What you will learn
- Distinguish received, restricted and spent funds.
- Recognize the limits of a public address balance.
Start with a real recipient and purpose
A donation page should identify the accountable beneficiary, intended use and verified receiving method. A community story is not evidence of control over an address. Nor does an address copied from an unrelated wallet establish a valid receiving setup. The sender needs enough information to understand whom they support and what the project actually promises.
Receipt is not impact
A transaction can support a claim that funds arrived. It does not prove that ingredients were bought or meals served. A useful report connects receipts, approved expenses and outcomes while keeping sensitive details private. Restricted donations need separate treatment from general operating support. A large public address balance can include unrelated funds, change outputs or obligations that the viewer cannot see.
Publish what helps people check
For a fictional meal pilot, show the approved budget, aggregate receipts, spending categories, remaining restricted balance and corrections. Do not expose guests’ identities to create an impression of transparency. Donation recognition should be optional. Avoid promising a tax deduction, refund entitlement or legal status without the relevant established basis. Human stewards control spending; an agent may help reconcile redacted records but cannot convert a donor’s intent into a new mandate.
Practice on paper
A program receives 100,000 sats restricted to ingredients and spends 60,000 on approved ingredients. A designer asks to use the remaining amount. What should the report and steward say?
Reveal the worked answer
The report shows 40,000 sats remaining for the restricted purpose, before any separately recorded fees. The steward cannot silently redirect it; the purpose and applicable agreement govern what happens next.
Check your understanding
Choose an answer in your head or on paper, then reveal the explanation. Retry whenever you like. Answers are not submitted or scored; completion marks are your own learning notes.
1. Does an address balance prove meals were delivered?
- Yes
- No
Reveal answer 1
No. Financial and service evidence are separate.
2. Should a guest disclose a wallet to receive food?
- Yes
- No
Reveal answer 2
No. Access to a free meal must not depend on financial surveillance.
Take this with you
Make the purpose and accounts checkable without turning service into surveillance.
