DataHive

DataHive is a data marketplace for AI training that breaks collection, cleaning and labelling into priced tasks. A requester opens a campaign with data type, quality bar and unit price, contributors submit text, images, audio or video, and payment settles instantly in the platform token; submissions are first checked by a multi-agent review flow that dynamically picks among vision and language models to judge authenticity and compliance.

Data lands in decentralised storage, with a dedicated bucket provisioned per dataset at campaign creation and locked behind an RSA key pair, the public key stored on-chain and the private key held by the requester, so only that key can unlock the dataset or start training. Contributor history accumulates through on-chain badges and quality scores into portable reputation, and strong records unlock higher-priced tasks.
