Institutional blockchains raise $1 bn as quantum‑risk threatens $1.3 tn of crypto assets

Three privacy‑focused blockchains aimed at banks and asset managers—Arc, Canton and Tempo—have collectively secured more than $1 billion in funding. Investors cite regulatory clarity and the need for confidential, audit‑able transaction infrastructure as drivers of capital inflow, marking a shift toward private, compliant crypto infrastructure for institutional use.

At the same time, a study by TechGaged warns that roughly $1.67 trillion (about €1.3 bn) of cryptocurrency value remains exposed to future quantum‑computing attacks because the majority of leading blockchains have not yet adopted quantum‑resistant cryptography. The juxtaposition highlights both the rapid growth of institutional crypto solutions and the looming security challenges facing the broader market.
