The economics of the bitcoin payment system

The blockchain design enables Bitcoin and other cryptocurrencies to function similarly to conventional electronic payment systems such as PayPal, Venmo, FedWire, Swift, and Visa. Each of them is owned and operated by an organisation that determines the system's rules . Bitcoin provides its users with transaction-processing services which are similar to those of traditional payment systems. This paper models the novel economic structure implied by Bitcoin’s innovative decentralized design, which allows the payment system to . Bitcoin operates on a decentralized public ledger technology called. You’re now willing to purchase bitcoin for the first time. It is crucial to go along in mind that although digit bitcoin costs several thousand dollars, The economics of the Bitcoin payment system can be .

Consequently, they are often regulated or outright owned by government agencies in order to mitigate the welfare loss associated with their monopolistic positions. The innovation in Bitcoin's blockchain design is its ability to operate an electronic payment system without a governing organisation. Rather, a protocol sets the system's rules, by which all constituents abide.

Absent is a central entity that maintains the infrastructure. Any internet-connected computer with enough memory and processing capacity can serve as a miner. Participating miners need to exert computational efforts, and are rewarded for their service to the system. Miners follow the rules of the protocol because it is in their self-interest to do so; when they believe others follow the protocol they will maximize their expected profits by following it as well.

Thus, the protocol is difficult to change as changes require collective agreement on a new protocol. Unlike other payment systems, Bitcoin is a two-sided platform with pre-specified rules. Its two main constituencies are the users who hold balances and engage in electronic transactions, and miners who maintain the system's infrastructure.

A simplified description of the system is as follows. Coin owners broadcast messages in which they announce payments they wish to make. Each transaction is a cryptographically verified message.

The miners vet newly received transactions for legality they verify conformity with syntax rules, ownership, absence of double spending, etc. Each miner maintains the ledger of all past transactions the blockchain where transactions are arranged in blocks.

Every ten minutes, on average, the Bitcoin system randomly selects one miner to add a block of transactions to the ledger, processing all the transactions within that block. When the selected miner adds a block to the ledger, he is said to have mined the block. Equilibrium between many small miners ensures that all miners are in consensus, and only legal transactions are processed.

The Bitcoin protocol limits the block size to 1MB, and thereby the number of transactions within a block. Therefore, the system's throughput is bounded, and does not depend on the number of miners. To provide proper incentives, the system compensates miners for their effort by rewarding miners when they are selected to mine a block. The reward consists of newly minted coins and the transaction fees paid by the transactions processed in the block.

The protocol specifies how many newly minted coins are awarded in each block. This number is cut in half approximately every four years. In contrast, transaction fees are not fixed by the protocol; users choose the transaction fees they pay. Thus, the blockchain design carries an economic innovation in that no participant has the power to set or modify fees or rules of conduct or otherwise control the system.

Users and miners are price-takers. Users are provided protection from monopoly pricing: even if the system becomes a monopoly, there is no monopolist who charges monopolist fees. However, for the system to function properly it must raise sufficient revenue from the users to fund the required infrastructure.

In a recent paper, we translate the above description to an economic model that allows the analysis of the long run behaviour of the system, when miners are compensated solely from transaction fees Huberman et al. The analysis aims to answer two sets of seemingly disparate questions:. The absence of a Bitcoin-controlling organisation renders both questions non-trivial. The model asserts a single answer to both questions: the system's congestion due to its limited throughput leads users to pay transaction fees to gain processing priority.

These very fees fund the miners. This answer raises follow-up questions regarding social efficiency, stability, robustness and parameter choice. The equilibrium behaviour of users and miners creates the distinctive features of the transaction fees, revenue, and infrastructure level.

Miners prefer to process transactions with higher fees, but cannot affect the transaction fees chosen by users. Therefore, in equilibrium a miner selected to process a block will choose to process the transactions with the highest fees. The total revenue from fees paid by users is equal to the total payment to miners.

Because miners can freely enter or exit the system, each miner's expected profit is zero, and the amount of revenue determines the number of miners. Thus, even if the system as a whole is a monopolist, it provides its service at cost. Users compete for service priority by paying transaction fees, as if processing priority was auctioned by the miners.

Because of the stochastic nature of the system, even if the system has sufficient capacity on average, some transactions will suffer from delays. Higher fees secure higher priority and therefore less delay. Analysis of the implied congestion-queueing game shows that, in equilibrium, transaction fees are equal to the additional delay costs imposed on others. Thus, absent congestion and delays, users need not pay transaction fees, and transaction fees increase with the level of congestion.

Moreover, this trade-off is quite sharp: in the absence of significant congestion, transaction fee revenue will be miniscule. The independence of the system's capacity of the number of miners implies that the number of miners does not affect congestion. Although the model focuses on the long run, its insights apply also to today's minting-heavy environment. Namely: i miners' expected profit is zero; ii the higher the congestion, the higher the transaction fees; iii the higher the transaction fees, the harder is the proof of work performed by the miners.

Pertaining to ii , Figure 1 depicts the theoretical and actual relation between average daily block size and the corresponding average transaction fee; congestion is associated with block size being close to 1MB.

Moreover, it is empirically clear that significant congestion is associated with meaningful revenue generation. The Bitcoin system offers an alternative to regulating a monopoly or controlling prices via market competition. Bitcoin can be a monopoly in the sense that all potential users are using the Bitcoin system.

But even then, its service will not be priced at the monopoly price. Instead, pricing is determined in equilibrium. However, the equilibrium price varies with congestion and is unlikely to be optimal. Significant congestion and costly delays are necessary for raising revenue. He believes that bitcoin is a non-productive asset. Buffett's close associate Charlie Munger is even more direct in his disdain. Trading cryptocurrencies is "just dementia" according to Munger. Bitcoin is "worthless" and a "turd".

