How UBRI Supports Critical New Research into Blockchain Anonymity


By its decentralized nature, a blockchain is extraordinarily troublesome to hack. That doesn’t imply that digital property and wallets constructed on the expertise are invulnerable, which is why the organizations behind them spend a lot time fascinated by safety.

However, according to Stefanie Roos of the Delft University of Technology within the Netherlands, the blockchain trade will quickly have to present equal consideration to privateness considerations. Though she admits this concept could come as a shock to these people who benefit from the anonymity of Bitcoin.

“Because you don’t have to enter your real name, people believe that Bitcoin is very privacy preserving,” says Stefanie. “But when someone keeps reusing the same information, it’s possible to track everything they do. If you can link that profile to a real person then you can see all their activity.”

Stefanie is assistant professor for distributed techniques on the college, having accomplished an award-winning PhD thesis on the topic earlier than working at Canada’s University of Waterloo. She’s properly versed in utilizing decentralized expertise for funds having developed SpeedyMurmurs, a peer-to-peer system that takes a path-based transaction strategy just like Bitcoin’s Lightning Network.

Today, a lot of her focus is on methods to create versatile anonymity for blockchain-based funds, particularly for enterprise transactions. Businesses paying suppliers on a public blockchain might inadvertently reveal particulars about services or products they’re creating to opponents. While personal blockchain are the apparent answer, Stefanie believes public expertise with acceptable anonymity could possibly be extra useful.

“Think of systems where anonymity is temporal,” she says. “You get privacy for the time that you need it. If you want to have transparency later on, you can reveal the relevant cryptographic keys to demonstrate that you complied with regulatory requirements, show off your high-quality suppliers or to prove a patent case.”

While people hardly ever have the identical confidentiality wants as companies, Stefanie believes shoppers will quickly understand the necessity for privateness across the funds they make on public blockchains.

“People won’t want others seeing what they buy or sell,” predicts Stefanie. “That has huge potential for blockchain bullying. Imagine teenagers knowing each other’s transaction history, being able to see who has the most expensive clothes or shoes. Some people may not want others to know that they get government benefits. We have to make sure that these systems preserve our privacy.”

Some of Stefanie’s college students are anonymity on the XRP Ledger, as a part of Ripple’s University Blockchain Research Initiative (UBRI). Aided by UBRI grants, one scholar is wanting on the Ledger’s consensus algorithms, whereas one other is engaged on a brand new approach of testing for safety vulnerabilities when a theoretical blockchain mannequin is translated to code on sophisticated, giant scale tasks.

“The two students obviously benefit from the UBRI grant, which will fund their PhDs,” she says. “But they’re also able to talk with people at Ripple about their ideas and whether they could actually be part of the system. It’s great motivation for this type of project, if you know there is a chance it can become a real product.”

Delft’s UBRI connection additionally advantages these attending the college’s blockchain Masters course. Class numbers are intentionally small in order that college students can’t solely be taught the speculation of blockchain however implement tasks associated to totally different purposes.

“Our links with UBRI have been useful for the students implementing applications on top of the XRP Ledger,” concludes Stefanie. “One team created a bill splitting system, where one person pays a bill in the restaurant and the rest settle it using the XRP Ledger. It’s just sad that the coronavirus shut down all the restaurants, but hopefully they can test the theory in a real-world scenario soon.”
