Informações sobre o curso: 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. Main concepts are delivered through videos, demos and hands-on exercises.
Para quem é direcionado este curso: This course is for anyone interested in designing and developing smart contracts. Along with other courses of the Blockchain specialization, it provides the foundation to design and develop decentralized applications (the focus of the third course) on the blockchain. Mastery of content from the first course (Blockchain Basics) of this specialization is a prerequisite.

SEMANA 1
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.

Excellent Course
Great introduction to Solidity and designing contracts.
The instructor is very detail oriented and perfectly balances speed with detail. However the last assignment i.e project on creation of auction is not very helpful. There is no way to get details on why the code is failing. For eg, in my case I was able to compile the code on my compiler but it wasnt happening on the coursera interface. and there was no way to find out what the error was.

An amazingly simple yet pretty much as exhaustive an introduction as possible. Loved it!
