Half of the credibility of PoB comes from what it admits, and half comes from what it firmly does not record in the ledger.
The scarcity of PoB comes from a double gate: admitting high-standard results and systematically rejecting inputs that are easy to forge, repeat, and outsource. Without exclusion rules, the network would repeat the distortion that Web3 has already seen - optimizing snapshot rules instead of optimizing delivery.
Explicitly exclude: Behavior that has not yet entered the results layer
Pure posting, pure forwarding, pure group building, pure recommendation without follow-up, pure intention negotiation, and "help" without deliverables do not constitute PoB objects. The reason has nothing to do with PoW/PoS: the marginal copying cost of these behaviors approaches zero, and there is no stable causal chain with the business end state - if it is accounted for, incentives will flow to volume and relationship performance rather than output.
Pseudo-contribution and anti-gamification points
Why it's different from common Web3 rewards
- Airdrops and Tasks: Optimize Rule Programmability, but not optimize Delivery Quality; Witch cost can be lower than the real customer acquisition cost.
- Pledge: Optimize Capital Lock, do not optimize Service Completion; large accounts may not complete any customer closed loop.
- Points Ranking: Optimize short-term action frequency to easily decouple from real alpha in the Brinson sense.
PoB deliberately increases the cost of "scoring", so that it is better to make a real closed-loop transaction than to earn points. This is the economic core of anti-gamification, not just a moral appeal.
If "what doesn't count" is laxly implemented, PoB will quickly be diluted into another marketing score; strong implementation relies on Proof Desk standards, transparent records of supplements and rejections (see 8.4).
The exclusion rules protect the scarcity of results and the marginal returns of honest nodes; what they harm is the settlement semantics of the entire network.
