Taceo and the Aztec Foundation work together to create a private shared state, a cryptographic environment that supports updates, multi-computing and auditing under one private, distributed roof.
summary
- Taceo and the Aztec Foundation are partnering to bring private, shared states to Ethereum.
- PSS differs from existing MPC solutions by allowing on-chain shared and sustainable private land, focusing on developer usability through Taceo’s Conoir Toolkit.
- Taceo argues that the system is built with post-Quantum security in mind, exploring hash-based proof systems using theoretically secure protocols of information.
The company behind Worldcoin’s encrypted Iris Scan network and the largest known multi-party computational database, Taceo is partnering with the AZTEC Foundation, a nonprofit supporting the AZTEC network to create a private shared state at Ethereum.
Partnerships argue that they allow multiple parties to validate blockchain transactions and contracts without publishing the underlying information or relying on centralized entities to validate them. It combines Taceo’s collaborative computing power with Aztec’s Privacy First Layer 2 Ethereum (ETH).
Taceo CEO Lukas Helminger tells Crypto.news that it will help extend multiparty calculation or MPC capabilities to new areas where PSS was previously limited. This system allows multiple users to collaborate on encrypted datasets.
“Simply put, the PSS allows multiple parties to jointly maintain and calculate one shared civil state, and commits that state with publicly verifiable proof,” Helminger said.

Through collaboration, AZTEC developers can use enhanced tools that support complex, collaborative computing. Developers can perform generic calculations on encrypted data from a variety of sources, generating functionality and privacy beyond what Web2 can do.
PSS is poised to promote a variety of use cases, including unreliable financial markets, joint AI model training, cheatproof-on-chain games, and data sovereignty frameworks.
I don’t have a CEO: “Our approach is different.”
Taceo CEO Lukas Helminger explains how private shared states differ from Mill-of-of-Mill multi-party calculation solutions to enable arbitrary calculations on encrypted data.
According to Helminger, this approach creates “a permanent state in which a single entity is inaccessible but can be updated over time,” allowing multiple parties to jointly maintain and calculate the same civilian state. This sets the PSS apart from ZKMPC. He said this focuses on one-time, safe calculations without providing a chain state model that contracts can refer to.
The company also distinguishes its work from Nucipher’s threshold encryption framework.
Nucipher focuses on traditional use cases of MPC or threshold encryption to allow signing, decryption delegation and access to thresholds, but PSS goes beyond that by providing shared, updatable private states with on-chain proofs.
Another major difference that sets PSS apart from other solutions is its focus on ease of use for developers.

“Our approach is different. We’re shaped into tools that developers can pick up to build sensitive apps,” says Helminger.
Through the Conoir Toolkit, the company hopes to make integration seamless for those using Noir, Aztec’s zero-knowledge programming language.
“Traditional MPC libraries often came out of academia, meaning they were powerful yet not practical. At Conoir, we aim to do the trivial things to extend applications to MPC and PSS environments already using Conoir,” says Helminger.
From a safety and security perspective, Helminger has experienced years of peer-reviewed research on the protocols on which the network is being built, and currently undergoes security assessments, with regular external audits planned when the system is stable.
“Due to the nature of MPCs, a single node will not learn plain text and will remain confidential unless the threshold of the conspiring node is exceeded,” he said.
How are private shared state fares for Quantum Computing done?
Many experts see quantum computing as a potential threat to rapidly evolving cryptocurrencies. In fact, many people predict that with enough power, they will one day break Bitcoin encryption and access the wallet, an event called “Q Day.”
More recently, Solana co-founder Anatoly Yakovenko said there is a 50-50 possibility that it is strong enough to crack the crypto safeguard protecting Bitcoin wallets five years later.
When asked how Taceo and Aztec’s PSS oppose the threat of quantum computing, Taceo CEO Lukas Helminger said that some of the stack, including secret sharing within the MPC environment, is “already informationally safe and naturally after Quantum.”
“Certain proof systems have quantum risks, including actively investigating post-Quantum safe approaches, including hash-based ZKs,” Helminger said.
He explained that the research team working on the project has experience working on post-Quantum standards, so as the technology continues to evolve, they prepare the system with a clear transition path in mind.
“We’re taking a cryptographic agile approach. The system is designed to allow components to migrate to the rear alternatives as they mature and mature. For example, if today’s sense of smell relies on the assumption of an oval curve, we’re already experimenting with hash-based proof systems,” he said.
