Polygon Unveils $ZkEVM, ‘The Holy Grail of Scaling’

The technology will reduce transaction costs and greatly increase throughput on a layer-2 rollup which inherits the security of Ethereum, the Polygon team says

When it comes to scaling Ethereum, Polygon has taken an everything-and-the-kitchen-sink approach.

Its logo may be a hexagon, but Polygon already maintains seven discrete teams building an interrelated web of products.

Three of those teams, Hermez, Zero and Miden, have worked together to create zkEVM — a zero-knowledge proof-based rollup which achieves equivalence with the Ethereum virtual machine (EVM), which the Polygon team defines as EVM specification-level compatibility.

That means developers can easily deploy applications written in Solidity — Ethereum’s smart contract language — and take advantage of the ecosystem’s robust developer tools, just as they do on the Ethereum mainnet.

The move Wednesday, at the Ethereum Community Conference in Paris, heralds the imminent launch of a zkEVM testnet, a goal set by the Hermez team at the same conference a year ago.

“It’s been a long journey — I can talk in personal terms — this has been the project of my life,” said Jordi Baylina, technical lead at Polygon Hermez, during the group’s #PolygonTuesdays weekly Twitter space, last week. “Scaling Ethereum, scaling blockchains, has been the dream since at least 2015 if not before.”

Rollups based on zero-knowledge proofs have several advantages over the optimistic rollups which are already up and running, such as Optimism and Arbitrum — the two largest by total value locked.

Zero-knowledge rollups combine many layer-2 transactions into one — which settle on Ethereum as a validity proof. While computationally intensive, zero-knowledge rollups are much faster and more scalable.

“It makes Ethereum almost technically or theoretically infinitely scalable,” Polygon’s Sandeep Nailwal said during the Twitter space, adding that in contrast to other solutions, only Ethereum itself is needed. “It has network effects. It has developers. It has users, so you know we can take Web3 to the next stage of growth,” he said.

Other projects are working on EVM-compatible or EVM-equivalent zero-knowledge rollups, such as Scroll and Matter Lab’s zkSync, but Polygon has a significant funding edge thanks to its $450 million raise in February.

A closed testnet of Polygon’s zkEVM should be available within two weeks with a public permissionless testnet to follow a few weeks later, Polygon co-founder Mihailo Bjelic told Blockworks. The product is expected to reach the Ethereum mainnet by year’s end. Major Web3 applications such as Uniswap are planning to deploy on zkEVM.

“A future configuration of off-chain data availability will be able to reduce the fees further,” Bjelic said.

Polygon Avail envisions sovereign rollup chains
While zkEVM is “a proper old-school rollup,” Bjelic said, potentially significant efficiency gains are possible by using an off-chain data availability solution, such as Polygon Avail.

Avail is an entirely new blockchain focused on data availability that fits into a framework for scalability known as “modular” — as opposed to monolithic, such as Ethereum is today, where execution, data availability and settlement all occurs on the same layer.

In a rollup, 70% to 85% of the cost is attributed to storing Ethereum call data, Avail lead Anurag Arjun told Blockworks.

“That component can move to Avail,” he said.

Doing so would transform zkEVM into what’s known as a validium.

“Everyone is really looking for lower transaction fees, if the security can be maintained,” Arjun said. “You will see every rollup — at least in my opinion — will have a rollup version and a validium version.”

ZkEVM is a likely candidate for upgrading the existing Polygon proof-of-stake chain — the Ethereum-aligned sidechain using the MATIC token that was Polygon’s first foray into Ethereum scaling.

“That’s probably the end goal,” Bjelic said.

A team at Polygon is working on a way to migrate the entire proof-of-stake chain into a future version of the zkEVM in a way which would not require dApp developers or users to take any action. But such a solution is still about a year away.

“Polygon is a multichain ecosystem. We believe there will be probably thousands such chains built on top of Ethereum,” Nailwal said, stressing the open-source nature of all the company’s development efforts. “Cryptography must be open to be safe…Whatever we are building is for the public good and everything will be open source and will be in the public domain.”

The Great Onboarding: US Government Anchors Global Economy into Web3 via Pyth Network

For years, the crypto world speculated that the next major cycle would be driven by institutional adoption, with Wall Street finally legitimizing Bitcoin through vehicles like ETFs. While that prediction has indeed materialized, a recent development signifies a far more profound integration of Web3 into the global economic fabric, moving beyond mere financial products to the very infrastructure of data itself. The U.S. government has taken a monumental step, cementing Web3's role as a foundational layer for modern data distribution. This door, once opened, is poised to remain so indefinitely.

The U.S. Department of Commerce has officially partnered with leading blockchain oracle providers, Pyth Network and Chainlink, to distribute critical official economic data directly on-chain. This initiative marks a historic shift, bringing immutable, transparent, and auditable data from the federal government itself onto decentralized networks. This is not just a technological upgrade; it's a strategic move to enhance data accuracy, transparency, and accessibility for a global audience.

Specifically, Pyth Network has been selected to publish Gross Domestic Product (GDP) data, starting with quarterly releases going back five years, with plans to expand to a broader range of economic datasets. Chainlink, the other key partner, will provide data feeds from the Bureau of Economic Analysis (BEA), including Real Gross Domestic Product (GDP) and the Personal Consumption Expenditures (PCE) Price Index. This crucial economic information will be made available across a multitude of blockchain networks, including major ecosystems like Ethereum, Avalanche, Base, Bitcoin, Solana, Tron, Stellar, Arbitrum One, Polygon PoS, and Optimism.

