1. Based on the core idea of bitcoin network, ethereum project puts forward many innovative technical concepts, including smart contract, account based transaction, Ethereum and fuel.
2. Introction: Ethernet currency is the name of currency used in Ethereum, which is used for payment calculation in Ethereum virtual machine. Ethereum is a blockchain that can be used to deploy decentralized applications. It is an open source computer platform and blockchain platform. At the end of 2013, it was founded by vitalik buterin, a Russian programmer< Br > release time: 2014. At present, Ethernet is the second highest cryptocurrency in market value, second only to bitcoin< < br > circulation supply: 97524469eth (the total amount is not constant) < br > trading volume share: at present, it accounts for 19.5% of the cryptocurrency market< Br > market value: $85966171144 < br > Future Prospects: the value of Ethereum depends on whether the application on Ethereum platform is prosperous, and Ethereum may have the momentum of "taking over" bitcoin to continue to soar.
3. The term "difficulty" comes from bitcoin, the pioneer of blockchain technology, which is used to measure the average number of operations needed to dig out a block. mining is essentially solving a puzzle. Different e-coins set different puzzles. For example, bitcoin uses SHA-256, lightcoin uses script, and Ethereum uses ethash. All the possible values of the solution of a puzzle are called the solution space. Mining is to find a solution among these possible values

4. At the top of Ethereum is DAPP. It exchanges with the smart contract layer through Web3. JS. All smart contracts run on EVM (Ethereum virtual machine) and use RPC calls. Below EVM and RPC are the four core contents of Ethereum, including: blockchain, consensus algorithm, mining and network layer. Except DAPP, all other parts are in the Ethereum client. The most popular Ethereum client is geth (go Ethereum)
5. If this is only the most basic, it can be done by 100000 yuan. If you need to add other functions, it depends on the difficulty of the functions you add. If you want affordable price and good service, I suggest you consult Shengshi Huacai company. I've used it for two years, and almost no problems have occurred.
6. 1. What is the ether classic<
etc (Ethereum Classic) is a bifurcated currency that Ethereum hard bifurcates after 1920000 blocks, and its function is very similar to Ethereum. Etc adheres to the concept of decentralization and supports the consensus mechanism of blockchain guarantee. Etc firmly believes that once the blockchain starts to run, its development direction will not be controlled by any central team, but will be determined by the consensus of the people participating in the whole network and the consensus of the computing power of the whole network
the Ethereum blockchain hard branching in July 2016 aims to transfer the Dao funds stolen by hackers to an account controlled by investors, and let the old transaction records be forgotten by history. Most Ethereum developers are involved in the reversal, as are exchanges, startups and other members of the ecosystem. A few days later, the project returned to normal. But not everyone wants to forget the old record. As a result, a small number of miners continued to use the original blockchain as a protest. They described the hard fork as a capital withdrawal for the abandoned project of the Dao. So Ethereum classic (etc) was born
2. Detailed parameters
Chinese Name: Ethereum classic English Name: Ethereum classic English abbreviation: etc
developer: Ethereum Classic team core algorithm: ethash consensus proof: POW
release date: 2016 / 7 / 20 block time: About 15-17 seconds / block
total currency: fixed at 210 million, up to 230 million, Every 5 million blocks decelerate by 20%, and the first proction rection is expected to be in December 2017
main features: independent cryptocurrency

7. If you want to play with mainstream currency, cash or contract, you can make a lot of money with security and stability. Don't believe in the messy welfare, all kinds of routines, and pit the dead
8. Gas & gt; ethestimateGas({ from:ethaccounts [1], to: ethaccounts[2], value:50000000000000 }) 21001 > Ethgasprice 2000000000, as shown above, shows this account [1] = & gt; The transaction of account [2] needs 21001 gas, and the current gasprice is 2000000000. How many gas does it take to send transaction / call contract method in Ethereum
9. The concept of fog computing may be unfamiliar to many chain friends, but it is the most important aspect of ether fog to attract Xiaobian. In fact, the concept of fog computing has been known for a long time, and I always think that fog computing is the future development direction. When it comes to fog computing, we should start with cloud computing. In fact, the cloud computing we see now evolves from the cluster of independent servers, that is, from the original centralized independent servers to large server clusters, but in the final analysis, it is still a form of centralized computing
compared with the existing cloud computing, fog computing does not rely on the remote server located in the central computer room, but intelligently connects to the nearest distributed computer resources, so as to achieve the most efficient utilization of computing resources. This topology is characterized by decentralized peer-to-peer network, which is a perfect match with blockchain. If cloud computing represents efficient computing power in the Internet era, then in the era of Internet of things and value networking blockchain, fog computing should be the most efficient way of computing power networking
therefore, compared with the evolution of cloud computing, which is a kind of centralized computing, fog computing is to share computing tasks with all kinds of powerful devices around us, and realize the evolution of decentralized and distributed computing, which coincides with the philosophy of blockchain itself. However, it is necessary to encourage the owners of distributed computing resources to contribute computing power to the fog computing network. It is not only difficult for centralized enterprises (such as Cisco) to organize supply and demand market settlement in real time and monopolize, but also contrary to the decentralized distributed philosophy of fog computing itself, which is difficult to be widely recognized, It is difficult to find a satisfactory solution on how to settle the compensation of fog calculation reasonably
we can see that Amazon's AWS, Microsoft's azure and Alibaba's aliyun are all centralized operators operating centralized computing services, and the combination of blockchain value network and cloud computing network, which are both decentralized philosophy, is almost perfect. Ethereumfog is born for this purpose. Upgrading Ethereum based on Ethereum will really bring fog computing to us. In the near future, many personal computing devices may contribute their computing power to do useful things on ethereumfog chain, and do not waste every resource to earn corresponding returns< We use cloud computing, but it runs in the remote data center; Fog is close to the ground and lingers around us. Fog computing makes both computing and storage decentralized distributed on the devices around us. The combination of blockchain and value Internet makes more people willing to let their computing resources participate in it. The organic combination of supply and demand is becoming more powerful. Ethereumfog etherfog (ETF) is opening the door to the new world of Ethereum.
