Welcome to the zkWeekly edition #3! In this post, we cover the most important and exciting developments/news in the world of zero-knowledge proofs (ZKP) and fully homomorphic encryption (FHE) from the past week.
zkFHE:
A PoC to demonstrate an approach for private computation on a public environment without give up data availability powered by RiscZero.
The PoC used a tweaked version of Cupcake, creates a demonstrating protocol consists of two parties - host and guest - in which the host has the guarantee that the guest run the algorithm using zk proof and that the guest did not access to the unecrypted data with the use of FHE.
Verifiable and confidential computation based on ZKP and FHE, powered by risc0 zkVM. A PoC to demonstrate an approach for private computation on a public environment w/o give up data availability (since data can stay encrypted). FHE provides confidentiality, ZKP provides the proof that the algorithm run following the rules.
RiscZero's reflection blog on zkHack and zkSummit:
· 3 min read Instructional Design Engineer First off: huge thanks to all the organizers and participants at ZK Hack & ZK Summit! Both events were fantastic; I'm already looking forward to next time. Now that the jetlag is behind me, I wanted to share some zero-knowledge research threads that I'm excited to keep thinking about and talking about.
Ideas mentioned in this piece:
- Well-coveted folding scheme Nova along with the more generalized SuperNova and Sangria (folding scheme for PLONK)
- Red Wedding proposal from the TritonVM team to reduce verification time on a STARK system - in which the Prover can generate a SNARK proof in order to alleviate the need for the Verifier to evaluate the AIR constraints at the DEEP query point.
- Using the finite field of order 2^31 - 1 (a Mersenne prime) for building Plonky3.
HyperOracle's research blog post about zkOracle and zkWASM:
This blog post summarizes my (Hyper Oracle CTO Norman's) talk from zkDay at ETH Denver, which was originally titled "zkWASM, zkOracle and Programmability." Let's dive right in and start with the term "oracle." In the context of an oracle network, there are two types of oracles: input oracles and output oracles.
In this piece, the HyperOracle team has given their elaboration on building zkOracle Network - a type of oracle network with verifiable pre-commit computation, as well as their zkWASM, a type of zkVM that supports WASM binary - in order to generate proof for the unpredictable customized logic.
Nova (Zk proof folding schemes) for dummies
. So what is it, where is it going, and why do people like it?
ICME's founder Wyatt Benno's attempt to give a simple explanation about folding scheme like Nova, SuperNova and why these are such a big deal.
Nova's power showcasing in Zator - first end-to-end Nova based zk project
Zator is the first known end-to-end implementation with Nova - the folding scheme that has been making the noises recently. It's a verified inference of a 512-layer neural network using recursive SNARKs that has a proving time of ~50 seconds per layer on a Macbook setup.
HyperNova paper dropped:
Paper 2023/573 Abhiram Kothapalli , Carnegie Mellon University Srinath Setty , Microsoft Research Abstract This paper introduces HyperNova, a recursive argument for proving incremental computations whose steps are expressed with CCS (Setty et al. ePrint 2023), a customizable constraint system that simultaneously generalizes Plonkish, R1CS, and AIR without overheads.
There's also a companion paper that introduces CCS - generalization form of R1CS that can capture R1CS, Plonkish and AIR at the same times with 0 overhead.

The State of ZK Applications in Ethereum Part 2 from @AndyGuzmanEth:
This is the second part of a series of articles to analyze projects on the Zero-Knowledge Applications in Ethereum through a problem-lens. In the last article we started this series to analyze the landscape of applications currently built using zero-knowledge proofs in Ethereum. Today we´ll dive deeper into Privacy and Identity.

Credora - infrastructure platform for building transparent and privacy-preserving credit system for institutions utilizing zk proofs - has announed a 6 millions extra funding round with participation from S&P Global and top tier crypto VCs.
April 25, 2023 - New York, US; The crypto lending business model has come under intense scrutiny following a spate of recent credit events. Credora is helping rebuild confidence in credit markets through transparency, and today the lending infrastructure provider announced a $6m strategic funding round with S&P Global and Coinbase Ventures as major investors.
Blockless - a serverless function platform that utilizing zk proofs to prove the execution of the functions - has been selected as one of the 4 projects on the debut cohort of Poolside's Web3 accelerator
With over 300 applications and countless interviews, we've handpicked four projects that stood out by their idea, team and market potential. We're thrilled to announce that our program is springing into action this week, and we're excited to help those projects grow during the next 12 weeks!
We are thrilled to introduce you to Blockless, one of four groundbreaking Web3 startups joining the Poolside Accelerator program. Blockless offers zk verifiable serverless functions for building fast and limitless decentralized serverless applications. Led by founder Butian Li, who has years of experience in the blockchain industry and has successfully led Web3 projects listed on Binance, Blockless is poised to revolutionize decentralized application development.
