Online Educational Course “Smart Contracts“

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.

Syllabus:

WEEK 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.

WEEK 2. Solidity

Our goal is to master the basics of Solidity, a high-level language that is a combination of Javascript, Java and C++. It is specially designed to write smart contracts and to target the Ethereum Virtual Machine. Learners will be able to follow demonstrations and practice using Solidity.

WEEK 3. 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.

WEEK 4. Best Practices

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.

Crypto 2020 Summit

Crypto 2020 Summit

29-31.01.2020

crypto2020summit.com

Crypto sectors covered:

1. Initial Exchange Offerings (IEO)

It’s no secret that the most money is now made on alt-coins over Bitcoin. But making money with alt-coins in 2020 is going to be far different than 2017. For one, initial coin offerings (ICOs) don’t exist. Instead, they’ve been replaced by initial exchange offerings (IEO).

The rules are different. But if you have the know how, the opportunity is the same (if not better). By the end of Crypto Summit you’ll know everything there is to know about IEOs. And you’ll know the best ones coming up just in time for the 2020 bull run.

2. Tokenized Security Assets

Security Tokens are opening up a massive market for investors all around the world, cutting out the middleman for the first time in history. Security Tokens are like ICOs backed by physical assets. They’re incredible opportunities to make money, but they’re highly regulated. Learn how you can get a piece of the profits without being an accredited investor (net worth over $1,000,000).

3. Lending and Interest on the Blockchain

With new blockchain protocols, it’s possible to earn interest from your crypto for the first time. For the first time, you can lend and invest your money anywhere in the world. Imagine investing in start-ups in hot developing countries. Improving their quality of life while earning huge returns. And it’s all on the Blockchain. No governments… no middlemen.
