Ledger, sync, offline and hardware requirements · C0935
Which ledger technology is the baseline, and could it be replaced?
Designed, not yet built
Short answer
Ledger technology is baseline Hyperledger Fabric; the system must isolate the ledger behind a service interface so that a signed hash-chained log with threshold anchors can replace it for single-owner spheres. That is REQ-3014, a high-priority requirement for the medium and large tiers. Not yet. It is designed in the specification and not built in the pilot. Test in the specification: interface contract tests pass against both back ends.
This is designed, not built.
