Opendata price feed Oracle ($2,500) #5

Closed kesar closed 3 years ago

kesar commented 3 years ago

Description

Develop an EOS smart-contract that allow to verify signatures from open data oracles. Allow set bounties per data push. Store median of last prices.

Contract should have an action where anyone can push a json string that comes from the coinbase / okex API. Contract must parse that json and validate the signatures, then store pair information in a table and calculate aggregated data (median, etc).

Entities will have an easy & documented eos table that can integrate in their products for pricing oracles. Those entities should be able to fill a bounty table transfering IQ tokens.

There must be a configurable table to set the bounty per data push, and oracles that push the data will earn a fee per push. Contract should only allow one unique push of data, so nobody can send twice same data.

Contracts must have a test suite build with boost similar to eosio.contracts. Please you must use this project as template ( https://github.com/kesar/eos-dev-template ) that uses docker + makefiles + boost unit tests.
