Polygon, a layer-2 scaling protocol for Ethereum has launched a zero-knowledge decentralized identity solution, Polygon ID to the public nearly a year after announcing its development. The service uses zero-knowledge proofs (ZK proofs) that use cryptographic techniques to allow users to verify their identity online without having their sensitive information passed, or potentially stored with a third party. The public release of Polygon ID by Polygon Labs on Mar. 1 comes almost 12 months after it was officially launched in a closed-source environment in late March 2022, which the Polygon team says was built to “solve the issue of digital …

The Ethereum community appears to have taken a bullish view of Coinbase’s newly announced layer-2 network, Base, which has been described as a “massive confidence vote” and a “watershed moment” for the blockchain network. Secured on Ethereum and powered by layer-2 network Optimism, Base aims to eventually become a network for building decentralized applications (DApps) on the blockchain. The layer-2 network is currently in its testnet phase, according to Coinbase CEO Brian Armstrong. 0/ Hello world. Meet Base, an Ethereum L2 that offers a secure, low-cost, developer-friendly way for anyone, anywhere, to build decentralized apps. Our goal with Base is …

The long-awaited scaling upgrade from Ethereum layer-2 solution provider Polygon (MATIC) has been announced, with the Beta launch of its zero-knowledge Ethereum Virtual Machine (zkEVM) mainnet slated for Mar. 27. In a Feb. 14 blog post, Polygon said after three and a half months of "battle testing," the system will be ready for the mainnet next month. Roses are red Violets are blue Poems are hard Mainnet Beta is here ON MARCH 27, Polygon #zkEVM launches the future of Ethereum scaling https://t.co/OqSOYTn8Uv pic.twitter.com/kpXavea3ff — Polygon (@0xPolygon) February 14, 2023 It's been touted as “seamless scaling for Ethereum," and was launched …

App-specific blockchains, or appchains, are specifically designed to support the creation and deployment of decentralized applications (DApps). In an appchain, each app runs on its separate blockchain, linked to the main chain. This allows for greater scalability and flexibility, as each app can be customized and optimized for its specific use case. Appchains are also an alternative solution for scalability to modular blockchains or layer-2 protocols. Appchains present similar characteristics to modular blockchains, as it is a type of blockchain architecture that separates the data, transaction processing and consensus processing elements into distinct modules that can be combined in various …

Ethereum layer-2 scaling protocol Polygon (MATIC) is carrying out performance testing of zero-knowledge rollup (zk rollups) technology ahead of full integration with its mainnet. The development of the technology, called Polygon zkEVM (Ethereum Virtual Machine), has been ongoing for over three years by the Polygon Hermez team. The team has already confirmed that zero-knowledge proofs are possible on Ethereum, by generating over 12,000 zk-proofs in a primary version of the zkEVM testnet. David Schwartz, project lead of Polygon zkEVM and PolygonID, unpacked the development of the functionality in correspondence with Cointelegraph. Layer-2 platforms have continued to evolve and improve functionality …

Input Output Global (IOG) — the team behind the Cardano ecosystem — will release a software toolkit in late Jan. 2023 that will enable developers to deploy custom-built sidechains on Cardano aimed at improving the ecosystem. The news was announced by IOHK — a blockchain engineering company founded by Charles Hoskinson and now known as IOG — on Jan.12, which also attached the official technical documentation for the sidechain toolkit. ⛓️ The #Cardano sidechain toolkit was previewed at #IOScotFest, and we’re happy to share the first iteration is out now. Here’s the lowdown on this exciting new project! https://t.co/Ny9tQuJh5K — …

Ethereum Layer-2 (L2) on-chain activity has been increasing to the extent that the leading two networks now process more transaction volume than the Ethereum network. Layer-2 networks Arbitrum and Optimism have seen an increase in transactions over the past three months. Comparatively, aside from a few spikes, transactions on the Ethereum network have declined by around 33% since late October according to Etherscan. This has enabled the two L2s combined to flip Ethereum for this metric, according to Dune Analytics data. The chart shows Ethereum processed over 1.06 million transactions on Jan. 10 whereas Arbitrum and Optimism combined processed over …

Arguably the most popular blockchain amongst developers building decentralized applications (dApps), the Ethereum Network is credited with introducing the Web3 community to innovations like smart contracts while maintaining robust security standards. However, in order to solve Ethereum’s scalability issue, a new type of Layer-2 (L2) blockchain was introduced that relies on the Ethereum Mainnet (Layer-1) for its security but processes transactions on separate third-party networks in order to increase throughput speeds. EVM compatibility for higher transaction speeds Importantly, developers had to ensure that these L2 blockchains were compatible with the Ethereum Virtual Machine (EVM), a run-time environment where Ethereum’s application …

Web3 investment firm Paradigm has released a Rust implementation of Ethereum, according to a Dec. 7 announcement from the company’s chief technology office, Georgios Konstantopoulos. The new software, called “Reth,” allows Ethereum validators to launch their nodes using Rust instead of Go, Java, or other languages. A previous Rust implementation had been released by Erigon in June, but the Erigon team stopped supporting it in November when they learned that Reth was under development, according to a post by the Erigon team. In the announcement, Konstantopoulos stated that the software has been released in order to “[contribute] to Ethereum’s stability …

United States technology company IBM and Danish logistics firm Maersk have decided to discontinue their co-developed blockchain-backed supply chain platform, TradeLens, citing a lack of “global industry collaboration” as a key reason behind the decision. Maersk stated on Nov. 29 that it has begun taking immediate action to cease operations on the platform which should take full effect by Q1 2023: “The TradeLens team is taking action to withdraw the offerings and discontinue the platform [...] During this process all parties involved will ensure that customers are attended to without disruptions to their businesses.” While the blockchain-based shipping solution was …

Zero-knowledge (ZK)-Rollup tech company StarkWare has officially open sourced its new programming language compiler, Cairo 1.0, which will soon be supported on Ethereum layer-2 scaling solution StarkNet in Q1 2023. The news was announced by StarkWare — the company behind StarkNet — in a Nov. 25 Twitter post. StarkWare’s rollup technology and recursive proofs offer the potential to compress millions of transactions on L2 into a single transaction on Ethereum, however the project has been criticized for maintaining control over its IP, not least of all by its more open source focused competitor zkSync. StarkWare described open sourcing Cairo as …

Matter Labs, the developer behind the Ethereum Virtual Machine (EVM)-compatible zkSync, has received major industry backing as it pledges to fully open source its platform — marking the first such initiative for a ZK-rollup technology. Matter Labs confirmed on Nov. 16 that it had closed a $200 million Series C funding round co-led by Blockchain Capital and Dragonfly, with additional participation from LightSpeed Venture Partners, Variant and existing investor Andreessen Horowitz. The company has now raised $458 million in financing across all rounds, including $200 million from BitDAO that’s earmarked for funding ecosystem projects. Founded in 2018, Matter Labs is …
