Why does the blockchain use Ethereum
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"
although the pow mining mechanism is adopted, the block out mechanism of Ethereum is different from that of bitcoin. Due to the short block time of Ethereum, Ethereum is easy to form isolated blocks. Isolated blocks refer to the blocks that are not on the longest chain. Bitcoin's isolated blocks have no block rewards, but in Ethereum, isolated blocks can be referenced. The referenced isolated blocks are called "Uncle blocks", and their packaged data will also be recorded in the blockchain. Unlike bitcoin, Ethereum's TERT block has a reward, and each TERT block can get a reward of 4.375 Ethernet coins at most
Ethereum is a programmable and Turing complete blockchain development platform, which is equivalent to a decentralized global computer. In a programming system, there are usually some virtual machines to compile and execute. Java has JVM. In Ethereum, there is also Ethereum's virtual machine EVM, which can execute any complex algorithm code. Developers can use existing programming languages such as JavaScript or Python to create their own applications on Ethereum. Through Ethereum's virtual machine, you can easily issue digital assets, write smart contracts, set up and run decentralized applications, and set up decentralized autonomous organizations
eth is also known as the internal fuel of Ethereum. Unlike currency digital assets, Ethereum is not only used for transfer, but also for payment of smart contracts
in order to prevent the Ethereum blockchain from being full of junk contracts and junk applications, and to establish and run smart contracts on Ethereum, you must use eth to pay for smart contracts. For example, when you transfer your newly created digital assets on the Ethereum blockchain, you need to use eth to pay the handling fee instead of your newly created digital assets.
Blockchain 1.0 era usually refers to the development stage of blockchain application represented by bitcoin from 2009 to 2014. They are mainly committed to solving the problem of decentralization of currency and means of payment; After 2014, developers pay more and more attention to solve the technical and scalability problems of bitcoin. At the end of 2013, vitalik buterin released Ethereum white paper "Ethereum: next generation smart contract and decentralized application platform", which introced smart contract into blockchain and opened the application of blockchain outside the currency field, thus opening the era of blockchain 2.0< The so-called smart contract is actually a kind of computer contract that can be automatically executed based on prescribed trigger rules. It can also be regarded as a digital version of traditional contract. It was proposed by interdisciplinary legal scholar and cryptography researcher Nick Szabo more than 20 years ago. This technology was once not used in the actual instry because of the lack of programmable digital system and related technologies, until the emergence of blockchain technology and Ethereum provided a trusted execution environment for it
compared with bitcoin, Ethereum is a complete scripting language of Turing, which supports developers to create and publish arbitrary decentralized applications on the platform. Since its birth, there have been more than 200 decentralized applications based on Ethereum in the world
the chief researcher of bitwindow blockchain said: in the era of blockchain 2.0 represented by Ethereum, blockchain technology has graally expanded from the field of currency and payment to the field of finance. With the development of technology and the wider application of blockchain, the era of blockchain 3.0 beyond the monetary and financial fields will be around the corner. This article is excerpted from bitwindow. China's professional blockchain and digital currency instry analyzes the media, and adheres to a neutral, objective and dialectical attitude to understand and interpret the latest trends of blockchain and digital currency
In fact, Ethernet is an electronic virtual currency, which is regarded as "bitcoin version 2.0". The blockchain technology "Ethereum", which is different from bitcoin, is the real reason to win Putin's favor
Ethereum is an open-source public blockchain platform with smart contract function. It mainly provides decentralized virtual machine to process point-to-point contracts through its special encrypted currency Ethereum, which is fast and unlimited in quantity. In other words, it is a monetary payment system, but their functions and purposes are different
if bitcoin is considered to be a shared global book that securely records all bitcoin bills. Then Ethereum is to maintain a shared computing platform, which can flexibly and safely run any program users want. Because of this, many countries and enterprises are developing how to use Ethereum technology in the real world
the latest price of eth on btctrade platform of bitcoin trading network is ¥ 2430! The increase is amazing
blockchain Ethereum is widely used
