BTC in Hangzhou

1. The topic of blockchain and bitcoin has gone crazy recently

in fact, Mr. Xiao Zaojun paid attention to this very early. Last year, I wrote a popular science article about blockchain and bitcoin. At that time, the price of bitcoin seemed to be $3000, and many people suggested that I start. After thinking about it, I still didn't buy it

later, bitcoin soared and plummeted, peaking at $20000, and then quickly fell to $8000. I'm both sorry and glad<

today, I've also rerouted that article (with some revisions). I hope it will help you to know more about blockchain and bitcoin technology

in my opinion, whether you invest in bitcoin or not, whether you believe in blockchain or not, first of all, you should fully understand them

today, let's talk about blockchain and bitcoin

well, here's the thing -

these days, if you haven't heard of bitcoin, it's really out

when you see the glittering gold coin, is it a moment of spirit

in other words, bitcoin is not an ordinary fire nowadays. Some friends always come to ask Mr. Xiao Zaojun about it. Even when you take the subway, you can hear people around you talking about it<

bitcoin has been used for several times, and the most influential one is this:

children's shoes must be familiar, and indivial children's shoes are expected to be shocked

Yes, this is the blackmail window that popped up after computer poisoning when wannacry blackmail virus broke out in May 2017

the words in the blue box are the way blackmailers ask for ransom - "only accept payment in bitcoin", and others are not recognized. At the same time, the blackmailer also kindly tells you how to buy bitcoin

as a result, bitcoin, along with the blackmail virus, swipes the screen all over the world, greatly enhancing its popularity.

Recently, bitcoin has been swiping the screen frequently. One reason is that the story of "making rich" of bitcoin is surprising. The other reason is that the rise and fall of bitcoin is too crazy. After entering 2021, bitcoin is in a rising trend. Although it has declined ring this period, it has always remained at a high level

12 years ago, Nakamoto, a Japanese American, created bitcoin. It is said that Nakamoto himself has never appeared, but the bitcoin he created is crazy. This year, the value of bitcoin hit new highs, first US $30000, then US $40000. On February 22, 2021, the value of a single bitcoin hit a record high, reaching US $58000 each

is it sure to make money by investing so much money in "mining"? The answer may disappoint you again. Bitcoin's "wealth making" is based on the price rise. Once bitcoin's price falls and it is no longer so valuable, investors may lose all of it

some experts have warned that the bitcoin market is the easiest to be manipulated, because bitcoin is mainly concentrated in the hands of some people, and a virtual currency is so expensive that it can not be separated from the hype of these few people. At the same time, there is no sound and mature regulatory mechanism for the bitcoin market in the world, so the risk of investing in bitcoin is great

therefore, for ordinary people, it is better to stay away from bitcoin and "mining", don't you think

3.

It's not against the law

The laws and administrative regulations in China do not prohibit the proction, holding and legal circulation of bitcoin, nor do they prohibit the sale of bitcoin mining machines

2. The investment and transaction of "virtual currency" represented by bitcoin are on the rise. For this kind of virtual goods generated in the Internet environment after the development of Internet technology, there are policy and commercial risks in related transactions. However, under the premise of not violating the mandatory provisions of laws and administrative regulations, the contract signed by the parties is a valid contract

3. Bitcoin is generated by "miner" and "mining", and "miner" can be assumed by anyone in any place in the world. "Mining" is a process in which "miner" provides certain computer computing power according to the open source software provided by the designer, and obtains the special solution of the equation through complex mathematical operations, The miner who gets the special solution gets a certain amount of bitcoin reward

Because bitcoin is based on workload proof, it is related to computing power. To have computing power, we need to consume power, so its power consumption is very large. It is precisely because of such a large power consumption that the safe and stable operation of bitcoin system can be guaranteed

extended information:

according to the data of btc.com website, up to now, the computing power of the whole bitcoin network is about 51.65 eh / s, which is equivalent to 1.84 million bitcoin S15 (28T computing power, 1596w power) mining machines in operation, and the daily power consumption is about 69.92 million kwh. Divided by the current proction of 1800 bitcoins per day, excluding other costs, each bitcoin will consume 38800 kwh of electricity. "

from this point of view, although the current price of bitcoin is expensive, the cryptocurrency market website coinmarketcap.com shows that the current unit price is about $7900, but the cost of mining a bitcoin is not low at all

XTT (Xin time token), based on Ethereum erc20 platform, is a decentralized digital currency carrier based on blockchain as payment technology

Ethereum is an open source public blockchain platform with smart contract function, which provides decentralized Ethernet virtual machine to process point-to-point contract through its special cryptocurrency ether (ETH)

the concept of Ethereum was first proposed by vitalik buterin, a programmer, from 2013 to 2014, inspired by bitcoin, to the effect of "next generation cryptocurrency and decentralized application platform", and began to develop through ICO crowdfunding in 2014

extended data:

background

bitcoin has created the first decentralized cryptocurrency, and has fully tested the feasibility and security of blockchain technology in more than five years

the blockchain of bitcoin is actually a set of distributed database. If a symbol bitcoin is added into it and a set of protocol is specified, the symbol can be transferred safely on the database without trusting a third party. The combination of these features perfectly constructs a currency transmission system bitcoin network

however, bitcoin is not perfect, and the scalability of the protocol is a deficiency. For example, there is only one symbol in the bitcoin Network - bitcoin, and users can't customize other symbols. These symbols can represent the company's stocks or debt certificates, which will lose some functions

In addition, a stack based scripting language is used in bitcoin protocol. Although this language has some flexibility to realize functions such as multi signature, it is not enough to build more advanced applications, such as decentralized exchanges. Ethereum is designed to solve the problem of insufficient scalability of bitcoin

5. You're talking about spark entertainment. That night, some of you entered the YY channel of face-to-face interview with bitcoin celebrities co sponsored by bitcoin home, China dogcoin and bitcoin elder martial sister. As a result, some people swipe the screen and abuse there, resulting in the channel being blocked. But the people in the coin circle still provided you with as much help as possible. The next day, the major media in the coin circle reported on it. Mainstream mass media also reported. As a member of the coin circle, I don't want bitcoin to be used by these MLM organizations. Although I have reminded them many times before, they are really abusive. You can tell me your story of being cheated, and I will help you as much as possible.
