Attestation Ideas Across All Tracks

Attestations are digital signatures on structured data used to build more trust on-chain. BNB Attestation Service (BAS) is an infrastructure built on the BNB ecosystem for generating attestation to verify information. BAS assists users in on-chain or off-chain verification, allowing them to assert ownership of attestation by storing them in Greenfield. This approach ensures data privacy and access control.

Let’s explore how you can apply these in each track:

Gaming

By tailoring its infrastructure to the demands of gaming logic and economics, BNB Chain is supporting the current wave of blockchain gaming and shaping its future, demonstrating a commitment to leading this dynamic sector.

Attestation Ideas

• Proof-of-Personhood: Develop a tool that allows individuals to make cryptographic attestations proving they are unique human beings, using biometric information while ensuring their privacy. 
• Game Achievements: Verify and confirm new in-game achievements and unlocks earned by the user.
• In-Game Item Ownership: Ensure the security of in-game item ownership by verifying and attesting to the rightful owner and all item transfers.
• Leaderboard: Attest to various achievements a player achieves and showcase them in a leaderboard.

Social

Innovate on the social network with blockchain technology

The decentralized social network should be a crypto native platform that supports various social features such as social graph, messaging, live streaming, and content sharing.

Attestation Ideas

• Social Graphs: Using BAS as the base layer for social graphs enables the creation of truly decentralized and interoperable social networks. Attestations provide a way for users to securely and selectively share their data with others, while retaining control over their personal information.
• KYC: Build a base layer for attestations would allow different organizations and services to provide attestations about different aspects of a person's life, such as education, work history, and other credentials
• Reputation System: With BAS, attestations about trust scores and relative experiences can be recorded on BNBChain or off-chain in Greenfield, providing a secure and tamper-proof record of reputation.

Payments

Build a consumer payment experience with seamless and efficient payment options for users and foster broader adoption and utility within the ecosystem

BNBChain also provides a comprehensive solution to build a dedicated payment Layer 2 (L2), further optimizing user experiences. Moreover, stablecoins on BNBChain are enthusiastic about collaborating closely with these payment platforms.

Attestation Ideas

• Transaction Receipts: Provide immutable transaction receipts that offer additional context, allowing both parties to verify them independently. 
• Verified Merchant Accreditation: Enhance buyer confidence by verifying a merchant's accreditation, transaction history, or customer satisfaction ratings.
• Refund & Return Authenticity: Create a system where refunds and returns are attested, ensuring all parties acknowledge and agree on the order status.
• Onchain Invoice Verification: Verify an invoice and confirm timely payments to establish the creditworthiness of specific addresses.
