Topic: How would bitcoins for businesses work? (Read 2021 times)

Thank you for all of the responses. I was not trying to troll, just imagining the scalability.

Conceptually, yes, totally agree. But technically I think it's a more challenging than simply installing and running current client.  You can't build something like amazon for instance with a simple shopping cart solution.

if we ever got to this point, BTC would not be the volatile one, USD would be.

for a giant business it would be 1000 times more secure and easier than cash.  No employees would need access to cash, they just accept exact digital payments and verify that they happened.

The customer wont need change.

The employees get paychecks digitally whenever the company decides to pay them.

No need for any traditional manager / money handling risks apart from the incredible volatility of the currency/ commodity value.

Bitcoin itself is a triple-entry system in accounting terms. (Ref: http://iang.org/papers/triple_entry.html )

Just restrict access - I'd code up a simple scraper that would present balances to someone who needed to do the books, but not physical access to the actual client. So you'd separate the data from the actual 'vault'. You could do this with blockexplorer if you knew all the addresses that you've received to.

I'm sure there are other methods, as suggested above.

Companies will hold their "large wallets" off-site, managed by new companies that form to protect against issues such as those mentioned in the OP.

Many people will get wealthy solving these types of security problems.

could you not encrypt the private keys to require one or more private keys for the encryption to be opened up?

situation:
a company with 3 "big bosses" only accepts bitcoins for payment for goods and services. a smart person set a system up for for them so all they each have to do is make a private key on each of their computers. then on a computer that has never been on the internet has been reformatted, still never even having an Ethernet cable plugged in, hell it may as well not even have a NIC. this computer is for storing the wallet and doing the operations to encrypt it. each of the big bosses has 3 copies of their private keys used for encrypting the wallet file/private keys. all 3 private keys must be used. so not 1 person can just decide to spend the money. this could be put into an enterprise client that allows this to happen natively.

also i propose an offline transaction authorization system. this would be where you have a small piece of software putting the packets of information in the flash drive, then you unplug it and plug it into the other computer for which it is intended. the other computer would require you to accept exactly what packets to accept manually. then you must also accept what packets to send manually. This would insure that it is impossible to get viruses even if the other computer is infected, granted you know enough about the system.

Investigate the scripting capabilities of bitcoin transactions.  You can create transactions that require multiple signatures for the recipient to spend them.  The receiving department of a company could forward incoming payments in such a way that any further spending would require the signature of the CEO, CFO and a number of others as desired.  The current client has no UI to create such transactions, but the scripting capabilities in the block chain allow it.  This feature enables many other interesting possibilities.

The digital and fast nature of bitcoins are the solution to this problem.

Client software can be made that accesses access an encrypted wallet which requires that  password to access the encrypted wallet has to be composed from two or more "associates" passwords. Only when the composite password is assembled can funds be sent. This avoids the kidnap scenario above unless the kidnappers decide to kidnap the daughters of all the associates at once.

For the walmart cashier example, the cashier never has to have access to Walmart's wallet.dat. A very simple program can access the wallet for her and confirm to her funds have recently been received from the checkout customer, much how credit cards work. The only reason nowadays cashiers handle cash is because they have to give back change which is not relevant with bitcoins, and because they can't immediately deposit the excess to the corporate bank account.

Consider your cell phone company, and how they protect your credit card details from malfeasance of all sorts. Or your doctor, and how they protect your government id #'s from being sold by nurses to identity thieves.


Long story short, all the smart hackers get jobs in white-hat security protecting companies from themselves.

I think you make a good point.  The small business owner could control all the bitcoin.  For a large business the largest shareholder could hold all the bitcoin and distribute to accounts.  There also might be joint encryptions on wallets.  Thus a 1000 coin wallet might have to get a key from 5 people to be used when 10 people have the key.

