Bitcoin new currency
According to Beijing time on October 24, Jeff garzik is one of the few key developers of bitcoin's underlying software, so he knows the shortcomings of bitcoin's blockchain at his fingertips. So he decided to create a better digital currency
he named the currency metronome and said it would be the first virtual currency to be used on different blockchains
this mobility means that if a blockchain dies e to developers' infighting or no one is using it, metronome users can transfer their money to other places. Kajik said that would help metronome maintain its valuation and ensure its long-term survival. In order to create metronome, kajik founded the start-up company bloq. Metronome will be officially launched at the money 20 / 20 conference in Las Vegas on Tuesday, he said
metronome will be generated and supported by automatic distributed software, which is neither controlled nor changed by anyone. The software will start auctioning metronome currency in December and will retain and use the proceeds from the auction to drive the price of the currency. The rest of the project will be open source, so anyone can develop applications for metronome
bloq will provide developer tools for enterprise users. Of the 10 million metronome coins to be auctioned in December, bloq and other organizations that help create and promote metronome will keep 2 million of them. Every 24 hours, 2880 new metronome coins are born
metronome avoids problems that users often encounter when they want to transfer from one blockchain to another. That is, users must sell one cryptocurrency they own and then buy another. This creates transaction costs and may lose the potential appreciation of the currency sold. With metronome, none of this is a problem
when users want to transfer metronome to another blockchain, they will get a digital receipt. They can then send the receipt to another blockchain and add metronome to that blockchain
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 monetary institution to issue. It is generated by a large number of calculations based on a specific algorithm
bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses the design of cryptography to ensure the security of all aspects of money circulation

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"
Bitcoin is a kind of electronic currency / network virtual currency
bitcoin: also known as "bitcoin", is a kind of network virtual currency. Internet users can use bitcoin to buy some virtual goods, such as clothes, hats, equipment, etc. in online games. Internet users can also use bitcoin to buy real goods
on February 26, 2014, Joe Manchin, a Democratic senator from West Virginia, issued an open letter to a number of regulatory authorities of the US federal government, hoping that the relevant authorities would pay attention to the status quo of bitcoin's encouraging illegal activities and disrupting the financial order, and demanded that actions be taken as soon as possible to completely ban the electronic currency
from 12:00 noon on January 24, 2017, China's three major bitcoin platforms officially began to collect transaction fees
extended data:
currency features:
1, decentralization: bitcoin is the first distributed virtual currency, the whole network is composed of users, and there is no central bank. Decentralization is the guarantee of bitcoin's security and freedom
2, global circulation: bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin
3, exclusive ownership: private key is needed to control bitcoin, which can be stored in any storage medium in isolation. No one can get it except the user himself
4, low transaction cost: bitcoin can be remitted free of charge, but a transaction fee of about 1 bitfen will be charged for each transaction to ensure faster transaction execution
5, no hidden cost: as a means of payment from a to B, bitcoin has no cumbersome limit of quota and proceres. If you know the other party's bitcoin address, you can pay
6, cross platform mining: users can explore the computing power of different hardware on many platforms
advantages of bitcoin:
1, it is completely decentralized, without issuing institutions, it is impossible to manipulate the number of issues. Its distribution and circulation are realized through open-source P2P algorithm
2, anonymity, tax exemption and supervision free
3, robustness. Bitcoin is completely dependent on P2P network and has no distribution center, so it cannot be shut down externally. Bitcoin price may fluctuate and collapse, and many governments may declare it illegal, but bitcoin and its huge P2P network will not disappear
4, borderless and cross-border. Cross border remittance will go through layers of exchange control agencies, and the transaction records will be recorded by many parties. But if you trade with bitcoin, enter the digital address directly, click the mouse and wait for the P2P network to confirm the transaction, a lot of money will pass. It does not go through any regulatory agencies and will not leave any cross-border transaction records
5, Shanzhai people are difficult to survive. Because bitcoin algorithm is completely open source, anyone can download the source code, modify some parameters, recompile, and create a new P2P currency
but these counterfeit currencies are very fragile and vulnerable to 51% attacks. Any indivial or organization, as long as it controls 51% of the computing power of a P2P currency network, can manipulate transactions and currency value at will, which will be a devastating blow to P2P currency
many counterfeit coins die in this link. The bitcoin network is robust enough. If you want to control 51% of the computing power of the bitcoin network, the number of CPUs / GPUs required will be astronomical
