Inside Coinbase’s $250 Billion Playbook for Post-Quantum Bitcoin Custody
Coinbase has started work on a post-quantum custody design for about $250 billion in institutional assets, with Yehuda Lindell saying it is meant to work with whichever signature scheme Bitcoin adopts. The plan is framed around a future where a cryptographically relevant quantum computer becomes a threat to Bitcoin security, while Coinbase also wants the same approach to fit other digital assets.

What this rests on
What it means
Each sentence links inside to the piece that supports it.
Institutional Coinbase customers are the group most directly tied to this plan, because the system is being built around custody for about $250 billion in assets. The practical effect today is that Coinbase is designing storage and signing support with a future Bitcoin signature change in mind, rather than for one fixed scheme.
Market reaction
We track BTC, but we only have 1 price point in that window. The series is stored every half hour, so newer events will have it. Computing it from two points would not be a reaction, it would be a coincidence.
