What do people mean when they say the word Blockchain?
In recent times bitcoin was showing all its glory, reaching new highs setting new records, and most importantly, becoming the talk of the town. As for most people, it was seen as just a tool they could use to generate an extra buck or become a millionaire, and in this perplexity, they never stopped questioning what made it so special. What technology was this new currency using, which not only made it decentralized but also safe and secure, and unhackable?
It’s not their fault per se, as when people did build that curious bone and started reading about the magic behind this creation, for many, this technology felt alien. They came across new terminologies and methods, which made them learn and understand it enough to make small talk but not its actual meaning.
This technology was Blockchain technology. Blockchain, in layman’s terms, could be deemed as a system with information in the form of blocks, and these blocks are connected with each other, making china—a distributed network connected by nodes. The data collected in these blocks are stored digitally and then connected to a peer-to-peer network.
This network is the thing that makes blockchain decentralized; there is no centralized authority managing all the transactions but a network of people who all have to authorize the transaction for the transaction to go through.
Although the network can be accessible to anyone, the data is stored using cryptography, making it impossible to penetrate and alter. Once a transaction is green, it cannot be deleted or changed. Only more and more chains could be added to the existing ones.
What are the different types of blockchain network
Blockchain, as discussed, can be called and denoted as the next-generation technology. People have already started to realize the importance of this technology and find ways to mold this into something profitable. They wanted to upgrade from the old server-centered database and move on to the network of blockchain architecture, where instead of server approving, participants within the network maintain, approve, and update new entries.
The following are the types of Blockchain Network Architecture
This one could be called the OG blockchain, and as this is what started it all, this is a traditional form of blockchain. The network used here is public, and anyone who has access to the internet can authorize themselves as a node and join the network. Once authorized, these nodes or the users get access to the past and the current transactions. They then have the authority to verify or do a proof of work for incoming new blocks. The data recorded in this network is open, transparent, and available to whoever has an internet connection.
There can be many participants in these open-sourced networks, and more nodes guarantee a more secure network. Fake transaction or hiding an existing one is an impossible task as every node has an updated copy of the database at any given point in time
This network is mainly used in the cryptocurrency format, as while doing the proof of work, they can perform mining and mainly use this blockchain for mining and exchanging cryptocurrencies.
This network is used to transact and mine cryptocurrencies like Bitcoin, Litecoin, and Ethereum.
The initial idea of Blockchain is about making it a peer-to-peer network and not giving any centralized authority the power to approve the transaction; hence it is decentralized. It was a public network, and this never made people question the transaction’s security and safety. They were indeed hack proof.
But this did not stop organizations from fearing and questioning the chances of confidential data being made public and it being leaked.
This paved the way for creating a private blockchain network. A private blockchain network is a restrictive and permission-based network, and the authorisation of accessibility is under the hands of the controlling organization. Private Blockchain is a scalable network that can be scaled according to the companies’ needs. If they want a blockchain of only 30 nodes, it could be easily deployed. It provides organizations with flexibility.
This network uses the same technology that is being used in public networks with restrictions on the entry of users. This allows the organization to handle who is getting the authorization of the network and lessen the risk of data sharing with rivals. Private blockchain networks are deployed for supply chain management, ownership, digital identity, voting, etc.
Consortium Blockchain is a variation of a private blockchain network. It can be said to be a semi-decentralized network. We saw in private blockchain that the authority to manage the network is restricted to a single organization. They are the whole and sole. On the contrary, in the case of consortium blockchain, more than one organization is coming together in a network. In this network, more than one organization can work as a node, and they have the full authority to exchange information and mining.
Organizations of the government and banks use these kinds of networks. This helps them to share data with their selective other organizations and, at the same time, keep the network private and permission-based.
This blockchain network, as the name suggests, is a hybrid. This contains features of private as well as public. With this hybrid approach, users can decide what data they want to make public and what they want to make private, and that can determine who gets what. The information in this network can be set as a private, permission-based system or a public, non-permission-based system. A hybrid blockchain was created so the user could use both networks’ benefits and decide what part of the chain’s information they want to make public and what they want to keep private.
The data of private chains are verified within the system, but there is also an option for the users to make that data public.
With the help of a public network, the number of nodes verifying the transaction increases, and this helps to increase the transparency and security of the blockchain network, making it more secure.
What are all places where blockchain could and is being used?
According to an interview with coingeek, “How our timestamping mechanism was used in Bitcoin” Scientists Stuart Haber and W. Scott Stornetta stated how back In 1991, when they wanted a computationally practical solution for time-stamping digital documents so that they could not be backdated or tampered with once recorded. This led them to develop and introduce a system using the concept of a cryptographically secured chain of blocks to store the time-stamped documents.
In 2004 Hal Finney came up with a Reusable Proof Of Work system that was published in BSD-like licenses. In this Hal finney created a system that would work by receiving non-fungible hashcash based proof of work in return, created RSA-Signed that again could be transferred from person to person. Then in 2008 something big happened, as per bitcoin.org, an anonymous person or group named Satoshi Nakamoto published a white paper called Bitcoin: A Peer-to-Peer Electronic Cash System, and it was at this time that blockchain saw its first mainstream limelight.
At first, blockchain was seen as only a technology that would support cryptocurrencies and nothing much. This all changed when Ethereum was introduced.
This opened all new possibilities for businesses to try their hand in this new web3 technology.
When different blockchains were developed and Hyperledger blockchain networks were introduced, they sent an invitation to businesses to come and join them.
The business sees blockchain as a reliable way of storing data about other types of transactions as well.
It is also suggested by many that blockchain technology should be used in the voting process, making it impossible to rig the systems and data tampering.

Is blockchain actually as safe as they give credit for?
As advocated by many, blockchain is considered the most secure form of recording and storing translation and data. This technology provides decentralization, making it impossible to tamper with.
It reduces errors by eliminating the human factor and is cost-reducing as they eliminate third-party verification.
It can be said that this technology as of now is pretty solid, and with more and more updates, like private blockchain, hybrid blockchain, and more is making its usage more and more user-friendly.
Blockchain technology V/S Nature
Although with all the benefits that this technology brings forward, some drawbacks need to be addressed.
This Network consumes vast amounts of computational power.
This technology relies heavily on many computers doing a bunch of little calculations 24/7, which requires keeping these systems running all the time. Because of this, it uses an unimaginable amount of electricity, an amount of electricity enough to power a city or even small countries. No one can ignore the fact that this amount of consumption would go unnoticed and won’t leave behind carbon footprints. These carbon footprints are not a good sign for the planet; if something is not done in this scenario, the catastrophe it brings would be dire.
