BuidlGuidl - Build Your first five apps on Ethereum

**Afternoon Workshop (1:15 - 2:15 pm)** Accelerate your Ethereum skills in this rapid-fire workshop! You’ll build five dApp prototypes on Ethereum using Scaffold-ETH 2 and its powerful extension starter kits We’ll cover key concepts in smart contracts, front-end dApp development, and how Scaffold-ETH 2 streamlines the process with ready to use state-of-the-art tools. This session is ideal for beginners looking to gain hands-on experience quickly.

BuidlGuidl CTF - Capture the Flag game

**Capture the Flag for Ethereum Developers (2:30 - 5:30 pm)** Show off your Solidity skills in BuidlGuidl's CTF! Tackle 10+ challenges across all skill levels (beginner to advanced), and race to grab the most flags for a chance to win ETH, swag, and fully synced ETH nodes! Open to all skill levels — join the fun! (solo or teaming up with frens)

Austin Griffith – Intro to Scaffold-ETH 2 and SpeedRunEthereum!

In this session, we’re going to dive into Scaffold-ETH v2, a toolkit we built to make developing on Ethereum way easier. We’ll take a look at how it works, why it’s super useful for quickly spinning up projects, and how we can use it to tinker with smart contracts and hook up the frontend. ⚙️ Scaffold-ETH 2 is built using NextJS, RainbowKit, Foundry/Hardhat, Wagmi, Viem, and Typescript. Whether you’re new or experienced, we’ll get you to SpeedRunEthereum!

Build and deploy an onchain app in 80 minutes!

We will tinker with Solidity, build out a frontend, deploy the contract, and ship an app onchain—all in 80 minutes with state-of-the-art tooling.

Recurring meta transactions to power l33t subscriptions!

Dapps require way too much on-boarding. The Ethereum ecosystem needs to push toward mass adoption by allowing new users immediate access to functionality and interactivity without all the hoops to jump through. This means paying the gas for first time users' transactions.  Thanks to public/private key pairs, users can sign meta transactions and incentivize desktop miners to pay the gas for them. I will demonstrate how etherless accounts can craft and sign transaction off-chain and send them to a relayer. The relayer, incentivized by the a reward in the transaction, submit the the meta transaction to a bouncer proxy and pay the gas.  This also works great for Universal Logins where you have an identity proxy that your etherless devices can transact through.

Building Consumer Apps with Programmable Cryptography

0xPARC community developers will present apps built on top of the Programmable Cryptography stack, including FROGCRYPTO, Zupass, Meerkat, and many more. This session will also include a live workshop where you can learn to build your own, and there may be a cryptographic prize for those who complete the challenges…

Keynote: Programmable Cryptography and Ethereum

Programmable Cryptography is a "second generation" of cryptographic primitives - primitives that allow arbitrary programs to be executed "inside of" or "on top of" cryptographic objects. Programmable cryptography provides three key affordances that complement and amplify the affordances of Ethereum--verifiability, confidentiality, and non-interactivity. We'll discuss how these technologies can reshape the Internet over the next 50 years.

[CLS] Ethereum Magicians Infinite Endgames: Ethconomics

Once again, Devcon will host Ethereum Magicians gatherings for the community to come together and discuss the most important topics in Ethereum's roadmap. Join us here to discuss the "infinite endgame" for Ethereum's economic model. We'll cover the role of Ether in the network's security, issuance proposals, out-of-protocol economic influences, and more! For more context, see: https://bit.ly/ethmag-sea

The Shape of Protocols to Come

Ethereum defies easy categorization—it blends aspects of money, nations, and more, yet doesn't fit neatly into any single category. To build better mental models for understanding Ethereum, we've spent the past two years stepping back and exploring the broader class it belongs to: Protocols. This talk explores the fundamental properties of protocols, strategies for navigating them, and how Ethereum can uniquely contribute to this emerging research field.

Lunarpunk Endgame

Global surveillance is a static world where change is surpressed and society cannot evolve. In contrast, an anonymity-enhanced world resembles a forest. New civilizational experiments blossom like flowers, radiating outward from the freedom-fighters of the future. The lunarpunk end game is to enable a new ecology of social orders. This talk will describe the grand vision of lunarpunk: multipolar space-faring civilization, human speciation, and the reproduction life throughout the cosmos.
