Ethereum leader

bitcoin uses SHA-256 encryption algorithm. When mining, it competes with computing power. In order to improve computing power, bitcoin has gone through four stages: CPU mining, GPU mining, FPGA mining and now ASIC mining machine mining, and the degree of specialization is getting higher and higher

Ethereum uses the ethash encryption algorithm. In the process of mining, it needs to read the memory and store the DAG file. Because the bandwidth of each read memory is limited, and the existing computer technology is difficult to have a qualitative breakthrough in this problem, so no matter how to improve the computing efficiency of the computer, the memory read efficiency will not be greatly improved. Therefore, in a sense, Ethereum's ethash encryption algorithm is ASIC resistant.

different encryption algorithms lead to great differences in mining equipment and computing power between bitcoin and Ethereum

at present, bitcoin mining equipment is mainly ASIC mining machine with a very high degree of specialization. The maximum computing power of a single mining machine is 110t / s, and the scale of computing power of the whole network is more than 120eh / s

the main mining equipment of Ethereum is video card miner, and there are very few specialized ASIC miner. On the one hand, the "ASIC resistance" of Ethereum mining algorithm improves the threshold of developing ASIC miner. On the other hand, after Ethereum is upgraded to 2.0, the consensus mechanism will be transformed into POS, and the miner can not continue mining

compared with the ASIC miner, the graphics card miner has two orders of magnitude difference in computing power. At present, the computing power of mainstream graphics card miner (8 cards) is about 420mh / s, and that of Ethereum is about 230th / s.

from the time dimension of the past two years, bitcoin's computing power of the whole network is growing rapidly, while Ethereum's computing power of the whole network is growing relatively slowly

The ASIC mining machine of

bitcoin is monopolized by several major mining machine manufacturers, and miners can only buy it from the market; Although the graphics card miner of Ethereum is also manufactured by a special miner, the miner can buy accessories from the market and assemble them according to his own demand

4. At 5 o'clock this morning, when we were still sleeping, bitcoin rose sharply to US $5300, accompanied by the rapid rise of the leading currencies. After the rapid rise, bitcoin fell sharply. When it fell to US $4700, it quickly returned to US $4900-5000 and stabilized, then the leading currencies also followed bitcoin.

Blockchain platforms include Ethereum, Asch and other underlying application development platforms

Ethereum, an open source public blockchain platform with smart contract function, provides decentralized Ethereum virtual machine to process point-to-point contract through its special cryptocurrency ether (ETH)

arch, a decentralized application platform based on side chain technology. Asch is designed to lower the threshold of developers, such as using JavaScript as the application programming language and supporting relational database to store transaction data, which is believed to be very attractive to developers and small and medium-sized enterprises

extended data

in 2008, Nakamoto first proposed the concept of blockchain. In the following years, blockchain has become the core component of electronic currency bitcoin: public account book for all transactions

by using peer-to-peer network and distributed timestamp server, the blockchain database can be managed independently. The blockchain invented for bitcoin makes it the first digital currency to solve the problem of repeated consumption. Bitcoin's design is a source of inspiration for other applications

bitcoin is the absolute mainstream of digital currency, and digital currency is in full bloom. Bitcoin, litecoin, dogecoin, dashcoin are common. In addition to currency application, there are various derivative applications, such as Ethereum, Asch and other underlying application development platforms, as well as NXT, SIA, bitstocks, maidsafe, ripple and other instrial applications

6. Blockchain (English: blockchain or blockchain) is a kind of distributed database, originated from bitcoin. The concept was put forward in the white paper of Nakamoto Tsung. Blockchain is an underlying technology of bitcoin, and bitcoin is only an application of blockchain
as we all know, bitcoin can realize point-to-point value transmission. In addition to bitcoin blockchain, there are many other blockchains, such as Ethereum blockchain. Therefore, we should distinguish the concepts of bitcoin, bitcoin blockchain, blockchain and blockchain technology
blockchain, which is first accompanied by the emergence of digital currency, has recently been widely discussed in the instry for its subversive impact on the existing financial field, and is known as a new round of change after the Internet technology revolution. As a distributed general ledger, this technology will first break out a huge force of change in the financial field: clearing, settlement, remittance, payment, value transmission, innovation and inclusive of the whole financial network, including all income groups, connecting regions and people separated by physical borders, and reshaping the whole economy and society
because blockchain is an open, transparent, traceable and tamper proof distributed general ledger system, blockchain technology can effectively rece the error rate of payment, clearing and settlement steps, and monitor the inflow and outflow of funds in each step, which is an effective means to promote the establishment of an honest society. Therefore, if the regulatory authorities can effectively use this technology, it will help to control the asset status and possible risks of the financial instry
China's blockchain enterprises continue to emerge
since 2015, China's attention and Research on blockchain technology has graally expanded
from the perspective of government departments, Zhou Xiaochuan, governor of the central bank, pointed out in February 2016 that digital currency must be issued by the central bank, and blockchain is an optional technology. Prior to that, the people's Bank of China also held a seminar on digital currency. In addition to the central bank, Zhejiang Province, Beijing and other relevant government departments also expressed their support for blockchain application research last year
from the perspective of enterprises, Wanxiang Group has established a blockchain laboratory, and many blockchain innovation and entrepreneurship enterprises continue to emerge< In addition, a number of instry alliances are being established. In December 2015, blockchain research alliance and blockchain Application Research Center were established; In February 2016, Zhongguancun blockchain instry alliance was established; In April, China ledger officially announced its establishment in Beijing<
blockchain concept stocks become the wind outlet
blockchain is like a database ledger, recording all transaction records. Because of its safety and convenience, this technology has graally attracted the attention of the banking and financial instry. According to the survey report of the world economic forum, it is predicted that by 2025, 10% of the relevant information in the global GDP will be preserved by blockchain technology. Blockchain technology is facing a blue ocean, and related concept stocks are becoming the wind. In A-share listed companies, it is suggested to focus on the concept leading stocks: Feitian integrity, Yuyin shares. In the future, with the fermentation of speculation, other concept stocks are expected to follow suit
according to the analysis of wind information, the brief comments of blockchain concept stocks are as follows:

10. What is the relationship between chip and semiconctor? In short, semiconctors are materials, and chips are applications of semiconctors. From the perspective of instrial chain, it should be like this

semiconctors are divided into three categories: semiconctor material support, semiconctor material manufacturing and semiconctor material application<

semiconctor materials proce semiconctor components, which can be divided into four categories: integrated circuits, discrete devices, sensors and optoelectronics. Chip is the proct of integrated circuits, and chip, integrated circuit, IC and chip all refer to the same thing

chip classification chips can be classified from many aspects: 1. Processing signal classification: analog signal chip, digital signal chip 2. Application scenario classification: civil level, instrial level, automotive level, military level, aerospace level PS: each level has different requirements in circuit design, process processing and system cost 3.
