Specification for Ethereum Oracles

[gordsport]

In order to be ready for Q2 2022 development we need to agree upon the scope for the engineering team to deliver in this time period.

We require a spec for Ethereum Oracles

Related to: Notion Board

How do we know when we are done:

• The spec has been updated to indicate what are the requirements for flexible oracles and basic combinators
• The specification contains acceptance criteria with IDs that reflect the scope of the work required for Q2 2022
• The engineering team has reviewed the specifications and understand the scope
• The spec is merged into the specs repo before engineering start development/test work
