Blockchain Tutorial: Table of Contents

Lesson 1: What Is Blockchain Technology? 

Blockchain technology is a new way of handling digital transactions that have started to gain traction in recent years. It works by creating an unalterable record of all the transactions that have ever taken place on a network called a blockchain. This means that no one can tamper with or edit the records without being detected and punished.

Lesson 2: Features Of Blockchain

Blockchain is a new technology that is changing the way we do business. Originally designed as a way to remove the need for a middleman in transactions, it has since been used for a variety of purposes, including but not limited to identity management, supply chain management, and data storage.

Lesson 3: Why Blockchain Is Important?

Blockchain is a distributed digital ledger of all cryptocurrency transactions. This technology has the potential to change the way we do business and could even have far-reaching implications for society as a whole. Here are four reasons why blockchain is so important:

• Blockchain is secure
• Blockchain is transparent
• Blockchain is tamper-proof
• Blockchain enables peer-to-peer transactions without reliance on a central authority or third parties like banks

Lesson 4: What Is Cryptocurrency?

Cryptocurrency is a digital or virtual currency that uses cryptography to encrypt its transactions and regulate the creation of new units. They are often traded on decentralized exchanges and can also be used to purchase goods and services. 

Lesson 5: What Is A Blockchain Wallet?

A blockchain wallet is a digital wallet that allows you to store, send, and receive cryptocurrencies like bitcoin and Ethereum. Blockchain wallets are similar to traditional bank accounts in that they allow users to easily transfer funds between their various accounts. But where banks rely on centralized systems to hold customers’ money, blockchain wallets use decentralized technology to manage transactions.

Lesson 6: What Is Ethereum? 

Ethereum is a decentralized platform that runs smart contracts: applications that run exactly as programmed without any possibility of fraud or third-party interference. It’s this unique feature that makes Ethereum especially appealing to developers and entrepreneurs, who can use it to build apps on top of it with no risk of censorship or theft.

Lesson 7: Bitcoin vs Ethereum: Which One is Better?

• Bitcoin is a decentralized digital currency that can be sent from user to user on the peer-to-peer bitcoin network without the need for intermediaries. Transactions are verified by network nodes through cryptography and recorded in a public dispersed ledger called a blockchain. 
• Ethereum is also a decentralized digital currency, but it goes beyond being just a payment system. It is also a platform that allows developers to build and run decentralized applications (dapps). These dapps can be used to create anything from smart contracts to Decentralized Autonomous Organizations (DAOs). 

Lesson 8: What Is Ethereum Mining?

Ethereum Mining is the process of using your computer to help power the Ethereum network and reward participants for their contributions. Every time a user sends a transaction on the Ethereum network, they are rewarded with Ether (ETH). This helps keep the network running and protected from malicious attacks.

Lesson 9: What Is A Smart Contract in Blockchain?

A Smart Contract is a contract that is executed through the use of blockchain technology. This involves a digital ledger of all contracts and transactions, which are tamper-proof and accessible by everyone on the network. Whenever someone tries to modify or delete a contract, their attempt will be recorded in the public ledger as well. This makes it difficult for anyone to falsify records or try to cheat other participants.

Lesson 10: What Is Dogecoin?

Dogecoin is a cryptocurrency that was created as a fun way to make online transactions more accessible. It started as an imitation of Bitcoin, but it has since developed its unique properties and currency system. Dogecoin uses a peer-to-peer network to facilitate transactions. Unlike many other cryptocurrencies, Dogecoin has a very easy-to-use blockchain, making it a popular choice for new cryptocurrency users. 

Lesson 11: Dogecoin vs. Bitcoin

Dogecoin and Bitcoin are both types of digital currencies. But what’s the difference between them?

• Bitcoin is more popular than Dogecoin
• Bitcoin offers greater potential for growth than Dogecoin does currently. 
• Dogecoin has an active community of supporters who give it extra liquidity and push its prices up during volatile markets. 
• Bitcoin is more centralized than Dogecoin – mining pools control about 50% of all hashing power on the network, while Dogecoin relies on users distributed across the web to contribute their computing resources. This creates more stability for Doges overall because individuals cannot corrupt or cheat the system easily as they can with Bitcoin.

Lesson 12: What is Dogecoin Mining?

Dogecoin mining is the process of using a computer to validate and add new transactions to the Dogecoin blockchain. Mining Dogecoin can be a fun way to earn some extra money, and it also helps support the development of the cryptocurrency. Miners are rewarded with Dogecoins for their participation in this process.

Lesson 28: Types of Blockchain

There are a few different types of blockchain, 

• Distributed ledger technology (DLT), also known as the blockchain, is a distributed database that maintains a continuously growing list of digital transactions. Transactions are spread across many nodes in the network, making it difficult for anyone to tamper with them. This makes it an excellent choice for cases where you need to track records that require transparency and trustworthiness, such as voting or contracts.
• A ConsenSys chain is similar to DLT in that every node keeps a copy of the data. However, unlike DLT, ConsenSys chains do not allow participants to add new entries without consensus from all other nodes in the network. This makes it useful for applications that require high security but low scalability (for example: tracking property rights). 
• Smart contracts are code segments that run on Ethereum Virtual Machines and can be used to execute contractual obligations between parties automatically. 

Lesson 29: What Is DeFi?

DeFi (distributed finance) is a term that refers to the use of blockchain technology and cryptocurrencies to facilitate financial transactions. DeFi platforms allow users to make direct payments or borrow money using cryptocurrency as collateral. These platforms also provide access to a wide range of financial products, including loans, credit cards, and asset-backed securities.

Lesson 30: What Is Ripple?

Ripple is a cryptocurrency that can also be used to transfer money between different currencies. Ripple works by creating a global network of financial institutions that uses the Ripple ledger to make international payments easier and faster. This network allows banks and other organizations to send money directly to each other without having to go through traditional banking systems.

Lesson 31: What Is Binance? 

Binance is a popular cryptocurrency exchange that offers users an easy and user-friendly platform to buy and sell cryptocurrencies. It has rapidly become one of the most popular exchanges in the world, with nearly two million registered users and over $1 billion in traded volume every day.
