Why was the Quantum Alliance formed?

The Quantum Alliance was formed to develop shared standards for assessing post-quantum security across blockchain networks, wallets and infrastructure. The initiative aims to help crypto projects identify vulnerabilities and prepare for potential quantum-computing threats.

What percentage of Bitcoin (CRYPTO:BTC) supply is potentially exposed to quantum risks?

Bitcoin (CRYPTO:BTC) has approximately 6.04 million BTC, representing 30.2% of its supply, potentially exposed to quantum risks, according to the alliance’s announcement. The estimate reflects existing cryptographic weaknesses that could become vulnerable to sufficiently advanced quantum computers.

When will the Quantum Alliance publish its security guidance?

The Quantum Alliance has announced plans to publish benchmarks and migration guidance, but the announcement does not specify a publication date. Its planned resources are intended to help blockchain projects evaluate and improve their post-quantum security readiness.

How could the Quantum Alliance affect the wider cryptocurrency market?

The Quantum Alliance aims to establish common methods for assessing quantum resistance across blockchain networks, wallets and infrastructure. Its work could help cryptocurrency projects prepare for future quantum threats, although the announcement does not establish a timeline for when those threats will become practical.

Nine blockchain organisations have launched the Quantum Alliance to develop standards for assessing post-quantum security across the cryptocurrency industry.

The initiative focuses on blockchain networks, wallets and infrastructure as developers assess potential threats from future quantum computers.

The alliance aims to establish open standards and verification methods for measuring blockchain systems’ readiness against quantum attacks.

The release estimates that 6.04 million Bitcoin (BTC), or 30.2% of supply, remains quantum-exposed because of existing cryptographic weaknesses.

“Our intention with the Quantum Alliance is to front-load a lot of the complex decision-making when making post-quantum blockchain products and create standards that others can simply pull off the shelf as the industry migrates,” Quantus Founder and CEO Christopher Smith said in a statement.

The alliance will organise its work across four groups covering blockchain migration, post-quantum zero-knowledge systems, wallet security and cross-chain compatibility.

The initiative builds on post-quantum cryptography standards finalised by the US National Institute of Standards and Technology in August 2024, while addressing the lack of shared blockchain readiness criteria.

The Quantum Alliance plans to publish open test criteria, benchmarks and migration designs to help blockchain projects assess vulnerabilities and measure post-quantum readiness against shared standards.
