Remix Solidity IDE tutorial 1: Getters and setters
 
07:35
This is part 1 of the Remix tutorial. This tutorial explains how to use the online Remix Solidity IDE. In this video series different topics will be explained which will help you to understand how to use the Remix Solidity IDE. Solidity is an object-oriented programming language for writing smart contracts. It is used to implement smart contracts on various blockchain platforms such as Ethereum. It is one of four languages, the others being Serpent, LLL and Mutan (deprecated) designed to target the Ethereum Virtual Machine (EVM). Solidity is currently used as the primary language on Ethereum as well as on other private blockchains running on platforms that compete with Ethereum. Solidity is a statically-typed programming language designed for developing smart contracts that run on the EVM. Solidity is compiled to bytecode that is executable on the EVM. With Solidity, developers are able to write applications that implement self-enforcing business logic embodied in smart contracts, leaving a non-repudiable and authoritative record of transactions. It is recommended to watch each video sequentially as I may refer to certain Remix Solidity IDE topics explained earlier.

This tutorial explains how the two solidity compilers solc and the node library solc-js are related to each other. The node library solc-js is using soljson.js. soljson.js is created from the same solidity C++ code which created solc, but it is converted in JavaScript code using Emscripten Emscripten is a source-to-source compiler which can convert C/C++ code into JavaScript code. When you install the node library solc-js, it also installs the command line tool solcjs. A demonstration is given how to use solc and solcjs from command line.

Sorry for re-upload, there was a problem with the edit. In this video you will learn how to have two smart contracts interact with each other in Solidity. I will show you how one contract can call functions from another contract and how variables can be modified outside the contract itself. The code is available on my github: https://github.com/filipmartinsson/Solidity/tree/master/Contract%20Interaction

Instead of using GitHub gists, you now just post your address from one of your social media pages. (It will probably be easier for you than it was before) The reason they require you to do that is to prevent people from acquiring so much testnet ether that one could run attacks on the network... You're limited to like 20 ether every 3 days which is more than enough for testing. --- In this video we create a sample smart contract that will split any ether that is sent to it equally between 5 addresses. It can be used as a simple payroll contract. Each of the 5 addresses are our pretend employees that will call the 'withdraw' function to "collect their paycheck". Everything takes place on the test network. If you want to tip this video here is an ethereum address for this video: 0x631781ec9b44c7b5c4e9ea47fa122825f6c7a0c6

How to Write an Ethereum Election Smart Contract
 
07:41
How to Write an Ethereum Election Smart Contract https://blockgeeks.com In this video we are going to learn how to code up an election contract. We want to hold a free and fair election for a specified amount of time and only allow authorized people to vote in it We’ll start by defining a custom data type called a struct, which allows us to group together other data types, to define a Candidate struct. For a candidate in the election, we’ll keep track of their name and the number of votes they currently have. Let’s also define a struct for the Voter, that will store whether or not the voter has already voted, and who they voted for. We need to keep track of the owner of the contract as they will have special rights to authorize voters. We also keep a mapping to store voter information, as well as a dynamically-sized array of candidates that will be initialized on construction. The way to define an array is to simply use the square brackets after the data type of a variable. We’ll also keep track of the time when the election ends using an integer timestamp. We’ll initialize our list of candidates in the constructor. We pass in a name for our election, the duration of the election in minutes, and an array of candidate names. But wait, when we try to pass in a string array, we get a compiler error saying ‘nested arrays not yet implemented’. Why is that? This is because functions in Solidity cannot accept or return 2-dimensional arrays. but you might say hey we’re not actually using a 2-dimensional array here we’re just using a 1-dimensional array of strings. And even though it appears that way, under the hood, the string data type is implemented as an array of the bytes32 data type. So when we add the square brackets after string, its actually a 2d array of bytes32, which is not yet supported. As a workaround for now, we’ll just pass in 2 string arguments representing only two candidates in the election. If we wanted to support multiple candidates, we could just pass in an array of bytes32. We’ll define candidate objects using the provided names We also set our auctionEnd variable to be from now plus the specified duration in minutes. Now is a global variable, which is an alias to another global variable called block.timestamp. It returns a unix timestamp indicating the current block’s creation time, not the actual current time. Solidity also supports many time units such as minute, days, months. For now we’ll just use minutes. We’ll define an authorize function that allows the owner of the contract to give voting rights to any address. In this function, we initialize the Voter object for the address. Even though this looks like we are initializing an object in the voters mapping, that’s not actually what’s happening. Mappings can be thought of as hash tables which are virtually initialized such that every possible key exists and is mapped to a value whose byte-representation is all zeros, which is a type’s default value. So for bool it would be false, and for integer it would be 0. So when we initialize this Voter struct with false and 0, we’re not actually doing anything since these are already the default values set in the mapping. The implication being that anybody would be able to participate in the election, not just the authorized voters, and thats not quite what we want. To solve this, we’ll add a weight field to the Voter struct which will specify the weight of a vote. This will allow us to only count votes from people we authorize with a weight of 1. So to give voting rights, we don’t need to create a Voter struct and pass in all the fields, we just need to set the one field that won’t default to 0, in this case we set the weight for the voter to 1.
