You can check out our previous newsletter issue [here](https://paragraph.xyz/@modularmedia/weekly-rollup-9). * * * 📣 News & Announcements ======================= Ethereum Upgrades to Shapella ----------------------------- Ethereum’s highly anticipated Shapella hard fork officially took place on April 12th at around 6:30 PM PST. This was the first hardfork since Ethereum’s merge to proof of stake. While there were several changes that came along with this new upgrade, the main focus was on $ETH withdrawals.  As you may already know, anyone can run their own Ethereum validator node and start contributing to the network's security. The incentive for providing your ETH stake is the ETH rewards that come from both transaction fees (user gas fees) and block rewards (newly minted ETH).  In order to run a validator however, the user needs to stake his/her own ETH into the Beacon chain (Ethereum’s PoS network) smart contract. Each validator node requires a stake of 32 ETH.  Those of us who were not able to meet this 32 ETH requirement have simply headed over to a liquid staking solution, such as Lido or Rocket Pool, and taken part in contributing towards Ethereum’s security this way. What these solutions do is pool together user funds until the 32 ETH requirement is met. For every pool of 32 ETH they create, they spin up a new validator node for the Ethereum network.  Whenever users deposit their ETH into these liquid staking solutions, they receive a corresponding token in return (stETH, rETH, etc.) that represents the original user deposit. So for example, if I deposit 10 ETH into Lido, I get 10 stETH in return. Holding this token allows me to accrue validator rewards while giving me the opportunity to exit at any time by simply swapping the stETH (or rETH, etc.) back for regular unstaked ETH.  This is why the Shapella upgrade was a much bigger deal for solo stakers (those who run their own home validator node).  That being said, there are some interesting questions that come to mind when it comes to liquid staking solutions, such as: * Will we see more users withdraw their assets from liquid staking solutions in order to run their own solo setup, now that they can rest assured knowing they can withdraw at any time * We may soon see these solutions develop a mechanism for the automatic staking of issuance rewards. Will most users opt in for this?  **Numbers so far** ![](https://storage.googleapis.com/papyrus_images/8f8bae9ec0b1c3dcd3095dadff24c87e.jpg) As we can see from the chart above, total staked ETH is down since withdrawals were activated, coming down about 1M ETH, now settling at 17,401,375.  Total staked ETH was of course expected to come down following the hard fork, considering the pent-up demand spanning two years now. What was not as expected was for deposits to immediately come back up and outweigh withdrawals so soon, as we can see below: ![](https://storage.googleapis.com/papyrus_images/dcc334f65bd7a7a9ff8e0a033b7c72f5.png) You can check out the stats for yourself [here](https://query.nansen.ai/public/dashboards/Hk93n66vsO0uvycfui8ypF2xcpNhpraxfwX5AWZJ?utm_campaign=shanghaiupgrade_12apr23&utm_medium=social&utm_source=twitter).  In regards to the price of ETH, many expected this to fall dramatically, however, this was not the case at all. In fact, ETH has been up only ever since: ![](https://storage.googleapis.com/papyrus_images/217e2dc75352b730ef8ceadf34fc190b.jpg) **What’s next for Ethereum?** Now that Shapella is out of the way, the focus for the Ethereum Foundation is now set on Cancun-Deneb, which is the next hard fork and will introduce EIP-4844, or proto-danksharding. Of course, this topic is for future discussion. It’s amazing to see Ethereum reach all these milestones. Congrats to the entire team of people who helped bring this upgrade to life! * * * **Introducing the Stackr SDK** ------------------------------ Last week, Stackr Labs officially introduced the Stackr SDK, which is a framework that enables developers to launch their own application-specific “micro-rollups” using traditional general-purpose programming languages such as Python and JavaScript, Go, C, Rust, and more.  