There are three primary approaches to resolving this problem:
- Use a trusted data source, a centralized solution
- Use the median from a set of data feeds, also a centralized solution
- Use a Schelling point scheme, a decentralized solution
The best understood solution to the oracle problem that also provides a decentralized data feed uses a mechanism that relies on Schelling points.
Schelling points, named after theorist Thomas Schelling who introduced them ...
