Our testnet on Goerli is 100% permissionless. Here are the details: [![Like Icon](https://paragraph.xyz/editor/twitter/heart.png) 1,506](https://twitter.com/Scroll_ZKP/status/1630258973856395264)[ 12:30 PM • Feb 27, 2023 ](https://twitter.com/Scroll_ZKP/status/1630258973856395264) While most of the recent zkEVM talk has been centered around Polygon & zkSync over the past couple of months, there’s been one project quietly building its own zkEVM, Scroll.   Last Monday, Scroll announced the launch of their zkEVM Alpha testnet on Goerli. This essentially means that any user can add the Scroll zkEVM network to their wallet and start playing around with some of the dapps that have already been deployed. To recap, a zkEVM adds zero-knowledge cryptography to the Ethereum virtual machine. While ZK tech is mainly used for scaling purposes (viewed as the holy grail for Ethereum scaling), it also allows for privacy capabilities. Privacy is not only important for us individual users, but for businesses that want to keep their company data private. Today, StarkWare is probably the team best known for its use of ZK technology, as they’ve had a working zkVM for some time now (see StarkEx & StarkNet). However, StarkWare doesn’t use the EVM, but rather its own architecture (CairoVM & Cairo programming language), which in turn leads to its own set of tools. Adding ZK tech to the EVM lets developers add scalability to their dapps, translating to high speeds and low fees for us users, while being able to utilize the Solidity programming language and existing tools like Metamask. This means existing Solidity-based dapps will be able to easily port their code to Scroll. zkEVMs were expected to be years away. However, we now have three different projects expected to release a permissionless version of their zkEVM on mainnet this year (Scroll, Polygon & zkSync). For anyone interested in playing around with Scroll’s testnet, simply: * Add the Goerli testnet network to your wallet * Request testnet ETH from a faucet * Add the Scroll zkEVM network to your wallet (make sure it’s the correct one!) * Head over to Scroll’s bridge interface and bridge your testnet ETH from Goerli to the Scroll network  * & that’s it, you can start playing around with some of the dapps currently running on the zkEVM testnet, like [Uniswap](https://gaurangtorvekar.medium.com/how-to-use-uniswap-on-scroll-alpha-testnet-d41c1b1276e6) or Tic-Tac-Toe!

This is Scroll’s last big milestone before they reach full mainnet launch. Congrats to the entire Scroll team! * * * ERC-4337 -------- [![User Avatar](https://pbs.twimg.com/profile_images/1270073276740534274/APmUBHaI_normal.jpg)](https://twitter.com/Cointelegraph) [Cointelegraph](https://twitter.com/Cointelegraph) [@Cointelegraph](https://twitter.com/Cointelegraph) [![Twitter Logo](https://paragraph.xyz/editor/twitter/logo.png)](https://twitter.com/Cointelegraph/status/1631036968263090176) The new ERC-4337 "account abstraction" standard will be launched at WalletCon in Denver today. It provides Ethereum accounts with all the features of a bank account: 2FA, password recovery and set spending limits.

Not to get confused with EIPs, which are hard forked into the actual protocol, ERCs are smart contracts that hold standards by which developers follow. The biggest example of an ERC is ERC-20 tokens, which set the standard for how fungible tokens are created on Ethereum. As mentioned, ERC-4337 introduces Account Abstraction, which “allows users to use smart contract wallets containing arbitrary verification logic instead of EOAs as their primary account”. In short, this means we can start adding logic to our individual wallet accounts (2FA, FaceID, etc.). There are two Account types on Ethereum, Externally Owned Accounts (EOAs), and Contract Accounts. Today, we use EOAs, which are controlled by private keys, however, account abstraction introduces contract accounts, which are accounts controlled by a smart contract rather than a private key. Because accounts are represented by smart contracts, developers are able to add their own logic, enabling end users to benefit from extra security features. To be a little more specific, there are three major components that go into our account’s security: Authentication, Replay protection, and Payment. With contract accounts, you can abstract away some of the features that go into these three components, whether that means adding a recovery method, adding multiple signers to your account, etc. You can watch [this great presentation](https://www.youtube.com/watch?v=xHWlJiL_iZA) about ERC-4337 to learn all about this new standard and what exactly is being “abstracted away.” Some account abstraction use cases include: * **Social recovery:** use a separate wallet (the ledger in your vault) to recover access to your lost wallet * **Session keys:** you can have different keys for different purposes within one account. So, you can use one key to interact with a game using your assets, and another to actually sell/trade your game items. * **Paymasters:** allows teams to choose a separate account to take care of gas fees, as opposed to having the end platform users pay (gasless transactions by having the dapp itself pay for fees) * **Authentication:** add 2FA, FaceID, Social log-in, or any other form of authentication mechanism, & much more! Account Abstraction has been highly anticipated for some time now. Over the following year, we should expect existing smart contract wallets like Argent and Braavos expand to multiple chains, as well as Metamask and other traditional Ethereum EVM wallets to add account abstraction support. Plus, what is even more exciting is that we’ll probably see other EVM networks like Arbitrum, Optimism, and Polygon add support too! There are tons of use cases that are enabled by account abstraction, If you’d like to dig deeper into the subject, we recommend [this amazing paper](https://camiinthisthang.substack.com/p/account-abstraction-for-everyone?r=1pdk1u&utm_campaign=post&utm_medium=email) written by [Cami.](https://twitter.com/camiinthisthang) * * * AltLayer’s 100 Flash Layers Campaign Begins ------------------------------------------- [![User Avatar](https://pbs.twimg.com/profile_images/1522219377470640128/uf3uNfCq_normal.jpg)](https://twitter.com/alt_layer) [AltLayer](https://twitter.com/alt_layer) [@alt\_layer](https://twitter.com/alt_layer) [![Twitter Logo](https://paragraph.xyz/editor/twitter/logo.png)](https://twitter.com/alt_layer/status/1631558603571118084) No-code Rollups-as-a-Service are HERE.

