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.
