A great first in the history of cryptocurrency! Usually competing players decide to come together to protect the Bitcoin network from the quantum threat. In total, there are nine giants of finance and the crypto industry to commit $15 million to the Bitcoin Security Consortium. Launched on July 23, 2026, the project sends a clear message: institutions now consider the security of Bitcoin as a long-term strategic issue.
In brief
- 9 financial and crypto giants launch the Bitcoin Security Consortium with an investment of $15 million over three years.
- Up to 6.9 million BTC could be exposed to advances in quantum computing in the long term.
- Institutions want to anticipate future risk and build investor confidence in the Bitcoin network.
Quantum security of Bitcoin: an alliance far from trivial
On July 23, 2026, Strategy founder Michael Saylor announced on launch of the Bitcoin Security Consortium. This initiative is of particular importance for one good reason: it is the first time that traditional finance and the crypto industry are organized around the same technical objective. This is to preserve the security of Bitcoin in the era of quantum computing.
According to the press release published by Strategythe consortium has 4 founding members :
- BlackRock, the world’s leading asset manager;
- Fidelity, the wealth management giant;
- Coinbase, the first US crypto exchange listed on Nasdaq;
- Strategy, the world’s largest institutional bitcoin holder with over 847,000 BTC.
To give substance to this approach, members have committed $15 million over three years. These funds will be used to finance research, development and awareness around quantum threats weighing on the Bitcoin network.
Another detail attracts the attention of crypto analysts: the initiative comes six months after the creation of a council of experts by Coinbase. The latter brings together well-known figures, to name only:
- Scott Aaronson (quantum computing pioneer, University of Texas);
- Dan Bonehn (cryptographer, Stanford);
- Justin Drake (Researcher, Ethereum Foundation).
In April 2026, this council published a 51-page report:
Certainly, the quantum threat is not imminent. However, it is clearly on the horizon. Migrations to post-quantum cryptography should begin immediately.
Quantum threat: 7 million BTC would already be in danger!
There Bitcoin network security rests on two cryptographic pillars:
- ECDSA (Elliptic Curve Digital Signature Algorithm) for transaction signatures;
- SHA-256 (256-bit Secure Hash Algorithm) for PoW mining.
In theory, a sufficiently powerful quantum computer could derive a private key from a public key. Enough to compromise crypto funds.
According to the Coinbase Quantum Advisory Board Reportapproximately 6.9 million BTC are held in UTXO (Unspent Transaction Output). The public key is exposed there onchain. This figure includes approximately 1.7 million BTC stored in P2PK (Pay-to-Public-Key) addresses inherited from the Satoshi era. Some are even attributed to the anonymous creator of Bitcoin.
Other analyzes estimate this vulnerability to 6.5 million BTC. This represents approximately 32.7% of the total bitcoin supply. However, they use slightly different data points.
The consortium has no intention of modifying the Bitcoin protocol
The members of the project agree on this point: this prerogative belongs to the developers of Bitcoin Core as well as the community. THE role of the consortium consists in fact of:
- fund research;
- coordinate the actors;
- accelerate awareness among institutional investors.
More concretely, the $15 million committed over three years will be used to:
- support the development of technical proposals like BIP-360 and BIP-347: the first allows public keys to be maintained off-chain, while the second reactivates the OP_CAT opcode to enable single-use signatures resistant to quantum attacks.
- Promote BIP-361: This proposal aims to phase out legacy signatures and prohibit sending crypto funds to vulnerable addresses.
- develop migration tools for institutional Bitcoin holders.
What this means for investors and the crypto market
THE launch of the Bitcoin Security Consortium sends three strong signals to the crypto market:
- institutional;
- technical;
- regulatory.
The quantum threat is no longer a niche subject reserved for cryptographers. It now finds itself at the center of attention of the world’s largest financial institutions. Enough to reassure hesitant institutional investors.
The financial commitment of $15 million is modest compared to the members’ capitalizations. However, it demonstrates that the long-term security of Bitcoin is today considered a public good deserving collective financing.
By anticipating future regulatory requirements, the consortium positions bitcoin as a proactive asset in the face of crypto regulation.
Certainly, the $15 million committed to the Bitcoin Security Consortium is not enough to guarantee the network’s resistance to quantum computing. Nevertheless, the initiative marks a real change of posture within the crypto sphere. It remains to be seen whether this unprecedented cooperation will keep its promises of transparency.
