Audit of Band Protocol’s Cosmos-SDK Oracle Module

Band Protocol has requested that Least Authority perform a security audit of the BandChain Cosmos-SDK
oracle module in the BandChain chain directory. Bandchain is a Decentralized Data Delivery Network
(D3N) built on Cosmos-SDK. BandChain aims to connect public blockchains with off-chain information
and aims to achieve the following design goals:

  • Speed and Scalability: The system must be able to serve a large quantity of data requests to
    multiple public blockchains with minimal latency and high throughput. The expected response
    time must be in the order of seconds.
  • Cross-Chain Compatibility: The system must be blockchain-agnostic and able to serve data to
    most available public blockchains. Verification of data authenticity on the target blockchains
    must be efficient and trustless.
  • Data Flexibility: The system must be generic and able to support different ways to fetch and
    aggregate data, including both permissionless, publicly available data and information guarded by
    centralized parties.
