Bitcoin SV Hackathon semi-finalists explore the unique capabilities of BSV blockchain

A shortlist of six semi-finalists has been announced for the fourth Bitcoin SV Hackathon, each of whom demonstrate the unique capabilities of the BSV blockchain through their exciting and experimental entries. The theme for this year’s Hackathon is ‘peer-to-peer’ (P2P) applications, with competitors tasked with building an application or service on the BSV blockchain that leverages the recently released SPV Channels solution as well as the Merchant API (mAPI).

The fourth Bitcoin SV Hackathon kicked off on June 14 and offered participants an extended virtual coding round of six-weeks that allowed them to build out more viable and complete products. Now that the coding round has closed and evaluation is underway, Bitcoin Association has announced a shortlist of six semi-finalists, from which three finalists will be selected.

Competitors in the fourth Bitcoin SV Hackathon explored a range of applications and solutions built on SPV Channels and mAPI, demonstrating the high calibre of services that are enabled by the unbounded scaling and unique capabilities of the BSV blockchain. This year’s theme was especially challenging, but entrants have once again excelled in their implementation of cutting-edge technologies to build an impressive array of applications.

‘This iteration of the Bitcoin SV Hackathon has once again turned in numerous strong entries, each with a unique take on how best to leverage the peer-to-peer aspects of Bitcoin’s original design and the BSV network’s new SPV Channels implementation of P2P capabilities,’ says Bitcoin Association Founding President Jimmy Nguyen.

‘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.’

Bitcoin Association announced that the following entries had been shortlisted as semi-finalists for the fourth Bitcoin SV 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.

The standard of entries for this year’s Bitcoin SV Hackathon has been exceptionally high, and nChain CTO Steve Shadders says he is impressed with the quality of the SPV Channels implementations they have seen so far.

‘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,’ Shadders says.

‘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.’

Once the three finalists have been selected from the shortlist above and announced on August 24, a representative from each of the three teams will be flown to present their submission live for final judging at CoinGeek New York in October (applicable travel rules and restrictions at the time permitting).

The finalists will compete for a share of a USD $100,000 prize pool payable in BSV – $50,000 for first place, $30,000 for second and $20,000 for third. Final placings will be determined by a combination of a final round judging panel and audience voting.

The fourth Bitcoin SV Hackathon is run by Bitcoin Association in partnership with leading enterprise blockchain research and development firm nChain, with sponsorship provided by digital currency conglomerate CoinGeek.
