# Singapore Crypto Event Highlights Quantum-Resistant Security Challenges By Simon Yoon Canonical URL: https://www.tokenpost.com/news/technology/28606 Published: 2026-10-09T00:30:10.000Z Updated: 2026-10-09T00:30:10.000Z Section: Technology > Quantum + Privacy Day brought crypto builders and industry stakeholders together to examine cryptographic migration, signature security and digital-asset privacy risks. Singapore’s Quantum + Privacy Day brought crypto builders and other industry stakeholders together to examine how digital-asset networks can prepare for threats posed by advancing quantum technology. The discussions focused on which cryptographic signatures may remain secure, how networks could migrate to more robust systems and how privacy risks may change when cryptographic standards are upgraded. NEAR Protocol participated in discussions about protecting digital assets and the need for more advanced cryptographic safeguards. The event highlighted the technical challenge of moving blockchain networks to stronger cryptography while preserving their core security properties. The discussion reflects growing concern about protecting digital assets from quantum threats. Post-quantum security refers to cryptographic systems designed to withstand attacks from quantum computers, which could undermine some methods used to secure blockchain transactions and wallets. The wider industry response includes work on post-quantum wallet and signing technology. [Project Eleven’s acquisition of Riva Labs]() added a cryptography engineering team to its research and product work covering digital-asset custody, blockchain security and post-quantum cryptography. Coinbase is also developing a post-quantum custody plan designed to support whichever signing method Bitcoin (BTC) and other blockchains ultimately adopt. The transition will require networks and custody providers to address signature security, migration processes and the protection of assets held through digital-asset custody systems. ## Links in this article - [Project Eleven’s acquisition of Riva Labs](https://www.tokenpost.com/news/technology/25435)
