Polygon’s ZK-rollup Ethereum scaler Miden hits testnet

The Ethereum layer-2 scaling solutions provider is going up against StarkWare’s tech stack Starknet.

Ethereum layer-2 developer Polygon has launched an alpha version testnet of its latest zero-knowledge rollup (ZK-rollup) solution called Miden as the Ethereum scaling competition heats up.

In a May 6 X post, Polygon said the Polygon Miden Alpha Testnet zero-knowledge was live for developers to begin testing. Miden is a ZK-rollup designed to extend the capabilities of the Ethereum blockchain.

Polygon’s latest solution — like other ZK-rollups — uses a type of cryptography where data can be verified or “proved” without revealing what the data consists of to the rest of the network.

Ethereum scaling firm =nil; Foundation introduces security-focused zkEVM

A new Ethereum zero-knowledge proof compiler could address security concerns identified in different zkEVM solutions.

Zero-knowledge technology firm =nil; Foundation has developed a new type-1 zero-knowledge Ethereum Virtual Machine (zkEVM) compiler to address security concerns identified in similar ZK-powered Ethereum scaling solutions.

Speaking exclusively to Cointelegraph, =nil; Foundation CEO and co-founder Misha Komarov says the technology prioritizes security and allows high-level programming code to be compiled automatically into Zero-Knowledge Succinct Non-Interactive Argument of Knowledge (zk-SNARKS) circuits.

The firm’s zkEVM is designed to be compatible with evmone, which is a C++ version of Ethereum’s base execution environment. The key takeaway is that the code of applications is processed and rolled up as proofs submitted to Ethereum in the same format as its EVM.

ZK-focused Manta Pacific opts out of OP Stack for Polygon CDK

Manta Pacific’s ZK-application-focused network will integrate with the Polygon ecosystem through the Chain Development Kit software.

Manta, a blockchain network focusing on zero-knowledge (ZK) applications, will migrate its software from OP Stack to Polygon CDK, according to an October 16 announcement. This means that Manta will not be integrated into the upcoming Optimism Superchain and will instead become part of the Polygon ecosystem.

Manta network is an Ethereum layer-2 focusing on zero-knowledge-based applications, including digital identity and privacy solutions. It launched a mainnet on September 12 and has processed more than 500,000 transactions.

Manta was originally developed as an optimistic rollup that uses the OP Stack software developed by Optimism Labs. This software is intended to help create a “Superchain” of interconnected networks that will share the same security model. However, it faces competition from the Polygon Chain Development Kit (CDK), which employs a different security model but is also used to create a web of interconnected blockchain networks.

In its announcement, Manta said it chose to migrate to Polygon CDK for three reasons. First, with Polygon CDK, deposits and withdrawals can be processed quickly, as they don’t require a period of time for fraud proofs to be submitted. “Finality can happen in minutes or seconds, rather than days,” the announcement stated. This is because “CDK leverages the security of math rather than the social-economic incentives of fraud proofs.”

Secondly, Manta claimed that Polygon CDK is more “modular” and “sovereign” than alternatives, giving the team more flexibility as it continues to build out features. Thirdly, using Polygon CDK will allow developers to create a “trustless ZK bridge to Ethereum.” Over the long run, this bridge will allow users of different Polygon CDK networks to access each other’s liquidity, making the network part of a larger ecosystem.

The Polygon ecosystem originally consisted of just the Polygon Proof of Stake network. On March 27, the Polygon team launched a second network, Polygon zkEVM. In June, they announced plans to integrate these two networks into a new ecosystem called “Polygon 2.0.”

The Optimism ecosystem added a second network on August 9, as Coinbase launched Base network. On October 3, the Optimism team launched a fraud-proof system that's intended to be used throughout its ecosystem.

Polygon 2.0 — MATIC conversion to POL outlined in preliminary improvement proposals

The Ethereum layer-2 developer has introduced the first improvement proposals to begin the transition to its Polygon 2.0 ecosystem.

Polygon Labs’ vision of an interconnected layer-2 Ethereum ecosystem powered by zero-knowledge cryptography begins in earnest following three inaugural improvement proposals that will begin the transition to Polygon 2.0.

The scaling technology firm unveiled Polygon 2.0 in June 2023, outlining plans for a scaling ecosystem made up of four protocol layers. The staking, interop, execution and proving layers all play a role in creating an interconnected ecosystem of chains that enable fast value transfer and information sharing.

Polygon co-founder Sandeep Nailwal recently unpacked how the ecosystem aims to become the value layer of the internet by using zero-knowledge (ZK) technology to provide low-fee, high-throughput performance to the wider Ethereum ecosystem.

Polygon released three Polygon Improvement Proposals (PIPs) on Sept. 14 for community consideration and voting that are earmarked to begin taking place in the final quarter of 2023.

The PIPs outline technical details for “Phase 0” of the establishment of a network of interconnected ZK-powered layer-2 chains that scale Ethereum. This includes a proposal for the transition and specifications that will see MATIC (MATIC) tokens become POL tokens, which will become the Polygon proof-of-stake (PoS) protocol’s native token.

PIP-17 will include the initiation of the upgrade from MATIC to POL. This includes its transition to POL as the native gas token and staking token for the Polygon ecosystem, as well as the launch of the staking layer and migration of Polygon public chains.

