What you will learn

  • Separate subsidy and transaction fees.
  • Explain why scarcity does not determine demand.

The coinbase transaction has a special role

A block’s coinbase transaction can claim the permitted subsidy and included transaction fees under consensus rules. The subsidy follows Bitcoin’s issuance schedule and decreases at defined block heights. Ordinary users cannot create the same privilege by labeling a transaction as a reward. Nodes validate the allowed amounts as part of block acceptance.

Incentives are an argument, not magic

The whitepaper discusses why miners may prefer following the rules to attacking the system. Real participants still face hardware, energy and market conditions. A rule can constrain issuance while economic behavior remains uncertain. Avoid treating a halving as a timetable for prices or assuming that a smaller subsidy alone tells the full future security story.

Keep community rewards separate

If a kitchen grant is paid in sats, those sats come from an existing approved budget. They are not newly mined because a volunteer submitted evidence. A service-review process and Bitcoin issuance operate at different layers. In educational reports, distinguish mined issuance, transfers, trading gains, donations and borrowing. Calling all incoming funds rewards can hide both the source and the obligation attached to them.

Practice on paper

A fictional block permits a 10-unit subsidy and contains 2 units in fees. A miner claims 13. What should a validating node conclude in this simplified example?

Reveal the worked answer

The claim exceeds the allowed total of 12 and is invalid. The example uses invented units to teach the accounting rule, not current Bitcoin subsidy values.

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. Do community service records create new BTC?

  • Yes
  • No
Reveal answer 1

No. Any payment must come from actual funds.

2. Does a known issuance schedule guarantee a future market price?

  • Yes
  • No
Reveal answer 2

No. Demand and other market conditions are separate.

Take this with you

Know the monetary rule and keep economic predictions distinct.
