‘Developer of Blockchain-based Service network gets $30M in funding.’
We all are acquainted with reading the news related to Blockchain. Not just because we want to, but they usually make up the headlines of the technology news section. But, have you ever asked yourself, what is Blockchain?
If we break the word ‘blockchain,’ we get two by-products, block, and chain. It reflects that the terms are somewhere linked in real-life too. Could it be a chain of blocks for storing information? Let’s deep dive in.
What is a Blockchain?
Let’s consider an analogy to explain the term Blockchain better. We all might have traveled by train at some point in our lives. The train is built using the main engine, and several compartments are joined together that work as a team. The engine then pulls up the other compartments together to your destination.
The same is the case with Blockchain. The word can be split into ‘Block’ and ‘Chain,’ which signifies that numerous blocks are chained together. As a definition, Blockchain is a database of blocks that holds transactions in a decentralized manner. It is distributed and considered as immutable when talking w.r.t. Security.
The Blockchain helps store the information in each block that can be easily distributed but doesn’t allow anyone to alter the transactions. Users can not delete or destroy the information already inside the blocks which are known as distributed ledger technology (DLT).
The block we talked about contains three elements: the data, nonce, and Hash. Data is the information kept inside the block. Hash is an algorithm that produces a unique sequence of characters (32 bytes). A nonce is an arbitrary number generated to ensure blockchain security.
The sequence of characters or Hash gets generated with the value entered in the block. The hash output will be completely different, even with minor data alterations. It ensures Security as each block stores the Hash of the previous block. Now you might be confident that Blockchain is the driving force of all cryptocurrencies.

What is Decentralization?
Decentralization is the process of transferring control and decision-making power to a distributed network. Contextually, this means there would be no central authority. Let us example this by taking an analogy of banks.
Banks follow a top-down approach working in a centralized manner. Databases containing information about the records, identities, and transactions are stored at a server, posing a potential threat of being hacked.
On the contrary, the databases of Blockchain are distributed across the network of computers. Each computer (or node) has access to every information of the block added since its birth.
Transparency in Blockchain
Decentralization made transparency possible on blockchain technology. Even if I am working in Antarctica, sitting with the penguins on my side (obviously, it is a hypothetical situation), I can view all the transactions with my personal computer or hover to the website blockchain explorers to see the addition of blocks.
Decentralization paired with security is what works as the best combination for blockchains. It narrows down our search to whether Blockchain is safe?
How safe is Blockchain?
Blockchain is known for the security level it provides to consumers. It is unmatchable!
The addition of blocks is done sequentially with the hash and timestamp of the previous block stored in the current block. Hash codes are created by a math function that encrypts the output file. Let’s understand it in simple terms.
A bank’s server can be hacked into easily as it has a centralized authority, resulting in information leaks (as much private as credit card info). If someone tries to break into the Blockchain, the block would not be accepted, as under checking by other nodes, the hash codes and timestamps would lead to the discarding of such a block.
Although, for doing altercations to the Blockchain, the hacker would have to gain access to 51% of the Blockchain network. It would require a vast sum of money and resources to deplete the value. Therefore, it is pointless even to try!
Blockchain Technology and Banks
Blockchains and banks are just poles apart. If you are already at this point of the article, even you could easily list out differences. We will brief you a little more.
The Blockchain provides privacy, contrary privacy in banks is just a hack away. The transactions are paced at much higher speeds, while banks take even days to perform. The transaction fees are lower, and transfers are easy to serve on the Blockchain.
Adoption of Blockchain Technology
Blockchain technologies have a very bright future ahead. The possibilities of blockchain implementation have spiked the graph where users could tap the energy to prevent any misuse.
With the growing climatic changes and the rapid adoption of automobiles, we need to track waste generation for a clean and green environment. Blockchain as a technology is helping municipalities to track and monitor the waste life-cycle efficiently.
Use cases of Blockchain
With the emergence of technological advancements, Blockchain has a stable foot on the ground, and you can find it almost in every field.
Blockchain technologies work 24*7. Forget about standing at the bank queues to transfer the funds or encash a cheque; Blockchain makes it possible within 15 minutes. Moreover, a comprehensive set of people are also active in trading blockchain products (like bitcoin).
Traditional currency involves the use of currency notes which the government and centralized bodies regulate. Blockchain makes it possible to hold it digitally at a safe, secure, and decentralized place.
