What is a Software Library?

A software library is a collection of code and data used to develop and execute programs. This is one of the important things for creating and running a blockchain.

Blockchain is a technology that allows digital transactions to be carried out in a decentralized, transparent and secure manner. Blockchain uses cryptography, which is the study of how to secure information, to verify and encrypt data stored in interconnected blocks.

However, to create and run a blockchain, a software library is needed. It is a collection of code and data used to develop and execute programs.

So, in this article, we will discuss more about software libraries. Starting from its meaning, how it works, and why it is important for blockchain.

Understanding Software Libraries

A software library is a collection of code and data used to develop and execute programs. Software libraries usually consist of pre-written code, classes, procedures, scripts, configuration data, and so on.

This technology aims to help programmers and programming language compilers in building and running programs. Software libraries can also save time and resources, because programmers don't need to write code from scratch for every required function.

Software libraries can be divided into two types, namely static libraries and dynamic libraries. A static library is a software library that is included in a program during compilation, so that it becomes part of the program's executable file.

Static libraries have the advantage of fast performance and do not depend on external libraries. However, static libraries also have the disadvantage of large file sizes and are difficult to update.

Dynamic libraries are software libraries that are not included in the program during compilation, but are called when the program is run. Dynamic libraries have the advantage of small file sizes and easy to update.

However, dynamic libraries also have weaknesses in the form of slow performance and dependence on external libraries.

How Library Software Works

A software library can be illustrated by analogy as a library. For example, a library that stores various books containing information and knowledge.

Then, there was a writer who wanted to write a novel. To create the novel, the author can borrow books from the library that are relevant to the theme of the novel.

That way, writers don't need to look for information and knowledge from scratch, but can use existing books as references.

In this case, libraries are software libraries, books are code and data, and authors are programmers. Programmers who want to create and run programs can use software libraries that are relevant to the program's objectives.

In this way, programmers do not need to write code and data from scratch, but can use existing software libraries as references.

The Importance of Software Libraries for Blockchain

Software libraries are very important for blockchain. Because, blockchain is a complex technology and requires a lot of code and data to function.

Software libraries can help programmers create and run blockchain more easily and efficiently. Software libraries can also help programming language compilers optimize and secure the code used for blockchain.

Some examples of software libraries used for blockchain are:

Crypto++

Crypto++ provides various cryptographic functions, such as encryption, decryption, hashing, and digital signatures. This software library is used by several blockchain projects, such as Bitcoin, Ethereum, and Monero.

Web3.js 

Web3.js provides an interface to interact with Ethereum nodes via the JSON-RPC protocol. This software library is used by many applications that run on the Ethereum network, such as MetaMask, Uniswap, and MakerDAO.

Bitcoin Core

Bitcoin core provides a reference implementation for the Bitcoin protocol. Bitcoin Core is used by many nodes and wallets that participate in the Bitcoin network.

That's the article about this software library. Hopefully this article is useful and adds to your knowledge about blockchain technology, OK?
