Solidity is a contract-based high-level programming language. This platform's syntax is similar to that of the JavaScript programming language. The adoption of Solidity as a programming language has helped the Ethereum Virtual Machine. Solidity is a statically typed programming language that validates and enforces constraints during compilation rather than execution.

 This approach will be aided by typed programming languages that do testing at runtime rather than compile time. Furthermore, in object-oriented programming, this platform enables inheritance, allowing new objects to inherit the attributes of existing objects. A superclass, often known as a base class, is a kind of class that acts as the basis for inheritance. A subclass, also known as a derived class, is one that is a descendant of a superclass. Contracts for voting, contracts for crowd financing, blind auctions, multi-signature wallets, and other uses are all possible.

 The Ethereum Programming Language The Ethereum programming language's source code is written in Solidity 0.4.0, which has no impact on its functionality.

 The first line of code pragma solidity contract does not respond differently with a new compiler version. As a result, the word pragma is taken from the documentation, which says that pragmas are instructions for the compiler on how to handle source code. The preprocessor command pragma once tells the compiler to only compile the source code once.

 The line unit stored data declares the type unit's state variable stored data. The functions change the value of the variable and may be used to modify or retrieve it. Believe it or not, this is an Ethereum contract, although a very basic one. This contract's characteristics allow you or anybody else to retain a single number that everyone on the world may access, with no practical way to prevent you from revealing it. Anyone could just call set with a different value and change your phone number, but it would be recorded in the blockchain's history. The line unit stored data declares the type unit's state variable stored data.

Is it beneficial to devote time to Solidity?

The key issue now is whether the effort is worthwhile. If you want to work with Solidity, you must be willing to try new things. If one must first become an expert before obtaining blockchain-related skills that may be very useful, one must be familiar with programming languages. For example, this Bounty x job posting for any Solidity developer requires applicants to be proficient in AngularJS, NodeJS, and GoLang in addition to Solidity.

If you're willing to devote a few years of your life to learning Solidity, give it a go. You're probably going to have a stable employment for the foreseeable future. Finding, training, and employing Solidity Developers is a time-consuming and complicated process for a company. There is now a huge demand-supply imbalance in the market for an experienced Ethereum blockchain developer.

Smart contracts provide the following advantages: Autonomy —Because you are the one carrying out the activity, you do not need a broker, lawyer, or other intermediary to ensure compliance. While we're on the subject, the fact that execution is verified automatically by the network rather than by one or more possibly biased individuals removes the danger of third-party misuse.

Your documents are safely kept on a shared ledger. Someone cannot claim that they misplaced it.

To summarize, 

The Ethereum blockchain network is one of the world's largest and most frequently utilized blockchain networks. It is also one of the largest open-source projects in the world, with go-ethereum being among the most popular projects on Github. Since its first release in 2015, Ethereum has progressed toward its eventual aim of creating a decentralized global computer capable of replacing many of the centralized programs we rely on every day.

The Ethereum community and network, on the other hand, have a long way to go before they can accomplish this objective. This article will provide a short overview of Ethereum's accomplishments so far, followed by a discussion of the network's forthcoming and much anticipated release. This version is referred to as Ethereum 2.0 or Serenity (used interchangeably from now on). It will be the Ethereum community's most important and thorough upgrade to yet.

The update clearly demonstrates the growing need for an ethereum blockchain engineer. Having an ethereum certification will put you ahead of the competitors in all job fields.

What is Ethereum 2.0, exactly?

Eth2 is a collection of enhancements intended to improve Ethereum's scalability, security, and long-term viability.

As a result of this update, Ethereum will switch from PoW to PoS and will introduce sharding. The Ethereum network will save a substantial amount of energy, enable more transactions to be handled concurrently, and enhance network security.

What precisely is the improvement?

Proof-of-Stake has taken the role of Proof-of-Work.

The use of Proof-of-Stake as a consensus mechanism was one of the most significant developments brought about by the introduction of ETH2. With a growing number of users and a massive volume of transactions, Ethereum required a more efficient consensus mechanism, and Proof-of-Stake seemed to be the ideal choice. That's why Serenity's main aim was to go from PoW to PoS.

Miners are not required in PoS. In reality, there are no computer resources needed.

Proof-of-

Stake was a significant upgrade to the Ethereum network, and its authors feel it was unavoidable since it solves three fundamental issues with Ethereum 1.0.

PoS is more environmentally friendly since it does not need miners to answer difficult arithmetic problems with thousands-of-dollar rigs, which harms the environment. Participation in the network does not need the development of any new energy-intensive processes.

Increased security – With a PoS consensus mechanism, 51 percent of assaults are significantly more difficult to carry out since attackers would require a substantial amount of money to do so. It's technically still conceivable, but it's very improbable.

It's scalable because PoS enables sharding, which would be impossible to do if Ethereum utilized the PoW paradigm.

What happens to the older ETH?

If you hold Etherium right now, you may be concerned that it will lose value after 2.0 is released. The most essential point to remember is that when 2.0 is launched, the currency will remain same; only the Blockchain technology that supports crypto assets will change. As a result, your tokens will not become outdated, nor will you be compelled to purchase new tokens - no transfers will be needed.

Will the release of Ethereum 2.0 have an effect on DApps?

One unsolved issue with the Ethereum 2.0 upgrades is the potential effect on current DApps. Is it going to be like Apple, where newer iPhones stop supporting older apps?

It's conceivable that DApps won't work with the updated blockchain platform. Another risk is that once the network is in place, bumps in the road may interrupt business and cause operations to be delayed.

Bringing it all together
