Download GitHub from Ethereum

1. 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)

2. What does it mean that there is no verification of the display in the browser and the release contract code? He certainly didn't have time to do it.

you can search our official account at station B to view it. If you can't find the required content, you can get it by private chat

thank you for your support

4. Eth is a kind of digital token of Ethereum. Developers need to pay eth to support the application. Ether currency, like other digital currencies, can be bought and sold on the trading platform
generally speaking, Ethereum is an open source platform, digital currency and blockchain platform, which provides developers with a platform to build on the blockchain

5. Ethereum source code

6. 1. Preparation. Windows 64 bit system, C disk to reserve a certain space, download and install vs2015 (the official note only supports vs2015, to be verified), cmake I use 3.10.1, the system language to non Unicode language, such as English (U.S.), otherwise there will be errors in the final compilation
2. Project clone to local, project address:
3. Execute submole updata -- init
4. Install script in the directory_ Deps.bat is copied to the root directory and executed. This step will download hunter, boost, libjson, etc. to Disk C, which takes a long time. Please wait patiently
5. Go to the directory of the project and create the build subdirectory,

7. Constantinople, the next system wide upgrade of Ethereum, is coming to a node near you

Constantinople includes five different Ethereum improvement proposals (EIPs), which were completed on August 31. Once released on Ethereum, these proposals will permanently change the blockchain through a series of new backward compatible upgrades

this means that the nodes of the computer network running the Ethereum software must be updated with the whole system, or continue to run as separate blockchain entities

the system wide upgrade has caused quite a lot of dramatic events in the past, which should be more formally referred to as "hard fork". Most notably, when some users disagree with this change, it may lead to two different versions of the same blockchain running at the same time. At present, if you want to invest in Ethereum, you can trade in the bitnet exchange.

Solidness language is a special language for writing and executing smart contracts. It is a contract oriented high-level language running on the basis of Ethereum virtual machine. It was first proposed by the former CTO and co-founder Gavin wood of Ethereum in August 2014. Later, Ethereum developers set up a special team to continuously improve solidness language, At present, it is still under development and optimization. The development storage area on GitHub is HTPs / github.com/thereum/solidness. Here we can learn the most comprehensive details and related documents about the development and iteration process of solidness language. In terms of language style, solid language is deeply influenced by C + +, Python and JavaScript. It is a static programming language, compiled in bytecode mode, so it can run on Ethereum virtual machine. Gavin wood uses the syntax rules of ECMAScript scripting language of JavaScript for reference when developing solid language, which makes it somewhat similar to the existing web development language, but it is quite different. For example, solid language has static type, variable return function and so on. The most important point is that solid language can write contracts with self executing business logic and embedded in smart contracts. Therefore, it is not only one of the basic programming languages of Ethereum, but also the basic programming languages of most other Ethereum based blockchain procts (blockchain 2.0) with smart contracts, It is widely used in the vast majority of blockchain procts, such as hyperledger project, which is developed with soliditv language

the Xueshuo innovation blockchain Technology Workstation of Lianqiao ecation online is the only approved "blockchain Technology Specialty" pilot workstation of "smart learning workshop 2020 Xueshuo innovation workstation" launched by the school planning, construction and development center of the Ministry of ecation of China. Based on providing diversified growth paths for students, the professional station promotes the reform of the training mode of the combination of professional degree research, proction, learning and research, and constructs the applied and compound talent training system

9. PCIe refers to the slot on the motherboard, which can also be called the PCIe channel. Nvme protocol is m.2 SSD, so the two are not the same. PCIe is not a protocol. If your motherboard has two m.2 SSD interfaces, the first SSD you install is the system, and the second interface can also use the m.2 SSD, just occupying the PCIe channel,
