Agenda

The blockchain space is undergoing a rapid push to connect isolated ecosystems and give users the ability to interact with multiple blockchains at once. Bridges are popping up left and right, but this first wave of interoperability solutions are often narrowly focused on moving tokens from chain A to chain B and vice versa. Allowing liquidity to flow throughout the blockchain space is a major first step, but solutions that enable developers to launch applications that run seamlessly across multiple blockchains will give users far richer cross-chain experiences. This is the frontier for blockchain interoperability.

Our progress on building trustless bridges in the PoS Ethereum cross-chain environment

The Ethereum 2.0 spec introduces the sync committee protocol, allowing for a lightweight light client implementation. We build a gas-efficient EVM light client by moving expensive computation, such as verifying validator signatures, off-chain using zkSNARKs. This requires implementing out-of-field arithmetic for the BLS12-381 curve. Our light client allows for arbitrary state proofs and message passing between two chains that implement Eth2 consensus. As an example, we showcase a prototype ERC-20 bridge from Ethereum to Gnosis Chain, which borrows the security guarantees of the sync committee.

I will explain the major improvements we came up with while building the zkEVM. This will include some tricks in the state machine design and some insides in the prooving system, including small prime recursive STARKs and verifying STARK with a groth16/PLONK. I will also do a live demo of the zkEVM testnet.

Alex Gluchowski, co-founder of Ethereum scaling platform zkSync, will offer a look at the importance of zkRollups, the difference between EVM equivalency and EVM compatibility, and the current deployment state amongst zkRollup options.

There are multiple ways for DAOs to set up governance for their communities. Some prominent ones are Compound-style governance contracts, Aragon, and our favorite, the Gnosis Safe. This talk reviews several popular governance frameworks available today and explains why SZNS uses Gnosis.

The tragedy of the commons is a problem in economics that occurs when individuals neglect the well-being of society in the pursuit of personal gain. In game theory, the tragedy of the commons is seen as a Nash equilibrium, where no rational agent cooperates despite it being the strategy that would maximize collective payoff if adopted by all players. Protocols are sets of rules and guidelines for communicating data. On-chain governance systems, on decentralized distributed ledgers, can serve as censorship-resistant protocols enabling communities to gain autonomy and also coordinate trustlessly, thus collectively owning, developing and governing public goods that benefit everyone and harm no one.

When the frameworks, processes, and structures are not set up at the birth of a DAO and left up to chance, things can go sideways.Things I learned by trying to shape MakerDAO's Governance.

One of the biggest problems with DAO governance today is that most of it is token-based, which leads to capture-risk; meanwhile, problems with sybil-resistance hamper exploration of more equitable governance models. With contribution management tools such as Govrn, what if contribution-based governance can improve how DAOs operate today?

A guide through the key points to connect an existing Dapp to the Safe or create your own new Safe App. Target group: All level developers that want to learn how to connect a Dapp interface with the Safe or to create their own. Tools: A basic node.js development environment, laptop, text editor, terminal, git, node, yarn. Browser with Metamask.

In this workshop, we’ll introduce Moonbeam, a smart contract platform for building cross-chain connected applications that can access users, assets, and services on any chain. Then we’ll dive into the hands-on components of building connected cross-chain applications. First, we’ll show how you can call a contract on any supported chain from Moonbeam with Axelar’s general message passing. Then, we’ll explore how Moonbeam’s variety of XCM integrations enable native interoperability within the Polkadot ecosystem. In addition to cross-chain asset transfers, we’ll demonstrate remote execution with XCM.

Developing L2 applications for Starknet with OpenZeppelin Contracts and Nile Target group: Developers interested in L2 development Tools: Ideally they would install the Cairo language. Apple M1 users may need to have a linux subsystem like docker in case they encounter issues.
