 With the rising use of blockchain technology for mining and storing digital currency and assets, blockchain has shot up in popularity in recent years. With multiple firms and organizations, now using this technology, blockchain developers are highly in demand. There is an increasing rise in the requirement of blockchain certifications and the demand for a good extensive blockchain course.

Fundamentally, blockchain can be described as a ledger technology that holds transactional records and ensures security, transparency, and decentralization. Blockchain technology cannot be controlled by a single authority. It’s a form of distributed ledger technology that holds the records of digital assets.

Blockchain technology assists in reducing risk in transactions and minimizing fraud with multiple ‘proof of stake’ blockchain networks which guarantee the valuation of assets and ensure the legitimacy of the transactions that occur. It brings transparency to transactions and decentralized digital assets.

Blockchain technology is based on the workings of peer-to-peer theory. It allows data to be housed in multiple servers globally.

Open blockchain networks are highly used to empower corporations by hosting and maintaining financial transactions with or without other financial institutions. Large transactions between firms and banks that generally take a few days and cost a commission now can be replaced with simple fast transactional protocols through blockchain networks. For these corporations, blockchain also ensures transparency in transactions and creates secure communication networks which work almost in real-time.

Blockchain technology is being adopted for network development and many new pilot projects within a huge number of industries and has been estimated to be generating more than 10.6 billion dollars in revenue by the year 2023.

Blockchain technology is built of three main elements:

  1. Blocks

Blocks are where the data related to the blockchain network is recorded permanently. The block contains a percentage or all of the newest financial transactions that have not been entered into the records yet. Thus, a block is a part of the distributed ledger or records. All the transactions executed during a specific period of time are recorded into these blocks which set up the blockchain network.

Blocks are therefore permanent records that, once generated, cannot be removed, changed, or altered. A block represents the current data and acts as a provenance for digital assets. Every time, a block is completed, it is followed by a new block which is entered into the blockchain and the old one becomes a part of the past records. The finished block is a record of the transactions and is permanently attached to it. Each block houses the records of all the transactions. This makes it impossible for any user to hack into or manipulate the transaction data which is previously recorded.

  1. Mining

Blockchain mining is a peer-to-peer computer process used for validating new transactions. Mining helps in securing and verifying blockchain transactions. This process involves Blockchain miners who keep adding and verifying transaction data to a blockchain network’s global digital asset provenance. Blockchain miners are connected to each other via the network forming a secure chain.

Miners use specialized software to solve the complex mathematical problem of finding a nonce that generates an accepted hash.

Making any change to a block in a blockchain requires the user to again not just mine the block but every single block that follows. This makes it extremely hard for individual entities with their own benefit in mind to control or hack blockchain technology. Once a block gets securely mined, this change is verified by the nodes which are connected with the network.

  1. Nodes

Decentralization is one of the fundamental concepts of blockchain technology. An individual or a group is not allowed to own or control the chain. Blockchain networks function on the basis of multiple computers or systems, known as nodes maintaining copies of the blockchain acting as a transparent distributed ledger that everyone can see.

Each computer or electronic device has a copy of the current blockchain in the blockchain network, and all the devices must approve all the new blocks which are mined, otherwise, the chain cannot be updated leading to the block not being verified. Blockchains are known for their transparency, and every single transaction in the distributed ledger can easily be verified and viewed. Each node is assigned a unique identification number that is alphanumeric in nature and is used to show all the transactions that belong to that member of the network.

What is a blockchain developer?

A blockchain developer extensively has a hold over blockchain technology and distributed ledger technology. Blockchain developers are expected to develop blockchain-powered systems and maintain the blockchain network for the organization they belong to.

A blockchain developer will have a specific set of skills that range from networking and data structures to having a good understanding of algorithms and cryptography. Generally, these developers have experience working on any existing open-source networks like Ethereum, Stellar, Litecoin, or the famous Bitcoin cryptocurrency. Experienced blockchain developers also can build on private blockchain networks or develop new projects.

How to become one?

In order to be a blockchain developer, a good blockchain course from a reputable institute along with additional skills in peer-to-peer technology, advanced algorithms, and data science is advised. Organizations demand blockchain developers to also have experience with already established blockchain networks. If one wants, he or she can follow up with another advanced highly specialized blockchain course to be more alluring to companies who are looking to invite blockchain developers for their projects.

With the growing need for super-fast transactions and the decentralization of personal finances, blockchain technology is picking up the pace as the forthcoming financial networking system to depend on and invest resources in. Many corporations are in dire need of blockchain networking expertise and are looking for highly skilled developers. Blockchain technology is something to keep in mind when thinking about specialization or future projects.
