Zcash + Ethereum = ❤
This presentation focuses on how Zcash uses zero-knowledge proofs to add private transactions to a public blockchain, and how Zcash and Ethereum will grow together. Zcash is a new cryptocurrency that provides private transactions — the sender’s and receiver’s addresses are not publicly visible in the blockchain, nor is the amount transferred. Zcash posts that private information to the blockchain in encrypted form, and uses zero-knowledge proofs to cryptographically guarantee the validity of transactions without exposing the private information. This results in “Selective Transparency”. It’s not all-dark-all-the-time — it’s that each encrypted transaction in the blockchain can be revealed by its creator to selected third parties. Zcash is developed by a VC-funded, highly skilled development team and a widespread and active open source community. There are three paths forward for integrating Ethereum’s programmability with Zcash’s privacy. The Zcash team is actively contributing to all three paths. 1. Programmable Zcash — add Ethereum-style programmability to the Zcash blockchain 2. Private Ethereum — add Zcash-style privacy to the Ethereum blockchain 3. Project Alchemy — interoperation between the Ethereum and Zcash

Keynote: Lessons learned from Tor
I will share lessons learned during Tor's twenty years as free software fighting for privacy and human rights. We'll talk about distributed trust and privacy by design, how to help people understand the good uses of your tech, getting allies in both cypherpunks and government, why transparency and community-building are so essential to trust, and successes from other spaces. It may seem like the crypto wars never really end, but we all have a part to play in saving the world.

Keynote: Glass Houses and Tornados
The Tornado Cash sanctions and criminal prosecutions have challenged longstanding assumptions within crypto about the limits of money transmission licensing, money laundering statutes, and sanctions laws. They've also revealed a longstanding assumption from some in policy and law enforcement circles: that blockchains have always been and must remain transparent. Neither assumption has served us well and the time has come for legal certainty. This talk is about how we get there.

Tending the Infinite Garden: Organizational Culture in the Ethereum Ecosystem
This presentation will discuss the findings of the academic paper "Tending the Infinite Garden: Organisational Culture in the Ethereum Ecosystem" by Dr. Paul-Dylan-Ennis and Ann Brody. Our study examines the decision-making processes fundamental to Ethereum's protocol governance, drawing on interviews with Ethereum's core developers. We identify a central worldview in Ethereum known as the "Infinite Garden" and discuss how Ethereum's social layer is crucial for upholding cypherpunk values.

Keynote: Make Ethereum Cypherpunk Again: Why we need privacy
The Web3 revolution seeks to address the sins of Web2. However, in doing so, it’s created an even worse outcome for users - users’ data is publicly available and makes them vulnerable to state-level censorship and adverse actions. This talk will address the philosophical as well as practical considerations of privacy in Web3. Privacy is an industry-wide issue and sits at the heart of all that is Web3. Understanding why privacy matters involves recognizing that it is not an isolated concept bu

Keynote: How to Properly Open Source Software: Lessons Learned from the Linux Foundation
It can be challenging to properly open source software: there are licenses, IP, security reporting, and many other issues that need to be addressed. In this talk, we will discuss the best practices for open source software development learned from almost 25 years of experience at the Linux Foundation. Attendees will learn about how to set up their projects for a variety of potential goals, including things like maximizing security and community building.

New hash functions for Ethereum, SNARKs, and STARKs
Traditional cryptographic hash functions such as SHA-256 are well known in the Ethereum community and are well regarded for security and performance. However, they are not quite suited for SNARKs and STARKs as their circuits are too complex and slow in SNARK/STARK-friendly fields. That's why Zcash proofs originally took more than 40 seconds to create. In this talk we present and call for new designs that will make all the SNARK/STARK crypto much faster and thus bring better privacyto Ethereum. In particular, we cover: -Existing algebraic hash functions such as MIMC. -Merkle tree enhancements: wide functions and trees with feedback; -improved algebraic function design using ideas from AES and SASAS schemes. -performance overview; -how new designs will affect EVM and smart contract programming. We will also present other directions and potential research bounties that can be offered to motivate the hash research, crucial for SNARKs, STARKs, and Ethereum.

P4: Private Periodic Payments Protocol
P4 aims to solve the problem of subscription services offering end-to-end private cryptocurrency payments. This protocol introduces periodicity to cryptocurrency payments through an ongoing relationship between the merchant and the customer without unintentionally disclosing personally identifiable information. We are creating this protocol to allow us to offer a truely end-to-end private subscription data storage solution built with Tahoe-LAFS. By sharing it, we hope that other subscription services will implement our protocol and further the adoption of cryptocurrency payments in real world retail use cases. Although this protocol is currently a work in progress, we have already specified some design decisions. For periodicity, we are avoiding a payment pre-authorization design to keep the user in control of their keys. And for privacy we are utilizing Zcash shielded transactions and the coming improvements in the Sapling release. This protocol is being created by the Least Authority team with support from the Zcash team.

The State of Whisper
Whisper is the Ethereum Foundation's secure communications protocol. It has been designed to ensure darkness, i.e. guarantee that neither a message's content nor its metadata can be captured by an attacker. With the release of version 6 last spring, it is now also used to prototype the switch of the P2P stack from DevP2P to libp2p. This talk will start with a summary of the protocol, followed by in-depth coverage of two upcoming features that will improve its usability: 1) insights into the libp2p switch, and 2) compiling it to WASM to run directly inside a browser, thus bypassing the confusing RPC interface.
