Real blockchain
At present, whether a digital currency is a valuable currency basically belongs to the "angel wheel" stage. There are three criteria to determine whether a digital currency is a valuable currency: one is the team, the other is the economic model, and the third is the instry demand
The randomness of theteam is too great, so we will not discuss it here. This paper first makes a detailed analysis of the economic model of digital currency. In the following article, the author will analyze some digital currencies according to different instries
Strictly speaking, the economic model involved in this paper is not completely equivalent to the concept described in economics. Especially in digital currency, currency consensus mechanism and incentive mechanism Consensus mechanism is the strategy and method for each node in the blockchain system to reach an agreement, which should be selected flexibly according to the different types of system and application scenarioscommon consensus mechanisms include pow, POS, dpos, pbft (and its variants), etc. In addition, based on the different application scenarios of blockchain technology and the characteristics of various consensus mechanisms, this paper evaluates the technical level of various consensus mechanisms according to the following dimensions:
A) compliance supervision: whether super permission nodes are supported to supervise the nodes and data of the whole network
b) performance efficiency: the efficiency of reaching a consensus and being confirmed
Resource consumption: CPU, network input and output, storage and other computer resources consumed in the process of consensusd) fault tolerance: the ability to prevent attacks and fraud
1 instry background
looking for Instry pain points: asset management needs professional team and knowledge, but now most digital currency investors do not have it; The fluctuation of digital money market is huge, and investors can't keep the value of assets in the falling market
2 own advantages
in the stock and futures markets for many years, has a mature and high-quality asset management team; AI big data team has strong technical strength
3 Market Research
after market research, it is estimated that the market value of asset management will be about US $1 billion in the next five years
4 total amount of digital currency
after considering the expected asset management market value, development cycle and difficulty, we will consider issuing 2 billion pieces of XT based on Ethereum erc20 digital currency, and never issue additional ones
5 allocation method
early stage investors hold 10%, teams hold 20%, business operation 10%, community construction 10%, and investors hold 50%
6 digital currency release / repo mechanism
the release mechanism can be divided into three categories:
the first category: the money holding part of business operation is fully unlocked, and the purpose is limited to business and operation activities
the second type: the release mechanism of community construction is that community members release exclusive information, cooperation platform release exclusive project progress and so on. According to the number of participating IDS, the corresponding proportion of XT is released (publishers and participants get 50% each) until all the releases are completed (after the release, the follow-up reward comes from the platform profit pool)
the third category: investors hold the mainstream digital currency, conct asset management in the platform, release a certain amount of XT according to the exchange ratio, and the early investors and the team hold part of it synchronously and unlock it according to the proportion
the repo mechanism is: 50% of the profit (in XT) will be returned to the holder; The rest goes into the platform profit pool, and 50% of XT in the profit pool is destroyed monthly until the total number of XT is 1 billion; The rest will be used as platform ecological construction fund
7 digital currency equity
profit sharing: holding XT is for platform users, and they can enjoy 50% of platform profits
platform Governance: participating in platform activities, enjoying XT awards and airdrop activities of other project parties
function customization: Based on platform AI big data, investors can purchase services optimized for indivial trading strategies
blockchain technology has three obvious characteristics: openness, security and uniqueness
openness mainly refers to that the stored information in the blockchain is completely open to all participants. This is mainly determined by the point-to-point network storage mode of the blockchain. In the blockchain network, each node can store a of the blockchain, and the uniqueness of the blockchain can ensure that the is exactly the same between different nodes
security mainly refers to that the information stored in the blockchain block is saved after being processed by digital encryption technology, and only the private key holder can decrypt the information to obtain the real information. Other members can only see and verify the integrity and uniqueness of information, but cannot see the real information
uniqueness is mainly e to the fact that the information on the blockchain cannot be tampered with once it is on the chain, so it is unique. Of course, the uniqueness here also includes the uniqueness in space, that is, all nodes have only one version of information, and also includes the uniqueness in time, that is, the historical data cannot be changed. This uniqueness also means that the blockchain maintains the characteristics of a unique main chain in the process of operation, and once other chains appear, it is a bifurcation. The emergence of bifurcation will lead to the plication of blockchain in two different spatial dimensions. Of course, to solve this problem, we need to set reasonable consensus rules to avoid
the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry.
