Introducing Scroll's Bernoulli Upgrade 🚀

Our latest protocol enhancement includes added support for EIP-4844, decreasing the cost of @Scroll_ZKP transactions by up to 10x.

scroll.io/blog/blobs-are… Ethereum's most recent upgrade, Dencun, introduced the eagerly anticipated EIP-4844, a feature designed to reduce the cost of posting rollup data to the Ethereum network.

It's time for our end of week update, where we provide an overview of everything that's been happening across the
@Scroll_ZKP ecosystem.

Let's dive into this week's news 👇 For anyone heading to @EthereumDenver, we published our full itinerary so that you know where to find us at anytime throughout the event ⛰️🦬

As always, we'll be participating in numerous presentations, panel discussions, and workshops!

Calling all Creators, Creatives, and Collaborators 🎨

Collaboration is important to us, and we are extending an invitation to our community to join us in shaping Scroll’s visual identity.

Join us for a chance to have your creation embedded in Scroll's identity! For our first contest, you are tasked with designing one or more characters that represent and embody Scroll's values and brand image.

You have the freedom to create, experiment, and collaborate on different styles and designs that represent your vision of Scroll's identity.

It's been an exciting week, and once again, we are back with another weekly update to get you up to speed with everything that's been happening across the Scroll ecosystem.

Let's dive in 🧵 First up, we celebrated the launch of our Sepolia testnet, our final phase of testing before we deploy Scroll on Ethereum mainnet.

For an in-depth overview of what's included, we published a blog post that outlines all of our latest feature improvements.

gm Scrollers, we have some exciting news to share today!

We are pleased to announce that @AaveAave, one of the leading foundational pillars in DeFi is now live on our Alpha testnet!

Dive in to learn how you can get started using Aave on Scroll.

📜 🤝 👻 Since 2017, @AaveAave has been a force for good in pioneering the DeFi space while continuing to innovate and push the boundaries of what's possible on Ethereum.

Aave's strong commitment to decentralization goes hand-in-hand with our core values.

We've been busy!

It's the end of the week, so here's the weekly recap: This week has been full of stress testing. Scroll Alpha has been settling ~300,000 transactions per day!

We pushed a lot of stability improvements to our Alpha testnet this week to support the higher load.

ETHDenver was a blast! We had 55 fantastic submissions compete for $16,000 in bounties.

Here are the winners: Our "Applied ZK, with a side of Scroll" category was for dApps that leveraged ZK in interesting ways.

We had two winners, grabbing $1500 each:

An update: To accelerate plans for developing our zkEVM, pursue cutting-edge research, and continue building with a broader community, we've raised capital from a global set of participants. We are humbled to have had substantial interest in our progress. Scroll is, and always will be, a scaling solution and ecosystem built for the global Ethereum community.

For nearly two years, we've built our zkEVM in the open alongside @PrivacyScaling and other contributors, and today, we're taking the next step to Goerli, the final stage before mainnet.

Our testnet on Goerli is 100% permissionless.

Here are the details: ZK is an essential component for the future of blockchains.

Just a few years ago, zkEVMs were entirely theoretical, but an incredibly talented community of researchers and builders have combined efforts to make it a reality.

It's that time of the week again!

Here's the weekly update: We're at @EthereumDenver! If you want to find out what we're up to, we've compiled a handy page with the details: ethdenver.scroll.systems

This will be frequently updated with hackathon details, links to Scroll-related talks, and info on various side events we're a part of!

The end of the week calls for another weekly update 📰

Let's dive in: We're hard at work laying the foundations for our next testnet on Goerli. Our Alpha Testnet is on the way!

We've set up new multi-VM infrastructure, rolled out an improved load balancer, and continue to work on stability improvements.

For nearly two years, we've been heads-down building a bytecode-compatible zkEVM in public.

Today, we're increasing that transparency even further by introducing regular weekly updates.

Here's what we were up to this week: Systems are being set up and prepped for future deployment on Goerli. More details Soon™

We've also made progress on an improved v2 bridge design which should result in a smoother experience!

Our most recent testnet upgrade included a huge performance boost: batching.

Here's how it works: Previously, our testnet generated a proof individually for every L2 block, regardless of the number of transactions within it.

With our new batching system, instead of proving blocks individually, blocks are now aggregated into batches.

Our scheduled testnet reset has been carried out successfully 🛠

Users and developers can now interact and deploy smart contracts onto the updated version of our Pre-Alpha!

See below for instructions 👇 In order to interact with the updated version of our Pre-Alpha, users will need to perform an account reset (MetaMask or BlockWallet) for both the Scroll L1 and the Scroll L2 network.

The @ethereum KZG Summoning Ceremony is here, and we need your help!

Here's a quick explainer + how to contribute: Ethereum's EIP-4844 upgrade will create a new type of data storage for rollups that is more scalable than simply storing it in CALLDATA.

This results in greater scaling and cheaper rollup fees!

gm 2023

Here's what Scroll did in 2022: The Pre-Alpha testnet went live in August. Some stats:

- 397k+ unique addresses
- 6300+ unique contracts deployed
- 600+ unique tokens deployed

Average daily transaction volume: ~32k

Try it out for yourself at prealpha.scroll.io

On January 9th, our team will be performing a scheduled Pre-Alpha reset in order to roll out some new and exciting performance optimizations that will help drive a higher throughput in our Pre-Alpha testnet!

Details in the 🧵 1/ The following URLs are now the new RPC endpoints that users will need to use to interact with our updated Pre-Alpha testnet.

- prealpha-rpc.scroll.io/l2

Today's zero-knowledge proofs have a big bottleneck: proof generation is slow and expensive.

Why is proof generation slow and expensive? Can it be accelerated?

Learn all about proof generation in our new technical blog post:

scroll.io/blog/proofGene… 1/ Zero-knowledge proofs are often used to prove that some program was executed correctly.

Generating such a proof generally requires many orders of magnitude more computation than the original program execution.

Polynomial commitment schemes are critical to Ethereum’s scaling solutions.

These schemes will be used in Danksharding, as well as in the proof systems behind Scroll. What are polynomial commitment schemes? And how will they help scale Ethereum?

scroll.io/blog/kzg 1/ A polynomial commitment scheme is a scheme in which a party can commit to a polynomial p(x), and can then prove its evaluation at any arbitrary point. Evaluations can be verified using only the commitment and the proof - the polynomial itself need not be revealed.

We are thrilled to release an upgraded version of the Scroll Pre-Alpha Testnet! scroll.mirror.xyz/FYzq9QWb2UhS00… 📜 The upgraded Pre-Alpha Testnet will be the first chance for early developers to experience contract deployment on Scroll and to interact with our infrastructure. 🧵👇

We are pleased to finally announce our list of incredible speakers that will be joining us for our upcoming Rollup Day! 📜

Let's take a look at our programme full of panels and presentations focusing on the Rollup-Centric future of Ethereum

🧵👇 1/ For those of you who would like to participate remotely, we will be livestreaming the entire event (link to come).

Big shout out to our speakers and friends who made this possible! @VitalikButerin @Justindr @dankrad
