The Rules of the JAM Prize

Third-party libraries for cryptographic primitives (erasure-coding, Bandersnatch, Ed25519), codecs (e.g. SCALE), and networking (e.g. QUIC) are acceptable.

Only languages defined in one of the language sets are eligible for the prize.

For languages not in the set, an application may be made, including the set you propose and arguments why that set is sensible and why the language is sufficiently different from the others to be valuable.

Code must be idiomatic for languages which define idiom.

Gas, trie/DB, signature-verification, and availability (EC/DB) performance tests are requirements and will be run on standard hardware.

Clean-room implementation using the Graypaper and public implementers' channel as the only resources.

Any JAM-implementation code which is viewed before or during implementation must be declared.

Relevant private (not in the public implementers' channel) conversations with other implementers must be declared and summarised in reports to the Fellowship.

The prize may be reduced in case collusion may be sufficient to reduce network security.

If concerned, then declarations may be stated up-front and the maximum reduction set; as long as declarations are accurate and no further collusion happens, then the reduction proportion will be the maximum.

An interview may be requested by the Web3 Foundation after submission to ensure the authors are legitimate.

Following the accepted completion of each milestone, teams may nominate one Fellowship candidate/member to be promoted directly to rank III and (optionally) a second candidate/member to rank II (more information about the ranks can be found on the Polkadot Fellowship Manifesto).

A clear Git history and public, credibly timestamped commits are necessary in order to help evidence organic code development by the team/s.

Timestamps may be by virtue of pushing code to GitHub on a timely basis.

For code developed in private, commit hashes should be placed, in a timely fashion, on a major public blockchain and readily visible on a block explorer.

Apparent lack of originality, undeclared collusion, and suspected plagiarism may result in disqualification entirely at the discretion of the judges.

Appeals may be made through a governance referendum on the Polkadot Wish For Change track, and the result will be respected by Polkadot Fellowship.

Implementations must pass all relevant public and private conformance/performance tests. These will be shared in the near future.

Prizes are paid no earlier than the ratification by the Polkadot Fellowship of version 1.0 of the JAM protocol. Payment of the prize by the Web3.0 Foundation is conditional upon the successful completion of all KYC/AML processes.

Prizes are paid to the earliest Polkadot/Kusama account IDs stated in the repository's README. In the case of a tie, payment is split equally. Local (Swiss) law requires that Web3.0 Foundation take KYC/AML information on the recipient together with proof of account control.

The prize pool is limited. Prizes will be awarded on a first-come, first-served basis, based on the order of valid submissions received. Once the prize pool is exhausted, no further prizes will be awarded, regardless of the number of participants or the quality of submissions. Prize pools may be redistributed and reallocated if a pot is nearing depletion, subject to the following conditions: (i) a 3-month notice period must be provided and (ii) no more than 25% of the prize pool may be scheduled for redistribution at any one time.

Each team is only allowed to work on one implementation.

Participants warrant that their submissions do not violate the intellectual property rights of any third party. Participants who are in an employment relationship are advised to ensure that their submissions do not infringe upon their employer's intellectual property rights. Depending on the terms of their contract, their work typically must be developed on their own time, using their own equipment, and be unrelated to the company’s business. It is advisable for employed participants to seek independent legal advice and/or consult with their employer regarding their submissions. The organizers shall be held harmless in the event of any disputes arising from an employed participant’s submission.

The repository must include a clear and permissive open-source license.

The prize will be paid out in the form of 25% unlocked and 75% locked DOTs with a two-year linear vesting via the on-chain vesting module.