To recap, Altlayer is building a system of disposable, optimistic rollups, or as they refer to them, _“Flash Layers”_. Using their dashboard, users will be able to deploy their own custom, no-code rollup in just ten minutes. They currently support rollups on Ethereum and other EVM chains but will expand to other environments in the future.  From February 10-28th, they allowed anyone to apply for a chance to be among the 100 people/teams to try the rollup launchpad. Now that registrations are out of the way, the 100 chosen experimentoors have until March 10th to launch their own disposable rollup. Those who were chosen for the campaign should have received an email by now. There are several use cases for disposable, or short lived rollups, mostly revolving around the gaming/NFT space. For example, disposable rollups can be used by individual NFT collections that want to have their mint take place on its own environment, thereby removing congestion, which then removes gas wars. Or by builders who want to launch their own mini or Indie game. The point is to use flash layers for projects that don’t need to be running a chain for more than a certain period of time (Yuga launching Dookey Dash on its own short lived rollup for example). Since the campaign started, there have been several deployed public rollups for users to interact with, including the “Dragon Eyes” NFT collection launch, and “Mother Staker”, an ERC-20 token staking platform. For anyone interested in testing out AltLayer, [here’s](https://100fl-showcase.altlayer.io/) a complete set of public projects you can start using.

In fact, here’s [a demo](https://twitter.com/dferrersan/status/1632783043210670087) of the EVM running on Bitcoin as a sovereign rollup!   As a reminder, there are three layers that go into a blockchain: execution layer, settlement layer, and DA/Consensus layer. A monolithic chain includes these three components into a single layer, whereas modular chains separate them into their own layers.  Rollkit enables developers to plug in custom execution and data availability layers in order to create the rollup best suited for their own particular dapp. For example, it allows developers to choose their preferred virtual machine (EVM or SVM), gas token (pay gas in ETH, USDC, etc), along with any other features for their execution environment, as well as their own data availability solution. Celestia was the first DA solution to be added to the stack, but just two days ago, Bitcoin was added as another option, enabling developers to start building sovereign rollups on Bitcoin.  There’s been a lot of talk & debate going on in crypto Twitter regarding this recent announcement, but regardless of what anyone thinks, at least people are talking about rollups on Bitcoin now.

This could be a bartender verifying you’re over the age of 21 for example, and because Polygon ID uses zk-technology, you won’t even have to show your birth date, just the proof of VC ownership (a QR code) _Now let’s look at some of the use cases Polygon ID enables:_ * **Lending:** A lending protocol could integrate the ID solution to enable uncollatoralized lending.  * **Ticketing/Events:** Enable NFT collectors to start attending token gated events wqithout having to actually carry their wallet that holds their NFTs with them. Yuga could offer VCs for ape ownership, carry that proof (not the JPEG) in your Polygon ID wallet, and use that VC to access the event.  Polygon ID has been in development for several years now, but it looks like starting this year, we’ll start seeing this new tool be used across the Polygon ecosystem. Polygon ID was originally known as the Iden (Identity) protocol, and was founded by the same original team behind Hermez, or what is now referred to as Polygon zkEVM. As a reminder, Polygon acquired Hermez, along with the team and their identity solution about a year ago, in what was part of their $1B effort to expand their zk stack. We’re excited to see what developers build over time with Polygon ID.

