The Ethereum Roadmap

Talk focused on overview of Ethereum Roadmap, dives deeply into EIP-4844. Touching privacy and security principles and provides advices to hackers. My talk is pretty technicall

Free the Web

Why and how to build decentralized web sites. In this workshop I'll introduce the main technological options we have today for building on the web, mainly from a privacy perspective. After that we will build a site that can be hosted on a decentralized system with a zero need for expensive rebuilds (data are loaded on the client side using a very simple version of stale-while-revalidate pattern).

Breaking web3 bridges and burning out any web2 hacker

Talk about the state of web3 hacking, fun exploitation techniques and how web2 hackers' brains burn out when they get started with this (+ how to avoid it).

How to build a decentralised app

Technical workshop showcasing how to build a fully functional dApp in under 60 minutes.

With the recent collapses of FTX, Celsius and other centralised entities, the value of decentralisation is becoming increasingly appealing. We need decentralised apps that are as useful and usable as their centralised counterparties.

This workshop will teach you how to build a frontend web app that lets people save in savings accounts (powered by yearn.finance), all in a 100% non-custodial way. Basic front-end skills are beneficial to get the most out of this talk.

#FreeAlex Web3 activism handbook

The Tornado Cash case showed that open-source development is under attack. It's time for a Web3 activism movement to build & facilitate practical tools of direct action. Let's start with a handbook mapping down on-chain & off-chain tools for #FreeAlex campaign. Free for everyone to act now.

dm3 - Decentralized, end-2-end encrypted web3 Messaging

The aim of the talk is to introduce the dm3 protocol and show how secure communication can be integrated into a DApp with only a few lines of code.

SNARKS, ZKP, and Other Things the NSA Doesn't Want You to Know About

ZK-SNARKs have become synonymous with Web3 Privacy, but what are they? This talk will introduce ZK-SNARKs to a non-technical audience. We will explain some on-chain applications, including how the Manta Pay protocol uses them to enable private payments.

Connecting to the Nym Mixnet: Layer-0 Network Privacy for Wallets and Dapps

This workshop will cover the architecture of the Nym mixnet before focussing on the different types of Nym Clients available to developers, as well as practical examples of how developers can begin to privacy-enhance their applications by sending traffic through the mixnet.

The blind signing of contracts interaction

Users' interaction with smart contracts requires trust in several technologies: FrontEnd app, Wallet app, HW wallet, smart contract or protocol, and blockchain.

Blind signing deteriorates this trust.