Did I make myself clear? There is nothing to support bitcoin except the hope that you will sell it to someone for more than you paid for it. George Soros , answering an audience question after a speech in Davos, Switzerland in , said that cryptocurrencies are not a store of value but are an economic bubble. Nevertheless, they may not crash due to the rising influence of dictators trying to "build a nest egg abroad". James Chanos , known as the "dean of the short sellers", believes that bitcoin and other cryptocurrencies are a mania and useful only for tax avoidance or otherwise hiding income from the government.

Bitcoin "is simply a security speculation game masquerading as a technological breakthrough in monetary policy". Two lead software developers of bitcoin, Gavin Andresen [87] and Mike Hearn, [88] have warned that bubbles may occur.

On 13 September , Jamie Dimon referred to bitcoin to as a "fraud", [89] comparing it to pyramid schemes , and stated that JPMorgan Chase would fire employees trading while the company released a report critical of the cryptocurrency.

Some journalists, [94] economists, [95] [96] and the central bank of Estonia [97] have voiced concerns that bitcoin is a Ponzi scheme. In , Eric Posner , a law professor at the University of Chicago, stated that "a real Ponzi scheme takes fraud; bitcoin, by contrast, seems more like a collective delusion. In billionaire Howard Marks investor referred to bitcoin as a pyramid scheme.

Zero Hedge claimed that the same day Dimon made his statement, JP Morgan also purchased a large amount of bitcoins for its clients. Financial journalists and analysts, economists, and investors have attempted to predict the possible future value of bitcoin. In April , economist John Quiggin stated, "bitcoins will attain their true value of zero sooner or later, but it is impossible to say when".

In December , finance professor Mark T. The "death" of bitcoin has been proclaimed numerous times. Forbes magazine declared bitcoin "dead" in June , [] followed by Gizmodo Australia in August Peter Greenhill, Director of E-Business Development for the Isle of Man, commenting on the obituaries paraphrased Mark Twain saying "reports of bitcoin's death have been greatly exaggerated".

Some economists have responded positively to bitcoin while others have expressed skepticism. Velde, Senior Economist at the Chicago Fed , described it as "an elegant solution to the problem of creating a digital currency". Louis , stated that bitcoin is a threat to the establishment, which he argues is a good thing for the Federal Reserve System and other central banks , because it prompts these institutions to operate sound policies.

Free software movement activist Richard Stallman has criticized the lack of anonymity and called for reformed development. Marcus calls bitcoin a "great place to put assets" but claims it will not be a currency until price volatility is reduced.

In November , three US government officials testified at senate hearings that "Bitcoin has legitimate uses". According to the Washington Post , "Most of the other witnesses echoed those sentiments. Most bitcoin transactions take place on a cryptocurrency exchange , rather than being used in transactions with merchants. Prices are not usually quoted in units of bitcoin and many trades involve one, or sometimes two, conversions into conventional currencies.

In and bitcoin's acceptance among major online retailers included only three of the top U. Bitcoin is "not actually usable" for retail transactions because of high costs and the inability to process chargebacks , according to Nicholas Weaver, a researcher quoted by Bloomberg. High price volatility and transaction fees make paying for small retail purchases with bitcoin impractical, according to economist Kim Grauer.

Bitcoin started to be accepted also for real estate payments in late The first recorded sale of a house in exchange for bitcoin happened in September , when Texas based Kuper Sotheby's International Realty brokered the deal using bitpay. Two months later, a first recorded sale of apartment in the world and first real estate property in Europe was sold for bitcoin in November in the Czech republic.

The Czech real estate agency HOME Hunters brokered a deal of a 3-room apartment for a Russian buyer without using a payment service providers at all. Some U. Merchants accepting bitcoin, such as Dish Network, use the services of bitcoin payment service providers such as BitPay or Coinbase.

When a customer pays in bitcoin, the payment service provider accepts the bitcoin on behalf of the merchant, directly converts it, and sends the obtained amount to merchant's bank account, charging a fee of less than 1 percent for the service. Due to the design of bitcoin, all retail figures are only estimates. Bitcoin companies have had difficulty opening traditional bank accounts because lenders have been leery of bitcoin's links to illicit activity.

The request was motivated by oil company's goal to pay its suppliers. Some Argentinians have bought bitcoins to protect their savings against high inflation or the possibility that governments could confiscate savings accounts.

Other methods of investment are bitcoin funds. The first regulated bitcoin fund was established in Jersey in July and approved by the Jersey Financial Services Commission. Forbes named bitcoin the best investment of To improve access to price information and increase transparency, on 30 April Bloomberg LP announced plans to list prices from bitcoin companies Kraken and Coinbase on its , subscription financial data terminals. The number of bitcoin millionaires is uncertain as people can have more than one wallet.

Bitcoin is useful for crowdfunding. He was shown by local TV company with a broadsheet "Hi mom, send bitcoins". The decentralization of money offered by virtual currencies like bitcoin has its theoretical roots in the Austrian school of economics , [] especially with Friedrich von Hayek in his book Denationalisation of Money: The Argument Refined , in which he advocates a complete free market in the production, distribution and management of money to end the monopoly of central banks.

Bitcoin appeals to tech-savvy libertarians , because it so far exists outside the institutional banking system and the control of governments. Bitcoin's appeal reaches from left wing critics, "who perceive the state and banking sector as representing the same elite interests, [ From Wikipedia, the free encyclopedia.
