Nine cryptocurrency organizations launched the Quantum Alliance to establish clear, verifiable standards for quantum-resistant blockchain technology. Formed in mid-October 2026, the group includes founding members Quantus, American Fortress, and Intmax. The alliance plans to publish open security guidelines focused on protecting transaction signatures, wallet keys, zero-knowledge proofs, and cross-chain compatibility.

Current blockchain networks rely heavily on elliptic-curve cryptography, which could become vulnerable to future quantum computers running specialized algorithms. An estimated 6.04 million to 6.4 million Bitcoin, representing roughly 30.2% of the circulating supply, sit at addresses with public keys already exposed on-chain. While general post-quantum standards were finalized by NIST in August 2024, blockchains face unique obstacles such as expanded signature sizes, fee implications, and decentralized upgrades.

The group aims to translate general post-quantum standards into practical frameworks that developers can adopt without building solutions from scratch. Investors and developers should monitor whether larger blockchain platforms, wallet providers, and major custodians adopt the group's open frameworks or if the initiative remains a niche working group.

## Key points

- Nine crypto firms created the Quantum Alliance on October 15-16, 2026, to define post-quantum blockchain standards.
- The group will publish open criteria across four areas, including wallet security, migration, and cross-chain compatibility.
- Between 6.04 million and 6.4 million Bitcoin have exposed public keys, leaving them potentially vulnerable to future quantum attacks.
- Foundational members include Quantus, American Fortress, and Intmax, with plans to make all security outputs publicly available.

## Questions and answers

### What is the Quantum Alliance in crypto?

The Quantum Alliance is a group of nine crypto organizations formed to create and test verifiable post-quantum security standards for blockchain networks and wallets.

### Why are quantum computers a threat to Bitcoin?

Quantum computers could use algorithms to derive private keys from exposed public keys on the blockchain, potentially putting up to 6.4 million exposed Bitcoin at risk.

### Who are the founding members of the Quantum Alliance?

The alliance's publicly named founders include Quantus, American Fortress, and Intmax, alongside six other blockchain organizations.
