RedStone / redstone-oracle

RedStone is a blockchain Oracle protocol, which proposes a completely new modular design, where data is first put into a data availability layer and then fetched on-chain. This allows us to broadcast a large number of assets at high frequency to a cheaper layer and put it on chain only when required by the protocol.

The @redstone-finance/fuel-connector module implements an alternative design of providing oracle data to smart contracts. Instead of constantly persisting data on the Fuel network storage (by data providers), the information is brought on-chain only when needed (by end users). Until that moment data remains in the DDL (decetrnalized data layer), which is powered by RedStone light data gateways and streamr data broadcasting protocol. Data is transferred to the Fuel network by end users. The information integrity is verified on-chain through signature checking.

Basic POC Test

• For the library https://github.com/redstone-finance/redstone-fuel-sdk/:

  • https://github.com/redstone-finance/redstone-fuel-sdk/blob/main/README.md

• For the contracts:

  • https://github.com/redstone-finance/redstone-oracles-monorepo/blob/main/packages/fuel-connector/sway/README.md

Out of scope

Inside *.sw files:

• do not audit doc/comment messages
• do not audit functions marked as #[test]/#[test(should_revert)] and functions below any #[test]/#[test(should_revert)] in the file (these are helper test functions)
• do not audit lines like:
  • use* (with all contained dependencies),
    • const*/pub const*,
    • empty line,
    • single line containing only reserved sway words (like library, where)
    • do not audit files like lib.sw,
    • other library headers (like: src/core.sw /src/crypto.sw /src/lib.sw /src/protocol /src/utils.sw)
