1. Applicability

These general conditions for participants of the Odyssey Hackathon 2019 are applicable to all (legal) relationships DBH in connection with the Hackathon (the ‘
Participants Conditions’). All participants of the Odyssey Hackathon 2019 (‘Participants’) are bound by the Participants Conditions. Participants are obliged to (digitally) agree with a copy of the Participants Conditions prior to the Hackathon.

The ‘Odyssey Hackathon Community General Terms and Conditions of Use’, which are to be consulted and saved through (the ‘
General Terms’) are applicable to the Participants Conditions as well. In case of a contradiction between the Participants Conditions and the General Terms, the provision in the Participants Conditions will prevail.

2. The Hackathon

DBH organises a full year programme – pre-hack meetups, a hackathon and post-hack activities – in The Netherlands with respect to blockchain & AI technology which will be called the
Odyssey Hackathon 2019.

Prior to the hackathon from April 11  until April 15 2019 (the ‘
Hackathon’) several Pre-hack meetups will take place where a partner or sponsor (including a party presenting and submitting a Track) of the Hackathon, other than a Participant (‘Partner’) will present themselves or their Track (the ‘Pre-hack meetups’). Participants and Partners will meet each other and discuss and share developments regarding blockchain & AI technology.

At the Pre-hack meet-ups or at the start of the Hackathon, (some) Partners will present a practical problem which they think could be (partly) solved by using blockchain & AI technology  or a theme (the ‘

A Team of Participants will provide the Partner who introduced the Track with possible solutions for his practical problem by using blockchain & AI technology at the end of the Hackathon. Software will be provided by (some) Partners and can be used by the Teams. The solutions shall be judged by the Jury. The Jury will unilaterally decide which Team(s) provided the best solution.

A solution provided by a Team should be conceptually original, non-existent and new and should be able to be implemented according to common and regular measures. Existing solutions are only to be used by integration into a new solution. The solution needs to be functional, in order to be judged by the Jury.

The Hackathon will last 5 days. The Hackathon is a closed meeting. No other persons or organisations than the Participants and Partners may join or visit the Hackathon, unless DBH explicitly gives permission thereto.

The Participants and Partners shall endeavour to further develop the solutions after the Hackathon (the ‘
Post-hack)’. During 3 months after the Hackathon, the winning Team(s) shall decide jointly and in consultation with the respective Partner who introduced the Track whether it is possible to actually apply the solution or whether it is possible to scale it up.

The winning Teams shall present their solution at showcase conferences during the Post-hack when DBH invites them to do.

6.1 Own application


The Participant declares to comply with all applicable laws and regulations.

Each Participant guarantees, by signing up, that he/she (together with the Team) is the creator of the solution and that the solution does not breach any intellectual property rights of third parties and indemnifies the Partners and DBH from any third party claims.


7. Use of datasets by Participants


Participant is given access to software (from Partners), including datasets and API’s (‘Application Programming Interfaces’ or ‘API’ means technology, which may include object code, software libraries, software tools, sample source code, published specifications and documentation) of the relevant Partners (the ‘
Software’). The Partners grant Participants the non-assignable, non-sub licensable and non-exclusive right to use the Software, exclusively and only for the purpose and duration of the Hackathon. Partners may have individual general conditions for the use of the Software. Partners are allowed to impose those and other (additional) conditions for the use of the Software, which conditions will prevail over these Participants Conditions in case of contradiction.

The intellectual property rights of the Software (from Partners) belongs to the Partners at all times. Access to the Software shall not grant a Participant any intellectual property right regarding the Software.

The Software shall only be used by Participant(s) for the development of a solution during the Hackathon and shall not be shared with or provided to any third party. After the Hackathon, Participants are prohibited to use, copy, open, or share – in any way – the Software with third parties, unless this third party has signed a separate written agreement in which the Partner who is the owner of the Software that the Participants want to use, gives permission to the Participant to use the Software. Contents in cache or stand-alone copies of Software should be destroyed within two weeks after the Hackathon.

Each Participant is individually responsible for the safety and confidentiality of the Software it is using during the Hackathon. 

Participant will inform, without any delay, the relevant Partner of any loss or unauthorized use of the Software including any breach of these Participants Conditions. 

Software containing anonymous and/or traceable data to individual persons/organisations is not allowed to be combined with other Software in such a way that it may lead – directly or indirectly – to identification of one or more individual persons or organisations.


8. Intellectual property


The intellectual property rights based on the solution, developed by a Participant or its Team during the Hackathon, stays with the Team (all Participants in the team combined) and not with any Participant individually, except when a team is fully delegated by an employer, in which case the intellectual property rights will accrue to the employer, except when the employer and employee have made other arrangements.

Teams must follow these guidelines when building their solution: depending on the indications at ‘open source or proprietary’ made on the challenge page of their challenge they must
