Nine Blockchain Companies Formed Quantum Alliance to Protect Against Quantum Attacks

Quantus, Midnight, and seven other blockchain companies have formed the Quantum Alliance, an alliance to accelerate the industry's post-quantum readiness. According to Christopher Smith, founder and CEO of Quantus, the goal is to standardize post-quantum products that can be easily implemented in the crypto industry. "We want to preemptively remove many of the complex decisions in creating post-quantum blockchain products and develop standards that others can simply take off the shelf as the industry migrates," he said.

The work will cover migration, ZK-proofs, wallet security, and chain interoperability. In each area, the team intends to harmonize rules so that blockchains with different post-quantum signatures work coherently.

Calls to accelerate preparation for the post-quantum era have intensified following concerns that advanced AI could pose threats comparable to quantum ones. So far, only two groups have publicly advocated for the post-quantum industry: Quantum Alliance and the Bitcoin Security Consortium, supported by BlackRock. Earlier this week, Coinbase intensified calls for an accelerated phased migration of Bitcoin to keep up.

According to Migration Fail, nearly $2.7 trillion of the crypto market is at risk of quantum attack. In terms of readiness, Bitcoin received a "D," Solana and Ethereum an "F." Only Quantus and three other chains have an "A"—they already use post-quantum signatures. Starknet, with notable progress, received a "B." Tron announced it is ready to deploy a PQ update to the mainnet at any moment in Q4 2026. Other blockchains have published PQ plans: some are in the testing phase, others lack specifics.

Meanwhile, some experts believe that a working quantum computer could be possible by 2028, hence the aggressive goal to make most blockchains quantum-ready by 2029. Whether they will succeed is unclear. The industry, led by Ethereum founder Vitalik Buterin, has yet to decide which post-quantum schemes are safe for long-term use. Recent steps show that the industry recognizes the urgency, but whether it will meet the 2029 deadline remains an open question.
