Accounts

• GuardianSignatures stores unverified guardian signatures for subsequent verification. These are created with post_signatures in service of verifying a root via Queries and closed when that root is verified with verify_query or can be explicitly closed with close_signatures by the initial payer.
• State stores config variables relevant to receiving and verifying a staking pool rate and making it available for consumption.

Instructions

• post_signatures posts unverified guardian signatures for verification during update_root_with_query.
• verify_query with a Query response and GuardianSignatures account, verifies the signatures against an active guardian set and logs the Query response. This is where you would add additional verification relevant to your use case and process the result.
• close_signatures allows the initial payer to close a GuardianSignatures account in case the query was invalid.
• update_pool takes the cross chain query response for the stake pool on Ethereum and stores the result.
• get_rate reads the current total_active_stake from State if not stale.