The EVM was definitely not designed to be proven. [Micah makes two main points](https://twitter.com/MicahZoltu/status/1631136350236983296?s=20). He says it’ll be hard for zkEVMs to: * Be cost competitive * Have good developer UX (e.g. [loops are hard to prove](https://twitter.com/MicahZoltu/status/1631144484426874886?s=20)) No surprise - ZK teams don’t agree. Here are some of their responses: * [Polygon zkEVM has](https://twitter.com/MihailoBjelic/status/1631240168697995265?s=20) ~ L1-equivalent UX and proving costs of $1.90 per hour (not very costly) * [Teams have gotten around](https://twitter.com/yezhang1998/status/1631619236601659394?s=20) developer UX hurdles like proving loops * Being able to port battle tested smart contract code [is good developer UX](https://twitter.com/yezhang1998/status/1631622604510339074?s=20) It appears the basis of Micah’s argument is outdated, which he’s willing to concede.

Maybe someone has solved this since I last looked?

And at first glance it seems obvious that they are - a 230,000x multiple is insane. But does that mean we should write them off completely? Not sure. Like any startup, protocols will balance growth vs. monetization. Growth can mean a number of things - mindshare, users, etc. - even if users are temporarily subsidized. The key word, though, is temporarily. If you want to stick with the corporate analogy, each protocol needs a monetization strategy that eventually gets executed. If you want to think about it in a more nuanced and crypto-native way, check out [Jon Charb’s recent article](https://joncharbonneau.substack.com/p/eth-is-not-ultrasound-money-part). So which L1s have plausible strategies? There are arguments to make for some. [Cosmos Hub, for example](https://twitter.com/EffortCapital/status/1630329907061436416?s=20), has interesting demand drivers for both growth and monetization: * Cosmos [narratives gaining momentum](https://medium.com/1kxnetwork/application-specific-blockchains-9a36511c832) * [Replicated Security](https://twitter.com/cosmoshub/status/1627705291637678088?s=20) gives ATOM a value accrual mechanism * Cosmos Hub [alignment with modular ecosystem](https://twitter.com/nickwh8te/status/1581001244071854080?s=20) If you want to take this exercise a few steps further, Polynya created a pretty comprehensive framework that can be mapped to any protocol: [![User Avatar](https://pbs.twimg.com/profile_images/1626405010224611329/jmLpEBZz_normal.jpg)](https://twitter.com/apolynya) [polynya](https://twitter.com/apolynya) [@apolynya](https://twitter.com/apolynya) [![Twitter Logo](https://paragraph.xyz/editor/twitter/logo.png)](https://twitter.com/apolynya/status/1610872977847115777) Just some of the ways ETH is used beyond just staking. LSDs help, but the idea should be to have as little staked as possible while still maintaining adequate economic security - so ETH can be actually used. A 61% staking rate just implies the asset isn't very useful. ![](https://pbs.twimg.com/media/Flr38aXaUAMSaFA.png) [![Like Icon](https://paragraph.xyz/editor/twitter/heart.png) 160](https://twitter.com/apolynya/status/1610872977847115777)[ 12:37 AM • Jan 5, 2023 ](https://twitter.com/apolynya/status/1610872977847115777) * * * More Discussions & Education ---------------------------- * [@jbaylina explains](https://twitter.com/jbaylina/status/1629352597445394432?s=20) why ZK rollups are not bottlenecked by provers * [@toghrulmaharram clarifies](https://twitter.com/toghrulmaharram/status/1629356500555628546?s=20) why ZK provers aren’t bottlenecks, [agreeing with @jbaylina](https://twitter.com/jbaylina/status/1629352597445394432?s=20) 👆 * [@TaschaLabs hosts](https://twitter.com/TaschaLabs/status/1629637478188732417?s=20) Sreeram from EigenLayer to discuss how restaking can scale PoS and change staking yield on Ethereum * [@stonecoldpat0 writes](https://twitter.com/stonecoldpat0/status/1631357986001018884?s=20) an article discussing numerous different rollup designs * [Messari compares](https://twitter.com/MessariCrypto/status/1631678346722529282?s=20) the time to finality (TTF) of popular blockchains * [Bankless hosts](https://open.spotify.com/episode/0LPERpCrv9Yz6Q7ZFWWWDr?si=xZikzOrZQ4yFUa2cwlWKYQ) the OP Labs founders to discuss Base * [Bell Curve releases](https://open.spotify.com/episode/5nYMsiU9ewUpmmcVhtARHg?si=VBAPux99QsKHiAn83HD4XA) an episode discussing Base * [Eclipse explains](https://twitter.com/EclipseFND/status/1630269421494337541?s=20) how EigenLayer impacts rollups and modular blockchains * [@dannyryan reflects](https://twitter.com/dannyryan/status/1628951558896640000?s=20) on his experience building Ethereum -
