Tournament results: Verifiable outcomes
Identity & Attestations
Claims about identity:
KYC attestations: Verified once, prove forever
Membership proofs: DAO participation
Skill verification: Endorsed credentials
Reputation scores: Accumulated history
IoT & Sensors
Device data logging:
Sensor readings: Tamper-proof data
