 is the next of the internet which solves the existing problem of lack of data ownership by users .

It is transparent, distributed and immutable , So no one can tamper the data once its written into the chain. 

Before Diving deep , lets quickly compare between web1.0, web2.0 , web 3.0 :

 All the webapplications built on the top of internet are static , which means users cannot write the content but only read the content.

In web 2.0 users can read the content , also write the content , which means web-applications being built on top of internet has the capability to be dynamic . This gave a massive boom for the Social Media, but the problem is users cannot have control of thier own data and the webApplications are dependent on servers.

It is the next era of the internet where users can read, write and also own their content. This is powered by distributed ledger technology . All the applications ( 

 ) being built on top of this distributed system will have a ~100% uptime.

What is web 3.0 ?

What is Powerledger

Before getting introduced to Solidity lets quickly jump into what is web 3.0 first !

“Web 3.0” the next internet era which is being fastly adopted by the users for the reason as it’s backed by blockchain.

Blockchain is means of storing data so that it is 

OKay ! Fine …. But what is the necessity of using Blockchain

Let’s take the recent issue of Cloudflare! As Cloudflare is down ,in a snap entire internet was down..This reflects the companies being dependent on servers..If the servers are down, boom!!! all services aredown.A quick solution for this case is usage of blockchain.If their data is distributed i.e among the nodes, Even if few nodes go down , few other remain and the services keep running at the regular pace.

Secondly blockchain enhances the security and decentralization which is very much essential in today’s world.

Now coming to the Solidity , its a programming language used for creating Smart contract on Ethereum blockchain.

Smart Contracts are the pieces of code that simply work on condition — action mechanism..This means for a set of the conditions the smart contract is deployed, the actions to be incurred are defined in the piece of code that helps in fast , accurate actions for solving real time problems

Solidity is a statically-typed programming language which means we have to define the type of variable before declaring a variable.

Sample Piece of Smart Contract Written in REMIX IDE

Now you can start writing smart contract even in your local IDE like Visual Studio Code. But at beginning it is useful to use REMIX IDE..

 ” , this word can be useful for making the compiler understand that the statements written under it belong to the particular contract..

Solidity is the well known programming language for writing contracts on EVM Chains

Intro to Solidity Programming

ERC-4337 is an Ethereum standard that achieves account abstraction on the protocol without any consensus-layer changes. Deployed on the Ethereum mainnet in March 2023, ERC-4337 makes it possible to transact and create contracts in a single contract account. It opens the door to user-friendly crypto wallet designs that could potentially facilitate broader adoption.
