About Devcon —

Devcon is the Ethereum conference for developers, researchers, thinkers, and makers.

An intensive introduction for new Ethereum explorers, a global family reunion for those already a part of our ecosystem, and a source of energy and creativity for all.

Shaky ERC20 Allowances

Duration: 00:04:05

Speaker: Paul Razvan Berg

Type: Breakout

Expertise: Intermediate

Event: Devcon

Date: Invalid Date

Sometimes, we can't see the forest for the trees. When not used carefully in dapps, ERC20 token allowances fit that description perfectly. This presentation goes into the story of how I accidentally put over 10,000 DAI at risk for my users, even if they only deposited 100 DAI in the smart contract per se.

The CBC Casper Roadmap

The CBC Casper roadmap is a plan to implement Proof-of-Stake and Sharding for Ethereum using “correct-by-construction” (CBC) software design methodology. This talk will share new CBC Casper research, including specifications for light clients, liveness and sharding. It will include updates on formal verification and engineering efforts, and a roadmap for (eventual) release.

Dai Stablecoin

The process of developing the Dai Stablecoin System has matured significantly over the course of the last year. We innovated in the Ethereum community by being the first project to release a well-defined reference implementation, written in Haskell, for our proposed system. This effort has helped with the simplification of the system’s design, increased project efficiency, and has attracted the attention of formal verificiation specialists who now want to focus on Maker. It is becoming more and more likely that Maker will be the first non-trivial decentralized application to be formally verified before launch. In this proposed presentation, I would like to talk about the usefulness of rigorous specification and external reference implementations for the benefit of other Ethereum projects.

Why Dapp Users will Hate Cross-Shard Communication (and what you can do about it)

ETH2 is approaching, and initial indications are that substantially all dapp experiences will suffer. Some problems may be addressed with significant changes to design and development processes, but several tradeoffs are unavoidable without sacrificing scale, security, or decentralization. For example, essentially all popular dapps rely on the fungibility of Ether in a managed pool (e.g. Uniswap, Augur, Maker). In a sharded ecosystem, Ether is meaningfully non-fungible across shards, and users will bear monetary and management costs as a result.This talk will give an overview of cross-shard communication strategies and discuss their impact on developer and user experience. These include merged consensus, shard relays, consensus introspection, and credit markets. For each mechanism, we'll discuss expected impact on user experience metrics like execution time, transaction outcome, and price slippage.The talk is not all bad news. We've discovered some elegant new approaches that give dapps a variety of communication choices. The last section of the talk will discuss specific communication strategies that are amenable to specifi

Cryptoeconomics Dive: LP Volatility Harvesting Across Yield Rates

This talk furthers the concept of volatility harvesting. Currently, Uniswap and other major dexes see a huge part of their trading volume consist of the result of volatility in the market. Value changes and as a result, trading volume spikes and LPs profit. When extending yield, which is also quite a volatile concept, to AMMs, volatility harvesting is increased further to not only affect value but also the yield that value creates.
