Solana news: The network’s post-quantum push reveals harsh tradeoff: security vs speed - CoinDesk

Tech Share Solana's quantum-threat readiness reveals harsh tradeoff: security vs speed While Bitcoin developers scramble to find a solution and Ethereum prepares for 'Q-day,' Solana is trying to get ahead of that scenario. By Margaux Nijkerk|Edited by Aoyon Ashraf Apr 4, 2026, 8:00 a.m. Make preferred on Here is how Solana is getting ready for quantum threat. But there is a catch (Getty Images) What to know: The Solana Foundation is working with Project Eleven to test quantum-resistant cryptography as concerns grow that future quantum computers could break current blockchain security. Early tests show major tradeoffs: quantum-safe signatures are up to 40x larger and made the network roughly 90% slower, raising questions about scalability. Solana News More For You Encryption Supremacy: Zcash and Privacy in the Age of Scale By CoinDesk Research Mar 31, 2026 Commissioned byGenZcash Most crypto privacy models weaken as blockchain data grows. Encryption-based models like Zcash strengthen. CoinDesk Research maps the five privacy approaches and examines the widening gap. Why it matters: As blockchain adoption scales, the metadata available to machine learning models scales with it. Obfuscation-based privacy approaches are structurally degrading as a result. This report provides a comprehensive comparison of all five major crypto privacy architectures and a framework for evaluating which models remain durable as AI capabilities improve.
