Terms of digital currency transaction
bitcoin is the originator of digital currency and the most valuable virtual currency. Because blackmail virus only takes bitcoin, it has entered the public view. The soaring price of bitcoin in 2017 has attracted a large number of investors to enter the digital money market. Because the number is small, it is only 21 million, which has a strong deflationary attribute
of course, I am extremely optimistic about the future of bitcoin. Of course, many people are not optimistic about digital currency. Here, it is most pertinent to quote Krugman's view:
"at least for now, buying bitcoin is still a good investment. But that doesn't mean the experiment was successful. The original intention of establishing a monetary system is not to make those who hold money rich, but to make transactions convenient and benefit the whole economy. And none of these bitcoins came to us. "
reborn currency
a protocol currency issued by reborn, which is the base currency of reborn network. It can circulate in the whole reborn network, with a total amount of 100 billion, and graally decreases with the increase of transactions. Reborn currency is the only common currency in ripple system, which is different from other currencies in ripple system, Ripple labs (formerly known as opencoin) is the operating company of ripple coin
unlike bitcoin, reborn is a kind of transaction protocol, which is called smart contract in technical terms. It supports people to pay in any currency, and does not need a central data exchange center, so the transaction confirmation time of ripple is only 35 seconds, while that of bitcoin is 10-40 minutes
Ethereum
Ethereum is the name of currency used in Ethereum, which is used for payment calculation in Ethereum virtual machine. Ethereum is a blockchain that can be used to deploy decentralized applications. It is an open source computer platform and blockchain platform. At the end of 2013, it was founded by vitalik buterin, a Russian programmer
there is a key difference between the blockchain technologies used by Ethereum and bitcoin. Ethereum's data processing speed is faster than that of bitcoin, because once agreed, Ethereum's system will automatically apply to the terms and conditions in the contract
unlike bitcoin, the value of Ethereum depends on whether the applications on the platform of Ethereum are prosperous or not, just like the price of oil will rise with more machines using oil
bitcoin cash
bitcoin cash is a branch of bitcoin. In order to solve the problem of long transaction time of bitcoin, at 20:20 on August 1, 2017, a small number of mining machines began to use 8m block to start mining, and the transaction confirmation speed was thousands of times faster than that of bitcoin using 1m block
strictly speaking, however, there are different opinions on whether this is a new branch of bitcoin or another kind of "counterfeit currency". But now the offer of bitcoin cash is nearly 20000 yuan, so it's not too much to use it as a kind of "Shanzhai coin" to divide bitcoin traffic
IDA coin, ADA in English, is a proct of Cardano project. The total amount of Aida is 4.5 billion yuan, and 3 billion yuan will participate in the subscription. Among them, 2.5 billion ADA will be used for platform subscription, 500 million for the financial support of the development company's operating company, and 1.5 billion ADA coins will continue to be issued in the form of block awards
Cardano is a project started in 2015 to change the way cryptocurrency is designed and developed. This project is aimed at technical reformers, technical improvements to bitcoin and existing platforms. If bitcoin, Ethereum and other projects have many other shortcomings, Cardano can solve them<
lightcoin
a currency based on bitcoin protocol, but it does not require very high computing power, and it can also be mined by ordinary computer. Lightcoin's algorithm comes from the algorithm designed by Dr Colin Percival for tarsnap secure online backup service (backup for Linux and other open source operating systems)
for a long time, there has been a voice that "lightcoin will replace bitcoin", which is impossible. In the future, there will probably be a variety of cryptography currencies in the world, but any kind of counterfeit currency can not replace the mainstream position of bitcoin, no matter how excellent its algorithm is compared with bitcoin<
stellar currency
stellar currency, a digital currency project initiated by Jed McCaleb, the former founder of ripple, is used to build a decentralized gateway between digital currency and legal tender. It will be provided to users in the form of free distribution, and its supply online is 100 billion, of which 95% of the amount of star coin is used for free distribution
star is a diversified team. The board members include Keith rabois, former COO of square, Patrick collison, CEO of stripe, Jackson Palmer, co-founder of dogcoin, and naval Ravikant, co-founder of angellist, who will be the consultant of the project< New economy movement, or NEM, was founded on January 19, 2014. The founder is a mysterious person in bitcointalk.org forum called utopianfuture. The original intention of utopian future was to build a second-generation digital currency NXT. He then realized that NXT's distribution model was unreasonable, so he devoted himself to NEM with egalitarian distribution
as a kind of cryptocurrency, new coin does not need much computing resources to maintain the operation of nodes. The proof of importance (POI) engine of NEM reces the threshold of computing resources to participate in non-traditional blockchain<
dascoin
formerly known as black coin, is a kind of counterfeit currency of bitcoin, which focuses on anonymous function. There are many innovations, such as master node network, fast payment, mixed currency anonymous technology, proposals can vote, and developers have fixed budget support. The core consists of a unique incentive P2P network. Miners are rewarded for maintaining blockchain security; The main node holders are rewarded for verifying transactions, storing data and providing a variety of services
the feature of anonymity meets the needs of some investors for absolute privacy. Although bitcoin is also widely used in money laundering and other illegal transactions e to its anonymity, it is only "pseudo anonymity", and the transaction of bitcoin can still be traced back to the traders themselves.
