TSMC Chuangxin BTC

1. The concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. According to the idea of Nakamoto, the open source software is designed and released, and the P2P network on it is constructed. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system
unlike all currencies, bitcoin does not rely on a specific currency institution to issue. It is generated by a large number of calculations based on a specific algorithm. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity

according to the notice on preventing the financing risk of token issuance, there is no approved digital currency trading platform in China. According to China's digital currency regulatory framework, investors have the freedom to participate in digital currency transactions at their own risk

warm tips: the above information is for reference only. Before investing, it is recommended that you first understand the risks existing in the project, and understand the investors, investment institutions, chain activity and other information of the project, rather than blindly investing or mistakenly entering the capital market. Investment is risky, so we should be cautious when entering the market

in terms of cloth storage and mining, I recommend Heshu hardware wallet and jiajiabao intelligent home miner. The core advantage of the proct is safety

take sum hardware wallet as an example. The advantages of sum hardware wallet are as follows:

1. The private key seed is encrypted layer by layer, physically isolated and never touched the Internet.

firstly, when creating the wallet, the seed password is generated and stored in the local encryption chip, and the 10 bit payment password is required

then, the transaction is made in the wallet. At this time, the user needs to enter the payment password to obtain the private key to digitally sign the transaction, and the transaction is completed. In addition, the private key seed is permanently stored in the chip, which is physically isolated and never touches the Internet. There is no need to worry about my password being stolen by hackers

Second, the bank system verifies the financial level motherboard and encryption chip

uses the bank system to verify the financial level motherboard, and the private key seed is stored in the chip. If the proct is stolen or lost, and destroyed by malicious violence, the chip will trigger a self destruct circuit, and immediately permanently and irrecoverably delete all the information in the area

Third, it supports the withdrawal of global bitcoin ATM, which is convenient and fast

the reason why digital assets attract the attention of many fields in the world is that it is creating a global fast circulation, and the larger the circulation field is, the wider the scope is, and the higher its use value is. The core of digital assets is the medium it acts on among currencies. The Heshu wallet has built-in many mainstream exchanges in the world. It can trade digital assets anytime and anywhere. With one machine in hand, it can walk around the world without worry, and no longer have to worry about exchanging foreign currency

Different from conventional digital wallets, multi signature wallets need the authorization of multiple key holders to transfer digital currency, so the security of multi signature wallets is higher. Ordinary Wallet: a wants to transfer a bitcoin to X. A only needs his signature (using the private key) to complete the transaction. Sum Wallet: if a wants to transfer a bitcoin to x, a multi signature verification is set (at least two signatures of Abc3 indivials are required to transfer the money), then a needs B or C to complete the signature (using the private key) when a wants to transfer the money to X. I hope I can help you. Thank you

3. As for the recording disk, Tsinghua can use it, and pioneer is the best recorder (personal opinion), but there are few good pioneer agents in China. Sony is good, read disk and burn are excellent, as long as you do not object to using Japanese goods, is a good choice, do not use MSI. Don't use Samsung. I've tried all these, garbage in garbage (personal opinion). Support the domestic procts, please use Jianxing domestic best (or personal opinion), pirates favorite, thick leather and easy to operate (unit boys say) read disk is good, burning is also good. The price is also cheap. After sales, anyway, my side is OK. If you have any problems, you can replace them. I just recommend the brand and model. You can see for yourself. It's almost the same anyway
in addition, you can go to the recording bar to have a look. It's all about how to choose and buy. You can also learn from the bad goods you buy. I went there before I bought it
the above are personal opinions, please don't scold me. Hee hee^^

4. Avant garde is one of the founding enterprises of DVD alliance. It participates in the formulation of a series of specifications for DVD and other optical drives, and has strong proction capacity
don't buy domestic ones. I've bought four domestic ones, and they all went up in about a year. Later, it was replaced by the pioneer, which is still in use. Later, I bought a pioneer's recorder. I can't remember how much I have engraved on HD every day. Now I can still engrave, but I can't read it
generally speaking, I think pioneer is OK.

Internet public beta Chapter 7 mining contract
I quit the game quickly, feeling better than usual, No wonder when Shenglong company introced the game, it said that playing the game is equivalent to sleeping. It doesn't delay your work and let you have leisure after work. I washed it in a basin of water, changed into a white sportswear, and ran to the park for exercise. This is a habit that I have developed since I was a child. I am breathing fresh air in the park. I feel that there is no landscape in the civilized game in reality. With this alone, the game will be popular, and there are several times more time in the game than in reality, It's equivalent to hundreds of years of life. There were several old people playing Taijiquan nearby. I also played a set of natural boxing, which my grandfather taught me when I was young. After watching it at 7:23, I bought some fried dough sticks and steamed buns on my way home
when I went back to the place where I lived, it was more than 20 square meters, and it was 400 meters a month. He Yun lived in his relative's house. When I walked into the room, I saw a single bed with a straw mat on it, two big green backpacks on the left, my clothes on it, a washbasin on the right, and a faucet. I washed myself at the tap. Fortunately, it's summer. I sat on the bed, eating and calling He Yun, but after a few rings, no one answered. I guess he is now

In fact, the programmer's day also belongs to bitcoin. 1024 is the tenth power of 2, one of the basic units of measurement of binary counting. To put it bluntly, binary is a string of 0 and 1 characters. It can be said that programs and data in any computer network are based on this{ RRRRR}

generally speaking, the development of bitcoin and blockchain is mainly driven by technology, which started with programmers and has always been inseparable from the presence of programmers. In this process, programmers such as vshen, BM, CZ have realized the counter attack of life

but now the development of blockchain is still relatively small in the circle of programmers. I hope that programmers can actively participate in today's festival, and not the friends of programmers can take good care of the programmers around them. Maybe it's the next Nakamoto
