Polygon Network’s (MATIC) zkEVM: Everything You Should Know in New Blockchain Guide

On July 20, 2022, Polygon Community (MATIC), an ecosystem of Ethereum (ETH) scaling options, unveiled zkEVM, the newest addition to its stack of options. The brand new product is the primary open-source zk-rollup natively interoperable with EVM.

On this information, we are going to cowl the options of the brand new launch and the alternatives it opens for Ethereum (ETH) scaling and Web3 progress as an entire.

Polygon Community releases zkEVM: Why is this significant for crypto?

zkEVM (an abbreviation for “zero-knowledge Ethereum Digital Machine”) is a second-layer scalability protocol on the highest of Ethereum (ETH). Which means it’s designed to make the operations of Ethereum (ETH) dApps sooner and cheaper with out compromising its decentralization and safety.


Even if second-layer options have been serving to Ethereum (ETH) scale since 2018, zkEVM launches to vary the narrative in L2s.

  • zkEVM helps Ethereum (ETH) good contracts with out adjustments, there isn’t any want to switch the code earlier than shifting from L1 to L2;
  • zkEVM onboards all Ethereum (ETH) opcodes; each instrument from the “authentic” Ethereum (ETH) can due to this fact be carried out in zkEVM;
  • Utilizing on-chain knowledge permits customers to save lots of as much as 90% in charges;
  • zkEVM has been open supply and MIT-licensed since day one: each Web3 group can experiment with zkEVM and audit it;
  • Superior zero-knowledge strategies: recursive STARKS assure excessive scalability whereas zkSNARKS are built-in for price optimization.

With zkEVM launched, Polygon Community (MATIC) strengthened itself as the most efficient and cutting-edge group in Ethereum’s L2s ecosystem.

What are Layer 2 options (L2s) — and why does Ethereum (ETH) want them?

Layer 2 options (additionally second-layer options, or L2s) are blockchain protocols constructed on the highest of the Ethereum (ETH) mainnet. As Ethereum (ETH) itself has a low bandwidth — it could solely course of 15 transactions per second — it turns into too sluggish and inefficient for contemporary decentralized functions.

As such, builders determined to create techniques designed to scale back “transactional stress” on the Ethereum (ETH) mainnet. Merely put, they partially course of the computations off-chain after which broadcast the outcomes to Ethereum. Layer 1 Ethereum (ETH), in flip, verifies these outcomes and contains them into new blocks.

Because the inception of the primary Ethereum (ETH) L2 answer, Rayden Community (RDN), which used fee channels not not like Bitcoin’s Lightning, plenty of groups launched their very own model of scaling designs. By 2022, rollups proved to be probably the most spectacular method when it comes to useful resource effectivity, velocity and lowered transaction prices.

What are zk-rollups and zk-proofs?

Zero-knowledge rollups, or zk-rollups, ought to be thought of a category of second-layer options designed to advance the throughput of the Ethereum (ETH) mainnet. Zk-rollups bundle (roll up) a number of Ethereum (ETH) transactions into batches earlier than posting solely minimal knowledge to the Ethereum (ETH) mainnet.


Technically, a zk-rollup chain is an off-chain protocol that operates exterior of Ethereum’s (ETH) mainnet however leverages on-chain Ethereum (ETH) good contracts. This good contract deconstructs and verifies the entire transfers “bundled” in a single L2 transaction.

Zk-proof is one other essential idea of L2 structure. On this case, “zero-knowledge” signifies that these cryptographic proofs enable each events (L1 and L2) to show the correctness of a “assertion” with out revealing the assertion itself. Zk-rollups use proofs to confirm the correctness of off-chain state transitions with out the need of re-executing transactions on Ethereum (ETH) mainnet.

What’s Polygon Community (MATIC)?

Polygon Community (MATIC) was launched as Matic Community in October 2017. The challenge is helmed by Ethereum (ETH) veterans Jaynti Kanani, Sandeep Nailwal, Anurag Arjun and Mihailo Bjelic. Initially, it was launched as a Plasma-based L2 on high of the Ethereum (ETH) community. Plasma is a category of proof-of-stake options for Ethereum (ETH) scaling; not not like rollups, its mechanisms periodically ship parts of transactions to Ethereum (ETH) in a compressed type.