As a reminder, rollups are a type of off-chain scaling solution that takes a bunch of user transactions, bundles them up (rolls them up), computes them off-chain, and then the results of the computations and data are stored on-chain (on the base layer the rollups is built on top of).  Most rollups we’re accustomed to today are general-purpose rollups, such as Arbitrum and Optimism. The problem with general-purpose blockchains however is that dapps are sharing computational resources and blockspace with one another. Aside from this, dapps under a general-specific rollup have to abide by the rules of that rollup, for example, having to use the EVM within Arbitrum. That being said, there has been a big pivot towards favoring application-specific rollups now. With app-specific rollups, each dapp is its own rollup, meaning it gets its own blockspace, it can set its own rules, and much more, rather than being tied to the rules of a general purpose rollup.  The problem however is having to build your own rollup from the ground up. This is where rollup framework solutions like Stackr come into play.  **What is Stackr** Stackr provides developers with different modular components that can be put together to build a rollup that suits the specific needs of each individual team. In other words, each team can build its own customized, dedicated rollup (execution environment) in minutes, rather than in months or years. This means you only focus on your dapp, not on how the underlying cryptography works.  Over time, the Stackr team will add more and more modules for developers to choose between, such as, do you want to use fraud proofs or zk-proofs, or do you want a sovereign rollup or a settled rollup, etc.  Each rollup within the Stackr ecosystem will be able to have seamless interoperability with each other thanks to the use of a “shared aggregator”. You can think of the aggregator as a bundler. In short, this shared aggregator receives a bunch of data from different apps (rollups), bundles that data, and submits it on-chain. So, a dapp written in Python for example, will be able to communicate with a JavaScript written dapp, or with a C written dapp, etc. You can see a visual example of how this will look down below: ![](https://storage.googleapis.com/papyrus_images/a8838b93b5cd591fd912312b2a835eec.jpg) **How are they different than others?** If you’ve been following Modular Media for a while now, you’ll know that there are several teams working on making rollups accessible to all. That said, there are generally two different approaches teams are taking. There are teams like Caldera and AltLayer who are working on rollups-as-a-service. This approach compares to a hosting company - you just deploy your contract in a single click (usually) and they take care of managing your rollup and everything. On the other hand, there are teams like Rollkit and Stackr who are building Rollup SDKs. These are not 1-click solutions that take care of managing your rollup or hosting, but rather, they provide developers with a set of modules that developers can choose between (a fraud proof module or zk-proof module for example). This does require a bit more developer experience, however, the reward is more control over your rollup.  However, Stackr separates itself from the rest of the pack even further by being the only solution focused on bringing traditional web2 programming languages to web3, such as Python and JavaScript.  As we can see from the [images below](https://twitter.com/0xDinoEggs/status/1645538257030217729), there’s a big discrepancy between the number of web2 developers vs web3. Rather than continuing to try and bring web2 to web3, Stackr is taking the approach of taking web3 to web2, by using the tools most developers are already familiar with. ![](https://storage.googleapis.com/papyrus_images/ba00247634f376cbf64df18a00e25914.jpg)![](https://storage.googleapis.com/papyrus_images/3e3a91ebec379c8d4de8a799bd32fa52.jpg) **What’s next** According to the team, “the SDK will also be as flexible as possible regarding proofs (fraud and validity), rollup types (classic and sovereign), ordering (centralized and decentralized), and base layers”. Of course, not all these modules will be rolled out from day one, as these things take time to build.  Stackr is a relatively new project.

