A graduate of PICT, Krishna Upadhyaya worked at Accenture for a few months before landing an opportunity at Deqode, a business solutions company that leverages cutting-edge technologies in solving business problems. When the whole world was frenzy about cryptocurrencies, and smart contracts, Krishna found himself another opportunity to work with a startup company which later became a leading layer 2 solution for Ethereum network called Polygon. In this session, Krishna talks about how he thinks blockchain can re-invent the world, what are some industry practices for hiring blockchain developers, and what the future holds for blockchain. Here are a few takeaways from the session:

---

Q. What is blockchain?

Krishna: Blockchain is a technology that can improve all web2 applications (e-commerce, online gaming, money transactions, and so on) by establishing a distributed and decentralized network in which no single entity has complete control over the application's operation. Because everything that happens on a blockchain is immutable, it can provide greater security and privacy for users.

Q. How do I make the transition from IT to the blockchain industry?

Krishna: There are numerous companies (startups and multinational corporations) that provide blockchain solutions for various businesses. These companies are primarily looking for people with experience or knowledge of blockchain, Solidity, Golang, and Ethereum, but not exclusively. It's the problem-solving ability that matters most.

Q. What role does an internship play in landing a job at a blockchain start-up?

Krishna: Internships are simply a way for you to gain experience before entering a specific industry or a company. If you know what industry you want to work in and what type of job you want to do, it all boils down to one question: Do you have the necessary skills? You may have a computer science background, a non-computer science background, or have never done an internship before. All that is required of you are the skills that the company seeks. In most cases, a startup company looks for problem solvers who are willing to put in the effort until the problem is resolved.

Q. What are some myths about blockchain?

Krishna: There are a lot of myths and misconceptions about blockchain, so it's important to understand what's true and what's not.

1. Cryptocurrency is not the same thing as blockchain. Cryptocurrency uses blockchain technology to create a currency system that can be used to secure transactions across multiple networks.

2. There is no need for an advanced degree to work with blockchain. You can learn quickly and begin working on the blockchain if you are good at math and have problem-solving ability.

Q. What role does blockchain play in shaping the future of the world?

Krishna: Blockchain is still in its infancy. There's a lot more to learn and put into practice. Many startups have sprung up in an attempt to transform present web2 practices into web3 practices utilizing blockchain. One such example is utilizing blockchain technology for electoral voting. If implemented, people will be able to vote from the comfort of their homes.

There are a lot of applications that haven't been explored yet. The coming years will be really interesting, and if someone wants to build a company that wishes to last for at least 3-4 decades, I would advocate blockchain as the foundation technology.

There's nothing but trust that runs the world and blockchain is one idea that's disrupting the very concept of it. Blockchain has tremendous potential for personal privacy and data protection. However, the need for coordination with governments, businesses, people, and regulatory bodies is required to make it a reality.
