The ZODIAC identifier is intended to be used with a Zodiac module that allows you to control a Gnosis Safe according to a set of rules defined off-chain and enforced with UMA’s Optimistic Oracle . Unless the module contract has extra restrictions, any address can propose transactions that follow the rules and any address can dispute a proposal to UMA’s Optimistic Oracle within a challenge window.

## Summary (2-5 sentences)
The Volatility DAOracle is a collection of methodologies and implementations for indices and benchmarks. Each index can be verified by decentralized users through its data endpoint, open-source code, and methodology paper. This information can be looked up through the `requestAndProposePriceFor` call to the [SkinnyOO](https://docs-git-doc-updates-uma.vercel.app/contracts/oracle/implementation/SkinnyOptimisticOracle#parameters-4) where the following parameters can be used to query any of the indices in the Volatility DAOracle:
* `identifier`: price identifier to identify the existing request.
* `timestamp`: timestamp of the data snapshot to identify the existing request.
* `ancillaryData`: ancillary data of the price being requested.
## Motivation
In traditional finance, there are many indices and benchmarks derived from complex calculations. In the U.S. these are typically regulated through enforcement.
In light of investigations into the manipulation of benchmarks, The Board of the International Organization of Securities Commissions (IOSCO) launched a task force to generate best practices for creating and maintaining benchmarks. IOSCO complaint benchmarks are currently the gold standard. However, even with all the transparency that being IOSCO compliant adds, much of the code used in calculations is closed source. Furthermore, IOSCO compliance does not negate conflicts of interests.