Blockchain technology is a new distributed infrastructure and computing paradigm, which uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses intelligent contract composed of automated script code to program and operate data. In short, in the blockchain system, the transaction data generated by each participant will be packaged into a data block after a period of time. The data blocks are arranged in chronological order to form a chain of data blocks. Each participant has the same data chain and cannot be tampered unilaterally, Any modification of information can only be carried out with the agreement of the agreed proportion of subjects, and only new information can be added, and the old information cannot be deleted or modified, so as to realize the information sharing and consistent decision-making among multiple subjects, and ensure that the identity of each subject and the transaction information between subjects can not be tampered with, open and transparent
the technical commonness of blockchain projects: block, account, smart contract and consensus, which constitute the general model of the current blockchain system
today, I want to tell you what is a real dragon ball for blockchain application landing and enabling traditional commerce and trade
first of all, dragon ball technology will develop the electronic business platform integration asset plan, and the cable asset payment facility will serve the upcoming block chain business application landing wave. In the future, valuable assets can be applied to all aspects like WeChat payment and Alipay, which will bring convenience to people's payment and life, and at the same time, increase sales to businesses. This is the commercial value brought by Longzhu. Based on Singapore, the Longzhu foundation in Singapore will radiate the world and aspire to become the leader of new asset technology and contribute to the circulation of global commodity trade
at present, the number of domestic blockchain related companies is increasing, among which fast online has always been in the leading position
up to now, we have independently developed 100 + Internet financial procts and provided innovative suggestions and solutions based on our years of instry experience and advantages
as the development platform of blockchain, she only focuses on the innovation of blockchain technology and proct development. There is an overall personalized solution from research and consultation, project start-up to the final system launch and later maintenance upgrade.
The hottest things this year are "bitcoin", "Ethereum" and all kinds of cryptocurrencies, so hot that even aunts and uncles are about to start talking about them. It is no exaggeration to say that 2017 is the first year of the development of cryptocurrency and blockchain technology
as the underlying technology behind bitcoin, the concept of blockchain has only been mentioned in the past two or three years, although as early as 2009, "Nakamoto Tsung" released bitcoin. After this wave of digital currency boom, the concept of blockchain technology has really entered the eyes of all walks of life. I'm afraid it's too early to mention the wide application of blockchain technology, which is still in a very early stage of development. However, e to the arrival of the boom, many technicians and teams have contributed their efforts to build some blockchain concept projects“ Needless to say, as the first application of blockchain technology, bitcoin of "Zhongben cong" has realized the function of distributed ledger, which can realize the first decentralized value transmission of human beings. It can be said that it is "blockchain 1.0". Then Ethereum invented the smart contract, which extended the function of blockchain technology to build applications. It is well deserved to be defined as "blockchain 2.0". However, the blockchain concept projects that came out later did not realize this leap forward role, but only improved to a certain extent at the application level, so they can not be called "blockchain 3.0"
so what is "blockchain 3.0"? Maybe bitcoin OS is the answer: an operation system that is completely based on blockchain technology and follows the concept of blockchain technology. In the 1980s, before Microsoft released the windows operating system, personal computers and Internet technology were still in a non systematic state and could not be popularized. After the release, personal computers were allowed to enter ordinary people's homes, making PC and Internet universal application procts. Recently, bitcoin OS team announced the implementation of the bifurcations of bitcoin and Ethereum on Christmas day, so as to officially publish the plan of developing blockchain OS
anyone who knows a little bit about blockchain technology knows that bitcoin solves the problem of account book, while Ethereum is a smart contract to realize application expansion. Later, a team will launch a distributed storage project. But these systems with only a single functional mole are not "operating systems". The traditional definition of operating system is a huge management and control program, which includes five management functions: process and processor management, job management, storage management, device management and file management. In fact, the OS based on blockchain does not need to change all the five functional blocks into distributed ones, as long as the parts related to the external transmission of value and information can be decentralized and distributed. Therefore, the blockchain operating system should have at least three functions of "account system management, computing resource management and storage resource management", which can realize distributed ledger, edge computing and edge storage. Although it is still too early to define the instry standard in this way, bitcoin OS team is committed to realizing the blockchain OS possessed by these three functional blocks first, and then improving it through iteration
according to the bitcoin OS team, the name "bitcoin OS" is actually "blockchain OS", which is named after "bitcoin", which is also a tribute to the inventor "Satoshi Nakamoto". At present, from the technical details given by the bitcoin OS team, we may be able to see some aspects of this "blockchain 3.0" project