What makes Intmax such an exciting project to many prominent people in the space, such as Justin Drake, is the fact that Intmax is one of, if not the only, team working on a hybrid zk-rollup/plasma solution.  **Intmax is a stateless rollup** While in general, zk-rollups do provide us with increased scalability for Ethereum, there still lies a bottleneck with data costs. In fact, over 90% of Ethereum rollup costs come from posting data to the L1.  Intmax uses a new architecture, where the end-users and node operators communicate with each other under the hood. This is what makes them stateless.  Essentially, when a user submits a transaction on Intmax, a node operator returns a “Merkle proof” of their asset. In short, a Merkle proof is a way to prove that a particular transaction is included in a block without having to provide the entire block. Using a Merkle proof, a user could calculate a “Merkle root” for a specific block and confirm that it matches the one in the block header provided by the node operator.  “Thanks to this online communication, no transaction history is required to be stored on-chain for contract execution, thus the gas cost on Intmax is reduced massively (95% cost savings over typical zkRollups!).” **Privacy by default** Because the system doesn’t have to post data on-chain, users are able to have privacy by default. We should note that while zero-knowledge proofs do provide privacy-enabling features, not all zk-rollups employ this privacy feature. Most still use zk-rollups strictly for increased scalability.  This means features like customized privacy for NFTs, potentially introducing new forms of private authentication for Ethereum users.  **What’s next** Intmax is expected to launch its alpha version on Ethereum mainnet in Q2 this year, with a full mainnet launch expected to happen sometime in Q4 2023.  One thing to note is that the team mentioned their sequencer will be decentralized from day 1 of the full mainnet launch. Specifically, the team mentioned that anyone will be able to participate and get rewarded for block mining as soon as this becomes available. Of course, benefits that come with a decentralized sequencer include censorship resistance, increased interoperability between dapps, MEV decentralization, and more.  Intmax is still a very young project.

Why is he claiming this, and is he correct? His argument [focuses on](https://twitter.com/LoganJastremski/status/1644838993903714305?s=20) two suboptimal aspects of Ethereum relative to Solana: * Lower data availability (AKA data throughput) * Lack of parallelization (AKA compute throughput) Data throughput, in a rollup context, refers to how much data can be posted to the base layer. If rollups can process a lot of data but the base layer can only handle a little data, there’s a bottleneck and fees will spike. A similar dynamic applies to compute throughput. So how does Ethereum handle compute and data throughput to keep fees down in a rollup world? Is it possible? As we know, Ethereum tackles compute throughput by offloading the work to rollups. [You can run a highly parallelized rollup on Ethereum](https://twitter.com/dankrad/status/1644976636956229634?s=20), with local fee markets to solve the compute throughput problem [just as Solana does](https://twitter.com/jon_charb/status/1644563420828631042?s=20). In fact, [you can even run a Solana rollup](https://twitter.com/dankrad/status/1645137071567192075?s=20) on Ethereum that has less overhead than L1 Solana. The extra overhead comes from L1 Solana having to pass around a bunch of messages for consensus, as L1s do. A Solana rollup, even a decentralized one, likely [wouldn’t need to pass around as many messages](https://twitter.com/dankrad/status/1645152879919996930?s=20). Of course, this only scratches the surface of what’s possible with rollups. You can innovate on the Solana rollup, for example enhancing the local fee market mechanism or [trying new mechanisms to address state contention](https://twitter.com/toghrulmaharram/status/1644950624855904257?s=20). Or you can experiment with different approaches to rollup leader election / consensus. Better yet, multiple developers can try multiple experiments in parallel. Ok, what about data throughput? This is the other piece of the puzzle, [and a separate problem to solve](https://twitter.com/jon_charb/status/1644547140981489664?s=20). [Dankrad points to](https://twitter.com/dankrad/status/1644820944488202246?s=20) the answer in his response, but we’ve also covered the topic in previous issues: * [How much can DA throughput scale?](https://modularmedia.substack.com/i/112553856/how-much-can-da-throughput-scale) * [How will base layers differentiate?](https://modularmedia.substack.com/i/111061463/how-will-base-layers-differentiate) The bottom line is that Ethereum and [other modular base layers like Celestia](https://twitter.com/musalbas/status/1638614826329972801?s=20) will treat data throughput as a governable parameter and increase hardware requirements as needed, while retaining trust-minimization and security properties. How do we reconcile Logan and Ethereum community POVs? Like many Solana ecosystem discussions, Logan’s post assumes Ethereum’s very near-term data throughput - that is Ethereum’s data throughput within the next few months. His post also assumes the execution layer being used to address compute throughput is the EVM. [There are ways to parallelize the EVM](https://twitter.com/toghrulmaharram/status/1644950624855904257?s=20), but it’s almost besides the point. There are countless ways to innovate with different execution environments and state contention mechanisms.
