Feature: proof-of-funds via multiple sources (aggregate balances across linked accounts)

[Psalmuel01]

funds proofs use a single balance source. Real proof-of-funds often spans multiple accounts. Support aggregating balances before the threshold check.

Scope

• Let the issuer attest to a summed balance across multiple linked accounts (e.g. several Plaid items), signing the aggregate commitment.
• The circuit still proves aggregate >= threshold without revealing components.
• Keep identity/source data server-side and out of storage.

Value

Matches how proof-of-funds actually works, widening real-world applicability.

Acceptance

• An aggregate balance across sources can be attested and proven against a threshold; components stay private; documented.

Hi Maintainer, I’d be interested in taking this issue on and extending the proof-of-funds flow to support aggregated balances across linked sources. I can keep the individual account details private while preserving the existing threshold-proof model. Please assign it to me.
