# 2100 Bitcoins to buy a pizza

## How valuable is the “One” coin, otherwise I would not have exchanged bitcoin for pizza back then

The exchange rate of bitcoin is different every day, for example, if you have 100 yuan today, You can exchange two bitcoins, then tomorrow, maybe you can exchange five bitcoins, so every day, the fluctuation of bitcoins is very large, if you are not very good at this, then you don’t easily In fact, Bitcoin is also an investment. Many people invest in real estate, but some people think that this currency is also an investment method. They are optimistic about its potential value. Throw in bitcoin.

## 『Wu』How long does it take to mine a bitcoin

Bitcoin is a network virtual currency. The Bitcoin network generates new bitcoins through “mining”. The so-called “mining” is essentially using a computer to solve a complex mathematical problem to ensure the consistency of the distributed accounting system of the Bitcoin network. Assuming that the mining computing power is 100Mhash/s and the total daily computing power is 4000Ghash/s, then 3600 bitcoins can be mined every 24 hours.

China’s computing power has accounted for more than 75% of the world’s total, which means that 75% of the world’s bitcoins are made in China. So how long does it take to mine a bitcoin?

In the past, bitcoin was very easy to “dig”, and it could be done by ordinary computer CPU. Just download the software to “solve the problem” automatically. However, as the currency price rises, more and more people want to “solve the problem”, and mining becomes more and more difficult. Now, the amount of computation required to mine a Bitcoin is simply beyond the reach of ordinary people, so don’t even think about ordinary computers.

Industry insiders said that in 2014, 500,000 yuan of electricity produced 100 bitcoins per day, and the electricity cost alone cost 5,000 yuan per piece. But by now, the same cost has more than doubled, with electricity costs as high as 10,000 yuan per bitcoin.

In the generation mechanism of Bitcoin, the mining reward is decreasing. At the beginning of Bitcoin’s birth, miners could get 50 bitcoins for each page of the ledger, and then 25 bitcoins were rewarded for each page, which decreased in turn. Just like digging for gold, you dig a lot at first and then less and less. Every time the new reward is reduced by half, it is called the Bitcoin production halving.

Assuming that the mining computing power is 100Mhash/s, the total computing power per day in 2014 is 4000Ghash/s, and 3600 bitcoins are mined every 24 hours.

Now, we can understand the difficulty of mining Bitcoin in this way, which is equivalent to throwing a number less than 100 million 50 from 100 million dice. Whoever throws it first will get the accounting right. At this point, 100 million and 50 is a hash value, the process of throwing dice is called hash collision, and the unit of mining computing power is how many hash collisions per second.

At present, the computing power of the entire Bitcoin network reaches 2.36 trillion hash collisions per second, which is equivalent to the number of water droplets in more than 200,000 standard swimming pools with a length of 50 meters. But even with such a large computing power, it takes about 10 minutes to collide with a hash value that meets the requirements.

Bitcoin had its first production halving in 2012. In July 2016, Bitcoin had its second production halving. The current reward for recording a page of the ledger is 12.5 bitcoins. The next halving will take place around 2020, and the total number of bitcoins will not increase by 2040, and the total number will be 21 million.

Then on the 22nd, the cryptography enthusiast “jercos”, taking advantage of the merchant’s discount, bought two pizzas for \$25 and sent them to Laszlo, and received 10,000 bitcoins as promised.

The Bitcoin community has since celebrated May 22, when the iconic transaction took place, as “Bitcoin Pizza Day.” A Twitter account even popped up with daily updates on the bitcoin value of the two pizzas on that day. Also, every time the price of Bitcoin breaks new highs,�� Both the deal and Laszlo will be brought up to be “ridiculous”.

The two pizzas are worth \$76.3 million at current bitcoin prices.

## Extension information

The concept of Bitcoin (BitCoin) was originally proposed by Satoshi Nakamoto in 2009, and it is an open source software designed and released according to Satoshi Nakamoto’s ideas. software and the P2P network built on it. Bitcoin is a P2P form of digital currency. Peer-to-peer transmission means a decentralized payment system.

Bitcoin economy uses a distributed database composed of many nodes in the entire P2P network to confirm and record all transaction behaviors, and uses cryptographic design to ensure the security of all aspects of currency circulation. The currency system used to have no more than 10.5 million for 4 years, after which the total number will be permanently capped at 21 million.

Bitcoins can be cashed out and can be exchanged into the currencies of most countries. Users can use bitcoin to buy some virtual items, as long as someone accepts it, they can also use bitcoin to buy real-life items.
