1 for public verification, with no disclosure about transactions and transaction data. 

    No need for a separate token

    Polygon zEVM wants to keep the dApp experience as simple as possible. Therefore, users do not need a separate token to interact with the Polygon zEVM ecosystem. For the purpose of staking and governance, Polygon’s native token– MATIC is used. Further, Polygon zkEVM supports ‘Account Abstraction’ via ERC-4337 which allows your network to accept transaction fees in any token.

    Interoperability with native zkEVM bridge 

    Knowing that interoperability is critical for improving the feasibility of decentralized applications, especially for DeFi and GameFi dApps– Polygon Team has created their native Polygon zkEVM Layer-2 bridge that enables communication and asset transfer between Polygon zkEVM network and other networks, including Layer-1 blockchain and the Layer-2 networks built on the top of Ethereum. With the Polygon zkEVM bridge, you do not need to change the original asset’s value or its functionality in order to transfer it from one network to another. In a nutshell, this bridge retains user experience and meanwhile unlocks the interoperability benefit on the Polygon zkEVM ecosystem. 

    DApps leveraging Polygon zkEVM ecosystem

    Having witnessed the tremendous success of Polygon zkEVM and realizing its next-level benefits, a variety of dApps are being built on the Polygon zkEVM ecosystem. QuickSwap, ScalarDAO, Ovix, Kredeum NFTs Factory, Obvious, DAuth Network, Owlto Finance, LI.FI exchange, Mobula API, DRPC, and Add3 are some of the feasible Polygon zkEVM dApps that are leveraging its ZK technology. Almost every day, a new announcement is being made on Polygon about dApps migrating to Polygon zkEVM ecosystem or launching their own Zk-rollup with Polygon CDK. This signifies the fast growing importance of Polygon and its technology for web3 enterprises and dApp projects.
