Fourth BSV Hackathon Semi-Finalists Impress with P2P Applications

Reading Time: 2 mins

The six semi-finalists for the fourth BSV Hackathon have been announced, and proponents and judges of the blockchain competition have relayed that they were impressed with the final projects turned in, considering that the degree of difficulty of requirements have increased.

For this year, BSV Hackathon the overarching theme is peer-to-peer applications, and entrants are tasked to utilize the recently released SPV Channels and the Merchant API (mAPI) in the platform they are creating, while leveraging the powerful capabilities of the BSV blockchain, such as unbounded scalability and high throughput.

“Working with all-new technologies – just like we tasked participants in the 4th Bitcoin SV Hackathon with doing with SPV Channels – is never an easy proposition. But challenging situations often lead to innovative solutions, which we’ve certainly seen with the standard of entries in this year’s Hackathon. Having worked intimately on introducing the Bitcoin SV implementation of SPV Channels, I’ve been intrigued to see how developers would approach it—and for a first foray with this new technology, I’ve been impressed with the early returns we’ve seen so far,” nChain CTO and BSV Technical Standards Chairman Steve Shadders said.

“With a challenging theme and complex requirements to remind developers about the often-forgotten P2P aspect of Satoshi’s intended Bitcoin system, it’s been impressive to see the different approaches employed by our participants. I congratulate all the semi-finalists and look forward to seeing who are selected as the three finalists,” Jimmy Nguyen, founding president of Bitcoin Association, Switzerland-based global industry organization pushing for the enterprise adoption of the BSV blockchain, added.

Below are the impressive six semi-finalists for the fourth BSV Hackathon.


  • Alien Wallet (Tom Middleton) – Bitcoin SV wallet that leverages Simplified Payment Verification (SPV) as well as a pay-to-order hash function.
  • Bitcoin Phone (Joe Thomas) – Voice-over-Bitcoin protocol which can transmit audio between users over Bitcoin transactions by leveraging the non-finality of nSequence to enable close to real-time data streaming.
  • BitCommit (Gary Miller, Vince Miller) – Trustless fitness competition application that leverages both micropayments and smart contracts.
  • CATN8 (Marcel Gruber, Dave Foderick, Thor) – Micropayment-based online video streaming platform which offers a fully featured SPV wallet implementation.
  • TimeKet (Joonyeong Park, Youngjin Jang, Seyoung Jang) – Unique SPV wallet service which offers integrated systems for reservation and payment validation.
  • TKS Pnt (Meta Taro) – Point tokenisation system designed to be used by merchants and their customers.


Three finalists will be chosen from the list above, and one representative from each finalist will get a chance to present their final project in front of a live audience during the CoinGeek Conference that will be held at The Sheraton, Times Square in New York on October 5 to 7.

The winner will receive $50,000, while the second and third placers will take home $30,000 and $20,000 in BSV, for a total prize pool of $100,000. On top of these prizes, finalists also get the rare opportunity to interact with blockchain professionals and experts during the three-day conference, as well as meet potential investors.


The BSV Hackathon is a great stepping stone for innovators and developers to build their first applications, fine-tune them and eventually launch them. Blockchain integration firm Kyrt, incentive-based online review platform Britevue and promotion marketplace TonicPow are all running and earning applications that have come from previous BSV Hackathons.
