Blockchain is a buzzword that you would probably have heard somewhere.
Although this technology is around us for a decade, it has become a topic of discussion in the last couple of years.
It has the power to revolutionize the digital world. Emerging from fintech (Finance technology) institutions, it is spreading in different domains like advertising, utility, healthcare, etc., and different countries worldwide.
People have started recognizing Blockchain’s potential, and many of them have started adopting Blockchain-based apps to process transactions and payment acceptance in Bitcoin and other cryptocurrencies.
ABI Research forecasts Blockchain revenue to soar higher by 2023 and reach US$10.6 billion.
Due to increased adoption and awareness about Blockchain, the demand for individuals with Blockchain skills is likely to increase in the upcoming years.
So, are you curious about Blockchain along with related technologies?
If yes, then this article is for you!
Here, you will find the resources to learn all about Blockchain and get certified as well.
What is Blockchain?
Blockchain is a digital, immutable, and shared ledger that records transactions and tracks assets in a distributed network.
Think of these transactional records as the ‘block’ and interconnected network of databases as the ‘chain’. And think of this storage as the ‘digital ledger’.
Blockchain is a kind of Distributed Ledger Technology (DLT). In the world of Blockchain, an asset could be tangible or intangible. Tangibles are things like a car, house, a piece of land, etc., while intangible things could be copyrights, patents, intellectual property, etc.
You can trade and track anything that has value over a Blockchain network while reducing costs and risks.
Let’s take the example of Google Docs. You can create and ‘distribute’ it with people instead of transferring or copying it. Anyone with permission can access this document, view it, and modify real-time changes in a decentralized environment simultaneously.
How does it work?
- Each transaction gets recorded as a data block: The transactions display the asset movement, and the block carries information of an asset.
- Each block connects with the next one in a chain: data blocks form a data chain as the asset moves places. The blocks also confirm the sequence and time of transactions accurately while linking with one another to prevent alteration or insertion of a new block between existing blocks.
- Transactions block together, forming an irreversible data chain or ‘Blockchain’. Here, every additional block provides better strength to the previous block’s verification and for the whole Blockchain itself.
It makes the chain immutable and declines the possibility of malicious activities from entering into the ledger. Thus, it builds a secure network with greater transparency that members could trust.
Advantages of Blockchain
Business operations involve so many repetitive tasks, record keeping, and 3rd-party validations. Not to mention, record-keeping is vulnerable to cyberattacks and frauds—additionally, data verification impacts due to limited transparency.
To add fuel to the fire, data volumes increase with the arrival of digital technologies like IoT. Don’t worry; Blockchain has the power to handle all of these problems and provide benefits like:
Transactions and data remain safe with Blockchain as they are immutable and recorded permanently. Verification over data accuracy is a must and required from every network member. No one can delete any record or transaction. Hence, data is safe and secure.
As every member is aware of the transactions’ full information, it fuels transparency, unlike other types of transactions.
A decentralized ledger allows no one to control the information. Every member in the network can understand what’s going on in the network and timely and accurate data, building trust.
As the distributed ledger gets shared with each member, record keeping and reconciliations that waste time is eliminated. Transaction speed is further increased with a set of rules known as the smart contract, which could be stored over the Blockchain and then executed automatically.
This is all about Blockchain and its exclusive benefits, and this technology is creating new possibilities for businesses and individuals alike, reducing costs and increasing efficiency.
This is why Blockchain witnesses wider adoption in various industry verticals these days. That said, it makes sense for people to learn Blockchain and gain the skills to gain exciting career opportunities.
