What is Blockchain?
As the name suggests, Blockchain literally means a chain of blocks that can store any form of information (date, time, location, etc.) of digital transactions. It is a public, decentralized, and distributed ledger used to store and record digital transactions in a peer-to-peer network.
Since it is decentralized, there’s no single authority managing or handling a blockchain network. Instead, it is managed and validated by all the participants in a network. This feature makes it nearly impossible for any third party or outsider to hack into a blockchain and tamper with the data stored in it. Learn more about the functionality of blockchain technology.
What makes Blockchain a compelling technology?
There are several reasons why Blockchain has spiraled its way to the top tech trends in the market right now:
1. It is highly secure and immutable – Cyberattacks and cybercrimes have skyrocketed in the last decade, making data a vulnerable asset for both businesses and customers. However, a blockchain helps solve this problem since storing and validating data in a blockchain is highly complex and protected via cryptography. Thus, it is immutable and tamper-proof.
2. It is transparent – Since Blockchain is a public ledger, anyone can view the data stored in a blockchain. All the parties can access and view the same information. Each participant in a blockchain network can access an individual copy of the Blockchain protected by a unique cryptographic key. Also, this information is spread across a vast network, which makes it difficult to manipulate it. Anyone wishing to make even a minute change in one block’s records will need to modify each copy of the blockchain network.
3. It facilitates speedy transactions – With Blockchain, you can instantly send and receive any kind of transaction, be it financial or sharing data over a network. A blockchain officially has no downtime whatsoever.

4. It increases financial efficiency – As mentioned before, transactions in a blockchain occur without third party involvement. All transactions take place according to the agreed-upon sanctions of the parties involved. Since Blockchain eliminates the concept of intermediaries, the transactions are smooth, private, and cost-efficient.
5. It eliminates the possibility of fraud – Being an open-source ledger, all transactions in a blockchain are visible to all peers. Hence, the network participants can quickly identify if anyone tries to manipulate or violate the data and if any fraudulent actions occur.

Industries Using Blockchain
Here are five industries that are already leveraging Blockchain:
Healthcare institutions have to handle and manage large volumes of sensitive medical and patient data. Usually, this information is stored in a central repository making it an easy target for hackers. However, healthcare providers are now storing medical data across a decentralized and distributed network with blockchain tech. This increases privacy and keeps sensitive data safe from any violations.
Pharma companies use blockchain tech to take the track-and-trace serialization process to the next level by enhancing real-time supply chain transparency and eliminating erroneous data. By making the process seamless and transparent, pharma companies can minimize costs and improve system security.
3. Food industry
Food supply companies are using Blockchain to enhance and regulate food safety. By incorporating blockchain technology in the food supply chain, all food suppliers, processors, regulators, vendors, retailers, and customers can access the information about the origin and sourcing of food items. All the transactions are transparent. Blockchain not only ensures that food items are sourced ethically and legally, but it also helps companies to trace contaminated foods, allowing them to eliminate them from their inventory.
4. Asset management
Blockchain is fast becoming an integral part of asset management, especially for managing tangible/intangible and complex assets like real estate. Typically, these assets are constrained by determining factors like liquidity and investment size. Thanks to Blockchain, asset management firms can easily tokenize, section, and distribute the assets securely with minimal friction and management costs.

5. Capital markets
The modern capital market is regulated by stringent laws, rules, and risks. One of the most compelling risks involved in capital markets is high operational costs, which hinders companies’ profit margin and harms potential customers by raising the entry bar. Blockchain can solve this challenge by optimizing the back-end operation costs via a permissioned, immutable, and single shared ledger accessible to the capital market stakeholders.
Thanks to the security and transparency that it offers, Blockchain is making its way into many industries. This is further pushing the demand for blockchain experts across different sectors.

What is Hyperledger?
Hyperledger, created by the Linux Foundation in 2016, is a global enterprise blockchain project to create distributed ledgers using blockchain technology. It offers necessary frameworks, guidelines, standards, tools to build blockchain-related applications and has had the support of prominent organizations such as IBM, Intel, American Express, and many others. Hyperlink-based technology works using five layers: consensus, smart contract, communication, API, and identity management services. Some of the famous projects offered by Hyperledger are Hyperledger Sawtooth, Hyperledger Fabric, Hyperledger Indy, Hyperledger Besu, etc.
What are Block Identifiers?
The role of Block Identifiers is basically to identify a particular block. A cryptographic hash identifies each block. A digital signature is created using the SHA256 cryptographic hash algorithm by hashing the block header twice. Every block hash is unique and is created using the previous block, also known as the parent block. It means every block contains its parent’s hash inside its header, and the sequence of linking hashes with their previous block creates a chain. This chain is known as the genesis block. Each parent block can have many following blocks, although only one block remains at the end.
What is Crypto Token, and how is it different from Crypto Coins?
Tokens, usually confused with Crypto Coins, are tradable assets with multiple utilities. Crypto tokens can be considered digital assets stored on a blockchain. Unlike cryptocurrencies which are used to make payments, crypto tokens can be used for many things. They can be held as a store of value, act as a medium of exchange, etc. Another fundamental difference between them is that crypto tokens don’t have their own blockchains; instead, they run on the blockchains of Crypto coins. Tokens are proof of ownership, which means it has to be physically moved from one place to another in case of transfer of ownership. One example can be NFTs which are proof of ownership and whose transfer of ownership has to be transferred manually.
