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
ICO (abbreviated as initial coin offering) is the concept of initial public offering (IPO) derived from the stock market. It is the behavior of blockchain project to issue token for the first time and raise bitcoin, Ethereum and other general digital currencies
brief introction to ICO:
ICO is a blockchain instry term, which is a common way to raise funds for cryptocurrency / blockchain projects. Early participants can get the cryptocurrency generated initially as a return
because the token has market value, it can be converted into legal currency to support the development cost of the project. The tokens issued by ICO can be based on different blockchains. The common issue is based on Eth and BTS blockchain, which provides bookkeeping service and value consensus to realize global issue and circulation
ICO participants are very important for the success of a project. They will publicize the blockchain project in the community, so that the tokens generated by it can obtain liquidity before the transaction starts. However, the most important value of ICO participants is still the potential benefits brought by the project development or the price appreciation after the token issue

at 3:00 p.m. on September 4, 2017, the people's Bank of China led seven ministries and commissions, including the Information Office of the people's Bank of China, the Ministry of instry and information technology, the State Administration for Instry and commerce, the China Banking Regulatory Commission, the China Securities Regulatory Commission and the China Insurance Regulatory Commission, to issue the announcement on preventing the financing risk of token issuance (hereinafter referred to as the announcement)
the announcement points out that token issuance financing is essentially an unauthorized illegal public financing behavior, which requires that all kinds of token issuance financing activities should be stopped immediately from the date of the announcement, and at the same time, organizations and indivials who have completed token issuance financing should make arrangements such as refund