People can easily save the land record details on a blockchain. It will remove the cumbersome process, save time, resources, and provide a fast, seamless experience.
- Smart contracts
A smart contract is a computer-operated transaction protocol that automatically executes and controls the events described in the agreement. Introducing them in a blockchain will help in the easy implementation of contracts.
Advantages of Blockchain
Apart from diving into the use-cases, Blockchain technology has tons of pros to list.
- Cost reductions
The cost to set up an institution is very high, plus you have to pay for taxes, lease, paperwork, legalities, etc. Consumers incur these costs in the form of transaction fees. Blockchain has a significantly lower transaction fee and is more feasible.
To err is to human,’ financial institutions are worked up by humans. It comes at the stake of errors which might result in loss of funds. Blockchain works on computer nodes; there is no room for mistakes.
Privacy is often compromised when we talk of companies working on centralized servers. Blockchain technologies have a unique selling point of a public key stored on the blocks instead of personal information, posing no threat to consumers.
- Banking the Unbanked
The banking institutions may sometimes deny access to their facilities on some factors. However, Blockchain doesn’t distinguish anyone. Everyone is welcome to transact and use it for personal or savings purposes, with just an internet connection and computer in handy.
Blockchain is very secure. Bitcoin is a popular cryptocurrency that facilitates transactions worth millions of dollars daily. Naturally, people wouldn’t have favored it without security and trust.
Disadvantages of Blockchain
As much as Blockchain receives appreciation in terms of its facilities, there is room for untouched disadvantages.
- Technological Costs
The costs are not for setting up a blockchain but for making them run at a pace. At present, verifying the bitcoin’s block (also known as proof of work) requires vast amounts of electricity. With the surge in rates, the transaction costs can go high. For the blockchains with no cryptocurrencies, miners would need some incentives for adding the blocks.
Not all blockchains are slow. Some blockchains can perform a million transactions in a minute, whereas bitcoin, which is the most popular, requires about 10 minutes to add a block.
- Government Regulations
Blockchain doesn’t have any regulations on them. However, restrictions on cryptocurrencies are country-specific. India and the US are still discussing how to regulate them while Germany & Dubai allow them to be traded and use legally.
Countries like South Korea and Japan allow their citizens to trade in Bitcoin and other cryptocurrencies. However, El Salvador has recognized Bitcoin as a legal tender.
- Illegal Work
Some cryptocurrencies were also active on the dark web to transact illegal products such as drugs, weapons, or smuggling. It needs to have Governmental intervention to stop such illicit trades.
So far from now, reading this article would have convinced most of you as Blockchain is a promising technology for the future.
As we are heading over to the digital age, where even food orders are done by a single tap, exploring the various use cases could be a bright side of the road. As countries are setting their foot to examine the fate of cryptocurrencies, we need to ensure the possible use cases they offer presently. The future of cryptocurrency in India looks bright based on the market, investors, and people willing to enter the cryptic space.

The Russian punk rock collective Pussy Riot plans to launch a DAO that will be promoting LGBTQ+ and women artists.
Russian punk rock collective Pussy Riot is planning to launch a DAO for LBTQ+ and women artists.
As the group’s co-founder Nadya Tolokonnikova told Cointelegraph, The DAO will be working on reducing the gender inequality that still marks the NFT space and, more broadly, the crypto industry.
Despite the large gender gap in crypto — around 60% of US crypto investors are white men according to a survey from August 2021 — Nadya is convinced that it is still early enough for Pussy Riot to make an impact.
“The NFT space is still so small, I feel that with a good enough effort you can actually change it”, she said.
Nadya is already using her follower base to promote the work of women and LGBTQ+ artists and connect them with potential collectors. The DAO will continue doing so but on a larger scale.
“We are going to hire a whole team who will be creating educational material for girls who want to enter the space”, said Nadya.
Punk rock group Pussy Riot has gained worldwide popularity for its provocative performances and criticism of the Russian government.
Last year, Pussy Riot started using NFTs to raise money for social causes. In March 2021, the video of their music single “Panic Attack” sold for a total of 178 ETH as an NFT series. Most of the money was then donated to victims of domestic violence.
“I wanted to bring large human rights and charitable components to NFTs”, Nadya said.
