About Tagger

Tagger is a decentralised AI data infrastructure protocol that introduces a new model for collecting, verifying, and monetising AI training data. TAG is the native token that powers this ecosystem, serving as a work reward, transaction fee, and governance asset. Through smart contract automation, AI-assisted annotation, and community verification, Tagger builds a transparent and scalable foundation for AI development.
The TAG token is the native utility token of the Tagger protocol, serving operational, economic, and governance functions within the ecosystem.
  • Task Incentives: TAG is earned by data workers contributing to data collection, labelling, cleaning, and verification.
  • Access and Utility: Clients and data users spend TAG to create and manage tasks, acquire data rights, and access AI services.
  • Governance: TAG holders can vote on protocol upgrades, fee structures, and governance proposals.
  • Transaction Medium: All payments, including those for dataset rental, annotation service listings, and marketplace handling, are conducted using TAG.
  • Proof-of-Human-Work (PoHW): The issuance of TAG is based on verifiable human effort through a system that records and evaluates contributions.
Tagger was founded by Trevor Xu, an engineer with experience in decentralised systems and education technology. # Key Features and Technical Innovations
The AI annotation copilot supports data workers through intelligent labelling suggestions and real-time quality control. Using Reinforcement Learning from Human Feedback (RLHF), human validators confirm or reject AI-generated labels, creating a loop where human judgement dynamically refines model behaviour. Disagreements trigger a voting mechanism across multiple participants to reduce bias.
For edge cases and high-risk inputs, Tagger implements a multi-tiered verification architecture. Data flagged as ambiguous or inconsistent is routed to domain experts for final arbitration. This stratified design balances scalability with precision.
Each dataset and annotation file is hashed and indexed into NFT-formatted certificates. This mechanism grants ownership without compromising data privacy. Access permissions are encoded in smart contracts, enabling dataset sharing, licensing, and revocation without off-chain intermediaries.
Data collection is decentralised through a global participant base, who contribute structured and unstructured data via standardised tasks. Data is validated through cryptographic means and an automated cleansing pipeline. This system eliminates central data brokers and allows geographically distributed and real-time sourcing.

Tagger includes a permissionless marketplace supporting:

  • Sale and rental of data
  • Non-transferable authorisation licences
  • Usage audits and transparent transaction history

Every interaction is logged on-chain, ensuring accountability and traceability.
