Project Eleven and privacy-focused proof-of-work blockchain Quantus plan to add Quantus support to Project Eleven’s institutional custody platform in the first quarter of 2027. The integration is designed to let organizations manage keys and approve transactions using hardware security modules, internal policies and audit systems.
Why it matters
Institutions may need to support different post-quantum cryptographic standards across Bitcoin, Ethereum and other networks. Banks and custodians must adapt key management and transaction approvals without weakening controls over who can sign or audit transactions, a challenge that could slow broader institutional adoption.
Project Eleven says its Strongpoint platform separates an institution’s control layer from the signature scheme used by a blockchain. That architecture could let custodians retain existing approval processes and audit trails as networks change cryptography. It does not replace protocol-level adoption of post-quantum security.
Market impact
Quantus uses ML-DSA, a post-quantum signature standard selected by the U.S. National Institute of Standards and Technology. The planned support illustrates how custody providers may prepare for differing chain-level approaches before a quantum threat is imminent.
The timing of computers capable of breaking current public-key cryptography remains uncertain, while network migrations would require broad agreement among developers and users. Project Eleven and Quantus executives argue institutions should plan ahead, treating a surprise quantum advance as a portfolio and fiduciary risk rather than waiting for an emergency transition.
Frequently asked questions
-
When do Project Eleven and Quantus plan to launch institutional custody support?
They are targeting the first quarter of 2027 for Quantus support on Project Eleven’s institutional custody platform.
-
What institutional controls will the planned Quantus support include?
Organizations are expected to manage keys and approve transactions through hardware security modules, internal policies and audit systems.
-
Why could post-quantum migration be difficult for banks and custodians?
Bitcoin, Ethereum and other networks may adopt different cryptographic standards and migration plans, while institutions must preserve approval and audit controls across their holdings.
-
What role does Project Eleven’s Strongpoint platform play?
Strongpoint separates institutional controls from a blockchain’s signature scheme, aiming to preserve approval processes and audit trails as protocols change cryptography.
-
Which post-quantum signature standard does Quantus use?
Quantus uses ML-DSA, a post-quantum signature standard selected by the U.S. National Institute of Standards and Technology.