the weakness of bitcoin
1, the fragility of trading platform. The bitcoin network is robust, but the bitcoin trading platform is fragile. Trading platform is usually a website, which will be attacked by hackers or shut down by competent authorities
2, the transaction confirmation time is long. When bitcoin wallet is first installed, it will consume a lot of time to download historical transaction data blocks. While bitcoin transaction, in order to confirm the accuracy of data, it will take some time to interact with P2P network, and the transaction will be completed only after the whole network is confirmed
3, the price fluctuates greatly. Due to the intervention of a large number of speculators, the price of bitcoin for cash fluctuates like a roller coaster. Making bitcoin more suitable for speculation rather than anonymous trading
4, the public did not understand the principle, and the traditional financial practitioners resisted. Active netizens understand the principle of P2P network and know that bitcoin has no legal person to manipulate and control
but the public doesn't understand, and many people can't even distinguish between bitcoin and q-coin“ "No issuer" is the advantage of bitcoin, but in the view of traditional financial practitioners, "no issuer" currency is worthless
bitcoin does not rely on a specific monetary institution to issue, it is generated through a large number of calculations of a specific algorithm. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions. The decentralized characteristics and algorithms of P2P can ensure that bitcoin can not be artificially manipulated by mass proction. The design based on cryptography can only make bitcoin be transferred or paid by real owners. This ensures the anonymity of money ownership and circulation transactions.
Bitcoin is not the currency of a country, but a virtual currency
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
bitcoin is e-cash similar to e-mail. Both parties need "bitcoin wallet" similar to e-mail and "bitcoin address" similar to e-mail address. Just like sending and receiving e-mail, the remitter pays bitcoin directly to the other party through a computer or smart phone according to the recipient's address
extended data:
unlike all currencies, bitcoin does not rely on specific currency institutions to issue. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, And the use of cryptography design to ensure the security of all aspects of money circulation
the decentralized feature and algorithm of P2P can ensure that it is impossible to artificially control the value of bitcoin by mass manufacturing. 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
Yes in the early morning of December 20, the price of bitcoin broke through $24000 , and reached a record high of $24156. Bitcoin is up 24.65% this week and 233% this year
According to Kang Lu, senior analyst of fire currency, the unilateral rise of the market is not a healthy performance of the market, but a certain correction of the market is a healthy performance of the market. Kanglu believes that the market will not continue to rise, and breaking the new high does not mean that the market will continue to rise all the way, but it will have a strong impact on the psychological level of investors, and the market may form a certain buying consensus According to the securities times, on Friday, the U.S. Treasury proposed new regulations on digital currency regulation, requiring some cryptocurrency dealers to provide information about their identities in order to curb the use of this new technology by criminals for anonymous asset transfer. The proposal has 15 days for public comment. Affected by the news, bitcoin once fell by about $200 in the short term, breaking through $22880, but soon recoveredit is learned that the new regulation mainly aims at allowing the holder of the unique digital key to store the cryptocurrency and trade directly with others without going through the accounts of financial institutions. This kind of account usually exists in the form of U disk, computer or mobile phone software
such accounts are usually not associated with an indivial's name and address, and regulators believe that compared with the banking system, cryptocurrency is more attractive in the eyes of criminals and money launderers
under the new rules, banks and cryptocurrency trading platforms will have to keep records of customers' cryptocurrency transactions and counterparties in any transaction over US $3000 to verify their identities. According to the U.S. banking regulation called "travel rule", financial institutions must share specific information when transferring money to each other
in addition, banks and digital currency trading platforms must report to FinCEN every 15 days any cryptocurrency transactions involving unmanaged wallets and exceeding US $10000
if you want to get so much income in a month, you can try to dig some unknown counterfeit currency. But there is no guarantee that you will make a profit. Maybe you can't even dig up the electricity bill. But the money you g up should sell for that much money
if you really want to mine, I suggest you buy Avalon 3 single-mode miner for mining, because bitcoin is the most reliable currency.
try to buy a new version of the graphics card as much as possible, so that the mining time is short
the card that can mine and the a card that has very good performance have no problem running the game. After you buy it, run down the doughnut and see if the temperature is too high. If the temperature is normal, it's OK
you can buy cards like 7950 and 7970 for 1000 yuan, with high cost performance.
you can buy cards like 7850 for 550 yuan, which is better than 999 yuan graphics card like gtx750ti.
