America is going (Q)uantum President Trump signs two quantum Executive Orders: 1. Protecting U.S. quantum research from foreign threats: Strengthens counterintelligence efforts (FBI and intelligence community) against espionage (e.g., by China). It also directs the Departments of Defense and Energy to build and host a quantum computer for scientific discovery and tasks Commerce with plans to expand federal investments in quantum companies. 2. Accelerating post-quantum cryptography (PQC) migration: Bolsters federal efforts to transition to quantum-resistant encryption standards to mitigate risks from future “Q-day” when powerful quantum computers could break current public-key cryptography.

🔶MAJOR TECHNICAL UPGRADE: CORE IS SET TO BECOME QUANTUM-RESISTANT Core DAO 🔶 is building quantum resistance into its full stack using NIST-standardized post-quantum algorithms, the same standards the U.S. government adopted across national security systems after 8 years of global review. During the transition, Core transactions will carry both current and quantum-safe signatures simultaneously, with both required to verify. Since $BTC's governance moves slowly by design, Core's execution layer can upgrade independently, making it a quantum-safe environment for $BTC capital while $BTC itself transitions.

"There's nothing worse than trying to protect against quantum computing and then making Bitcoin insecure against regular computing." Adam Back on why hash-based signatures are the conservative post-quantum choice for Bitcoin. Based on a 1979 paper. Decades of analysis. SHRINCS is where Blockstream Research landed.

An estimated $470 billion worth of Bitcoin is exposed to quantum attacks. Alex Shevchenko 🇺🇦 explains why NEAR Protocol was designed with cryptographic upgrades in mind and how the network recently introduced the first approved post-quantum cryptography primitive. • Users can now add post-quantum cryptography (PQC) keys to their NEAR accounts. • Those accounts can hold assets from multiple blockchains, providing additional protection for cross-chain assets. • This marks the first step in NEAR’s broader post-quantum cryptography (PQC) roadmap. • NEAR is the first blockchain to deliver support for approved PQC keys, with future upgrades planned for chain signatures and network consensus NEAR Intents

DNA PROTOCOL UNVEILS POST-QUANTUM ARCHITECTURE ON THE $XRP LEDGER DNA Protocol (DNA Protocol) is anchoring identity commitment hashes on the $XRP Ledger using zero-knowledge proofs and post-quantum cryptography. The system enables users to re-authorize transactions without re-collecting identity data, ensuring immutable verification and long-term cryptographic resilience. This architecture is designed to protect sensitive identity markers from future quantum-computing threats while maintaining on-chain privacy.

Crypto's quantum arms race is accelerating fast In the past two weeks alone: TRON DAO put post-quantum signatures on testnet, NEAR Protocol shipped quantum security in its 2.13 upgrade, and the $XRP Ledger advanced a five-part post-quantum roadmap. Zcash's Tachyon upgrade targets quantum readiness too, per CoinDesk Research. The industry isn't waiting for Q-Day to arrive before hardening its cryptography.

🔥CHARLES HOSKINSON ON BITCOIN’S QUANTUM CRISIS: "TO DO NOTHING WOULD RESULT IN OVER 8 MILLION $BTC BEING STOLEN.” Hoskinson says Bitcoin cannot ignore the quantum threat forever. He suggested the network to either add optional post-quantum signatures, or freeze legacy accounts that fail to migrate. His bigger argument, however, was that Bitcoin lacks a clear governance layer to make that choice. During the Consensus Miami event, he warns of over 50% chance quantum computers could threaten crypto security by 2033.

1/ Starknet was built with quantum risk in mind from day one. STARKs are post-quantum resistant by nature. Native Account Abstraction makes wallets upgradeable by design. Post-quantum wallets are already possible on Starknet. And the remaining pieces require relatively little additional work from our side. In short, quantum computing is not a threat to Starknet’s future. If anything, it plays to Starknet’s strengths.

🚨 JUST NOW: President Trump signs TWO executive orders securing the United States' spot as the WORLD LEADER in Quantum Computing ORDER 1: Launches a national effort to produce a quantum computer capable of performing important scientific calculations. It also aims to develop quantum-enabled sensors and networks within the next 5 years. ORDER 2: Directs federal agencies to transition their computer systems to quantum cryptography (post-quantum cryptography standards) by 2031. It positions the U.S. government to lead wider adoption of these stronger security standards to address future quantum computing threats

Quantum computers pose two threats to Bitcoin: Threat 1: A quantum computer will be built and used to break Bitcoin's cryptography. Threat 2: Even before a QC is built, delaying the preparations to ensure Bitcoin is quantum ready will lead to people losing confidence in Bitcoin. The solution to both threats: ensure Bitcoin becomes quantum resistant via initiatives like BIP 360 + make sure the world knows this will be taken care of in time.
