$20M pledged by top firms to defend Bitcoin against future quantum computer threats

In July, Galaxy and a consortium including BlackRock, Coinbase, and Fidelity committed $20 million to develop defenses against quantum computing threats to Bitcoin. About a third of all Bitcoin, roughly 6.9 million BTC, is already exposed on-chain due to public key visibility, raising security concerns. Companies like Coinbase and BitGo are actively building quantum-resistant custody solutions, while debates continue on how imminent the quantum threat really is, with estimates ranging from 10 to 20 years away. This funding aims to hedge against uncertainty and accelerate development of post-quantum cryptographic tools to protect Bitcoin's future security.

Bitcoin quantum safety is the story's subject, with Pluang market data providing context. As of Sep 29, 2026 17:02 WIB, 42 of 50 major cryptocurrencies rose today. Notable movers include ADA at Rp4.563 (+4.37%), SUSHI at Rp4.725 (+4.19%), and COTI at Rp233 (-4.06%).