PIP-18 includes the technical description of POL tokens as well as accompanying contracts that will handle emission and token migrations. POL tokens can be migrated at a 1:1 ratio from existing MATIC tokens. The PIP notes an initial supply of 10 billion and a yearly emission of 2% equally distributed between validator staking rewards and a community treasury.

Lastly, PIP-19 proposes the update of the native gas token on Polygon PoS from MATIC to POL while ensuring maximum backwards compatibility.

Polygon’s announcement notes that PIP-19 will not change contracts on Polygon PoS, while the properties of the protocol’s native token will not change either. However, contracts on Ethereum that are awaiting MATIC from the native MATIC bridge may be affected by the upgrade.

Ethereum’s proto-danksharding to make rollups 10x cheaper – Consensys zkEVM Linea head

Consensys zkEVM Linea head Nicolas Liochon says speed and execution will continue to increase as it tweaks its Ethereum layer 2 scaling solution.

Zero-knowledge proof (ZK-proofs) solutions have proved critical in helping scale the Ethereum ecosystem, but proto-danksharding is expected to drastically reduce the cost of roll ups according to Consensys’ zkEVM Linea head Nicolas Liochon.

Speaking exclusively to Cointelegraph Magazine editor Andrew Fenton during Korea Blockchain Week, Liochon estimated that proto-danksharding could further reduce rollup costs by 10 times.

Proto-danksharding, also known by its improvement proposal identifier EIP-4844, is aimed at reducing the cost for rollups, which typically batch transactions and data off-chain and submit computational proof to the Ethereum blockchain.

The Ethereum Foundation is yet to nail down an expected launch data for proto-danksharding but development and testing is still ongoing

As Liochon explained, Linea delivers 15 times cheaper transactions compared to those made on Ethereum’s layer one, but rollups are still limited by the fact that transactions are posted in calldata in Ethereum blocks.

According to Ethereum’s documentation, rollups are still expensive in terms of their potential because calldata is processed by all Ethereum nodes and the data is stored on chain indefinitely despite the fact that the data only needs to be available for short period.

EIP-4844 will introduce data blocks that can be sent and attached to blocks. The data stored in blobs is not accessible to the Ethereum Virtual Machine and will be deleted after a certain time period - which is touted to drastically reduce transaction costs.

“In reality, the cost of rollups is down to data availability. We are writing all the data to layer one which is why we have exactly the same security. But it’s expensive, it represents 95% of the cost.”

Liochon said that Linea’s prover, which essentially handles the off-chain computation that verifies, bundles and then creates a cryptographic proof of the combined transactions, only represents a fifth of the cost.

This highlights the major hurdle in making ZK-rollups the go-to scaling solution for the Ethereum ecosystem as opposed to other solutions like Optimistic rollups.

Liochon also said that Linea aims to be a general use ZK-rollup that will be used for a variety of decentralized applications and solutions within the Ethereum ecosystem. 

"We are a generic rollup. We don't want to have a specific use case or specific domain. It's quite important to support all type of applications, including DeFi, gaming and social."

As Cointelegraph previously reported, Consensys has completed the launch of Linea in Aug. 2023, having onboarding over 150 partners and bridging more than $26 million in ETH.

ZK-proof Web3 infrastructure developer gets backing from Binance Labs

Delphinus Lab is building a zero-knowledge proof rollup service aimed at powering Web3 application development.

Zero-knowledge proof technology continues to garner interest and investment as Binance Labs becomes the latest firm to invest in ZK-proof powered infrastructure being developed by Delphinus Lab.

Binance’s venture capital arm announced a strategic investment into Delphinus Lab’s zero-knowledge WebAssembly (zkWASM) virtual machine. The zkWASM is being labeled as the first known open-source virtual machine to support ZK computation and application software development kits.

Cointelegraph can exclusively reveal that Binance Labs is investing $2.2 million into Delphinus Lab, with the funds set to facilitate the ongoing development of its application rollup platform zkWASM Hub, which will provide automated proving and batching services for Web3 applications.

WebAssembly (WASM) remains an important cog across the wider internet as a virtual machine that allows code from popular programming languages to be run natively on web browsers. WASM was developed in a collaboration including Google, Mozilla, Microsoft and Apple in 2017.

The infrastructure aims to facilitate the development ZK applications across different developer languages that can be deployed across WASM-supported environments. ZK-proof technology is widely touted to increase the security and privacy of decentralized applications.

The zkWASM Hub will also allow developers to distribute GitHub applications into its ecosystem through its auto compilation and updating service.

Binance Labs also noted that Delphinus Lab has implemented several application-specific software development kits in different languages across multiple applications. This includes dynamic programmable NFTs, fully on-chain games, high-performing trustless Central Limited Order Book (CLOB) and trustless oracles.

A statement from Delphinus Lab founder and CEO Sinka Gao highlighted the firm’s hopes to see Web3 decentralized applications (DApps) created that combine Web2’s “robustness” with Web3s “decentralized, trustless" nature:

"Our zkWASM Hub introduces a streamlined multi-chain execution layer for developers to easily deploy and manage their WASM-backed apps in a dynamic rollup environment.”

Binance Labs also noted that it was looking to employ its venture funds into the wider ecosystem with a focus on projects that enable scalability, while looking into application layers that could onboard more users to Web3.

The spokesperson added that its investment focus was on innovative technology and critical infrastructure that is power new sectors. This includes modular blockchain, liquid staking decentralized finance protocols and ZK-proof solutions.
