Alex Pruden: Quantum computing threatens elliptic curve cryptography, urgent need for postmodern cryptography, and the Bitcoin community’s philosophical divide | Empire Quantum computing’s rapid advancements pose an urgent threat to the security of digital assets and financial systems. Key takeaways Quantum computing is emerging as a significant threat to elliptic curve cryptography, which underpins many cryptographic systems. There is an urgent need to transition to postmodern cryptography to safeguard digital assets from quantum threats. Recent advancements suggest that fewer qubits are needed to break public key cryptography than previously thought. The current cryptographic systems are vulnerable to both quantum computing and AI advancements. Quantum computers could fundamentally

The post Quantum Computing Threat ‘Mostly a Coordination Issue’ for Bitcoin: Fireblocks CEO appeared on BitcoinEthereumNews.com. In brief Fireblocks CEO Michael Shaulov argued that migrating to post-quantum signature schemes is “mostly a coordination issue” for Bitcoin, rather than a technical challenge. Shaulov flagged North Korean hacking attacks as a roadblock to institutional adoption of crypto. Crypto privacy is “the most important and unresolved issue” for Fortune 500 companies seeking to adopt crypto, he said. The threat posed by quantum computing to the cryptographic signature schemes employed by Bitcoin and other cryptocurrencies is “not actually a threat as people make it out to be,” according to Michael Shaulov, CEO of crypto infrastructure provider Fireblocks. Speaking at the Financial Times Digital Asset Summit, Shaulov argued that “the entire internet industry needs to basically leapfrog and start using post-quantum encryption,” adding that, “generally speaking, we have t

Michael Shaulov argued that changing to a post-quantum cryptographic signature scheme is “not a technical challenge” for Bitcoin.

The post Babylon: Unlocking Bitcoin Staking for the PoS World appeared on BitcoinEthereumNews.com. Babylon is a revolutionary protocol that allows Bitcoin holders to stake their BTC to secure other blockchains—known as Proof-of-Stake (PoS) networks—without ever moving their Bitcoin off its native chain. By using clever cryptography instead of risky bridges or “wrapped” tokens, Babylon transforms Bitcoin from a passive store of value into a productive asset that provides industrial-grade security for the entire crypto ecosystem. The “No-Bridge” Breakthrough Historically, if you wanted to “use” your Bitcoin in DeFi or staking, you had to “wrap” it (turning it into a token like WBTC) or send it across a “bridge” to another network. Both methods are notoriously risky and have led to billions of dollars in hacks. Babylon changes the game by keeping your BTC exactly where it is: on the Bitcoin blockchain. It uses a technology called Extractable One-Time Signatures (EOTS). In simple terms, th
