Which Programming Language is Best for Blockchain?

November 2, 2021 Comments Off Roxana read

Considered at the base of the cryptocurrency revolution, blockchain has made a name for itself in modern society. It helps people carry out transactions anonymously with other people. Blockchain also aided in the rise of popularity with bitcoin and other digital currency methods.

With blockchain continuing to be a part of companies’ systems, the need for blockchain developers has risen as well. Thus, developers should be aware of which programming language is best used with blockchain.

Java

This is one of the powerhouse languages that has many features, adaptation capabilities, high-quality performance, and more. Java is best used for web development. It’s object-oriented, concurrent, class-based, and general-purpose too. Within the blockchain, Java is most helpful when creating web pages with high interactivity. It can also be used to develop simple, immutable blockchains. Developers in blockchain like this language because it has high portability and cross-platform capabilities. The combination of Java and blockchain has been incorporated into Ethereum, BitcoinJ, and IBM blockchain.

Python

Known for its low learning curve and simplicity, Python has numerous libraries as well. Its extensive, active community of developers ensures the language is constantly improving. This programming language can be used to write smart contracts for blockchain, which the latter’s developers find extremely beneficial. Python and blockchain have led to the creation of smart contracts written for Hyperledger and NEO. Ultimately, it’s the combination of Python’s libraries, easy to learn the system, and wide range of uses that makes it a great language for blockchain development.

C++

Unlike the other programming languages mentioned, C++ holds many principles that blockchain does. Some of these include:

Data hiding
Encapsulation
Polymorphism
Abstraction

In fact, C++ has helped form the basics that makeup blockchain. Bitcoin, the most widely-known use of blockchain was created using C++. Some of the language’s features like its object orientation and complex multi-threading capabilities are things blockchain developers love about the language. While Python is easier to learn, Java is harder to grasp and C++ is a bit more difficult to understand than Java. However, it’s very similar to the blockchain and has been behind the development of blockchain projects such as Ripple, Monero, QTUM, and Stellar.

Other Notable Programming Languages

JavaScript and Solidity are other programming languages blockchain developers could consider. While they are slightly less popular than most of the other languages mentioned, they have strengths of their own within the blockchain industry.

Summary

Developers all have their own methods and tools. Blockchain developers are the same way, though the foundation of every development project includes the choice of which programming language is used. The blockchain industry is becoming more popular, meaning the knowledge of things like Bitcoin is spreading as well. The benefits of blockchain development boil down to the implementation of languages such as Python, Java, C++, JavaScript, Solidity, or any other language that fits its overall purpose. A top choice would be C++ since it and blockchain are more closely connected. But, with its steeper learning curve, Python might be a simpler option. Java could be solid middle ground. In the end, analyzing each language in correspondence with the purpose of the development project will help developers decide which is the best one to use.

Business in 2021: Best Blockchain Trends

October 27, 2021 Comments Off Roxana read

Security is vital for any business. In 2021, and in the past decade, the need to preserve and protect data has significantly increased. With the world heavily relying on technology in recent years, it has also become harder to do that. Blockchain, or a secure way to securely contain and store data, is how businesses prevent anyone from stealing data or compromising their systems.

This has since made the use of blockchain more widespread. As much as one-third of the customer base worldwide utilizes blockchain to some capacity. And, just like with any tool, there are trends that can help companies implement those tools better.

There are 3 main trends of blockchain that businesses should pay attention to:

Blockchain as a Service (BAAS)
Innovation evolution
Tokenization

Blockchain as a Service (BAAS)

This contains the ability to test Distributer Ledger Technology or DLT. Corporations like Amazon that process millions of transactions a data benefit significantly from blockchain and its features, including BAAS. Other companies such as Microsoft, HP, IBM, and Oracle all use BAAS as well.

Innovation Evolution

As technology evolves, innovation increases. Blockchain is included in that, with many industries jumping on the blockchain train. Some examples are:

Supply chain management: Walmart
FinTech: Fidelity
Auto: Ford

More and more transactions are completed globally as technology becomes increasingly ingrained into society. It makes the need for blockchain a key component in data security.

Tokenization

Known as the substitution of money for digital currency (or tokens), tokenization has quickly risen in popularity in recent years. The most common example is Bitcoin. Although the knowledge of tokenization isn’t as wide, it’s still growing in use and implementation for businesses.

Top Industries Using Blockchain

Gaming

The gaming industry brings in millions of dollars every year, often even billions. Cryptocurrency and blockchain use has become an option for in-game purchases. Blockchain helps players and companies keep track of purchases, digital items, and even aids game developers in monetizing their work.

