In this course we are going to explain to you what the blockchain technology is and what its properties are that make it so unique.
Why Learn Blockchain?
Blockchain is a powerful technology with applications in fields such as cryptocurrency, healthcare, insurance, government, identification, supply chain, data management, and many more. By understanding the fundamental mechanisms that power blockchain, you can join the conversation and discover use cases for blockchain and Ubricoin itself as an use case for Universal health.
In this course, you’ll learn the structure and properties of the blockchain itself and the individual blocks that make it up. You’ll understand the blockchain features that provide security between different blockchain participants.
Notes on Prerequisites:
The majority of this course requires no prior knowledge just a cup of coffee.
We are going to learn how smart contract is implemented, deployed and executed within Ethereum environment.This second course of the Blockchain specialization will help you design, code, deploy and execute a smart contract – the computational element of the blockchain technology. Smart contracts allow for implementing user-defined operations of arbitrary complexity that are not possible through plain cryptocurrency protocols. They allow users to implement conditions, rules and policies of the domain applications. Smart contracts are a powerful feature that, when properly designed and coded, can result in autonomous, efficient and transparent systems. You will design and program smart contracts in Solidity language, test and deploy them in the Remix development environment, and invoke them from a simple web interface that Remix provides. This course features best practices for designing solutions with smart contracts using Solidity and Remix IDE.
Smart Contract Basics
-The purpose of this module is to introduce the reasons for a smart contract and its critical role in transforming blockchain technology from enabling decentralized systems. We will explore the structure and basic concepts of a smart contract through examples, and illustrate Remix (remix.ethereum.org) web IDE for deploying and interacting with a smart contract.
Putting it all Together
-This module focuses on the development of the Ballot smart contract incrementally to illustrate various features including time dependencies, validation outside the function code using access modifiers, asserts and require declarations, and event logging.
-This module will focus on best practices including evaluating whether a blockchain-based solution is suitable for your problem, designing Solidity smart contracts, and those relating to Remix IDE.