at present, the application of Ethereum technology in Russia is still relatively positive. For example, veb, the state-owned Development Bank of Russia, began to apply Ethereum technology to some administrative functions last week, and Russian steel giants are also testing the application of Ethereum in the safe transfer of international letters of credit. Therefore, Putin believes that this virtual currency can help Russia diversify its economy and support the paving of the way by blockchain technology and the establishment of new businesses
not only Russia, JPMorgan Chase, Microsoft, Intel and others are optimistic about Ethereum technology. At the same time, Ethereum has also been paid close attention by some financial institutions, banking consortia, Samsung, IBM and other large companies, resulting in the simplification and automation of financial transactions, merchant loyalty index tracking, customer satisfaction index tracking, customer satisfaction index tracking, etc Blockchain applications such as gift cards are designed to achieve decentralization of electronic transactions. That's why the etheric currency is rising
the future of ether coin
of course, different from Ethernet, there are 670 bitcoin ATMs in the world, and thousands of outlets support bitcoin payment, but Ethernet has not yet emerged in the field of electronic payment. Mainly used to support the Ethereum network to run the program. Therefore, whether bitcoin will be recognized in the future is still unknown, but what Russian President Vladimir Putin has done may not be a signal
we have said before: it is still difficult to define bitcoin as currency, but it must be an asset, and I think Ethereum must be an asset. Although the application of blockchain technology is not yet mature, in a sense, it will be used sooner or later. After all, in the future era of big data, blockchain technology can better protect the efficiency and privacy of our information
this is why digital currency Ethereum is so popular
hope to adopt
since last year, a variety of digital currencies have emerged in an endless stream, and blockchain has also been on fire
many people are connected with blockchain as soon as they mention currency speculation; As soon as you hear that an enterprise is doing a blockchain, you will immediately ask if you want to issue money
it seems that blockchain is equivalent to digital currency, and the purpose of studying blockchain is to speculate in currency< br />

when you are new to blockchain or digital currency, it is reasonable to equate blockchain with currency speculation
after all, if it wasn't for the growing popularity of bitcoin, no one might have paid attention to blockchain technology so far. If it wasn't for more and more people investing in bitcoin, no institution would have issued a variety of other digital currencies
however, after in-depth understanding of blockchain and digital currency, we still think that blockchain is money speculation, so our understanding is really a bit biased
blockchain is the underlying technology of bitcoin. No matter bitcoin, Ethereum, lightcoin or other various tokens, they are all applications based on blockchain technology
but this does not mean that the blockchain can only be used to issue money, just like fish is raised in the water, but it can not be said that fish is water, and hairy crabs and crayfish can grow in the water
in addition to the various tokens we see at present, blockchain has a very broad application prospect

so what is a blockchain
to put it clearly, blockchain is: "blockchain is a kind of technical mole or encryption algorithm that is both basic application and top-level design. It breaks the barrier that an information is only saved by one central server or multiple services in the past, and copies the same information to more places at the same time, such as 1 million servers. Only when more than half of the stored information has been tampered with can chaos be caused. "
in a word, understand the relationship between bitcoin and blockchain:
blockchain is a technical concept born from bitcoin encryption technology
bitcoin is a kind of digital virtual currency, followed by the payment currency as a contribution to storage computing power
if you want to store the same information in countless servers, who will store it for free? There has to be a reward. Bitcoin is a reward for accepting free storage. This reward is a virtual thing called bitcoin.
blockchain 1.0 mainly refers to bitcoin. Blockchain 2.0 extends to all assets, while blockchain 3.0 goes beyond currency, finance, even commerce, and all areas of our lives, including politics, social relations, ecation, medical care, etc. According to the prediction and conception of people in the instry, the era of blockchain 3.0 will be realized in the next five years. At that time, blockchain will be recognized and accepted by all the public like the Internet, thus completely subverting our lives
McKinsey has submitted a technical report on blockchain to the Federal Insurance Advisory Committee of the United States. The report calls 2009-2016 the "Dark Age" and believes that all blockchain solutions ring this period are based on bitcoin, and the new era of blockchain will begin in 2016. At that time, the application of blockchain will become unprecedented. Applying an original sentence in McKinsey report: Based on the current development speed of blockchain, we believe that blockchain solutions may realize their full potential in the next five years.
