Max Pick Challenge – Part 2

Today is July 15th, which marks the end of our Max Pick Challenge! A big thank you to all participants for your guesses and congratulations to our (anonymous) winner, 0x381f35f3817eee7eee571e5002db13c66e69971f, who snagged a prize of $994 paid out in ETH! We hope you enjoyed the …

Max Pick Challenge – Part 1

TACEO presents the Max Pick Challenge, a unique on-chain guessing game, based on Collaborative SNARKs ("co-SNARKs", leveraging Multi Party Computation + Zero Knowledge) with the chance to win up to $1,000. The challenge is about submitting a number between 1 and 1000. The one who…

The Encryption Trifecta

Imagine a world where your data is not only encrypted at rest (AES) and in transit (TLS) but also during computation. Welcome to the future of blockchain technology with Compute Layer Security (CLS). In this blog post, we dive into the groundbreaking vision of making encrypted co…

Unlocking the Future with ProgCrypto

At Devconnect 2023, a revolutionary concept was spotlighted during the ProgCrypto event: Programmable Cryptography. This two-day gathering of researchers, developers, and community members focused on the future of cryptography and its potential to reshape digital interactions. Vi…

Private Proof Markets using MPC

As much as we like to talk about Zero Knowledge, especially zk-friendly hash functions, we also enjoy to talk about other privacy-enhancing technologies (PETs). ZK is for sure the standout PETs performer in web3 today, with homomorphic encryption (HE) taking a little bit of spotl…

Poseidon{2} for Noir

It has been some time since our last blog post (3 months already, time flies) - so it is way overdue to continue our loose series of blog posts about zk-friendly hashing. In case you missed the other two posts, feel free to read about how to choose your zk-friendly hash function …

How to choose your ZK-friendly hash function?

In our last blog post we investigated the usefulness of hash functions for zero-knowledge use cases. Thereby, we stumbled upon many ZK-friendly designs, each with advantages, disadvantages, and optimizations for different performance metrics. With MiMC1, GMiMC2, Poseidon3, Poseid…

Bringing AI power to Ethereum with Accessible zkML

We at TACEO are thrilled to finally announce our as-of-yet largest project in the zkSpace in cooperation with =nil; foundation – a pipeline for proving ML models to L1. Why does the industry need provable ML There's no question that ML is coming into the realm of decentralized ap…

What’s the deal with hash functions in Zero Knowledge?

When exposed to the ZK space, it usually takes little time to stumble upon some alien hash functions for the average crypto engineer - most likely Poseidon1. So, for the curious, in this blog post, we want to shed some light on the history of efficient hash functions in ZK and wh…
