Non-Signature Servside Validations & Derivations

[apbendi]

Implement data validations & derivations server side as appropriate for endpoint submissions, excluding attestation signatures.

Validations

• Validation of all required fields on create
• Validating correctly formed Ethereum accounts
• Validating end date is in the future
• Validating at least two poll options are provided
• Validating existence of event ids
• Validating ownership of voting token ids
• Validate all token qualifying tokens are voting
• Validating the qualification of voting tokens to vote in this poll
• Validate no tokens have already voted in this poll
• Validate this account has not already voted in this poll
• Validating the poll option belongs to the poll being voted on
• Validating Database read/writes & returning error on failure
• Validating no poll with the identical attestation currently exists (to mitigate replay)

Derivations

• Deriving the start date + date cast from "now"
• Deriving the fancy id from the title + existing conflicts
