### Prize Title
Build a Real-world Connected DApp using Band Protocol’s Built-in Oracle Scripts over Cosmos IBC
### Prize Bounty
$2000 in BAND
- $1000 each to two winners
### Challenge Description
Band Protocol allows developers to create a custom data oracle script to define their data sources and aggregation method to suit their respective needs. This enables decentralized applications to tap into high-quality data sources and aggregate data points into a single deterministic value without sacrificing security and decentralization.
The challenge is to create a decentralized application connected to the real-world using one or more of the following built-in oracle scripts on BandChain:
- Random Number Generator
- Flight Verification
- Weather Info
- Ethereum Gas Cost
- Bitcoin Block Hash
If you wish to access data from other external APIs, please reach out to the Band Protocol team who will assist you in building a custom oracle script to suit your use-case.
Leverage the flexibility and customizability of BandChain to create a dApp or protocol that is connected to the real-world. Here are some suggestions:
- Prediction markets
- Games or gambling
- Cross-chain token swaps
- Automated trading sets
### Submission Requirements
- Request and consume oracle data from BandChain over Cosmos IBC
- Be open-source
- Have a working demo (strongly recommended) or an exceptional proof-of-concept which can be in the form of wireframes, landing page, prototypes or production code.
### Submission Deadline
May 11th, 23:59:59 UTC
### Judging Criteria
The prize will be awarded to the submission that produces the:
- Best implementation of IBC & Band Protocol’s oracle flexibility
- Most innovative approach to solving the strongest paint points
- Highest degree of originality from existing dApps
### Winner Announcement Date
May 18th, 2020
