Bitcoin: The Digital Kill Switch

by Shelby H. Moore III

March 29, 2013

Bitcoin is the first peer-to-peer (P2P) digital currency and payment system to gain significant interest. This month its marketcap surpassed $1 billion.

P2P currencies promise some differences from credit cards, such as increased privacy, no control by authorities, instant signup, lower fees for the merchant, and no chargebacks (buyer at the mercy of the merchant to issue refund if dispute).

Unlike a credit card which allows the merchant to see your details, making unauthorized charges to your P2P account is impossible, unless you allow someone to get your private key. Note credit cards are adding for example Verified By Visa to provide a similar degree of security.

The government control increased on March 13, when FinCEN ruled that transactions for goods and services paying with P2P currency are not regulated, yet exchange to other currencies is regulated and can't be anonymous. Since most users need to exchange from legal tender to and from P2P currencies, some of the purported privacy has already been lost. Also instant signup has been effectively eliminated for many, as now many new users must "practically give a DNA sample" to become verified by exchange providers— however this tsuris may not exist in all jurisdictions.

The anonymity of payments for goods and services is given by the fact that each sender and receiver of a payment is just a number without any other identifying information attached. New numbers can be generated by users at-will. However, the authorities regularly collect information from the internet about usage activity using various means of tracking such as man-in-the-middle routers, spyware, and requests for information from sites that collect information via cookies such as Google's ads and Facebook's Like that appear on many pages of the internet.

So what are the compelling advantages of P2P currencies, since most of the differences from credit cards are being diluted?

For merchants it is the elimination of the 2 - 5% fees charged by credit card companies, the elimination of the ability of the buyer to issue a chargeback, and accessing a new market of highly motivated buyers. In some cases however, the buyer will not like this "no chargeback" provision and prefer to use a credit card.

For the buyer or payer, there appear to be no remaining significant advantages. Even most merchants don't accept P2P currencies yet. The non-merchant has one significant reason to buy digital coins— the expectation of appreciation.

Valuation

The supporters of Bitcoin are projecting very high valuations ranging from $1000 to $1 billion per coin in the future, based on a limit of 21 million coins to ever be created, and a projection of percentage share of global transaction processing.

Notably 50% of Bitcoin's future money supply was issued to the founders and early adopters in first 4 years ended 2012, and by 2016, 75% of the 21 million coins will have been created. By 2020, 87.5%. By 2024, 93.75%. By 2028, 97%.

This accelerated phaseout in the creation of new coins is creating a mad "gold rush" to get in before it is too late. Even though at least 59% (but most likely 75 - 95% since that is only a lower bound that can be measured reliably) are holding long-term and not spending, the skyhigh valuations are based on the hope for adoption by merchants and then increased spending on goods and services in the future.

The 21 million Bitcoins are replacement goods with low barriers to entry and thus can be debased by market share. If competing P2P currencies issue many more coins, then the total finite demand for P2P coins has to be spread between the coins in all P2P currency competitors. However, this spread of market share is not uniform. Today, Bitcoins traded at $75 - $95 with 10.8 million coins issued and Litecoins traded at $0.58 - $0.68 with 2.5 million coins issued. Given real-time exchange between P2P currencies, there is nearly no barrier-to-entry, since merchants will want to accept as many no chargeback currencies as they can if value is rising or stable. Also Gresham's Law dictates that coins will higher issuance will drive coins with less issuance out-of-circulation towards a higher store-of-value. Valuations are also crucially based on market share of transaction processing to be captured in the future, which requires circulation of the currency. So it is quite naive to think that the 21 million coins of Bitcoins are immune to debasement by competitors, unless all competitors suck and have no desirable differences.

Much of the fervor is further amplified with a false sense of altruism under the delusion of being part of a momentus and historic creation of what supporters expect to be the first meritocratic money system— one which can't be debased by the power elite who control the strings on banks in the fiat fractional reserve systems society uses now.

Scaling

For Bitcoin to meet the expectation of investors in its digital coins, the transactions for goods and services has to scale up.

And here is where the hidden diabolical quality of Bitcoin (and Litecoin too) becomes too obvious when the technical details of the design are closely scruntinized by an expert programmer such as myself.

The processing of transactions in P2P currencies is provided by "mining" peers, who provide some Proof-of-Work to insure that double-spends can not exist in the single correct copy of the distributed database. These peers are computers connected to the internet and interacting in a protocol with the other "mining" peers.

To incentivize the "mining" peers to offer their hardware and electricity to this task, they are given the new digital coins created with each new block of transactions. Also they may be offered an optional transaction fee by some payers.

However, the rate of creation of new coins is halving every 4 years, and will eventually stop. Given the fervor the supporters have over non-debasement for meritocratic money system, the end of the creation of new coins is "non-negotiable".

