Smart contract card bitcoin

1.

They are:

bitcoin

the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's ideas, the open source software was designed and released, and the P2P network was built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system

bitcoin cash

bitcoin cash is a new version of bitcoin with different configurations launched by a small number of bitcoin developers

extended data:

virtual currency refers to non real currency. Well known virtual currency, such as network company's network currency, Tencent company's Q currency, Q point, Shanda company's voucher, Sina's Micro currency (used for micro games, Sina reading, etc.), chivalrous Yuanbao (used for chivalrous road game), silver pattern (used for bixue Qingtian game)

the popular digital currencies in 2013 are bitcoin, Leyte coin, infinite coin, quark coin, zeta coin, BBQ coin, pennies (Internet), invisible gold bar, red coin and prime currency. At present, hundreds of digital currencies are issued all over the world. Popular in the circle & quot; The legend of "bitcoin, Wright silver, infinite copper, pennies aluminum"

2. The program running on the blockchain is usually called smart contract. So we usually change the name of writing blockchain program to writing smart contract
although bitcoin can also write smart contracts, the syntax supported by bitcoin is only related to transactions, and there are limited things it can do
therefore, when it comes to writing smart contracts, it usually refers to Ethereum blockchain that supports the execution of Turing complete programs.

3. Bitcoin is not supported, only point-to-point transmission is allowed

4. In short, a group digs bitcoin on the computer, which is equivalent to a big mine.

5. The following three points are briefly analyzed:
(1) blockchain
since 2013, virtual currency has graally attracted people's attention, and even set off a wave of upsurge of virtual currency. However, many people do not know that the real value is the background technology of virtual currency - blockchain. Virtual currency is only one of the most original applications of blockchain technology, and its rise has brought about a lot of problems, There is also an inevitable reason, that is, blockchain technology endows them with the core characteristics of fairness, impartiality and openness. The practical application of virtual currency is very few, and there is no real value support. Even some virtual currencies recognized by many countries are occasionally traded, not to mention applied. Most of them are just doing price speculation, leading to the price of virtual currency fluctuating, Extremely unstable, because of its price instability, it can not become a real currency. It is precisely because blockchain has the technology gene of fairness, impartiality and openness that almost all banks and financial institutions around the world are studying and using blockchain technology, including UBS, Citigroup, the Federal Reserve, the Bank of England, the Central Bank of China and so on. Why is blockchain so popular? Because it fundamentally enhances the banking instry, supply chain, property management and other trading networks, It is considered to be the core technology with the most potential to trigger the fifth round of disruptive revolution after steam engine, power information and Internet technology 2) (2) smart contract
these advanced applications of blockchain are called "smart contract". Smart contract is the core application that can really bring revolutionary progress. You will find that smart contract is becoming the mainstream of the market, and we will soon enter the era of smart contract
(3) quantum technology
in such a developed world of Internet, how to ensure your information privacy, how to ensure the security of your online banking password, chat records, virtual currency and everything that needs a password, all these are e to the public key and private key encryption algorithm widely used in the current Internet. If this algorithm is decrypted by the current computer, It's almost impossible to complete the task, and it often takes tens of thousands of years or even longer to decrypt. However, within 5-10 years, quantum computers will appear. When quantum computers are used to decrypt, these passwords will only take a few seconds to be decrypted. Our bank funds, social information, and virtual currency will not be safe. Therefore, we can't use quantum computers to decrypt, At present, the research against quantum decryption has become a global hot spot, including the pqcrypto and safecrypto research program supported by the European Union, the crest crypto math research program of Japan, and so on. Major enterprises have also expressed their views, such as Intel's quantum chip, Google's quantum encryption, and quantum communication technologies actively encouraged by governments, So quantum technology is the best future technology. It is not only a spear, but also a shield. It can subvert our current security system and bring us super efficient computing solutions.

6. You're talking about Maya mining machinery. OK? They have been in contact with the mining instry for a long time, and they have a relatively good technical level. Now IPFs is so hot, Maya mining machinery instrial grade mining machinery should be able to bring higher profits

7. Etc and bitcoin are procts of Companies in two different countries. They have different uses and functions. Why do you think there is a relationship between them?
