The contracts repo serves as a curation market platform targeted at on-chain/off-chain data-providers. It allows data-providers to serve data to a variety of endpoints and to monetize data via provider-specific bonding markets in which data-consumers and/or speculators stake token amounts to data-provider accounts in exchange for data-provider-specific access tokens, ‘dots’, which are redeemable as:

  • query requests to the data-provider in request endpoints( ex. smart contract endpoint)

  • subscription periods to data-provider streams in subscription endpoints (ex. ipfs pubsub socket endpoint) or

  • an amount of token determined by data-provider-specific bond market price
