The relationship between blockchain and everyone
what is Ethereum:
Ethereum is an innovation based on the application of technologies and concepts in bitcoin to computers. Ethereum itself imitates a lot of bitcoin technology to maintain the computer platform. blockchain technology is one of them
Ethereum platform can safely run any program users want
advantages of Ethereum over other competitive currencies before Ethereum appeared, some digital currencies imitated bitcoin. However, these projects have their own shortcomings, they can only support one or several specific applications at the same time< However, the reason why Ethereum can surpass the limitations of these projects in the past is because of the core idea of Ethereum
what Ethereum wants to implement is a blockchain protocol with built-in programming language. Since it supports programming language, in theory, any blockchain application can be defined with this language, and then run on Ethereum's blockchain protocol as an application
The design of Ethereum is very flexible and adaptable
Ethereum target sets the advantages of blockchain technology, in order to add the advantages of blockchain, such as decentralization, openness and security, to almost all computing fields
blockchain applications of Ethereum
Ethereum has many blockchain applications, such as digital applications of gold and stocks, financial derivatives applications, DNS and digital authentication, etc
Ethereum has achieved more than 100 blockchain applications by many start-ups
Ethereum has also been closely watched by some financial institutions, banking consortia (such as R3), as well as large companies like Samsung, Deloitte, RWE and IBM. As a result, a number of blockchain applications such as simplified and automated financial transactions, merchant loyalty index tracking, and gift cards designed to achieve decentralization of electronic transactions have emerged
the relationship between Ethereum and blockchain:
Ethereum is a programmable blockchain
Ethereum does not give users a series of preset operations (such as bitcoin transaction), but allows users to create complex operations according to their own wishes
in this way, Ethereum can be used as a platform for various types of decentralized blockchain applications, including but not limited to cryptocurrency
like other blockchains, Ethereum also has a peer-to-peer network protocol. Ethereum blockchain database is maintained and updated by many nodes connected to the network. Each network node runs the Ethereum simulator and executes the same instructions. Therefore, people sometimes call Ethereum "world computer"
Blockchain technology has been popular since its birth. For the general public, it seems to be very close to us, but we don't know what it (blockchain) is; In fact, the blockchain instry, which is still in the early stage of development, is in chaos both from the technical level and from the content level
What is blockchainblockchain is a technical solution to maintain a reliable database collectively through centralization and distrust. In short, blockchain technology is like a nationwide accounting method. There is a database behind all the systems. You can think of the database as a big ledger. When the data changes, everyone in the system can make bookkeeping, and the fastest and best bookkeeping person will be written into the account book and sent to other people to complete the update of the account book. This way, we call it blockchain technology
, for example, in the payment behavior, there should be third parties involved in any transfer before, for example, the third party organizations such as banks or Alipay, and the block chain technology can effectively solve the intermediary credit problem, so that two people who are not acquainted with each other can complete the transfer directly without the third party. p>
2. What are the advantages of such a nationwide bookkeeping blockchain
knowing what a blockchain is, it is not difficult for us to find that although the efficiency of blockchain is sacrificed, the security is greatly guaranteed. First, the system can hardly be destroyed; second, the accounting process is open and transparent, and cheating is impossible; Third, the cost is greatly reced, and the efficiency is relatively higher
Is blockchain software? What program is it written inperhaps through the above introction, some people will ask, is blockchain a specific software? Actually, it's not. Blockchain is like a database. It's a design idea of a specific technology. It can be implemented in most languages, and in many ways
having said so much, you should know what blockchain is. In fact, blockchain has little to do with the ordinary people born in the 90s. We just need to enjoy the convenient services brought by the Internet or cloud services, unless you want to take blockchain as a business. At present, blockchain technology is still developing rapidly, and its design idea is relatively simple, Maybe it will become more complicated in the future
blockchain technology is not only the underlying technology of bitcoin, but also the core and infrastructure of bitcoin bitcoin has been running without any centralized organization operation and management. Later, bitcoin technology was abstracted, which was called blockchain technology or distributed ledger technology
extended data:
disadvantages of blockchain technology applied to digital currency:
first, there is no circulation management organization for "decentralization" blockchain technology is essentially a distributed database system with one-way linked list logic structure and P2P network design mode, which determines that there is no unified central control system for virtual currency based on blockchain technology
Second, it is difficult to effectively control the quantity supply the circulation of virtual currency based on blockchain technology is fixed, and according to Fisher Equation, the total transaction volume of the whole society under a certain price level in a certain period has a certain proportion with the required nominal currency volume, while the constant currency volume obviously can not meet the requirements of the growing total price of social goods Thirdly, "mining mechanism" is difficult to create recognized value bitcoin itself has no value and no national credit support. Some people think that "by continuously consuming computing power and energy to inject value into virtual currency", but it is obviously not the most efficient choice to consume millions of calculations in order to find a hash value that meets the requirements Fourthly, procers and early holders are easy to get high seigniorage any virtual currency based on blockchain technology is held by a few people at the initial stage of its development. Take bitcoin as an example. At first, bitcoin was only a proct of a few people's game. The first bitcoin purchase in May 2010 was $10000 BTC's purchase of $25 pizza. The first bitcoin transaction completed in July of the same year was $0.04/btcblockchain is essentially a distributed ledger database, it is a series of data blocks generated by cryptography Association, and each data block contains effective confirmation information of multiple bitcoin network transactions
Statistics show that in 2017, China's e-invoice circulation reached 1.31 billion, and it is expected to reach 54.55 billion by 2022, maintaining an average annual growth rate of more than 100%. Recently, when talking about blockchain invoice, people's daily stressed that electronic invoice should be added with "lock", and blockchain's open consensus, decentralization, non tampering, distributed consistency and privacy protection are the "lock" of electronic invoicefinally, I repeat my idea: blockchain gives us freedom, and freedom will bring a lot of innovation. Innovation will eventually bring us wealth. I believe blockchain will have a similar development path. The core task of blockchain is to stabilize the value, establish a trust system with almost zero cost, and release the energy of indivials in pursuit of wealth preservation and appreciation
if 50 points = 50W, then 1 point = 1.48, 50 points = 4.4: the larger the purchase points, the more 1 point card = mhblt.6w
if 50 points = 35W, then 1 point = 0
give you a range. 7W
if 50 points = 40W, then 1 point = 0:1 hour = 38 cents, Netease point card discount 9.0w
if 50 points = 55W, then 1 point = 1, is close to 38 cents an hour.79, give the most satisfied< If 50 points = 25W, then 1 point = 0.2W
note: if 50 points = 60W, then 1 point = 1:
if 50 points = 20W, then 1 point = 0 The free time of buying some cards is not included
, you can't say that 100 points is probably not 100W; 4) If 50 points = 45W, then 1 point = 0, 47.1w
if 50 points = 60W, then 1 point = 1 It depends on the percentage of points in your district 5 W
if 50 points = 30 W, then 1 point = 0.74 yuan, which is the same area in popular terms
if 50 points = 50 W! Hope