Food

This is a very sensitive and important industry that benefits from being able to keep track of, as well as trace, food products securely across different areas of the supply and demand process. Perishable items in particular need blockchain to ensure any weaknesses, incorrect information, or other errors can be easily referred back to in order to take care of any issues that may arise.

Conclusion

Blockchain’s ability to protect data while also offering other features, such as tokenization, leads it to take a comfortable role in current society. Heavily reliant on technology, the world is even more dependent on data security and privacy. The handling of information (i.e. debit and credit card numbers, addresses, bank account information, etc) has always been the main component of online shopping, among many other things. The security blockchain provides regarding transactions, which contain that information, ensures not only customer privacy for example, but also trust. Digital interactions are becoming increasingly vital in society and the protection of the information associated with them must be able to keep up.

What Is Solidity? What Are Its Use Cases?

October 25, 2021 Comments Off Roxana read

From developers at the Ethereum Blockchain Platform, Solidity was created. This is a contract-oriented programming language that’s also high-level. It’s typically used for writing smart contracts and incorporating them into Ethereum’s Virtual Machine. One of the Solidity’s features is the ability to add self-enforcing business logic into the smart contracts it can write. Additionally, Solidity is based on the JavaScript syntax.

Features of Solidity

State objects, data types, variables, and more are supported
One contract can hold many type-safe functions thanks to its Application Binary Interface
Contracts holding hierarchy maps and structs have many member variables
Has C3 linearization, which supports many inheritances

Developing with Solidity

Data types such as string literals, Booleans, integers, and modifiers are all supported when developing projects with Solidity. For integers, Solidity can process signed and unsigned domains, as well as runtime exceptions. Prior to executing code, modifiers analyze the consistency of the code’s conditions to ensure it runs smoothly. Solidity also allows for string literals that are represented using single or double-quotes. Lastly, Booleans apply a false and true label to the numbers 0 and 1 respectfully. This typically occurs when using logical operators.

All of these functions can be done with Solidity. More than that, Solidity can create ‘mappings’—the combination of arrays, operators, enums, and hash values organized into a data structure that presents values corresponding to locations. The JavaScript syntax Solidity is based on also allows it to support arrays of the multi- or single-dimensional variety.

Other Solidity Tools

EVM Disassembler (Evmdis)
Solidity REPL
Solgraph
EVM (Ethereum Virtual Machine) Lab

Examples of Incorporating Solidity

Auctioning

Specifically in blind auctions, Solidity helps keep anonymity between bidders. Without using Solidity, issues with fraud arise where bidders can see what their competitors bid. Solidity protects that information until the end of the auction.

Crowdfunding

Prior issues of crowdfunding when not incorporating Solidity include paying commissions to third parties and having someone else manage the data. Adding in Solidity decreases costs by eliminating that third party, among other things.

Voting

Fraud and data manipulation are big in voting circumstances. The most common example is the US presidential election. Implementing Solidity’s smart contracts, however, significantly cuts down on that—in most cases, removing it completely. It also streamlines the voting process while clearly outlining it at the same time.

Summary

The protection of data, even when it isn’t sensitive data, is extremely useful. It helps build trustworthy relationships as well, whether it’s between the situation and Solidity itself or two parties that Solidity mediates between, so to speak. When data needs to be concealed for the sake of keeping circumstances fair, as mentioned, Solidity does an excellent job of that. Of course, developers who know how to use this language can alter it to fit their development needs. Solidity also has the ability to protect important data for the entire duration of, say, a crowdfunding project or until the end of a voting or auction event, for example.

Ways To Develop, Test and Deploy Ethereum Smart Contract

October 24, 2021 Comments Off Roxana read

Ethereum was introduced in the blockchain space in 2015; ever since then, Vitalik Buterin, a Canadian-Russian programmer, brought new decentralized applications (dApps). Thus, Ethereum’s success is majorly attributed to implementing smart contracts.

Numerous people believe that smart contracts are a new conception and were invented with the Ethereum Blockchain site. But smart contracts came back in 1996 when the computer scientist Nick Szabo coined the term “smart contracts” and specified them as:

“Smart” because they are more functional than the inanimate paper-based ancestors. There was no use of artificial intelligence. A set of deals specified in digital form, including protocols within which the parties perform on the promises, is a smart contract.

His work inspired Vitalik, who developed Ethereum, and also other scientists and researchers.

