What about virtual currency delisting
In the middle of 2008, Ben Cong put forward the idea of bitcoin. In 2009, bitcoin was officially born. For more than 10 years, bitcoin has been appearing in the field of public investment. It is also praised by many people as a missed opportunity to get rich. However, from around 2014, many counterfeit digital currencies in the name of blockchain began to enter the capital investment market
generally speaking, the virtual digital currency trading market led by bitcoin is still a chaotic early dividend period market, so investors must be cautious in investment, and can not be blindly attracted by Shanzhai digital currency. In a word, it's impossible to drop the pie by nature. We must recognize our basic reality< br />
as the third largest bitcoin trading platform in the world in terms of trading volume, bitcoin China is the first of the three major bitcoin trading platforms in China to announce the cessation of trading business on the evening of September 13, China Internet Finance Association issued a risk warning, pointing out that bitcoin and other so-called "virtual currencies" lack a clear value basis, there is a strong speculative atmosphere in the market, the price fluctuates violently, investors blindly follow the trend of speculation, which is easy to cause capital losses, and investors need to strengthen their risk prevention awareness as soon as the ban came out, all localities responded. The Beijing rectification office under the Beijing Municipal Bureau of financial affairs immediately issued a document to coordinate with the clean-up and rectification of the ICO platform and immediately stop all kinds of ICO token issuance and promotion activities
Dag's full name is "directed acyclic graph". There is no block concept. Instead of packaging all data into blocks and linking blocks with blocks, each user can submit a data unit, which can contain many things, such as transactions, messages, etc. Data units are linked by reference relation to form DAG (directed acyclic graph) with partial order relation. The characteristic of DAG is to write data units asynchronously. A large number of wallet clients can write transaction data to DAG autonomously and asynchronously, which can support huge concurrency and high speed. At the same time, trustnote, which uses DAG technology, also supports declarative smart contracts. Declarative smart contracts mean that users can directly write and describe the results they want, and describe what they want to do in a very simple language that everyone can understand
by the end of 2017, there are more and more "high traffic applications". In addition to the mainstream e-commerce platforms, there are also live broadcast platforms, P2P financial management, today's headlines, Momo and so on. If "high traffic applications" are combined with DAG blockchain technology, what changes will it bring to the instry? In addition to the characteristics of the blockchain itself, such as decentralized, distributed ledger and tamper proof, DAG blockchain technology can not only support high concurrency, combine with double-layer consensus mechanism, use workload to prove consensus algorithm, but also prevent the "double flower" problem
then, how can DAG support high concurrency? First, the data is not as strong synchronization as bitcoin and Ethereum, but weak synchronization, allowing nodes to have different data at the same time, and the data can have some small differences. Second, the transaction can be confirmed through the reference between data units, that is, the subsequent units refer to the previous units. In this way, we don't need to transfer the data to the miners, and the whole process is completed by ourselves. This process is very fast. Dag is a beautiful way to solve the problem of high concurrency. Compared with the previous lightning network, DAG has its inherent advantages in other aspects
let's see how DAG can prevent "double flower"? If you can select a mainchain in a directed graph, you will find that all the nodes in the graph can be sorted in one way. If you connect the serial numbers in a row, the graph will become the same sequence structure as a blockchain, that is, the nodes that are sorted out, and each node is a transaction, not a block. Therefore, the determination of the main chain, through the main chain, can form a total order. The final result is that in a certain logical state, the transactions are sorted, which is the most critical part of DAG
"high traffic application" is a smooth expansion with the increase of the number of nodes and transactions. When the number of nodes exceeds 100 million or the number of transactions exceeds 1 million, the DAG's characteristic is that the more transactions, the faster, the more nodes
bitcoin is not the same. Bitcoin is a consensus network, contributing to 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.
to purchase virtual currency, it is recommended to purchase it from mainstream platforms, such as five bitcoin trading platforms, Xigu digital asset trading platform, Qianjin card trading platform, bitage trading platform, etc.