Big businesses would require some enterprise bitcoin client solution to be built with tight control of wallets, handling multiple wallets and such.   Current bitcoin client is only acceptable to end-users and small mom and pop shops.

because a theft following a security breach looks little different than an employee pilfering of the company wallet, expect hacking and viruses to get blamed at a disproportionately higher rate.

This creates a paper trail and a "hand off" point, and is quite a bit slower.

How is this different from a ransom demand for US dollars to a swiss bank account?

Your hypothetical does not create a situation in which there is no paper trail.  If the "accountant" has access to a wallet file then you know who has the money, and can prove it in a court of law.

So let's make the hypothetical a little better to address the real issue, and write a movie plot at the same time.

Walmart decides to use bitcoins, to pay for services (note this is an important distinction, if they only accept bitcoins, then only one or a few key stake holders need have access to the wallet file).  Keanu Reeves the top accountant has access to the largest wallet file for payments (he would not have _all_ the money, just the money the owner periodically transfers to a wallet they both have access too adequate for Keanu to conduct business).  

Now Keanu's daughter is kidnapped, and he is told "If you don't transfer 100,000 bitcoins to this addresses within 30 seconds we will kill her. 30, 29, 28..." What do you do? What. Do. You. Do?

Once he transfers the bitcoins they are gone, and both the speed and anonymity unique to bitcoin make catching the criminal at the "hand off" impossible. There is no "hand off".

This is similar to the "perfect crime" scenario outlined in Applied Cryptography page 145.  

However, this is not necessarily a significant advantage. It only improves the executability of the crime in one place the "hand off" which if done properly with cash or other monitory devices is not the weakest part of the crime to begin with.  Also, unlike cash, every transaction that the kidnappers do from that point on with the bitcoin is trackable in the block chain, one wrong step and they will be caught, much more difficult with cash.  Meanwhile all the other weaknesses of the crime, such as being seen kidnapping the daughter, etc. still remain.  

So to answer the question behind your question.  Normal businesses that are mindful of legal and physical security just like they must do now with cash, and accounts and the employees who can access them, will not be exposed to significantly greater risk with bitcoins.  The steps they will need to take to be secure with bitcoins will be different then with cash or accounts, but they are similar and over time will become codified.

It is true that new crimes will be possible with bitcoins that where not possible with cash, credit cards, and banks.  However, that has been true of every major invention throughout time, from the internet and the computer, to the car and printing press before them.  Progress enables.

Bitcoin will not be adopted for what it makes difficult.  It will be adopted for what it makes simple.

Bitcoins in a wallet sent directly are cash. If you don't trust someone to hold a suitcase full of cash don't give them an equivalent amount of your coins to control. If you need them to simply initiate reversible transactions use a system that can do that on top of your cash.

It won't be hard at all for major business deals to get okayed by 6 or 20 people if necessary. A normal sized business will probably pick some amount of operating cash to allow each agent to use directly and another amount for which any transfers will be incomplete without the owner/manager signing off on at the end of the day or whenever.

Lots of ways. Pretty much, the same way you protect cash. You don't leave large amounts of it in insecure places. You audit accesses to the places you store it. You require multiple approvals for operations.

You have to be joking. Walmart wouldn't put any wallet holding large amounts of money on a computer anyone could copy files from.

Just the tiniest bit of common sense 100% stops this. There are no wallet files, the keys are kept on physically secure devices. Transactions can only come in from approved sources and go through verification and logging before being signed and securely exported. The same way you secure stock transactions. The same way you secure wire transfers.

Fundamentally, it's not much different than any other currency. You don't allow untrusted parties near the actual money, period. Any other fiat currency is just as stealable, if not moreso - it's just a database entry,  you don't have to physically cart away gold bricks to commit theft.

A business would simply not have anyone they don't trust interact with the wallet directly. Instead you have the accountant manipulate a database, which is linked to the wallet but does not have permissions to execute transactions. If this weren't a solved problem, the current technology-based financial system would be completely impossible.

you dont need access to the private key to have coins transferred over. you can check to make sure they paid from just looking in the block chain.
