Calling developers to create a groundbreaking solution that ensures artists receive their royalties from every sale, regardless of the marketplace.

Your solution should seamlessly integrate with the TON blockchain ecosystem while aligning with the existing NFT standard. While a reference implementation is optional, we're eager to see your technical prowess and visionary ideas.

Prizes and submission
We value your dedication and expertise. The contest winner will walk away with an enticing cash prize of $2,000 paid on TON! But that's not all — every participant will gain industry recognition, professional exposure, and a platform for future collaborations and partnerships.
The bot for submitting the solutions will be opened prior to the deadline.

Evaluation Criteria
Our expert judges will assess each submission based on the following criteria:

1️⃣ Compatibility: How well your solution integrates with the existing NFT standard, while introducing innovative features.

2️⃣ Technical Excellence: The sophistication and practicality of your solution in a real-world context.

3️⃣ Scalability and TON Compatibility: Your solution's ability to scale and adapt within the TON blockchain ecosystem.

4️⃣ Documentation Quality: The clarity, comprehensiveness, and user-friendliness of your documentation and implementation guidelines.

Come join us in revolutionizing the TON NFT ecosystem and supporting artists!

W5 Optimization Challenge

Prize: up to 2,000 TON
Deadline: October 15, 23:59 UTC+4
Results: November 11

The Tonkeeper team is working on a new wallet standard called W5 aimed at replacing the currently used wallet v4R2. It will enable new exciting possibilities for TON that dramatically improve user experience for millions of people.

W5 supports gasless transactions, delegation and account recovery, subscription payments with tokens and Toncoin, and cheap multi-transfers. At the same time, W5 significantly reduces user and merchant fees.

Learn about W5 from our GitHub repository.

We invite talented Fift and FunC engineers to participate in optimizing W5. The most optimized solution that meets the requirements will win the contest.

Requirements
The goal is to optimize gas consumption for each of the three computation paths, where a single outgoing message of 1 TON to a regular basechain address is emitted from the wallet:

1. Processing an external signed message. Starting gas cost: 3135.
2. Processing an internal signed message. Starting gas cost: 4110.
3. Processing an internal message authenticated by an extension. The dictionary contains only that one extension. Starting gas cost: 2660.

The starting gas costs are measured when the entire contract code is offloaded to a library on a masterchain. Measurements were made on testnet.

Non-goals: optimizing the storage space, optimizing the code size (the code will be offloaded into a shared library and won’t cost anything to a user).

While optimizing these three cases, do not impede the remaining functionality. Minor trade-offs are acceptable, but a significant increase in cost, usage complexity, or loss of security may disqualify a candidate.

The resulting code in FunC or Fift must contain excellent documentation necessary for audit and a documented build process if it differs from the one we already use in the repository.

Implementation should be generally compatible with the ABI in the specification.

Minor changes to the storage and message layout are allowed for the performance if they do not break the functionality and do not complicate the ABI for apps. Please do not change the 32-bit opcodes. We reserve the right to decide which changes are acceptable. When in doubt, feel free to make two submissions: conservative & radical..

Deliverable
Pull-request to w5 repository.

Prizes
🥇The author of the winning implementation receives co-authorship credit in the project and 0.333 TON per gas unit saved in each of the three paths (external+signed, internal+signed, internal+extension).

We also reward original ideas with novel trade-offs and worthy follow-up attempts.

🥈The second place: 0.100 TON per gas unit.
🥉The third place: 0.050 TON per gas unit.

We will pay out only one prize per author. We will evaluate submissions one by one. To avoid copycats, we recommend you submit your code shortly before midnight on October 15 (UTC +4).

We can’t wait to see how your talents unfold in this challenge. Good luck!

TonTech NFT Royalty standard contest

Hey everyone! We're excited to reveal the results of the NFT Royalty Standard contest. We received four submissions, but unfortunately, none of them met our expectations in terms of proposal quality. Here's a detailed review of each project:



1. hitaspdotnet's solution:

    - The solution lacks a guarantee on the size of royalties paid.
    - Its architecture opens up possibilities for scam use cases.
    - Involves too many transactions (4) for a single transfer.
    - Does not align with the current NFT standard and violates the transfer operation.
    - Allows the NFT to be put on sale to multiple contracts due to the ability for multiple users to transfer it.

2. Roman22022000's submission:

    - Unfortunately, we were unable to comprehend the ideas presented by Roman.

3. Ton-Dynasty's solution:

    - Considered overcomplicated and lacking practicality in terms of royalty enforcement.

4. coalus's implementation:

    - Although the idea is interesting, the problem remains unsolved as normal transfers still exist in this implementation.



In our internal research at TonTech, we've explored potential solutions and believe that a public whitelist of code hashes could be effective in ensuring the safe transfer of NFTs. 

This whitelist, which can be stored on-chain as Merkle proofs in the global config for decentralized control, contains contracts which are proven to be safe to transfer NFT to, like wallets, NFT sale contracts, etc.

This could be achieved by adding the state initialization of the new_owner contract to the transfer message with a proof verifying that the contract code is indeed on the whitelist. This approach allows the NFT to:

- Check the code against a whitelist.
- Verify that the state initialization leads to the correct new_owner address.

However, it's crucial to acknowledge a major drawback: we cannot guarantee the security of the solution if the new_owner contract is an updatable contract. This is particularly problematic since the contract code could be updated to become something else. Given that the wallet w5 contract is likely to be updatable, this solution poses inherent challenges.

Despite not finding a satisfactory solution in the contest, we would like to express our gratitude to all participants for their time and effort. Recognizing their contributions, we have decided to reward each participant with 200 TON for their commitment and dedication. We understand that the contest may not have yielded the desired outcomes, but we value the creativity and tenacity shown by the participants.

Let's continue exploring innovative solutions to address these complexities and enhance the security and reliability of NFT royalty enforcement.