Blockchain blockchain is a new application mode of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism and cryptocurrency algorithm. Is a shared distributed ledger in which transactions are permanently recorded through additional blocks
2, block - block
in the bitcoin network, data will be permanently recorded in the form of files, which we call blocks. A block is a set of records for some or all of the latest bitcoin transactions and is not recorded by other previous blocks
3. Node -- a of the ledger operated by the participants of the blockchain network
Decentralization is a phenomenon or structure, which can only appear or exist in a system with many nodes or in a group with many indivials. The influence between nodes will form nonlinear causality through the network5. Consensus mechanism
consensus mechanism is to complete the verification and confirmation of the transaction in a very short time through the voting of special nodes; For a transaction, if several nodes with unrelated interests can reach a consensus, we can think that the whole network can also reach a consensus
6. POW -- proof of work refers to how much money you get depends on the amount of work you contribute to mining. The better the performance of the computer, the more money you will be given
In POS mode, your "mining" income is directly proportional to your currency age, and has nothing to do with the computing performance of the computer8. Smart contract
smart contract is a kind of computer protocol which aims to spread, verify or execute the contract in an information way. Smart contracts allow trusted transactions without a third party, which are traceable and irreversible
9, time stamp
time stamp refers to the string or encoding information used to identify the recorded time and date. The international standard is ISO 8601
Turing completion refers to the ability of a machine to perform calculations that any other programmable computer can perform DAPP decentralized application is an open source application that runs automatically, stores its data on the blockchain, motivates it in the form of cryptocurrency token, and operates with protocols showing valuable proof Dao, a decentralized autonomous organization, can be regarded as a company that operates without any human intervention and gives all forms of control to a set of unbreakable business rules13. Privatekey - private key
a private key is a string of data that allows you to access a token in a specific wallet. As cryptocurrency, they are hidden except for the owner of the address
14. Publickey -- public key
is paired with private key. The public key can calculate the address of the currency, so it can be used as a certificate to own the address of the currency
15, miner
try to create a block and add it to the computing device or software on the blockchain. In a blockchain network, when a new effective block is created, the system will automatically give the block creator (miner) a certain number of tokens as a reward
16. The mine pool is a fully automatic mining platform, which enables mining machines to contribute their computing power to mine together to create blocks, obtain block rewards, and distribute profits according to the proportion of computing power contribution (that is, mining machines access the mine pool - provide computing power - obtain income)
17, public chain
fully open blockchain, refers to anyone can read, anyone can send transactions and transactions can be effectively confirmed, people all over the world can participate in system maintenance, anyone can read and write data through transactions or mining
18. Private chain
write permission is only for the blockchain of a certain organization or a specific few objects. Read permission can be open to the outside world or restricted to any extent
19, alliance chain
consensus mechanism is a blockchain jointly controlled by several designated institutions
20, side chain
wedged side chains technology, which will realize the transfer of bitcoin and other digital assets between multiple blockchains, which means that users can access the new cryptocurrency system when they use their existing assets
21, cross chain technology
cross chain technology can be understood as a bridge connecting the blockchains, and its main application is to realize atom transaction, asset conversion, information exchange within the blockchain, or solve Oracle problems among the blockchains
22. The hard fork
blockchain has permanent divergence. After the release of the new consensus rules, some nodes that have not been upgraded cannot verify the blocks proced by the upgraded nodes, and usually the hard fork will occur
23, soft forking
when the new consensus rules are released, nodes that have not been upgraded will proce illegal blocks because they do not know the new consensus rules, which will lead to temporary forking
24, hash -- hash value
generally translated as "hash", but also directly transliterated as "hash". In short, it is a function that compresses messages of any length to a message digest of a fixed length
25, main chain
the word "main chain" comes from the main network (, relative to the test network), that is, the officially online and independent blockchain network
for those who don't know the "jargon" in the currency circle, let's learn it as soon as possible:
1. What is legal currency legal currency is legal tender, which is issued by the state and the government. It is only guaranteed by the government credit, such as RMB, US dollar and so on 2. What is a token token, usually translated into token. Token is one of the important concepts in blockchain. Its more well-known name is "token". However, in the view of professional "chain circle" people, its more accurate translation is "token", which represents a proof of rights and interests on the blockchain, rather than currency token one is digital proof of rights and interests, which must be in the form of digital certificate of rights and interests, representing a right, an inherent and intrinsic value
