They include digital cash as a retailer of worth and programming logic denoting its use primarily based on pre-defined situations, reminiscent of a selected validity interval and kinds of outlets.
Earlier than something, the paper outlines a number of issues that have to be saved in thoughts when designing a PBM system.

Proposed PBM system
MAS’ proposed PBM framework is comprised of two principal parts: the PBM Wrapper and digital cash.
The PBM Wrapper, carried out as good contract code, units the foundations for the way the cash can be utilized. These guidelines could be a validity interval, particular retailers or predetermined denominations.
The digital cash, in the meantime, serves as collateral for the PBM system. As soon as the situations of the PBM are met, the underlying digital cash is launched and transferred to the supposed recipient.
The paper additionally outlines the lifecycle of a PBM, delving into its 5 phases. This lifecycle begins with the issuance stage, the place PBM tokens are created and sure by a sensible contract. The tokens signify digital cash and are ruled by particular situations.
Within the distribution stage, the tokens are transferred to supposed holders who obtain them in a wrapped kind. The switch stage permits for the change of tokens between entities in line with predefined guidelines.

If any situations are violated or expire, the PBM tokens enter the expired stage the place they turn out to be completely unusable for the holder. They’ll then be aggregated and destroyed, returning the underlying digital cash to the issuer.
Functions and use circumstances