If an attacker can muster 51% of the Proof-of-Work capacity of a P2P system, the attacker can take over the system. There are differences of opinion as to the degree of malicious behavior an attacker could do. However, one unarguable mathematical conclusion is that an attacker that had for example 60 to 90% of the Proof-of-Work capacity could process 60 to 90% of the transactions. If this attacker did not do any thing noticably malicious and did not charge a transaction fee, then virtually all customers would not find it necessary to offer a transaction fee, because over just 3 blocks of waiting time the 60 to 90% becomes 94 to 99.9% of all transactions.* If this was sustained for sufficient months or years when the production of new coins had ended (or declined significantly), then all the other miners would go bankrupt because their costs are not subsidized. Such attacker would then control virtually 100% of all transactions processed. Note this 60 - 90% could be built up over time, because offering free transactions to a percent of the market (when no new coins are being minted), drives some percent of the other miners bankrupt thus increasing the percent the attacker has— it is a snowball effect.

This was explained to some of the developers of Bitcoin who hang out at bitcoin.stackexchange.com, but they claimed it is only an opinion and not a fact. How can math be an opinion?

*First block, 60 to 90% + second block 60 x (100 - 60) to 90 x (100 - 90)% + third block 60 x (100 - 84) to 90 x (100 - 99).

Digital Kill Switch

There is an expectation that large retailers such as WalMart, Amazon, etc., will want to provide the "mining" peers at no transaction fee cost to the buyers, so as to gain a competitive advantage over other retailers.

But we see from the prior section that the incentive is very great to create a cartel that has control over all transactions. Once you have that cartel, you can eliminate those outside the cartel by delaying their transactions or charging transaction fees only to your competitors (billing the competitor, not deducting from the payer in the system). So this is just the credit card fees we have now all over again, except then they will also have a public global record of all transactions in the world (total end of privacy).

Then the government could easily collude with these cartels to turn off the transactions of political dissidents, free speech advocates, gun rights advocates, Ron Paul supporters, and any other classification of terrorist. With control over the processing and the merchants who depend on it, they can easily force an upgrade to the protocol which requires a SSN or other government tax ID to be attached to each transaction.

This is not a stretch at all. The design of Bitcoin and Litecoin encourages it— I go so far as to say they were designed for it given there are alternative designs (I proposed one) that don't have this diabolical possibility.

Having numerous competing P2P currencies does not escape from this diabolical threat, if all of them have the same diabolical design. A non-diabolical design would either have debasement that never ends and/or a minimum transaction fee.

I doubt one can create a non-diabolical P2P currency at any time in future, because the first-mover advantage will apply inspite of low barriers to entry. Because if the users already have Bitcoin and Litecoin, they may not see any compelling reason to add another, in spite of the diabolical quality which does not affect them directly (as a member of the majorty and not a dissidant or other threatened class).

Not Gold

The P2P currency fervor was further stoked by the illusion that they are somewhat like gold. Gold is a private hedge against government malfeasance, it can be traded privately with no public record. P2P currency ownership and transactions are stored in one public database that is never erased forever!

Gold's money supply is always increasing forever (we can mine it in outer space if we run out on earth) and the rate of nominal increase every year is also increasing. Bitcoin and Litecoin are geometrically decreasing the rate of increase of the money supply and will terminate production of new coins at 21 and 84 million respectively. Some people think this makes them even better than gold and silver.

Many people have the illusion these days that inflation is bad and deflation is good. Sorry to bust their bubble, but both transfer wealth to the power elite. The power elite have more savings relative to their expenses, thus they can switch their savings between investments which increase during both inflation and deflation. Whereas, the middle-class are hurt by inflation since they must spend more their income, and they are hurt by deflation, because their wages decline.

If distributed to the middle-class, some minimal debasement is beneficial to offset the guaranteed (government backed stopped) usury interest income the wealthy earn during deflation. I am not a socialist and I love free markets, but the fact is that money is a social collective institution and this is the reality of the math. Either you redistribute algorithmically with debasement and mining of new coins, or you redistribute with taxes and politics. I would much prefer the former.

It is possible to make a P2P currency that more closely emulates gold's money supply. And has the advantage that no one controls its rate of debasement and thus can't manipulate it to create false business cycles.

new P2P currencies

March 29, 2013, 08:57:30 AM

One thing to bear in mind, now that Bitcoin has shown success, everybody and his half-uncle are going to be trying to create a new P2P currency.

Buy low, sell high. Arbitrage is your friend. But no one knows timing, unless they are manipulating and controlling a market.

As an investor, you need to discern which new P2P currencies have the unique features, quality, professionalism, etc... to be taken seriously.

Anyone thinking $10,000 or $100,000+, you are not living in reality. Please don't get angry at me, but markets respond to opportunity cost. There is no way that other smart developers won't respond when now they see $100 per coin created out-of-thin-air.
