Last updated: 17 September 2026
These Terms and Conditions (“Terms”) are entered into by and between Logos Collective Association, Baarerstrasse 10, 6300 Zug, Switzerland (“Logos”, “we”, “us”) and any individual or legal entity participating in the λPrize Program, including by submitting any solution (“you”, “Participant”) (each a “Party” and together the “Parties”).
By making a Submission as part of the λPrize Program, you acknowledge that you have read, understood, and agree to be bound by these Terms and any applicable Prize specifications (“Specifications”).
You can contact us about these Terms in case you have any questions: ecosystem@logos.co.
This section sets out the nature of the λPrize Program and the Prizes and seeks to contextualise and provide Logos’ intention for the λPrize Program. All descriptions in this section are provided for context only and are further subject to the disclaimers and risk‑allocation provisions set out later in these Terms.
λPrize Program: Logos seeks to support and promote development on the Logos technology stack, which has been made available as open-source infrastructure for independent use by developers and the wider community. As such, Logos has developed the λPrize Program (“Program” or “λPrize”) is a voluntary, criteria-based, discretionary prize initiative where Participants may be awarded for independently developing and submitting innovative solutions that benefit the Logos ecosystem through reusable open-source work and credible “social-proof” of ecosystem progress.
Through the Program, participants may independently develop and submit innovative solutions for Artefacts that demonstrate the capabilities of the Logos technology stack and support its adoption.
Logos acts solely as the administrator of the Program, which includes, determining and setting out the relevant Specifications, evaluating and selecting a winning Submission, the award of a Prize amount and any other activities in support of the Program. Please also refer to the additional disclaimers around Logos (and its Affiliates’) role in clause 13 of these Terms.
Prizes: The Program comprises multiple prizes (each a “Prize”) for which Participants may be eligible and these are further described in the λPrize GitHub repository. Prizes are typically defined through an analysis of gaps in the Logos technology stack and its ecosystem. This analysis refers to categories of infrastructure and applications commonly found in mature blockchain systems and their ecosystems as well as the technical dependencies between components.
Prizes may also refer to different Prizes or its Specifications. These are referred to solely for the purposes of identifying criteria applicable to an Artefact of a Submission that may need to also be developed and included as part of a Submission for that Prize. Such references do not require nor direct a Participant to use, extend, modify or otherwise rely on any previous code, implementation, Artefact or Submission associated with the referenced Prize or Specification. Where such references are made, it is up to the Participant to determine how best to develop or incorporate an Artefact to satisfy the relevant Specifications of the current Prize, whether to develop it themselves or otherwise.
Please also refer to the conditions of the Prize in the Specification and also clauses 7 (Evaluation and judging) clause 8 (Prizes).
Specifications: Each Prize has a separate specification (“Specification”) which sets out, among others, its motivation, criteria, scope, the Prize amount and eligibility requirements. The Specifications are guided by existing approaches and implementations in other mature blockchain systems and their ecosystems, as well as by functional requirements particular to the Logos technology stack or perceived usefulness to the Logos ecosystem and community building on the Logos technology stack. Considerations may include open-source delivery, trust minimisation and a non-custodial design, however, these are indicative rather than exhaustive and any given Prize may reflect further or more specific considerations.
As such, Specifications may describe Prizes with a range of maturity levels, ranging from experimental prototypes and proofs-of-concept to production-ready or near-production-ready applications and integrations. Where the Specifications set out specific criteria, this is because such criteria may need to fulfill particular requirements, such as to satisfy particular technical requirements or ensure compatibility with the Logos technology stack, rather than to prescribe how a Submission should be implemented.
Where Specifications also include any “adoption-criteria”, it is a criteria through which Logos views will allow a Submission to demonstrate actual usefulness to not only the Logos technology stack but also to the wider community. As such, any adoption metrics are intended to demonstrate a Submissions’s real world-interest and the extent to which others are building on, testing, or experimenting with a submission. It does not imply anything about their security, reliability, fitness for any purpose and Logos does not guarantee anything about them.
The Specifications also helps guide Logos in determining whether a Submission has met the criteria within and as such, when Logos selects a winning Submission for that Prize, it only means that the Submission has met the stated technical or non-technical criteria for that Prize and nothing more.
In these terms, the following capitalised terms have the meaning set out below:
