Fuel is the fastest modular execution layer. It brings UTXO-based parallel transaction execution, a more flexible transaction format, a more efficient virtual machine, and a superior vertically-integrated developer stack to Ethereum.

From the creator of optimistic rollups, this exclusive talk will discuss how users and developers will be able to leverage Fuel for global scale, without having to sacrifice decentralization or the security of Ethereum.

https://archive.devcon.org/archive/watch/6/the-blockchain-bridge-that-you-dream-about/index

In the times where scalability of blockchains depends on multiple layers, and when interoperability holds for an essential blockchain feature, bridges become critical infrastructure parts. They are meant to hold liquidity, asked to operate quickly, but they cannot benefit from the security guarantees of an on-chain application, because they inherently contain off-chain components. In this talk, we discuss the properties of a bridge that is secure and meets all the needs for it to be useful.

It’s only been slightly over a year since Arbitrum launched as the first optimistic rollup that supported general EVM contract deployment. In that time many components have shifted, many users have migrated, and an entirely new generation of technology has shipped with Nitro. Now we look towards tackling the next set of challenges in working towards Ethereum’s rollup centric future, where using Ethereum will mean using a rollup.

Escape hatches are meant to be a way to exit assets or state from a rollup in the hopefully unlikely event that sequencers are offline. In this talk, we review which projects have these hatches and what plans are publicly available for future rollups or versions of these rollups. We list some ideas that these, and other rollups, may implement or adopt in the future, for more robust and secure rollups. The suggestions will be rooted in our concern for security and the issues presented by bridges.

Rollups are the go-to solution to scaling Ethereum and at the heart of the Ethereum roadmap. Programmable rollups and zk-evms have gathered a lot of attention and research interest. Provers in particular, which produce cryptographic proofs of evm execution, pose challenging problems both theoretically and practically. In this talk we will present our arithmetization and proving scheme, and demo the zk-evm under development at ConsenSys, providing an EVM bytecode compatible end to end solution.

https://archive.devcon.org/archive/watch/6/rollups-shards-and-fractals-the-dream-of-atomically-composable-horizontal-scaling/

Rollups allow blockchain to scale vertically, while preserving their trust properties. But what do we do when we reach the limits of vertical scalability? It might also be desirable to accomodate multiple rollups with different operating rules, virtual machines, or security trade-offs. Horizontal scaling solves these issues, but doesn't allow atomic composability. In this talk, we review approaches to horizontal scalability & ways to get as close to atomic composability as possible.

https://archive.devcon.org/archive/watch/6/using-a-hybrid-utxo-and-account-based-state-model-in-a-zk-rollup/

Many rollups choose to follow Ethereum’s account-based state model. We explore an alternative approach: a hybrid of a UTXO and an account-based model, specifically in a context of a ZK rollup. This approach offers a number of interesting properties including local transaction execution, support for privacy-preserving smart contracts, and reduced state bloat. In this talk we describe tradeoffs between different state models and cover the specific design choices we’ve made with Polygon Miden.

https://archive.devcon.org/archive/watch/6/ens-cross-chain-integration-strategy/

In general, most cross chain use cases are “asset transfer” for bridges to cross tokens from one chain to another then each application deploys the exact copy from L1 to other chains. However, ENS (Ethereum Name Service) has a set of unique challenges because ENS functions as a “global address book” to resolve addresses on any chains from any wallets. We have received lots of requests from chains and dapp developers about how to integrate ENS into their chain of choice and I am going to explain

https://archive.devcon.org/archive/watch/6/fast-and-furious-withdrawals-from-optimistic-rollups/

Bridges are very complex and have under-explored security issues. The issue we are focused on with withdrawing from L2, which requires L1 to be absolutely sure of what occurred on L2 (finality was reached) and current proposals like Offchain Lab’s Arbitrum require 1 week for finality. In this talk, we discuss the three designs for “fast” withdraws that allow a user to move Layer 2 to Layer 1 instantly, while a counter-party takes the risk that the withdraw will not finalize.

EVM is great. We love the EVM. But non-EVM based L2s bring about new paradigms, and innovations and expose us to new possibilities that are just not possible on the EVM. These L2s truly are expanding the scope of Ethereum and we should explore these more!

https://archive.devcon.org/archive/watch/6/how-bridges-improve-l2-composability/

Two of the biggest arguments against L2s are that they are breaking composability and interoperability. DApps are deployed as stand-alone apps in each L2 with limited ability to communicate with each other. This leads to silos and several issues in terms of capital efficiency, governance, security, user experience and maintenance.
We will explore how bridges should become the interoperability layer that will connect all the protocol “silos” across L2s, by using secure message passing.

Introducing the OP Stack — a standardized tech stack for L2 chains.

Introducing the Superchain vision — the inevitable unification of the distinct L2 chains into a single, horizontally scalable, super-sequenced, Superchain!

The OP Stack is how we realize the Superchain vision.

https://archive.devcon.org/archive/watch/6/ups-and-downs-onboarding-a-million-users-to-layer-2/

In the last year we’ve seen thousands of projects and billions of dollars migrate over to rollups. Liquidity and users have started aggressively migrating, but there’s still a long way to go. In this talk we’ll cover successful use cases, pain points that make it challenging for both users and developers to onboard, and emerging projects and protocols in the layer 2 space that are showing a lot of promise.

https://archive.devcon.org/archive/watch/6/a-better-mental-model-for-rollups-plasma-and-validating-bridges/

Sidechains, Plasma, Rollups, Valdiums, AnyTrust, PoS chains, Crypto Exchanges, all have one thing in common: the bridge. This talk provides an overview on the trust assumptions, threat model, security goals and solutions associated with the humble bridge smart contract. As we will see, rollups emerged because of the scalability bottlenecks faced by Ethereum, but the product-market fit is solving the operational security issues for bridging funds from Ethereum to an off-chain system.

https://archive.devcon.org/archive/watch/6/onboard-the-world-into-your-rollup-dapp-with-bls-wallet/

Bringing non-web3 native users into a dApp is always a fraught, friction filled experience, even with cheaper transaction costs on rollups. In this talk, we will show you how you can modify a dApp using BLS signatures & a smart contract wallet to:

- Embed a wallet directly in your dApp, and allow users to eject by swapping its public key.
- Bundle multiple transactions into one and submit to an aggregator to lower friction & save on gas.
- Pay for your user's transactions.

Overview of design patterns in handling ordering and execution; will cover separation of roles between sequencers and validators, tradeoffs in different ways handing execution & ordering, current approaches — i.e., what various L2 rollups are doing in production, what is and isn't possible in principle.
