The Ethereum Foundation announced a new Post Quantum team on Friday as crypto markets continue discussing quantum computing risks. The nonprofit organization elevated post-quantum security to a top strategic priority for the network.

Ethereum researcher Justin Drake said Thomas Coratger will lead the new team. Emile, a cryptographer behind leanVM, will provide support. Drake said Ethereum is moving from background research to active engineering work.
The foundation plans to start bi-weekly developer sessions focused on post-quantum transactions next month. Antonio Sanso will lead the sessions. The work will cover cryptographic tools, account abstraction and transaction signature aggregation.
Ethereum is backing the research with funding. The foundation announced a $1 million Poseidon Prize to strengthen the Poseidon hash function. A second $1 million initiative called the Proximity Prize will support additional post-quantum work.
Multi-client post-quantum consensus test networks are already running. Multiple teams are participating in weekly interoperability calls. The foundation will host a post-quantum event in October and a post-quantum day in late March before EthCC.
Bitcoin traded just above $89,000 on Thursday, down 30% from its early October peak. Gold reached a record $4,930 per ounce with a 1.7% gain. Silver jumped 3.7% to $96.
Since November 2024, bitcoin has fallen 2.6% while silver gained 205% and gold rose 83%. The Nasdaq climbed 24% and the S&P 500 added 17.6% over the same period.
Castle Island Ventures partner Nic Carter said Bitcoin’s underperformance is due to quantum computing concerns. He called it “the only story that matters this year.” Carter described the price action as mysterious.
Onchain analyst Checkmatey disagreed with the quantum theory. He said the market has been moving on supply and positioning rather than quantum fears. The analyst compared blaming quantum risks to blaming market manipulation for price drops.
Checkmatey pointed to sovereign gold buying as the driver for precious metals. He said Bitcoin saw selling pressure from long-term holders in 2025. The selling would have ended previous bull markets multiple times over.
Bitcoin investor Vijay Boyapati offered a simpler explanation. He said large holders unlocked supply once Bitcoin hit $100,000. The level represented a psychological barrier for many whales.
Quantum computing uses advanced processors that could potentially break current encryption methods. The technology could expose wallet keys if machines become powerful enough. Most developers say such capabilities remain decades away.
Blockstream co-founder Adam Back called the quantum threat extremely remote. Bitcoin Improvement Proposal 360 already outlines quantum-resistant address formats. The proposal provides a gradual migration path if needed.
Jefferies strategist Christopher Wood removed Bitcoin from a model portfolio earlier this month. Wood cited quantum computing as a long-term risk factor. Developers say any necessary upgrade would take years to implement.
Bitcoin’s quantum security debate continues as Ethereum builds new defenses while price action reflects traditional supply dynamics.