This development is closer to science fiction than traditional finance. The same oracle network, Pyth, that secures data for over 350 decentralized applications (dApps) across more than 50 blockchains, processing over $2.5 trillion in total trading volume through its oracles, is now the system of record for the United States' core economic indicators. Pyth's extensive infrastructure, spanning over 107 blockchains and supporting more than 600 applications, positions it as a trusted source for on-chain data. This is not about speculative assets; it's about leveraging proven, robust technology for critical public services.

The significance of this collaboration cannot be overstated. By bringing official statistics on-chain, the U.S. government is embracing cryptographic verifiability and immutable publication, setting a new precedent for how governments interact with decentralized technology. This initiative aligns with broader transparency goals and is supported by Secretary of Commerce Howard Lutnick, positioning the U.S. as a world leader in finance and blockchain innovation. The decision by a federal entity to trust decentralized oracles with sensitive economic data underscores the growing institutional confidence in these networks.

This is the cycle of the great onboarding. The distinction between "Web2" and "Web3" is rapidly becoming obsolete. When government data, institutional flows, and grassroots builders all operate on the same decentralized rails, we are simply talking about the internet—a new iteration, yes, but the internet nonetheless: an immutable internet where data is not only published but also verified and distributed in real-time.

Pyth Network stands as tangible proof that this technology serves a vital purpose. It demonstrates that the industry has moved beyond abstract "crypto tech" to offering solutions that address real-world needs and are now actively sought after and understood by traditional entities. Most importantly, it proves that Web3 is no longer seeking permission; it has received the highest validation a system can receive—the trust of governments and markets alike.

This is not merely a fleeting trend; it's a crowning moment in global adoption. The U.S. government has just validated what many in the Web3 space have been building towards for years: that Web3 is not a sideshow, but a foundational layer for the future. The current cycle will be remembered as the moment the world definitively crossed this threshold, marking the last great opportunity to truly say, "we were early."

US Dept of Commerce to publish GDP data on blockchain

On Tuesday during a televised White House cabinet meeting, Commerce Secretary Howard Lutnick announced the intention to publish GDP statistics on blockchains. Today Chainlink and Pyth said they were selected as the decentralized oracles to distribute the data.

Lutnick said, “The Department of Commerce is going to start issuing its statistics on the blockchain because you are the crypto President. And we are going to put out GDP on the blockchain, so people can use the blockchain for data distribution. And then we’re going to make that available to the entire government. So, all of you can do it. We’re just ironing out all the details.”

The data includes Real GDP and the PCE Price Index, which reflects changes in the prices of domestic consumer goods and services. The statistics are released monthly and quarterly. The biggest initial use will likely be by on-chain prediction markets. But as more data comes online, such as broader inflation data or interest rates from the Federal Reserve, it could be used to automate various financial instruments. Apart from using the data in smart contracts, sources of tamperproof data 👉will become increasingly important for generative AI.

While it would be possible to procure the data from third parties, it is always ideal to get it from the source to ensure its accuracy. Getting data directly from government sources makes it tamperproof, provided the original data feed has not been manipulated before it reaches the oracle.

List Of Cardano Wallets

Well-known and actively maintained wallets supporting the Cardano Blockchain are EternlTyphonVesprYoroiLaceADAliteNuFiDaedalusGeroLodeWalletCoin WalletADAWalletAtomicGem WalletTrust and Exodus.

Note that in case of issues, usually only queries relating to official wallets can be answered in Cardano groups across telegram/forum. You may need to consult with specific wallet support teams for third party wallets.

Tips

  • Its is important to ensure that you're in sole control of your wallet keys, and that the keys used can be restored via alternate wallet providers if a particular one is non-functional. Hence, put extra attention to Non-Custodial and Compatibility fields.
  • The score column below is strictly a count of checks against each feature listed, the impact of specific feature (and thus, score) is up to reader's descretion.
  • The table represents current state on mainnet network, any future roadmap activities are out-of-scope.
  • Info on individual fields can be found towards the end of the page.
  • Any field that shows partial support (eg: open-source field) does not score the point for that field.

Brief info on fields above

  • Non-Custodial: are wallets where payment as well as stake keys are not shared/reused by wallet provider, and funds can be transparently verified on explorer
  • Compatibility: If the wallet mnemonics/keys can easily (for non-technical user) be used outside of specific wallet provider in major other wallets
  • Stake Control: Freedom to elect stake pool for user to delegate to (in user-friendly way)
  • Transparent Support: Easy approachability of a public interactive - eg: discord/telegram - group (with non-anonymous users) who can help out with support. Twitter/Email supports do not count for a check
  • Voting: Ability to participate in Catalyst voting process
  • Hardware Wallet: Integration with atleast Ledger Nano device
  • Native Assets: Ability to view native assets that belong to wallet
  • dApp Integration: Ability to interact with dApps
  • Stability: represents whether there have been large number of users reporting missing tokens/balance due to wallet backend being out of sync
  • Testnets Support: Ability to easily (for end-user) open wallets in atleast one of the cardano testnet networks
  • Custom Backend Support: Ability to elect a custom backend URL for selecting alternate way to submit transactions transactions created on client machines
  • Single/Multi Address Mode: Ability to use/import Single as well as Multiple Address modes for a wallet
  • Mobile App: Availability on atleast one of the popular mobile platforms
