Blockchain Tutorial- Know Basics of blockchain

In this Blockchain tutorial, we will understand the definition of blockchain, blockchain wallet and some basics of blockchain.

what is Blockchain?

The blockchain ledger helps to produce transparency for transactions. though several bitcoin transactions are in some ways anonymous, the blockchain ledger can link people and firms to bitcoin purchases and possession by permitting individual parties, referred to as miners, to make payments and verify transactions. instead of a central company presiding over the utilization of bitcoin, these blockchain originators serve central roles within the management and administration of this different currency system.

what is Blockchain wallet?

A blockchain wallet is a digital wallet that permits users to manage bitcoin and ether. Blockchain wallet is provided by Blockchain, which is a software company founded by Peter Smith and Nicolas Cary.

Creating an e-wallet with Blockchain Wallet is free, and therefore the account setup method is done online. people should provide an email address and password that will be used to manage the account, and therefore the system can send an automated email requesting that the account be verified.

Once the wallet is created, the user is given a wallet ID, which is a unique identifier similar to a bank account number. wallet holders will access their e-wallet by logging into the Blockchain web site, or by downloading and accessing a mobile application.

The Blockchain wallet interface shows the current wallet balance for both bitcoin and ether tokens and displays the user’s most recent transactions. Users can send a request to a different party for a particular amount of bitcoin or ether, and therefore the system generates a unique address that will be sent to a 3rd party or converted into a QR code. The send/receive process is similar to sending or receiving funds through Paytm or Paypal but uses cryptocurrency instead.

Blockchain Basics

A blockchain could be a digital info for storing info. info is kept in groups referred to as ‘blocks’. A blockchain is a bit like an excel spreadsheet. However, blockchains have some very special options that build them totally different.

Blockchains are:


A blockchain isn’t kept in one place — it has no center. it's stored across many different computers. These computers are known as nodes. Blockchains are called peer-to-peer networks because there are not any third parties like Microsoft, Google, or Facebook involved. So, not one single entity has control over the data on a blockchain, users and each blockchain developer each other one another directly rather than through a 3rd party.


All the data on a blockchain is public. this implies that everybody will see it.

Guided by consensus

This means that before new information is added to the blockchain, more than 1/2 the nodes have to agree that it's valid before it's added. It protects the blockchain from fraud.


Immutable this means that once information is added it can’t be modified or removed. info on a blockchain is protected by this implies that it's encrypted and nearly not possible to hack.

Ethereum has its language known as Solidity. this implies that even experienced developers must learn a brand new language to be a blockchain developer and begin building dApps. However, Solidity is similar to alternative languages like C++ and Javascript. Most users can find Solidity tough, to start with. However, users who know Javascript or C++ can realize it easier.


NEO is concentrated on providing platforms for digital businesses in the long run. It follows Chinese business rules and works closely with the Chinese government. it is also presently a quicker network than Ethereum. this is nice for applications that may ought to method a lot of transactions per second!

Ethereum conjointly has links with big businesses like Mastercard and Samsung. However, Ethereum is more focused on encouraging users to develop the blockchain than neo is. It also has the largest dApp building community of any other blockchain. this is why I think Ethereum is the best platform for a newcomer to begin their development training.

There are 3 versions of blockchain.
1-Blockchain 1.0: Currency
2-Blockchain 2.0: Smart Contracts
3-Blockchain 3.0: DApps
