Some quick highlights on what stood out to us!
The new year is here, and it was a significant one for blockchain. We wanted to take a quick look at the most exciting CorDapps we came upon over the past year.
The ones worth highlighting here are predicated on what our team thought were great ideas, practical use-cases, and ways to use corda that we just wouldn’t have expected.
One honourable mention I wanted to make is the snakes and ladders CorDapp by @iashutoshmeher. Ashutosh is one of our developer evangelists, and when he commits to building a CorDapp he does not disappoint! His CorDapp was a full implementation of snakes and ladders constructed on top of Corda so that players could use Corda to be sure of no funny business!
It uses a Tomcat web server to host the game from the Corda node itself and allows players to trigger Corda transactions that update the game state from within the browser.
You can find a link to Ashutosh’s CorDapp here.
The idea is to use Corda as a broker for information between universities and students who are relocating to university. With a blockchain as the data broker between these parties, the entire process can be streamlined for the students relocating. Nicely done!
Curious to take a look at the code? Find it on GitHub here.
The next CorDapp on our list was the decentralized corpus manager by R3 Solutions engineer @JonathanScialpi!
The project’s idea is to use Corda as a broker for crowdsourcing data for machine learning models. It uses Corda contract verification to ensure that corpus updates are valid and preserve the privacy of the crowdsourcers of the data.
Before I jump into our top CorDapp, some notable mention is due to a couple of standout moments for CorDapps in 2020:
It probably won’t surprise you to see this here if you were a part of the R3 Insuretech challenge earlier this year, as this was the challenge winner. This CorDapp was designed as a fraud detection platform for the insurance market. The idea here is to solve the “double-dipping” problem. They do it using secure computing with Conclave, Corda, and a mix of artificial intelligence tooling to ensure that the same claim can never be submitted twice.
The team documented a comprehensive process their tool is using. It uses a combination of Corda, fuzzy matching, public data, and date matching to be sure that they’ve got a match on the same claim being made multiple times. Double dipping is a critical and fascinating problem for the industry, and I look forward to seeing them solve it.
You can find out more about CLAIMSHARE from their article on it here.
More honorable mentions are also deserved for the teams that came in as runners-up in that challenge:
