About

Dear Builders, Mask Network brings privacy and benefits from Web3 to social media like Facebook & Twitter - with an open-sourced browser extension. Next.ID was initiated by the core team responsible for the development of Mask Network last year. Next.ID is an open-source protocol designed for developers to create and manage identities. The Next.ID protocol acts as a secure conduit connecting various web2 and web3 identifiers, such as wallets, Twitter profiles, ENS names, Lens profiles, and more. When a person's different identifiers are linked together, they form an identity graph, creating powerful, portable, and self-sovereign digital identities. We refer to these identities, digital representations of self, as Avatars at Next ID. You can check out what Avatar is at here. You can find more information on our official site: https://Next.ID Our GitHub page: https://github.com/NextDotID We are here to help you overcome any challenges: Join our Community Telegram Group for quick assistance: https://t.me/NextDotIDofficial For any questions, feel free to send an email to developer@next.id On this occasion, we have prepared a bounty of 10,000 USD for you to explore and build upon. We look forward to seeing your innovative contributions!

Dear Builders,

Mask Network brings privacy and benefits from Web3 to social media like Facebook & Twitter - with an open-sourced browser extension. Next.ID was initiated by the core team responsible for the development of Mask Network last year.

Next.ID is an open-source protocol designed for developers to create and manage identities. The Next.ID protocol acts as a secure conduit connecting various web2 and web3 identifiers, such as wallets, Twitter profiles, ENS names, Lens profiles, and more.

When a person's different identifiers are linked together, they form an identity graph, creating powerful, portable, and self-sovereign digital identities. We refer to these identities, digital representations of self, as Avatars at Next ID.

#1 Paving the Way for an Autonomous World: Creating a Secure and User-Friendly Identity Solution for On-Chain Gaming (4k USD in total)

Prize Pool

1st prize (max 1): $3k USD

2nd prize (max 1): $1k USD

Description

What is Fully On-Chain Gaming

Fully on-chain games like Dark Forest and Loot have all interactions, behaviors, and states processed via the blockchain, serving as the game's server. These games also use smart contracts for all player actions and even allow for decentralized narratives and governance through DAOs.

General Challenges We Are Facing

  • Technical Limits: Low throughput and high latency hinder real-time interactions.
  • Smart Contract Complexity: It is difficult to encode all game rules in smart contracts.
  • Hidden Info: Challenges in implementing games with hidden or incomplete information.

Specific Questions We Noticed as a DID open source protocol

Burner wallets in on-chain games like Dark Forest enhance user experience by automating transactions. However, they lack secure, intuitive key management, making them temporary solutions for storing in-game assets. This complexity limits participation to technically savvy users and hinders cross-game interoperability and reputation building in the autonomous world.

Our Thoughts to the Solution Which You May Need

In general, we propose to design a Game Account system similar to how Steam ID functions for all games within the Web2 world's platform.

A possible approach to how we design the Game Account System:

  • it can work as below, or you can design your own structure:
  • Entry Point → Game Account → Game
  • In Game Account section, it contains 3 parts:
  • AA wallet to perform as the login window
  • Proxy Logic to handle business
  • Access Control module to check if AA Wallet is properly linked with the Identity Graph
  • A Session Key handles the Entry Point
  • Frontend SDK for creating these Session Keys, binding with Avatar（the gate where the user becomes one of the dots in the Identity Graph）
  • Solidity library for on-chain game logic integration

We invite Dev with us to co-build this comprehensive identity solution for on-chain gaming, lowering entry barriers for end-users. The toolkit may include:

  • Web/Mobile SDKs
  • Optional Backend Service
  • Smart Contract Library
  • Sample Game
  • Docs

The solution consists of two parts: off-chain and on-chain.

  • Off-chain
  1. (Existing users) Use their existing wallet as their Avatar (sharing the same private key)
  2. (New users) Generate their own MPC-controlled avatar with their email
  3. For each session of each game, generate a burner per-device session key (that may or may not have an expiry time) and use Next.ID to bind with the avatar
  4. For each new session, repeat the same
  5. Each session/device key never leaves the device and could expire to protect security
  6. In-game assets and game status are synced through and built upon the avatar, which can be considered as a universal reputation
  • On-chain
  1. Generate a smart contract wallet along with identity graph(https://docs.next.id/?utm_source=nextid#what-is-an-identity-graph)
  2. Tokens can be airdropped to these wallets to pay for game plays from game creators
  3. identity graph is used to maintain on-chain social capital based on identity bindings, which can be used as factors for token airdrops or small credit loan
  4. A solidity identity library is needed to integrate into game logics to realize game asset and game status synchronization.

#2 Best Use of RelationService - Develop the Next-Gen Application with a Portable Universal Profile (6k USD in total)

Prize Pool

1st prize (max 1): $3k USD

2nd prize (max 1): $2k USD

3rd prize (max 1): $1k USD

Description

Utilize the RelationService API (https://docs.next.id/relation-service/rs-graphql) to develop a use case that addresses market needs.

Strive to be as innovative as possible.

Recommended Use Cases (but not limited to):

Cross-Platform Profile Search and Recommendations

Get an understanding of what this involves and why it's useful by visiting W**eb3.bio** first.

For instance, consider linking a Twitter account with Mastodon using a DID.

Sybil Attack Resistance by Wallet History Verification

For instance, in a significant airdrop event, bot accounts controlled by a small group of people need to be filtered out, ensuring that each user claiming the airdrop is a legitimate individual user.

DAO (Decentralized Autonomous Organizations) Tooling

For instance, a DAO member's credentials can be made portable across different blockchain ecosystems.

For instance, when a new member joins, their existing social credentials can be immediately displayed, and different access levels can be provided based on their existing profile data.

Growth and Personalization

For instance, utilize a universal profile(Similar to this one: https://web3.bio/vitalik.eth) to identify potential user personas. Track social identities using wallet addresses and use this information to create look-alike audiences.

For instance, use a universal profile(Similar to this one: https://web3.bio/vitalik.eth) to solve the cold-start problem for apps. Allow users to invite their connections on Web2 by examining the wallet addresses they interact with.

Acceptance Criteria

Proof of Work: Submit either an open-source project published on GitHub for the judges to review, or if its business value necessitates confidentiality, share a private project repo address with us.

Relevance: Your use case should be pertinent and demonstrate a practical application of the RelationService feature within the DID protocol.

Protocol Compliance: Your use case must fully adhere to the DID protocol's specifications and accurately implement the RelationService feature.

Security: Your use case must prioritize data privacy and security. It should not introduce any security vulnerabilities.

Innovation: Creative or innovative applications of the RelationService feature are highly valued, even though not strictly required.
