How big is the current Ethereum blockchain
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"
Ethereum is the next generation of cryptography ledger. It intends to support many advanced functions, including user issuing currency, intelligent protocol, decentralized transaction and what we think is the first fully decentralized autonomous organization (Daos) or decentralized autonomous company (DACS) application
Ethereum does not specifically support every single type of function as a feature. On the contrary, Ethereum includes a built-in Turing complete scripting language, which allows you to write code for the feature you want to implement through a mechanism called "contract". A contract is like an automatic agent. Every time a transaction is received, the contract will run a specific code, which can modify the data storage inside the contract or send the transaction. Advanced contracts can even modify their own code
Ethereum was launched on November 1, 2015, and launched on August 22, 2016 on bitcoin trading platform, a well-known domestic trading platform; 30-¥ About 60, current: ¥ 1259.97, the rise is amazing
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
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.