firstly, the management function of the account book system supports locating the ownership of resources according to the account ID, such as the private key; Computing resource management can obtain corresponding computing resources according to the demand, support edge computing, and share distributed computing power. In addition, storage resource management can use storage resources according to the demand, and support edge storage. Compared with bitcoin OS, Ethereum only supports account system and smart contract, which can not meet the distribution of distributed computing tasks. Ethereum only supports the fair execution of contract code, let alone the management of storage resources. So Ethereum is only a custom calculator
in addition, it is worth mentioning that bitcoin OS self customized enhanced smart contract. It supports two modes, which are more flexible and efficient
1. Central computing mode: the outgoing node is responsible for executing the smart contract, and both the incoming parameters and the output results support sipfs to be stored in the storage node
Distributed computing mode: ordinary nodes can claim computing tasks, input parameters and output results support sipfs storage to storage nodesfinally, we also need to mention the built-in sipfs super interstellar file system of bitcoin OS. Sipfs can realize the decentralized storage of technical input parameters and output parameters. At the same time, the file has a life cycle, and the DNA description of the file descriptor is recorded on the blockchain. The file descriptor of sipfs does not exist on the blockchain, but it will be stored in a separate file descriptor data file. After the end of the file life cycle, the blockchain will automatically delete the file descriptor, Realize the intelligent slimming of blockchain
"blockchain 3.0" is worth looking forward to, and bitcoin OS team, as the vanguard, is worth paying attention to and encouraging. We are looking forward to the real blockchain operating system
on the ground, there will be different solutions according to different instry needs
for example, in the financial instry, relevant financial technology companies have studied and applied it for a long time. Recently, there is a one account chain platform, which is released by Ping An's financial one account link company. It is the solution of blockchain in the financial instry. According to the introction, it has broken through the bottleneck in the implementation process.
1. Bitcoin by watching video
coinbase, a bitcoin exchange in the United States, launched a project called "coinbase earn" two years ago. You can get various digital currencies by watching some blockchain or bitcoin knowledge videos, and then answering some multiple choice questions. This kind of virtual currency is similar to collecting wool and can earn hundreds of dollars in general. But you have to register as a user first
2. Bitcoin loans earn interest
if you already have some bitcoin, you can earn bitcoin interest by borrowing. You are like a bank, lending your bitcoin to another person at a certain interest rate. Because the market is not regulated, interest rates are usually much higher than standard bank rates, which means there is potential for high returns. But there are also risks. What if the other party doesn't pay you back? Therefore, we need to choose some third-party P2P intermediary platforms to borrow, such as blockfi, NEXO, btcjam, bitbond, etc
3. Get bitcoin by doing tasks
everyone has more or less come into contact with some online earning platforms. You can register an account on the online earning platform, and then do some small tasks to get a few cents' income. These tasks include registering an app account, downloading an app, and so on. Bitcoin can also be obtained by doing tasks, which is the simplest way to get bitcoin. That is to say, the revenue from bitcoin is not much, and it is time-consuming
4. Take bitcoin for watching ads
some websites encourage users to watch ads or click on ads, and then pay users bitcoin as a reward. In fact, this is also a task of the nature of the site, your task is to go to other sites to see advertising or click advertising. At present, the well-known task publishing platform is ads4btc, which allows users to watch ads for 5 seconds, 10 seconds or 20 seconds, and then users earn bitcoin rewards
but the reward is very low. According to the price offered by ads4btc, if you watch ads all day, the income will not exceed $10, so it may not be a feasible choice for most people. Unless there is a cheating machine, it can replace you in advertising
5. Bitcoin faucet
bitcoin faucet is the most popular way to collect wool in coin circle. In December 2010, in order to let more people know and try to use bitcoin, Gavin andresson, member of bitcoin core development team, bought 10000 bitcoins for $50 and created a website called "bitcoin faucet". At that time, as long as you visit this website, you can get five bitcoins for free, which was worth about 5 cents at that time. This has a significant effect on people's acceptance of bitcoin
1. Purchase on the trading platform or conct third-party guaranteed transactions
2. You can exchange your own goods or services for bitcoin
3. Join the army of bitcoin mining and become a miner to mine bitcoin
let's popularize the common sense of bitcoin:
bitcoin is a consensus network, which promotes a new payment system and a fully digital currency. It is the first decentralized peer-to-peer payment network, which is controlled by its users without a central management organization or middleman. From the user's point of view, bitcoin is much like Internet cash. Bitcoin can also be regarded as the most outstanding three style bookkeeping system
mining is a process of consuming computing resources to process transactions, ensuring network security and keeping everyone's information synchronized in the network. It can be understood as the data center of bitcoin. The difference lies in its completely decentralized design. Miners operate all over the world, and no one can control the network. This process is called "mining" because it is similar to gold panning, because it is also a temporary mechanism for issuing new bitcoin. However, unlike gold panning, bitcoin mining provides rewards for services that ensure the safe operation of payment networks. After the last bitcoin, mining is still necessary.
