My talk will focus on regenerative finance’s (ReFi) first building block: tokenized carbon credits. As a new planet-positive primitive, tokenized carbon credits can be integrated into dApps on Ethereum and the wider web3 ecosystem, enabling developers to encode climate-positive actions into their products. Ultimately, a DeFi economy that incorporates carbon credits will be our chance at turning the global economy from one that is extractive to one that is regenerative.
Humanity faces a crisis of innovation. Our best academic and scientific minds are forced to operate in a century old system. The DeSci movement aims to put power back into the hands of people and enable self-sovereign science. Today, biotech DAOs like VitaDAO, LabDAO or PsyDAO are redefining how research is done and IP democratised through permissionless data and legal protocols like Molecule. Over the past year, multiple research projects at universities and laboratories were funded directly through web3 communities of scientists, patients and geeks. This talk will explore the DeSci movement ethos and vision, the problems in modern academia and the biotech industry, and how web3 could fundamentally fix these. We will deep dive into the technical architecture of an IP-NFT as a composable asset, as well as the governance and organisational frameworks that these DAOs and their members are using to own and develop real-world IP.
Wallets have made great strides since the beginning of Ethereum. Kristof will recount how they started, the radical innovations that have emerged since then, and most importantly, what might still missing from them to achieve mass user adoption.
Sourcify is an open-sourced contract source code verification tool and maintains a public repository of verified contracts on IPFS. It makes use of Solidity's contract metadata and the metadata hash appended to the bytecode to "fully verify" contracts. The talk would cover how the source code verification work, how Sourcify's verification differs from others, and how we can achieve more human-friendly contract interactions with NatSpec documentation and contract metadata.
Ethereum provides decentralized, permissionless and censorship-resistant state settlement and dApps make extensive use of that. However most dApps also need counter-party discovery and solving capabilities in order to provide users with interactivity to discover others with whom to trade/settle transactions. This talk proposes an intent-solver pattern and explains how dApps from OpenSea to CowSwap and L2s such as Optimism or Starknet can use it to become truly decentralized.
Smart contract transactions are opaque - making debugging difficult and opening up your dapps to vulnerabilities. In this talk, we'll dive into how you can incorporate Truffle into your existing tooling stack to decode, debug, and secure your transactions to find out WTF is really going on.
In this session, you’ll hear from Infura’s co-founder, EG Galano, about the history of Web3 infrastructure and the roadmap for developers, creators, and users in a multi-chain Web3 world. Be among the first to hear about Infura’s long-term vision and strategy for the next chapter in the Web3 revolution.
Solidity is far from being finished. We are constantly evolving it to make it easier to write safe dapps. In this talk I want to present some of the more recent features and a glimpse into the future. Get ready to hear about custom datatypes, generics and improved memory management.
Building front-end for DApps that touches many layers or chains introduces extra levels of complexity to already non-trivial blockchain development. Join us and learn how to rapidly develop front-ends for your smart contracts working on multiple chains. Make the user experience snappy, while keeping your Infura/Alchemy bill. Learn about good practices and pitfalls.
