Postquant Labs launches first quantum cross-chain exchange

Postquant Labs announced the launch of QuipSwap, a bridgeless protocol for secure cross-chain asset exchanges

Summary

Postquant Labs is about to launch QuipSwap, a bridgeless protocol designed to minimize trust across chain exchanges without intermediaries.

QuipSwap aims to improve cross-chain security through point-to-point exchanges of bridgeless, oratorless, and unwrapped assets.

QuipSwap introduces a bridgeless approach to cross-chain transactions by synchronizing point-to-point transactions.

Postquant Labs, the quantum computing protocol development team, announced that its bridgeless switching protocol QuipSwap will be released to the public soon.

The protocol aims to address two major challenges: cross-chain security vulnerabilities and the imminent threat posed by its own quantum computing network to current encryption standards. QuipSwap is the first solution to minimize trust in cross-chain transactions without the need for bridges, oracles, or wrapped assets, previously the main avenue for billions of dollars in hacking and exploit losses.

Traditional cross-chain solutions rely on centralized intermediaries or smart contract bridges to transfer assets between blockchains, while Quip's new protocol uses a point-to-point mechanism, completely disrupting previous models. This agreement allows both parties to reach an exchange agreement and effectively exchange cross-chain wallet access in a synchronous and trust-free manner.

Colton Dillion, CEO and co-founder of Postquant Labs, said the company's approach to cross-chain transactions can help users participate in the Quip ecosystem without relying on intermediaries, bridges or oracles. "If one party claims to have completed the transaction, the other party will also receive their claim key immediately-there is no room for remorse," Dillion said. "You can operate on any chain, just like doing point-to-point exchanges."

This release is well timed to address a key vulnerability that is often overlooked: quantum resistance. With the development of quantum computing, the current cryptographic foundation of blockchain is facing the risk of being exploited. The Quip team believes that upgrading a single chain is not enough, because to truly achieve quantum resistance, every layer through which a transaction passes must be protected from quantum attacks.

Dr. Richard Carback, chief technology officer and co-founder of Postquant Labs, commented that the company's quantum computing infrastructure is designed to address the security challenges that arise when distributed networks rely on cryptographic systems that are vulnerable to quantum attacks. "You can't run a distributed computing network and miners in the network can crack your encryption," Carback said. "There was no chain that supported quantum computing, so we had to build it ourselves," he added.

After a successful demonstration of the real-time request process at ETHDenver in February, the Quip team has completed the core code base. The agreement has been rigorously tested and has undergone a formal security audit by Oak Security, the results of which were announced today at the time of its public release.

In addition to QuipSwap, quip.network has also successfully deployed quantum-resistant wallets on Bitcoin, Ethereum and Solana, currently in Beta testing, aiming to strengthen blockchain infrastructure before quantum threats strike. All research at quip.network is open source and the goal is to establish an industry-wide standard for quantum computing.
