You should build an application that leverages the unique properties of Bitcoin SV:

  • Big blocks – high transaction volumes with low fees
  • SPV callbacks
  • Instant payment verification


Throughout the virtual competition period, moderators will communicate with you via Discord, the Devpost platform and email for all of the following:

  • Timing announcements
  • Videos from the organiser
  • Tips and tricks


During the competition period, assistance will be available from both the moderators and nChain staff.

  • If you need help, speak to a moderator via Discord who will find an appropriately skilled/knowledgeable person to assist you.
  • Zoom will be used if a video call is requested.
  • Please be aware that nChain staff are only guaranteed to be online during London, UK office hours. Outside of these hours, support will be provided on a best effort basis.
  • The nChain staff will be available primarily to give advice on the Bitcoin SV protocol and infrastructure. Questions regarding third-party tools, libraries, and APIs will be better directed towards other participants of this group or even in communications channels with other competitors.
  • nChain staff will be able to provide high-level advice, but cannot give specific advice about your project, design, or implementation. This is to ensure no one is given an unfair advantage.


Additional rules and eligibility exclusions

  • For teams, the team leader must be over the age of 18, although other team members may be younger than this. The team leader is the person who will be nominated to present the submission if selected as a finalist and receive any awarded prize. (Teams may elect to share an awarded prize among team members however they see fit).
  • Current employees and staff (including contractors) of nChain, Bitcoin Association, and CoinGeek may not enter the hackathon competition.
  • Previous top 3 finalists from Bitcoin Association Bitcoin SV Hackathons are excluded from entering another Bitcoin Association Bitcoin SV Hackathon for a period of one year following the final round of the competition in which they were a top 3 finalist.
  • Multiple entries from one individual or team are not permitted and are grounds for instant disqualification.



Code re-use:

  • The general idea of a hackathon is to produce a project from scratch during the competition period.
  • You may use any code libraries as part of your project, but they should be clearly separated (in a different directory) to your original code.
  • You may reuse code you have previously written for an unrelated project, however, this should be clearly declared in your explanatory notes. This should also be segregated in a separate directory to the entry code. Judges will factor this in and, if the project the code came from is deemed too similar to the submitted entry, a significantly higher standard will be expected. We would, therefore, encourage you to work on a new idea rather than building directly on an existing product.
  • Work product and material submitted for previous Bitcoin Association Hackathon entries cannot be resubmitted.

Bitcoin Association reserves the right to disqualify any entrant who does not adhere to the Bitcoin SV Hackathon rules applicable, and to anyone who gains an unfair advantage through fraud or unsportsmanlike conduct while participating in the hackathon.


After the Virtual Competition Period

A representative from each of the three finalists will be invited to present their entry at the next CoinGeek conference expected to take place in October 2021 (dates and location still to be finalized, and shall be referenced herein as the “CoinGeek conference - Q3 2021”). The representative will either be flown to the site of the CoinGeek conference – Q3 2021 or present their submission virtually – depending on what world travel circumstances allow at such time in light of the COVID-19 pandemic. Finalists may continue to develop their entries and presentations prior to the final presentation at the CoinGeek conference – Q3 2021.



All entrants agree that Bitcoin Association, CoinGeek and their affiliates have permission to use the entrant’s name, picture or likeness, biographical information, prize information, information, material, and screen captures about their submission to the Bitcoin SV Hackathon, and/or statements they make about the Hackathon on the Bitcoin Association, Coingeek.com and other websites and for publications for editorial, advertising, and publicity purposes, without compensation, to the extent permitted by applicable law.


Investment consideration

By entering the hackathon, all entrants agree to the following provision in the event they are selected as a top 3 finalist and therefore are considered a “Winner” of a Bitcoin SV Hackathon prize.

Winners agree that Calvin Ayre, Ayre Group CoinGeek and/or their affiliates will have the exclusive right up to and including June 30, 2022 to enter into negotiations with Winners for possible investment and to enter into any investment agreements for the project the Winners submitted in the Contest and any venture based thereon. Winners acknowledge there is no obligation for Calvin Ayre, Ayre Group, CoinGeek, and/or their affiliates to invest in Winners’ project submitted in the Contest or any associated venture.
