Abstract
The invention provides techniques for enabling offline devices that do not have an active connection to an account-based CBDC network to participate in CBDC network processes such as asset transfers. This is enabled by defining an offline protocol that governs the handling of such processes in an offline state. A collateral chain is provided by the CBDC network that links together multiple accounts so that an account lower down in the collateral chain can be used to settle a transaction in the case where an account higher up the chain does not hold sufficient CBDC to settle the transaction. On the device side, offline transaction messages are exchanged that enable either device to commit the transaction to the CBDC network once the device obtains an active connection to the CBDC network.
