Original (dhimmels):

Last week the Congressional Research Service updated a the Bitcoin: Questions, Answers, and Analysis of Legal Issues document to better reflect current events.

The document serves as an introduction to Bitcoin and and aims to cover all information necessary for members of the US Congress to make decisions and includes information on many various subjects such as how Bitcoin works on a technical level, Bitcoins benefits and drawbacks, discussions about mainstream usage of Bitcoin and current and future regulation and laws.

Considering the pace of development, particulary in the regulatory environment, over the last months it is then surprising to see such an important document making only minor updates and completely omitting any information relating to some of the heavier events and debates, such as the Auction of the silk road Bitcoins, Pittsburgh planning to accept digital currencies, the document about Bitcoin regulation internationally, the current Discussions about NY regulation and current information about the Federal Reserves Bitcoin Policy.

In fact, the update seems to consist only of statistical updates about prices and market caps and minor changes such as updating the list of current exchanges and a short one-sentence addition about the bankrupty of Mt Gox.

With truly big companies such as Dell starting to accept bitcoin and a large quantity of smaller companies getting started around bitcoin the amount of people who is working with companies that has a relation to bitcoin should probably be significant, yet there is no information in the article about the number jobs that will get affected by regulatory decisions.

Proper and good information is the basis of sound decisions and while this document is a decent primer to the technology behind bitcoin and the current tax and anti-money-laundering regulation there is a clear lack of information regarding the social and financial developments as well as informtion on the environmental aspects of handling money.

Bitcoin and Family Accounting.

With the recent progress in the bitcoin evolution, particularly in regards to usability and multisignature key management, family accounting now has access to new economic tools to support a more reasonable and mindful family economy.

Lets start off with ..

The Parents.

For those parents who choose to have individualized economies and do not share incomes and expenses, bitcoin offers the common single key which allows both parents to retain control over their own funds just as though they had individual bank accounts or wallets. Nothing has changed in this regard.

For those parents who choose to have a shared economy however, bitcoin offers some very interesting multisignature solutions such as the one-of-two and the two-of-two keys which allows two specific use cases.

The one-of-two keys scenario indicates that both parents are capable of spending money from their shared account without the need to ask the other parent for permission. This is good for purchasing things that both parents are responsible for, like groceries.

The two-of-two keys scenario indicates that both parens are capable of spending money from their shared account, but only when both of them agree to do so. This adds an extra layer of protection against careless and/or unfair spending in a shared income environment.

Using a combination of the these two key management options, as well as the single key option, families can now set up a system in which the basic household expenses are easily paid for from a shared account while maintaining consensus on the big economical decisions and helps prevent in-family fraud, giving families a new level of economical stability.

Now lets have a look at ..

The Children.

When a child comes into a family, another layer of complexity is added to the family economy. The simplest of solutions for an economy to accomodate a child is yet another single key which gives the child full access to its funds and leaves the parents with no control at all. In some cases, this might be desireable, but in other cases the parents want to shield their children from making irresponsible economic decisions.

In addition to the one-of-two and two-of-two keys we can now start looking at some very interesting multisignature scenarios involving three parties: one-of-three, two-of-three and three-of-three.

In the one-of-three keys scenario much is as expected. Any one of the parents, or the child, can spend money from the shared account. This proves useful in most of the same situations where a one-of-two key had been useful for the parents given that they trust the child not to spend needlessly.

In the two-of-three key scenario it start to get a bit more interesting. In this case the child can only spend money if at least one of the two parents agree to it. This is great for saving up for specific purposes where the child has some influence over how to spend the money but the parents want to retain enough control to make sure it is not spent for other purposes. This also allows the parents to spend the childs money should both parents agree. Depending on family situtations this might be necessary in order to sustain a functional family economy, particulary in times of economic crisis.

However, there might be cases in which it is undesireable to allow the parents to forcefully spend the child's money and for these cases another type of system is needed which is a combination of those previously discussed.

While I have not yet heard of solutions including specific keys in combination with multisignature keys I believe the programmable money that is bitcoin should be able to support the following scenario as well, we just might need to roll up our sleeves and get coding to see it happen..

Using a one + one-of-two key you can set up an account where the child retain veto against spending, but is not capable of spending itself without one of the parents approval. This is particulary useful for earmarked money, for example an education fund where the parents donate money to the child, but want to control the spending to only go to the specific purpose, while making safeguards as to the future education of the child.

In the three-of-three key scenario we have a place to save money for matters which are truly family related and both parents and the child have veto against any spending. The use is very situational and requires a family with trust and cooperation and is probably not well suited for the youngest of children.

The economic management tools above will also have some implications for ..

Statistics and Accounting.

While using the proposed key distributions above, to create a family economy suited for the particular family needs, is good in and of itself, it also comes with many statistical benefits in regards to accounting.

Since each parent and each child has their own private keys, any spending done by, or agreed to, by any of these family members is recorded into the blockchain with their signatures and this opens up for new ways of visualizing family economics on a person and family level in a fully transparent way.

Which leads us to..

The Conclusion

I sincerely believe that there is an honest need and a real use case for this transparency and accounting as well as the various methods of restricting spending in a co-operational environment and I am glad to see that bitcoin comes with a built-in solution to all of this that doesn't require a family to sign any papers or pay any fees.

While we have no good way of knowing how these new tools will shape the families of the future, I am particularly interested in seeing this being developed. Should the tools arise I will be among the first to try them out!