Before we go deeper into creating and deploying the Ethereum smart contract, it is essential to understand the Ethereum site and how it works.

Ethereum, as a Blockchain site for developing decentralized operations.

Blockchain sites enable developers to create and also run smart contracts. Ethereum is one of the blockchain sites that can execute arbitrary code so that you can perform any program of your choice on Ethereum.

The Ethereum Blockchain is an implicit distributed infrastructure that facilitates you to complete projects using smart contracts.

Create your cryptocurrencies

With Ethereum, you can develop a tradable token that you can use as a new currency. Tokens created with the Ethereum site use a standard coin API to be compatible with any Ethereum blockchain wallet.

Develop virtual organizations

You can write a smart contract to make a blockchain-based platform. You can add more people to your forum and allow voting rules. Members of your platform can vote, and when it reaches the needed number of votes, the smart contract executes automatically.

.Build Apps

Ethereum enables developers to create secure and fault-tolerant decentralized apps that will eliminate intermediaries and also offer transparency.

Raise funds

Ethereum smart contracts are also used for fundraising. You can write a smart contract with a deadline with Ethereum. If you fail to accomplish the goal, all donations will be reimbursed to donors automatically with no disputes or commissions.

How Ethereum Blockchain site executes Smart Contracts?

You need to understand the Ethereum blockchain perfectly and how it runs smart contracts before developing a smart contract on the Ethereum site.

Firstly, let us understand the execution environment.

Ethereum Virtual Machine (EVM)

The goal of EVM is to offer a runtime environment for smart contracts developed on Ethereum. It is a significant supercomputer that executes all smart contracts.

As the name implies, Ethereum Virtual Machine isn’t a physical but a virtual machine. The functionality of EVM is restricted only to virtual machines; for illustration, it cannot make delayed calls on the internet or produce numbers randomly; it’s known as a simple state machine. Ethereum needs a programming language for the EVM because writing programs in an orderly language do not make sense.

Gas

Gas is a dimension unit used for assigning fees to each sale with a smart contract in the Ethereum virtual machine. Each computation in the EVM requires some amount of gas. The more advanced the calculation is, the more gas is needed to run the smart contracts.

Transaction fee = Total gas used*gas price

Solidity

It is an innovative contract programming language on Ethereum. It is developed at the top of the EVM; it is similar to the object-oriented programming language, which uses class and methods. It enables you to perform arbitrary calculations, but it is mainly used to send and receive tokens and store states. Solidity is majorly influenced by C++, Javascript, and Python so that developers can understand its syntax snappily when it comes to syntax.

It is best to understand Solidity programming language significantly to write an Ethereum Smart Contract effortlessly.

What is a Smart Contract?

Smart Contracts are business protocols or logic according to which all the deals on a Blockchain happen. The smart contract’s primary goal is to satisfy standard contractual terms like developing its token on ethereum. There’s a need to create smart contracts according to which all the computations on a ticket.

It is a script written in Solidity, compiled into JSON, and stationed to a specific address on the blockchain. a URL endpoint of a peaceful API to run some protocol; we can execute deployed smart contracts similar to a particular address by imputing the accurate data with Ethereum to assemble the compiled and deployed Solidity function through an HTTP Request.

Smart contracts are stationed to the decentralized database for a fee proportional to the containing code’s storage size. It is defined as a collection of code stored in the blockchain network, specifying the terms to which all parties are within the contract agreement.

We will be sharing the illustration of Ethereum smart contract creation with the use of Solidity programming language. So, it is first essential to understand what’s Solidity.

What is Solidity?

Solidity is a Javascript-like language developed majorly for developing smart contracts. It is typed statically and supports inheritance, complex user-defined types, and libraries,

Solidity compiler transforms code into EVM bytecode sent to the Ethereum network as a deployment transaction.

Here is a guide to creating and deploying Ethereum Smart Contracts with Solidity

Installing Prerequisites

Meta-mask Chrome Extension

MetaMask acts both as an Ethereum wallet and a browser. It enables you to interact with smart contracts and dApps on the website without the need to download the blockchain or install any software. All you need is to add MetaMask as a Chrome Extension, create a wallet and submit the Ether.

Although MetaMask is currently available for the Google Chrome browser, it is expected to launch for Firefox in coming years too.

You need to download the MetaMask Chrome extension before you can start writing smart contracts.

When downloaded and added as a Chrome extension, you can either create a new wallet or import an already existing wallet. It would help if you had some ethers in your Ethereum wallet to deploy Ethereum smart contract to the network.
