1 Human 1 Vote Money Legos 🔜 More Democratic DAOs 🧱🤝✨
Right now, the DAO ecosystem is built around one-token-one-vote or one-cpu-one-vote schemes. With strong sybil resistence, the ecosystem could move to DAOs built on one-human-one-vote. This unlocks more democratic use cases like: - quadratic funding - quadratic voting - Gini coefficient measurements - UBI - one-person-one-vote DAOs - data collectives - sybil resistant airdrops + more Learn about the current landscape of sybil resistance techniques in web3.
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.
A journey to the center of the eth: How the Gas Station Network improves the UX in Ethereum
The Ethereum developer ecosystem is in constant change. Undoubtedly, teams have started to leave the development of Smart Contracts in the background to focus on the development of decentralized applications, and on how to eliminate friction points between users that might not know anything about Blockchain but still need to interact with it. But developer tools are still important and they have to be simple and secure to use. In this talk we will explore how the Gas Station Network is implemented to redefine the interaction between users and DApps in a way that they don't need to have any knowledge on mnemonics, private keys, transactions or gas costs. Moreover, we will go through a set of tools that the OpenZeppelin team developed to make this transition from regular DApps to gasless DApps in a super easy and fast way.

A trustless Ethereum mixer using zero-knowledge signalling
Since Ethereum transactions are fully visible on-chain, it is possible to trace value transfers and surveil users' financial activity. This state of affairs deprives users of privacy beyond mere pseudonymity. Some workarounds, like using a centralised exchange wallet or a custodial mixing service, however, introduce a high degree of counterparty risk. The Ethereum ecosystem needs a noncustodial mixer which works through strong cryptography, rather than blind trust. To solve this, we present a trustless mixer for Ether and ERC20 tokens. It builds upon Semaphore, a zero-knowledge signalling system by Barry WhiteHat and Kobi Gurkan. Additionally, it employs a burn relay registry which incentivises third parties to pay gas fees on behalf of mixer users. In this presentation, I will show a high-level architectural overview of the mixer, dive into its underlying zero-knowledge circuits, and discuss other applications of zero-knowledge signalling.

A Conservative Approach to a Radical Roadmap
The current Ethereum 2.0 roadmap is doing a lot of great work on many fronts such as research on VDFs, data availability proofs, and multi-execution environments. However, as an active observer of the Ethereum 2.0 roadmap development over the past 2 years, I am concerned with some of the choices in roadmap strategy, particularly its approach to radically transforming a network with over $30B of value and hundreds of applications depending on it. In this talk, I will present an alternative, more conservative view of how to approach the Ethereum 2.0 roadmap. Some of the topics covered will include: - Radical vs Conservative technological upgrade paths. - We should use Ethereum 1.x as the beacon chain instead of launching a new beacon chain. - Proof of Stake is highly experimental. We should test Proof of Stake on shards before using it on the beacon chain. - Why requiring a 1-way peg burn of ETH to stake is scary. - Learnings from 3 months of Proof of Stake on Cosmos - Why we NEED delegation *in-protocol* - Why sharding doesn't solve social scalability.
A Visual Overview of Blockchain Development
“The open-source model is a decentralized software development model that encourages open collaboration. Depending on the license terms, others may then download, modify, and publish their version (fork) back to the community.”Yet the ‘open source way’ doesn’t always abide by the rules and many developers just don’t care enough to choose the right license. Arguably, the more than 80 license types scare developers away. This talk will show us the current state of licenses out in the wild west of open source Ethereum communities- for that, we’ll look at charts, diagrams and maybe even maps- and help you choose an appropriate one when starting a new project.

(Devcon Week: Oct 7 - Oct 16, 2022)
Devcon VI brought the Ethereum ecosystem to South America, to Bogotá, Colombia. Devcon keeps growing, and with over 6,000 attendees and contributors, around 350 speakers, and 9 talk rooms, it was the biggest Devcon yet. Rumors has it that it was also the best Devcon ever.
