Tweet I have seen many people asking for help in data mining forums and on other websites about how to choose a good thesis topic in data mining.
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. With any payment system, there is an ability to create new assets, or misdirect existing assets, all with no more work than a few button pushes.
To address this, we use the approach of separation of concerns to address the agency problem of holding owners' assets, but protecting them from internal attack.
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.
The general schema that is advised to Issuers is as follows [ 50 ]. In order to limit the creation of value, for each issuance, a special account is designated as the mint, or the creator of value. 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 Thesis about internet banking the probity of the governance regime.
Then, a manager account is designated that receives any new float from the mint, and also returns any redemptions. It thus becomes the Issuer's responsibility to ensure that the mint account is rarely used, and then with full authorisation and wide scrutiny.
Meanwhile, the manager's account is regularly used, but holds only limited amounts of value for day to day requirements. The above are general techniques that are supported within the Ricardo system, but are as applicable elsewhere.
Certain features get specific support, such as value caps on accounts and target account limitatons. Note how these protection techniques that we use are partly outside the domain of the technical system.
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.
Finally, in dynamic governance, we provide for monitoring of key values by the user community, and thus share the auditing burden.
These values can be audited in an issued currency within the Ricardo system: Total value of digital float: Amount currently held in the issuance manager's account. From this account is drawn new value to be sold, or into this account, old user value is redeemed.
The balance sheet of the currency, which is effectively the above numbers, and the total of user value outstanding. As a balance sheet, the total float, minus the manager's account, should equal the outstanding users' total value. With some limitations, it is useful to provide summaries of movements such as bought and sold values through the manager's account, the mint account, and number of user accounts.
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.
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.
Accounting In order to meet the conflicting objectives of privacy and flexibility, Ricardo uses a conventional accounting model with some additional features: Accounts are units of allocation of ownership, and are not identities.
A user may create these on demand, and likewise dispose of them. Lower layers must provide some mechanism for these accounts. Sub-accounts manage a particular form of value within an account.
The sub-account is simply the intersection of ownership authentication the account with the value description the contract. Transactions are movements of value from one account to another, within the sub-account of the instrument.
The backend accounting engine is responsible for guaranteeing that each transaction is atomic and persistant. The result of transaction completion is the issuance of a signed receipt. Each transaction settles in real time, as measured by the issuance of the receipt.
Both backend and client keep a list of receipts as the sub-account. In order to meet Governance layer requirements for open auditability, some accounts must present balance sheets on demand, and select accounts must be examinable.
Because of the top level requirement for cheapness, the accounting model was designed for complete reliability, right up to the support desk level. It does this by employing a group of non-obvious techniques:Cloning.
In biology, the activity of cloning creates a copy of some biological entity such as a gene, a cell, or perhaps an entire organism. This article discusses the biological, historical, and moral aspects of cloning mammals. The main area of concentration is the moral dimensions of reproductive cloning, specifically the use of cloning in order to procreate.

JUST WAR AND IRAQ: I said below that I have yet to hear a satisfactory answer on why a quick war with Iraq would not be more just than the status quo of immiserating sanctions.
Now Glenn Reynolds links to a Michael Walzer essay on a war with Iraq that provides one response. The key grafs: "Defending the embargo, the American overflights, and the UN inspections: this is the right way to oppose. The Internet of Things (IoT) is opening the potential for billions of connected smart devices to communicate with each other using the nearly ubiquitous Internet Protocol technology.
