Cardano plans quantum-proof upgrades to secure its blockchain against future threats.

Cardano founder Charles Hoskinson announced a strategy to protect the network from quantum computing threats, highlighting it as a key test of blockchain governance. The Cardano community is currently voting on a quantum defense plan, with a formal research proposal expected soon. The plan includes collaborations with academic and industry partners and aims to implement a smooth migration to quantum-resistant technology, leveraging Cardano's agile governance. Meanwhile, Cardano's ADA token has recently dropped amid broader market sell-offs triggered by U.S. inflation data and rising Treasury yields.
