There has been a great deal of interest in blockchain technology since the colossal upsurge in Bitcoin prices in late 2017, and as a result, many companies and individuals have reified in research and development of blockchain applications. A recent blockchain study carried out by Cisco revealed that, although blockchain technology will take time to be globally adopted, there is a mindset shift in blockchain applications.
What Is Blockchain?
Blockchain is a distributed digital ledger technology where transactions are recorded and stored chronologically. It is a public, decentralized, tamperproof platform that eliminates the need for intermediaries. These records, referred to as blocks, are linked using cryptography. The blockchain system, which is an open platform, allows transactions in an efficient, permanent, and verifiable manner. Parties carrying out transactions operate in anonymity.
Blockchain usage has brought relief in, otherwise traditional, platforms, having been successfully utilized in various sectors, including the health sector, infrastructure, financial services, asset management, cross-border payments, and government services such as passports. It’s easy to say that technology, as we know it, is undergoing strides of massive change. This has brought a massive shift from centralized systems to decentralized systems and applications.
At the forefront of technological changes is the growth of blockchain and key features, such as dApps or decentralized applications, these applications are built using blockchain and smart contracts, offering transparency, enhanced security, easier payments, and reduced censorship, since they operate without a central point.
Although there are over 1000 dApps in existence, decentralized technologies may be overly technical and confusing to ordinary people who don`t understand cryptocurrencies. However, this is changing due to the promotion of blockchain applications through systems like MetaMask and browsers like Chrome, making technology more accessible to mainstream audiences.
Blockchain enthusiasts envision that such technology would work best in a publicly accessible, open-source platform that is powered by users on a global network. Fortunately, the technology has opened up immense opportunities for both skilled technical experts as well as those with limited technical knowledge.
The steps on how to create a decentralized Blockchain application without any frameworks include:
1. Install Dependencies
2. Run Ganache CLI
Clone the repository source
Run Ganache CLI (Ganache refers to a simulator in the blockchain that runs locally in memory)
3. Open and Run the Node.js Console
Open up the Node.js console node.
Run the Node.js console. Node.js console refers to a built-in global method that is used to print messages at different levels to stderr and stdout. They are used to print the warning, informational, and error messages.
4. Compile and Interact With the Contract
Compile the contract within the Node.js console, described in Step 3 above, while ensuring that it has been initialized to communicate with the blockchain.
Interact with the contract through the Node.js console, and then in the browser, open index.html.
Watch Out for the Pitfalls
It is imperative to take note of the challenges experienced while coding. For instance, coding involves deciphering technical terms that are mind-boggling. These technical terms may inhibit interested individuals to become fully immersed in acquiring additional knowledge.
Coding also involves technical statistical analysis of data and structures, presenting challenges resulting from usage of technical acronyms and algorithms. Technology, especially blockchain technology, is evolving so fast that while an individual acquires knowledge in a certain area, it quickly and rapidly changes, so devs and enthusiasts will need to ensure they are up to speed in the latest advancements and relevant practical uses.
