In this short demo we'll look at Waku, the communication layer for Web3, and how it uses ZK for its service network. We'll demo using Waku with RLN for private, economic spam protection and what this means for you as a user and node operator. We'll also briefly look at how we can incentivize other services in the network in a private manner. Finally we'll show how you can actively participate in and contribute to the network yourself as a node operator, developer or end user.

Trading on decentralised exchanges is missing a key primitive, **privacy**. In traditional markets, an OTC desk enables large orders to trade without moving the price on chain this is missing and everyone can see everything.

ZKP's deployed in production allow us to implement private trading on Ethereum. This talk looks into:

1. How to uses ZKP's to give privacy on Ethereum
2. How to build a private dollar cost averaging smart contract using Aztec Connect
3. A code walkthrough and a demo

Semaphore is a protocol, designed to be a simple and generic privacy layer for Ethereum DApps. Using zero knowledge, Ethereum users can prove their membership of a group and send signals such as votes or endorsements without revealing their original identity. The talk will describe the protocol, the main concepts and some use cases. A simple demo will also likely be used to show how Semaphore can be used to create DApps and solve real problems in the ecosystem.

We reimplemented the Cairo VM in Rust to increase its performance. We will show an MVP that is between 10 and 100 times faster than the previous Python implementation.

Executing a program with this VM outputs a trace which can later be used to generate a Proof of the program's execution. Combining Zero Knowledge Proofs with Rollups allow us to have scalability without compromising the security of blockchains.

https://archive.devcon.org/archive/watch/6/public-private-composability/

Learn about the challenges of designing a private execution layer for Ethereum.
Previously, smart contract execution (L1 & L2) has been fully public. Some apps provide basic private functionality for a single private state (e.g. privacy coins).
We'll discuss ways to execute general private and public state changes across multiple smart contracts in one transaction, within a zk-rollup. This unlocks programmable private smart contracts.

https://archive.devcon.org/archive/watch/6/shielded-voting-using-threshold-encryption/

Shutter Governance is a tool for governance platforms to introduce shielded voting for their users. It uses threshold encryption and is designed to fix issues with misbehavior, voter apathy, and voting incentive.

Simply put, with Shutter Governance, votes are encrypted during the voting period. The votes are decrypted and thereby only revealed after the poll closes.

The talk will include a live demo of Shielded Voting as developed in partnership with Snapshot.

https://archive.devcon.org/archive/watch/6/why-we-need-threshold-fhe-for-blockchains/

There is a fundamental limit to building privacy-preserving applications in ZK. For example, we do not know how to replicate applications such as Uniswap and Aave in zero knowledge where complete privacy for users is achieved. This talk introduces how threshold FHE can help fill the gap ZK tech leave us desiring--privacy for shared-state applications.

Demonstration of how drawing from a standard cryptographic library can reduce zero knowledge circuit implementations to simple programs of as few as 3 lines.

The Join split circuit is a popular circuit that originated from Zcash and is being used in Aztec. Using the Aztec Noir standard library, we reconstruct the join split in 10 lines hiding all of the circuit complexities involved.

Recent efforts have made it possible to write zero-knowledge proofs without having deep expertise in cryptography. Nevertheless, these proofs can be subtly wrong and result in situations where the application erroneously “verifies” bogus information from an attacker. In this talk, we will give an overview of our research that can be used to reason about the correctness of zero-knowledge proofs and highlight some of the open-source tools that Veridise has developed to find bugs in ZK circuits.

Five years ago, at DevCon in Prague, EY took the wraps off Nightfall, our open source public domain approach to privacy. Now it's live on Ethereum as a layer 2 privacy-enabled ZK-optimistic roll-up solution called Polygon Nightfall. That's only half the story though - we also need private smart contracts. This talk will cover our roadmap to that end, including our newest tool in development (also open source) called Starlight.

Historically, cryptographic protocols have been built special-purpose for specific kinds of claims or information hiding mechanisms. zkSNARKs and other new cryptographic tools move us to a world of "general-purpose" cryptography, where we have expressive languages to express claims about digital identity, reputation, and more. We discuss a high-level framework for thinking about where and why ZK and related technologies might (or might not) be useful for digital applications.

The first mainstream uses of zero-knowledge(zk) proofs were for private payments in systems like Zcash and then scalability. In both, we hide data to improve privacy or validation costs. But private payments, unfortunately, have seen limited direct demand. And scalability needs faster proofs but not even zero-knowledge. What are practical zk proofs good for? This talk considers zk proofs + blockchains as a tool both for cryptocurrency and broader applications.

We'll look at Waku, the communication layer for Web3. We'll see how it uses ZKPs to incentivize and protect the Waku network. We'll also look at Zerokit, a library that makes it easier to use ZKPs in different environments.

After this talk, I hope you'll better understand the importance of privacy-protecting infrastructure and how we can build it.

In this talk, designers reflect on the common threads that run through a constellation of tools and applications built with ZKPs. We share mental models being explored and strategies for fluidly navigating an evolving space. By offering real examples from our design workshops and dApps, we will explore the question – How might we materialize abstract concepts to enable internal and external teams to build with ZKPs?

ZKPs allow transactions to prove their state transition was valid, without revealing anything about what it was. But this isn't enough, because useful applications require shared state, which ZKPs can't provide. In this talk, we'll describe how to break this barrier by combining ZKPs with flow encryption, a new threshold crypto primitive, to allow private interaction with public shared state, and how Penumbra uses this technique to build a private DEX.

https://archive.devcon.org/archive/watch/6/what-to-know-about-zero-knowledge/

Zero Knowledge, aka ZK, has become a catch-all term to represent much of "modern" or "advanced" cryptography -- especially cryptography that's relevant to the future of blockchains.

In this panel, we will share our perspectives on ZK -- how to think about it, what to look out for, and what to focus in on. We'll also discuss how ZK may alter and complement Ethereum's own future.

zkSNARKs are becoming a cornerstone of decentralised technologies. Yet they are often considered impenetrable to newcomers. We will present an update on the ZoKrates toolbox, a set of tools aimed at making developing zkSNARK applications easier using a high-level language instead of handcrafted circuits.
