Institutional digital asset infrastructure has to remain controllable through change: new cryptographic requirements, new vendors and the failure of components that a bank depends on.
On 30 September 2026, Silence Laboratories and LF Decentralized Trust co-hosted Bank Scale Digital Asset Design: Post-Quantum Infra, Ownership and BCP in Miami Beach during Sibos week. Jay Prakash and Hadley Stern moderated the roundtable.
Designing the full custody stack
The discussion connected quantum readiness with the choices institutions make about wallets, key management and policy engines. These components do not all evolve on the same schedule. An architecture needs room for changes in cryptography and hardware without losing the institution’s existing controls.
The roundtable also examined where banks need ownership of critical infrastructure. Choices about custody models and the use of hot, warm or cold environments depend on the risks and workflows an institution needs to support.
Continuity has to work in practice
A central takeaway was the need to test the transaction path under vendor failure. Recovery documentation has value only if the institution can use it to regain the ability to operate.
Distributed cold custody was another area of interest, bringing the properties of multi-party control into a part of the stack traditionally associated with tightly constrained operations.
The group included participants from banks’ technology ecosystem, digital asset infrastructure providers and the LFDT community. For Silence, the discussion reinforced the need to treat cryptography, institutional control and continuity as connected architecture decisions.
This was the first of two DeCompute Miami roundtables; the second focused on private workflows for an agentic economy.
