Solidity Contract Lesson

Solidity Contract Lesson - 坚固性合同课程

This a lesson on writing a smart contract in Solidity. In order to understand smart contracts, you first need to know what the Ethereum blockchain is and how it works. It does not have a centralized source like a cloud platform such as Google Cloud or Amazon Web Services would. Developers run Ethereum on their machines and are paid in cryptocurrencies called ether. A cryptocurrency is essentially a digital asset. The ledger that tracks these assets is the Ethereum blockchain (there are other types of blockchain that also serve as ledgers for cryptocurrencies). The Ethereum blockchain is the database that tracks what is owed, stored, and runs smart contracts.

Developers who run the Ethereum blockchain on their machine for ether are called miners. Gas is the cost necessary to perform transactions on the network based on the amount of memory your contract uses. Miners who use their computer to run the Ethereum Blockchain (virual machine) set these costs based on supply and demand. The network that all these computers are running on to mine is the Ethereum virtual machine. That is the network that the Ethereum Blockchain runs on. It is in your best interest to ensure that your program uses the least amount of memory and data to save money, or gas.

A contract that runs on the Ethereum blockchain automatically executes when all the conditions are met. Since, digital assets can be transfer and contracts can be written this is valueable because it eliminates the need for a lawyer to write a contract and a bank to transfer money.

This Lesson is on Writing Contracts in Solidity

In the Solution Folder there is a written smart contract and a step by step guid to writing it and it is doing.

If you want to try it on your own first there is a starter code file and instructions in the starter code on what to do.

In the lesson folder there is a guide to writing in solidity which talks about syntax, the Ethereum blockchain is better explained there as well, and the solution at the end of the lesson is explained.

Key take aways from this Lesson:

  1. Why blockchain developers are so valuable
  2. Ethereum blockchain fundamentals How the Network works Mining and what it is Gas Ether
  3. Smart Contracts and how they work!
  4. Solidity fundamentals including: Declare the version of Solidity for the compiler to use with pragma. Create a contract. Events (declare and emit) Functions Variables Returns If/else statements For loops Mapping
  5. The remix IDE How to write/compile a contract on remix

The next lesson will be about:

In our next lesson we will learn how to deploy contracts and create and use real addresses for contracts on the Ethereum network.

Solidity Contract Lesson - 坚固性合同课程

这是一堂关于在Solidity中编写智能合约的课。为了理解智能合约,您首先需要知道以太坊eth区块链blockchain是什么以及它是如何工作的。它没有像googlecloud或amazonwebservices这样的云平台那样的集中资源。开发者在他们的机器上运行以太坊eth,并以称为以太的加密货币支付。加密货币本质上是一种数字资产。跟踪这些资产的分类账是以太坊eth区块链blockchain(还有其他类型的区块链blockchain也可以作为加密货币的分类账)。以太坊eth区块链blockchain是跟踪所欠、存储和运行智能合约的数据库。

在以太机器上运行以太坊eth区块链blockchain的开发者称为矿工。Gas是根据合同使用的内存量在网络上执行事务所需的成本。使用计算机运行以太坊eth区块链blockchain(虚拟机)的矿工根据供需情况设定这些成本。所有这些计算机运行在我的网络上的就是以太坊eth虚拟机。这就是以太坊eth区块链blockchain运行的网络。确保您的程序使用最少的内存和数据来节省资金或汽油,这对您最有利。

以太坊eth区块链blockchain上运行的合约在满足所有条件时自动执行。因为数字资产可以转让,合同可以写,这是有价值的,因为它消除了律师写合同和银行转帐的需要。

Solidity Contract Lesson - 坚固性合同课程

这节课是关于用坚固性写合同的课程

在解决方案文件夹中,有一个已写入的智能合约和一个用于写入它的分步guid,它正在执行。

如果您想先自己尝试,那么在启动程序代码中有一个启动程序代码文件和操作说明。

在课程文件夹中,有一个关于语法的完整性写作指南,以太坊eth区块链blockchain也在这里得到了更好的解释,并且在课程结束时解释了解决方案。

这节课的主要收获:

  1. 为什么区块链blockchain开发者如此有价值
  2. 以太坊eth区块链blockchain基础网络如何工作采矿以及什么是气体乙醚
  3. 智能合约及其工作原理!
  4. Solidity基础知识包括:声明Solidity的版本,以便编译器与pragma一起使用。创建合同。Events(declare和emit)函数变量返回循环映射的If/else语句
  5. The remix IDE How to write/compile a contract on remix

下节课将讲述:

在下一课中,我们将学习如何在以太坊eth网络上部署合约,以及如何为合约创建和使用真实地址。
