Ethereum smart contract revenue
DTV share, Ethereum is an open source public blockchain platform with intelligent contract function. It provides decentralized virtual machines to handle point-to-point contracts through its private cryptocurrency, Ethernet. Key points: open source, smart contract function, public chain platform, Ethernet
Thank you for your recommendation. Here I would like to share with you the following:
forsage international crowdfunding, the revolutionary smart contract technology of the new generation platform, originated from the development of Russian technical team, provides distributed market participants with the ability to directly engage in personal and commercial transactions. The smart contract of forsage distributed global shared matrix project is open and can always be viewed on the Ethereum blockchain. These are real smart contracts, which will be implemented on the Ethereum public chain forever without any third party tampering. The global shared matrix project is completely decentralized, aiming to preach Ethereum, so that more players can know Ethereum, smart contracts and forsage code btshijie
what is Ethereum
Ethereum is often compared with bitcoin, but the situation is different. Bitcoin is a kind of cryptocurrency and distributed payment network, which allows bitcoin to be transferred between users
the Ethereum project has a bigger goal. As Ethereum said, "Ethereum is a distributed platform running smart contracts.". These smart contracts run on "Ethereum virtual machine", a distributed computing network composed of all devices running Ethernet nodes
"distributed platform" means that anyone can set up and run an Ethereum node just as anyone can run a bitcoin node. Anyone who wants to run "smart contracts" on nodes must pay the operators of these nodes in ether, which is a cryptocurrency related to Ethereum. Therefore, the person running the Ethernet node provides computing power and gets paid in the Ethernet, which is similar to the way that the person running the bitcoin node provides hash power and pays in bitcoin
in other words, although bitcoin is only a blockchain and payment network, Ethereum is a distributed computing network, and its blockchain can be used for many other things. Details are provided in the Ethereum white paper
what is smart contract
smart contracts are applications that run on Ethereum virtual machines. This is a distributed "world computer" with computing power provided by all Ethereum nodes. Any node providing computing power will pay in ether digital currency as a resource
they are named smart contracts because you can write "contracts" that execute automatically when you meet the requirements
for example, imagine building a KickStarter like crowdfunding service on Ethereum. Someone can set up an Ethereum smart contract to pool funds to others. The smart contract can be written as follows: when $100000 of currency is added to the pool, it will be sent to the recipient. Or, if the $100000 threshold is not reached within a month, all currencies will be returned to the original holder of the currency. Of course, this would use ether instead of dollars
all this will be done according to the smart contract code, which can automatically execute the transaction without the need for a trusted third party to hold the currency and sign the transaction. For example, KickStarter charges 5% above the 5% payment processing fee, which means it will charge $8000 to $10000 for a $100000 crowdfunding project. Smart contracts don't have to pay a fee to a third party like KickStarter
smart contracts can be used for many different things. Developers can create smart contracts to provide functions for other smart contracts, similar to the way software libraries work. Alternatively, smart contracts can simply be used as applications to store information on the Ethereum blockchain
in order to really execute the smart contract code, someone has to send enough Ethernet tokens as the transaction fee - how much depends on the required computing resources. This costs the Ethereum nodes to participate and provide computing power. The global shared matrix project, which is completely decentralized, aims to preach Ethereum and let more players know Ethereum, smart contracts and forsage code btshijie
The smart contract has been written for a long time
if they can add changes, the description is centralized
the contract is written into the Ethereum smart contract, which is a contradiction sentence
the financial customer service doesn't understand, which is very unreliable

what is Ethereum

related: what is bitcoin? How does it work
Ethereum has a bigger goal. As Ethereum says, "Ethereum is a distributed platform running smart contracts.". These smart contracts run on "Ethereum virtual machine", a distributed computing network composed of all devices running Ethernet nodes
"distributed platform" means that anyone can set up and run an Ethereum node just as anyone can run a bitcoin node.

in other words, although bitcoin is only a blockchain and payment network, Ethereum is a distributed computing network, and its blockchain can be used for many other things. Details are provided in the Ethereum white paper
what is ether
Ethernet is a digital token (or cryptocurrency) related to Ethereum blockchain. In other words, Ethereum is the token and Ethereum is the platform. But now people often use these terms alternately. For example, coinbase allows you to buy Ethereum, which stands for Ethereum
this is technically "altcoin", which actually means a non bitcoin cryptocurrency. Like bitcoin, ether is supported by distributed blockchain - in this case, Ethereum blockchain
developers who want to create applications or Ethereum smart contracts on Ethereum blockchain need Ethernet token to pay for nodes to host it, while users of Ethereum based applications may need Ethernet to pay for services in these applications. People can also sell services outside the Ethereum network and accept Ethernet payments, or they can sell Ethernet tokens in cash - just like bitcoin
Generally speaking, the steps of deploying smart contract are as follows:
- start an Ethereum node (such as geth or testrpc)
- use Solc to compile smart contracts=& gt; Get the binary code
- deploy the compiled contract to the network This step will consume Ethernet currency, and you need to use the default address or specified address of your node to sign the contract.)=& gt; Get the blockchain address and ABI of the contract (JSON representation of the contract interface, including variables, events and callable methods) The author confused ABI with contract interface here. ABI is the binary representation of the contract interface.)
- use the JavaScript API provided by web3.js to call the contract Depending on the type of call, it may consume Ethernet currency.)
Eth is a kind of digital token of Ethereum, which is regarded as "bitcoin version 2.0", and uses the blockchain technology "Ethereum" which is different from bitcoin
it is an open-source public blockchain platform with smart contract achievements 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
Technical Architecture:
the smart contract endows the account book with programmable characteristics. Blockchain 2.0 realizes the function of smart contract by running code in the way of virtual machine, such as Ethereum virtual machine (EVM) of Ethereum. At the same time, this layer forms a decentralized application (DAPP) by adding a foreground interface that can interact with users on the smart contract
of course, in some technical documents, it is reasonable to think that DAPP should be a separate application layer above the smart contract layer, as long as it does not affect the understanding
