How does blockchain work? A new, student-led group wants to show you. by Peter Ramjug May 27, 2021 Share Mastodon Facebook LinkedIn Twitter If you want to see where the growth opportunities are for the next 10 to 20 years, it’s going to be blockchain technology,’ says graduate student David Hsu, who co-founded Northeastern’s new blockchain club.

The Northeastern Blockchain Organization gets up and running in the fall of 2021 to share knowledge about blockchain technology’s potential to expand beyond digital currencies into mortgages and other contracts, according to club founders David Hsu and Bennett Thompson. ‘Throughout history, money was always pegged to a hard asset. Now that we are moving into the digital age, I don’t see why money couldn’t be pegged to a digital asset,’ says cryptocurrency investor and graduate student David Hsu.

When the blocks are filled, they are chained onto the previous block, forming a chain of data. All new information that follows the last block is compiled into a new block that will also be added to the chain once it is filled, and so on. After a block has been added to the end of the blockchain, it is difficult to go back and alter the contents, making it a secure and anonymous way to conduct transactions. For example, Colonial Pipeline paid hackers a ransom in bitcoin after a cyberattack crippled gas delivery systems and led to long lines at filling stations in portions of the Southeastern United States. Blockchain is increasingly capturing the attention of banks like JP Morgan and Wells Fargo, as well as venture capital firms, global money manager firms, and transnational companies. “If you look at IBM, Microsoft, Google, and a lot of the big venture capitalist firms, they all have dedicated crypto blockchain arms,” says Hsu, who is pursuing a graduate degree in computer science at Northeastern. Hsu worked at Boston-based Wellington Management, a global financial services firm that has hired more software developers in the last three years than any other position, to write the code that powers blockchains. Northeastern student Bennett Thompson, who is studying computer science and business, predicts blockchain technology will be bigger than digital payments and other aspects of the financial technology market.

They also want to give students an outlet where they can roll up their sleeves and learn how to write code. “Working on blockchain projects is a lot different than just watching YouTube videos,” he says. Figuring out the inner workings of blockchain is what initially ignited Thompson’s interest. After digital payments first captured his attention, he will be entering his second year in the fall to continue his computer science and business studies. Thompson is also involved with Disrupt, the university’s financial technology collaborative, but he thinks blockchain will have a greater impact than fintech. He saw its potential when a guest speaker from a Boston venture capital firm spoke at a Disrupt meeting a few months ago about blockchain’s potential applications. “We had a pretty big turnout, and students were asking ‘What is blockchain?’ ‘What is crypto?’ and so we knew even back then that there was growing interest in this space,” says Thompson, who invests in bitcoin, ether, helium, and other digital currencies. He says the blockchain club is taking a broader approach than just internet coins. Programming will focus on education, including events such as outside speakers and a bi-weekly forum for people to chat about what’s going on in the blockchain space.

Nodes are used by developers for building blockchain applications such as smart contracts, an agreement between two people in the form of computer code. “Smart contracts on blockchains…is an enormous game changer that every company will use,” billionaire investor Mark Cuban, who owns the Dallas Mavericks professional basketball team, told the Wall Street Journal. The blockchain club’s plans call for the hiring of a technology director to guide students through workshops on smart contract-writing, Hsu says. There will also be a focus on the academic side of blockchain research, which will be led by a doctoral student, Lucianna Kiffer, and involve technical white papers and academic research. Faculty from Northeastern and other universities will likely be invited to talk about their research. “That gives students the ability to understand the academic and technical underpinnings of blockchain but also have an opportunity for them to interact with professors,” Hsu says. The group held its first informal meet-up event in late May to discuss collectible digital assets such as photos and video clips called nonfungible tokens, better known as NFTs. Twitter CEO Jack Dorsey sold his first tweet as an NFT for almost $3 million earlier this year. Even as the cryptomarket is undergoing another round of volatility, Hsu and Thompson believe it is here to stay. “Throughout history, money was always pegged to a hard asset,” Hsu says. “Now that we are moving into the digital age, I don’t see why money couldn’t be pegged to a digital asset.” For media inquiries, please contact firstname.lastname@example.org.