3. What is warehouse building
the establishment of a position in a currency circle is also called opening a position, which refers to a trader's new purchase or sale of a certain amount of digital currency
What is Sohasuoha refers to investing all the principal

It is a kind of momentum and publicity of the project itself by the issuers of virtual currency projects
breaking refers to falling below, and issuing refers to the issuing price of digital currency. Broken currency circle refers to the price of a digital currency falling below the issue price
What is private placementprivate placement is a way to invest in cryptocurrency projects, and it is also the best way for cryptocurrency project founders to raise funds for platform operation
What do you think of the K-line diagram
K-line chart is also called candle chart, Japanese line, yin-yang line, bar line, red and black line, etc., commonly referred to as "K-line". It is based on the opening price, the highest price, the lowest price and the closing price of each analysis cycle
What is hedging
General hedging refers to two transactions which are related to the market, opposite in direction, equal in quantity and balanced in profit and loss. In the futures contract market, buy the same number of positions with different directions. When the direction is determined, close out the positions in the opposite direction and keep the positive direction to make profits
What is the positionposition is a kind of market agreement, which promises the initial position of the sale and purchase contract, and the buyer is long and in the expected position; The selling contract is short and in the expected position

Digital money (electronic money or electronic currency) is a kind of money in digital form (different from paper money and coins)
it shows properties similar to physical currency, but it can allow real-time transaction and borderless ownership transfer. Examples include virtual currency, cryptocurrency and currency issued by central bank and recorded in computer database (including digital base currency)
like traditional currencies, these currencies may be used to purchase physical goods and services, but they may also be restricted in some communities, such as online games
digital currency is the currency balance that is electronically recorded on stored value cards or other devices. Another form of electronic currency is network currency, which allows value transfer on computer network, especially on the Internet. E-money is also a creditor's right to other financial institutions such as private banks or bank deposits
digital money can be centralized, that is, it has a central point to control the money supply, or it can be decentralized, that is, the control power can have different sources
Digital currency is a general term used to describe all forms of electronic currency, whether it is virtual currency or cryptocurrency. It is a form of data expression of value. Through data transaction, it plays the functions of transaction medium, accounting unit and value storage, but it is not the legal currency of any country or region
the concept of digital currency was first put forward in 1983. They only exist in digital or electronic form. Different from the actual paper money or coins, they are invisible. They can only be owned and used on the Internet through e-wallet or designated network. The advantage of digital currency is that there is no bank, the transaction is instant, and the transaction cost is very low. So: coin, token and virtual currency belong to digital currency
the main characteristics of digital currency
1. In terms of payment and settlement, it does not rely on institutions. It is a publicly accessible digital general ledger maintained by the whole distributed network, which is called "blockchain"
2. In terms of issuance and proction, the essence is to keep accounts on a mutually verified public accounting system. Under a certain algorithm mode, find out a string of random codes that meet the conditions, and then package this string of codes with other transaction information into a block and record them in this account book, so as to obtain a certain amount of digital currency
(3) it has no national boundaries, which makes it flow around the world. Virtual world corresponds to the real world, through the exchange relationship between digital currency and traditional currency, under certain conditions, specific digital currency can buy physical goods, and traditional currency can also buy specific virtual goods In theory, its distributed general ledger system can prevent any participant from forging digital currency and rece transaction risk The lower transaction cost of digital currency will promote banks and other financial institutions to improve service level and rece transaction costs Digital currency and mobile financial business model can promote the development of Inclusive Financefor consumers, digital wallets are free and easy to get. For example, when a consumer makes a purchase on a merchant's website that has set up a server-side digital wallet, he enters his name, payment amount and delivery information into the merchant's own form. At the end of the purchase, he was asked to sign the user name and password for the wallet of his choice. Users can also get wallets from the wallet provider's site
although wallets are free for consumers, the suppliers charge the merchants for using wallets.
