Certain features get specific support, such as value caps on accounts and target account limitatons. Transactions are movements of value from one account to another, within the sub-account of the instrument.
With any payment system, there is an ability to create new assets, or misdirect existing assets, Thesis managerial accounting with no more work than a few button pushes.
This account is placed in the hands of a reliable professional source such as an accountant or lawyer, who will hopefully only have an interest in using the account under the probity of the governance regime.
Each transaction settles in real time, as measured by the issuance of the receipt. Mirroring the Governance Model It is also worth noting that when a currency is reserved by an underlying asset for example, if a gold-denominated currency had physical metal escrowed to reserve it then the above governance features should be mirrored for the reserves.
Finally, in dynamic governance, we provide for monitoring of key values by the user community, and thus share the auditing burden.
Both backend and client keep a list of receipts as the sub-account. Sub-accounts manage a particular form of value within an account. Because of the top level requirement for cheapness, the accounting model was designed for complete reliability, right up to the support desk level.
The above are general techniques that are supported within the Ricardo system, but are as applicable elsewhere. Rather than being outside scope, their discussion here is simply a reflection of the claims that the total security of the system is a holistic issue, and governance is the layer where we solve the security challenges that remain after we have attempted to solve as many as possible in the lower layers.
This problem is normally handled by separating out management of day-to-day assets with the creation of assets in the system, and increasing the work required for any fraudulent transactions.
It does this by employing a group of non-obvious techniques: Lower layers must provide some mechanism for these accounts. The backend accounting engine is responsible for guaranteeing that each transaction is atomic and persistant.
That is, to continue the example of gold, there should be separate parties responsible for the ingress and egress of metal into storage, and there should be independent verification of the number of bars currently placed in escrow. Structural Governance Within structural governance, we consider the question of insider fraud, the theft of both digital value within the Financial Cryptography system and of any physical value that underlies the virtual value managed by the system.
The balance sheet of the currency, which is effectively the above numbers, and the total of user value outstanding. Total value of digital float: Accounting In order to meet the conflicting objectives of privacy and flexibility, Ricardo uses a conventional accounting model with some additional features: The sub-account is simply the intersection of ownership authentication the account with the value description the contract.
A user may create these on demand, and likewise dispose of them.Financial Cryptography in 7 Layers Ian Grigg   - Abstract: Financial Cryptography is substantially complex, requiring skills drawn from diverse and incompatible, or at least, unfriendly, disciplines. Caught between Central Banking and Cryptography, or between accountants and programmers, there is a grave danger that efforts to construct Financial Cryptography.
