On top of that, our grant committee will be providing advice and feedback on the proposals you will be submitting so you will be well positioned to win a hackathon prize AND additional funding that will carry the project to the 6-month mark post hackathon.


✍️ Rethinking Ethereum consensus with Beam Chain 👉Read(EN)
Ethereum researcher Justin Drake introduced a proposal to overhaul Ethereum’s consensus layer, called the “Beam Chain.” This redesign, pitched to a packed house at Devcon Bangkok, aims to modernize a part of Ethereum’s core infrastructure while maintaining compatibility and decentralization. The idea is to accelerate parts of the Ethereum roadmap to take advantage of cryptographic advancements, address inefficiencies and clear out existing technical debt incurred since the 5-year-old design of the Beacon Chain, Ethereum’s current consensus layer.
✍️ From prediction markets to info finance 👉Read(EN)
In a recent post, Vitalik Buterin reiterated many of the points we’ve discussed about the efficacy of permissionless capital formation, highlighting Polymarket as part of a major shift in how people access timely, accurate information. Prediction markets are often dismissed as mere gambling, yet they hold significant value for forecasting and decision-making across sectors like social media and scientific research. Polymarket, for instance, demonstrated this potential during the U.S. election by quickly adjusting odds based on real-time data, predicting Trump’s win long before mainstream media (image above). This mechanism isn’t just about betting; it’s about gathering decentralized, unbiased data that adapts dynamically to emerging information, providing a much-needed alternative to centralized narratives.
✍️ What are we looking for when chain abstracting? 👉Read(EN)
The fan-in / fan-out across chains matters when thinking of really good solutions. Maybe the answer is ‘everything’, and that’s OK, but looking to understand better user patterns/expectations. From a dev perspective, for the people building intent-based systems, do you expect devs to be willing to integrate with the intent standard, or do most people use msg.sender to auth, and that’s a problem?

💸 Rai Bug Bounty
Maximum Bounty $100,000 👉 Apply
RAI is an ETH backed stable asset with a managed float regime. The RAI/USD exchange rate is determined by supply and demand while the protocol that issues RAI tries to stabilize its price by constantly de or revaluing it.
