Beyond Bitcoin

The use of “pi” as a nickname for the currency is no accident. The unit symbol for PI currencies is π, the symbol for the mathematical constant pi. Pi is not only a symbol for one of the greatest constants in math; it is also a symbol for something new: an online currency that’s secure, convenient to use, and hard to fake.

PI currencies are sometimes called cryptocurrencies, but that term may be confusing because there are also cryptocurrencies that aren’t PI currencies. Some people think “cryptocurrency” means any type of online currency at all; others say it means only Bitcoin or other types of cryptocurrencies that use cryptography to secure transactions.

The coins in PI currencies are stored anonymously on your computer. You don’t need to know who keeps them there, or how much they are worth—just how many you have and what they add up to on your screen.

A cryptocurrency is a decentralised digital currency that uses peer-to-peer technology to operate online. Bitcoins are the most popular form of cryptocurrency. Cryptocurrencies use cryptography (the technique of making things secret) to control the creation of new money and verify the transfer of funds, operating independently of any central bank or single administrator.

Although there are many cryptocurrencies, bitcoins are the best known and most widely traded. Bitcoin is a cryptocurrency, a digital asset designed to work as a medium of exchange that uses cryptography to control its creation and management, rather than relying on central authorities.

The idea behind cryptocurrencies is that they are more efficient than traditional financial systems for transferring funds from one party to another. The process by which transactions take place can be completely transparent and anonymous.

Bitcoin was launched in 2009 by an individual or group going by the pseudonym Satoshi Nakamoto., although some later uncovered evidence showed this was actually an engineer at the European Banking Authority working with a team of researchers at the International Monetary Fund.

Cryptocurrencies can be used to launder money, carry out illegal activities, buy contraband items or pay for services or goods in locations where they may not be legal; it’s hard to say how common these activities are because cryptocurrencies aren’t regulated and there’s no

Pi is a peer-to-peer currency based on cryptography. It uses a variant of the bitcoin protocol, but it has a few key differences. The way that Pi works makes it useful for more than just payments and transfers.

Pi was created by Ulf Andrén in 2009. He named the coin after the mathematical constant pi or 3.14159265358979323846264338327950288419716939937510582097494459230781640628620899862803482534211706798214808651328230…

The currency was inspired by an earlier attempt to create a digital currency called “pi dollars.” At that time, Andrén’s employer (a Swedish company called datacom) had a contract from an American company to establish a digital cash network. The pi dollars were being used as examples in the contract, so he went through with the project, despite having no technical experience.

This essay is about cryptocurrencies. These are ways of transferring value electronically, usually in a form that only the people involved can understand. Bitcoin was the first such currency, and it is by far the biggest. (This essay is not about money in general; it’s about a particular kind of money.)

Although the details of Bitcoin and its predecessors have changed, the basic idea behind cryptocurrency has remained the same. The idea is to make electronic money that does not rely on trusting a third party, and that can be used online or in real life.

Imagine a piece of paper with numbers printed on it. You could use that paper to buy a computer for $100 and later sell it for $100. But what if you didn’t trust anyone? What if you couldn’t be sure that no one would later show up and try to take advantage of you?

And what if you didn’t trust banks? And what if you wanted to keep your money somewhere other than in a bank account?

Cryptocurrency is a way of making electronic money without relying on banks or anyone else. It works like this: A central authority creates new currency units (for example, bitcoins) out of thin air and distributes them to everyone who wants them. People who use the currency don’t have to trust each other; they just have to trust the system. And they don’t have to keep their money at the bank; they keep it in their own digital wallets, which are connected to the system by encrypted links.

It is easy to get excited about the possibilities of mathematical theory. It is also easy to put too much faith in the future. When things are going well, people tend to think they know everything. When they go badly, they think they know nothing. When something works, it seems obvious. But when something doesn’t work, people blame themselves for not having thought of it first.

For a long time, there was no such thing as Bitcoin or other cryptocurrencies. But mathematicians had been thinking about the concept of an “internet currency” for years; Nick Szabo’s 1994 paper “The Nation State of the Internet” was one early example.

In 2008, Satoshi Nakamoto published a paper describing how to create such a digital currency and how it would operate. This was the start of Bitcoin.

The first cryptocurrency is called Bitcoin. There are now dozens of cryptocurrencies, but it is the one that has made the most headlines.

Bitcoin is probably best thought of as a distributed database (and like any database it can be used to store information in a number of different ways). A cryptographic hash serves as a kind of digital signature for every Bitcoin transaction, and all the transactions are recorded in a public log. The log is called the blockchain, and it’s where all the controversy over money laundering and drug trafficking comes from.
