Panel discussion on the Swiss Blockchain Ecosystem

Web3 Functions are a new paradigm enabling developers to build web3 apps that run entirely serverless without creating a single point of failure and trusting a centralized party to run the correct computation.

People are just as important as tech in this space. Sometimes this is underestimated, especially when we just focus on finding some new use cases to get out of the bear market. But building does not just involve the tech, people and strong communities are just as important!

Ethereum has been one of the first peer-to-peer decentralized platforms to allow for the execution of smart contracts. These are contracts which are implemented automatically, hence do not need a third party for their enforcement. Users wishing to execute smart contracts on Ether

DeFi's automated protocols conflict with traditional finance's need for regulation & depositor protection. Risk management measures can bridge this gap, including reporting tools & decentralized governance. Benefits include investor confidence and broader adoption.

How can we ensure financial privacy on-chain in compliance with AML laws?

The talk will present a 2022 retrospective on on-chain paid user fees in various protocols and dapps.

Many projects are vulnerable due to an inadequate testing suite, and most vulnerabilities are in cross-chain scenarios because developers have not been able to test them properly. Let's change it!

We consider algorithms for transaction ordering that takes into account both transaction timestamps and bids. The algorithm guarantees that users get their transactions published with bounded delay against a fee, while it extracts a fair value from sophisticated users.

As protocols evolve, a growing need of adaptation appears. How can decentralized protocols adapt to context without a main driving force?

Let’s play 2 truths & 1 lie, you might be surprised by the answer—FHE is slow, FHE is unusable, FHE is useless. While privacy has become crucial for web3, what once was the holy grail of cryptography supporting private computation has fallen by the wayside. Why is that?

The DAO ecosystems keep growing and the tools needed by the communities are increasing too. Let's dive into the most used DAO tools (based on on-chain data) filtered by the following verticals (Governance, Payroll, Operations, Retribution)

Proto-danksharding (aka EIP-4844) is a planned change to the Ethereum protocol which introduces ephemeral data storage.