In 2019, Polygon (then, Matic Community) raised $5.6 mln in its ICO. One 12 months later, the challenge determined emigrate from Ethereum (ETH) to its personal blockchain — technically, Ethereum (ETH) sidechain. In 2021, the challenge rebranded to Polygon Community and launched a full-scale ecosystem of L2 options for Ethereum.

At the moment, its stack contains Polygon Proof-of-Stake, a blockchain that handles MATIC transactions and onboards Polygon-based dApps, and Polygon Supernets, purpose-made sub-blockchains. Additionally, Polygon Dusk privacy-focused rollup is in mainnet beta. Final however not least, its ecosystem of rollups — Avail, Zero, Miden and, most just lately, zkEVM — is beneath improvement.

zkEVM by Polygon Community: Ethereum (ETH) scaling, reconsidered

zkEVM is a brand new rollup design developed by Polygon Community (MATIC) engineers. It’s poised to radically streamline the builders’ expertise for dApps centered on utilizing Ethereum’s L2s as a technical foundation.


Launched on July 20, 2022, zkEVM is the newest addition to Polygon Community’s (MATIC) L2 scalability stack. zkEVM promotes itself as a first-ever EVM-compatible ZK-based rollup. The challenge is 360° open supply: since its very first days, each Ethereum (ETH) fanatic can use, audit and fork its codebase.

Polygon Community’s zkEVM is concentrated on attaining Ethereum-level safety and decentralization, drastically boosting throughput, efficiency and useful resource effectivity.  zkEVM leverages Plonky2, a cutting-edge zk-based scaling know-how. Plonky2 makes very gentle proofs and facilitates recursive verification of SNARKS (“Succinct Non-Interactive Argument of Data”). This enables customers to verificate proofs at 100x lowered velocity.


Apart from improved proof-generation occasions, zkEVM creates alternatives for unbelievably low cost transactions; each dApp on zkEVM is way extra cost-efficient than its Ethereum-based opponents.

Seamless migration from Ethereum (ETH)

However probably the most spectacular “secret sauce” of the brand new product is its 100% compatibility with Ethereum (ETH). Builders can actually make the most of the identical devices they used whereas constructing on-chain functions for Ethereum (ETH) mainnet.

Builders can run Ethereum’s good contract on zkEVM with out altering a single line of code. All Ethereum (ETH) instruments might be seamlessly built-in into zkEVM-based dApps: the brand new product  will help all Ethereum (ETH) opcodes. Thus, Ethereum’s (ETH) battle-tested safety might be inherited by a new product:

EVM-equivalence signifies that any good contract or dev device that you need to use on Ethereum can be utilized on Polygon #zkEVM. It’s identical to utilizing Ethereum, however with the groundbreaking scaling energy of ZK tech.

Unmatched useful resource effectivity

Apart from EVM equivalence, zkEVM leverages enforced censorship resistance structure and advocates a decentralized-by-default design. Polygon zkEVM employs an extendable EVM processor with a brand new zk-assembly language to remain on the slicing fringe of Web3 innovation.

Technically, Polygon zkEVM is powered by Polygon Zero’s (beforehand Mir Protocol) quickest zk-proof design in Web3. zkEVM’s zkSNARK makes use of the minimal doable assets of Ethereum’s L1 for extra environment friendly computations.


After the official announcement of Polygon zkEVM’s launch in July 2022 and making its code-base open supply, Polygon Community (MATIC) engineers are heads down, getting ready for his or her public testnet launch.

As such, a public testnet might be reside as quickly as Q3, 2022. The mainnet launch of the game-changing protocol is tentatively scheduled for early 2023.

Backside line

Polygon Community, a number one ecosystem of Ethereum L2 scaling devices, unveiled its zkEVM rollup. Polygon zkEVM is about to be “EVM-equivalent” because it helps all Ethereum (ETH) good contracts and improvement devices.

Apart from EVM equivalence, Polygon zkEVM melds super-low charges and near-zero latency with the battle-tested safety of the Ethereum (ETH) mainnet.
