Same algorithm as Ethereum
Ethereum is a new and open blockchain platform, which allows anyone to build and use decentralized applications running through blockchain technology in the platform. Like bitcoin, Ethereum is neither controlled nor owned by anyone - it's an open source project created by many people around the world
Different from bitcoin protocol, Ethereum is very flexible and adaptable. It's very easy to create new applications on the Ethereum platform. Anyone can use the applications on the platform safely 
Ethereum is a programmable blockchain. It does not give users a series of preset operations (such as bitcoin trading), but allows users to create complex operations according to their own wishes. In this way, it can be used as a platform for many types of decentralized blockchain applications, including but not limited to cryptocurrency
in a narrow sense, Ethereum refers to a series of protocols that define a decentralized application platform. The core of Ethereum is Ethereum virtual machine (EVM), which can encode any complex algorithm. In computer science terminology, Ethereum is "Turing complete.". Developers can use the existing JavaScript and python as the model of other friendly programming languages to create applications running on the Ethereum simulator
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"
this massive parallel operation throughout the Ethernet network is not to make the operation more efficient. In fact, this process makes computing on Ethereum slower and more expensive than on traditional computers. However, each Ethereum node runs Ethereum virtual machine in order to maintain the consistency of the whole blockchain. The consistency of decentralization makes Ethereum have high fault tolerance, zero downtime, and can keep the data stored on the blockchain unchanged and anti censorship
Ethereum platform has no characteristics and value. Like programming languages, it's up to entrepreneurs and developers to decide what to use. However, it is clear that some application types benefit more from the functions of Ethereum than others. Ethereum is especially suitable for those applications that automatically interact directly between points or promote group coordination activities across networks
for example, coordinate the application of point-to-point market, or the automation of complex financial contracts. Bitcoin enables indivials to exchange money without the help of financial institutions, banks or governments. The impact of Ethereum may be more profound
in theory, any complex financial activities or transactions can be automatically and reliably carried out on Ethereum with coding. In addition to financial applications, any application scenario with high requirements for trust, security and persistence, such as asset registration, voting, management and Internet of things, will be affected by Ethereum platform on a large scale
1. Litcoin (LTC) is an improved version of digital currency inspired by bitcoin (BTC). It was designed and implemented by a programmer who worked in Google. It was released on November 9, 2011. Lightcoin and bitcoin have the same implementation principle in technology, but the creation and transfer of lightcoin is based on an open source encryption protocol, which is not managed by any central organization
2. Sunshine coin (SSC for short) is sponsored by Liu Chunyang, vice president of Jinhua express delivery Association of Zhejiang Province, instrial entrepreneur and philanthropist of express delivery instry. As a legal person, Zhejiang Dongyang Yueyin Technology Co., Ltd. is registered with the formal instry and Commerce Bureau, with a registered capital of 10 million yuan. With this as the backing and support, the sunshine elite team affiliated to the company launched the first virtual coin sunshine coin
The English name of Vicat is onecoin, which is a kind of Internet virtual currency term created by the government and is suspected of pyramid selling fraudin 2017, CCTV announced the list of 350 fund pyramid schemes, with Vicat in the list
in May 2018, Zhuzhou County Procuratorate of Hunan Province prosecuted the last four suspects involved in the third batch of the "3.15" Vicat money online pyramid scheme case supervised by the Ministry of public security to the court
4. Amazon coin
Amazon announced in early February 2013 that it is expected to launch Amazon coins in the United States in May 2013. Amazon coins is a new virtual currency that allows U.S. users to buy apps, games and props in the kindle fire. Amazon will provide tens of millions of US dollars of Amazon coins at that time to let users try and consume the apps, games and props in the app on the kindle fire for free
5. Eth is a kind of digital token of Ethereum, which is regarded as "bitcoin version 2.0". It adopts the blockchain technology "Ethereum", which is different from bitcoin. It is an open-source public blockchain platform with intelligent contract results, and a resonance network composed of thousands of computers around the world. Developers need to pay eth to support the application. Like other digital currencies, ether currency can be bought and sold on the trading platform
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
although bitcoin and Ethernet are both digital currencies, unlike bitcoin, the main purpose of Ethernet is not to build itself as a payment substitute, but to facilitate and monetize the operation of Ethereum, so that developers can build and run distributed applications
bitcoin does not rely on specific currency institutions to issue. It is generated through a large number of calculations of specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction
bitcoin is very similar to cash
the advantages of bitcoin are: no freezing, no tracking, no taxes, and extremely low transaction costs. Compared with people who speculate in currency, it is wealth, and people outside the currency circle may think it is a fraud
bitcoin, Ethereum, bitcash, EOS, REBO, etc. are the mainstream digital currencies, which can be properly invested. All transactions have risks. You can invest cautiously. You can search online for fire coin, coin security, OK, dobby trading platforms, etc. all of which can trade bitcoin. These are relatively large trading platforms, investing in mainstream digital currencies, and Don't invest in counterfeit money or air money.
2) in terms of algorithm, the core algorithm sha256 adopted by bed and BTC has the same value attributes, but bed has established a new economic model through new technology development; Eth uses ethash algorithm
3) from the perspective of mining cost: BTC mining is becoming more and more difficult and has become an arena for mining equipment. At present, the latest 110t ant S19 Pro mining machine has adopted the latest 7Nm chip, and the price of the machine is nearly 20000 yuan. Some low computing power machines, such as the former king ant S9, can only be eliminated, resulting in a huge waste of resources; Eth uses graphics card GPU to mine, and the cost is also quite high; And bed can dig directly with the existing bitcoin miner or the obsolete bitcoin miner with low computing power, so the cost of miner is very low and the waste of resources is reced
4) from the perspective of total amount and upgrade space: the total amount of BTC is 21 million, and the current price is about ￥ 76000; The total amount of eth will reach 113 million, and the current price is about 2500 yuan; The total amount of bed and BTC is 21 million, and there is a huge space for upgrading.
