Briefings

Guest post by Brickken co-founder Ludovico Rossi argues tokenisation requires quantum-ready security due to long-term asset exposure. The G7 Cyber Expert Group released a roadmap in January 2026, while NIST proposed disallowing ECDSA after 2035. Brickken's work focuses on operational efficiency, with a March 2026 Google Quantum AI whitepaper estimating a 500k qubit machine could attack Ethereum signatures in minutes. The article highlights the need for cryptographic agility and interoperability but notes significant uncertainty regarding hardware maturity and commercial viability.

Key points

• The G7 Cyber Expert Group published a coordinated post-quantum roadmap for the financial sector in January 2026.
• NIST's draft IR 8547 proposes disallowing ECDSA after 2035, creating a need for cryptographic agility in tokenised systems.

Context

Tokenisation aims to improve settlement and efficiency, but long-term asset exposure requires quantum-resistant security. The industry faces a gap between current infrastructure and future quantum threats, necessitating proactive planning for cryptographic agility.

Limitations

Evidence is limited to a single guest post without broader industry data. Hardware maturity and commercial viability remain uncertain. The March 2026 whitepaper provides a specific threat timeline but does not confirm practical adoption dates.
