PoB must not only answer "what happened", but also "who promoted it and how" with the participation of multiple parties.
PoB can prove the existence of results, but if attribution is unclear, settlement will still degenerate into political distribution. The task of the attribution layer is to establish a defensible contribution mapping within the same closed loop - who removes key blockers, who provides input with low substitutability, and who only participates in the periphery - similar to splitting the total return into explainable parts in portfolio management.
basic principles
Without attribution, PoB only proves the results; with attribution, PoB can support the harder question of who creates distributable value.
Mental alignment with Brinson/GIPS (not verbatim equivalent)
- Brinson: Total excess returns are split into asset allocation, security selection, and interaction effects. WCN: Total closed loop is divided into resource introduction, execution promotion, risk removal, final state sign-off and other narrative blocks, and then bound to nodes or agents.
- GIPS: Performance presentation must be fair, complete, and consistent. WCN: Attribution conclusions should be consistent with the evidence package and timeline, and "all-dominant" narratives supporting the conflict using the same material are prohibited.
The "rewards in proportion to stake" of PoS on the chain are capital weight; PoB attribution is contribution structure - the two can be combined, but cannot replace each other.
Role differentiation (semantic layer)
Practical Tip: Reduce the hassle
- Write it out as early as possible: Deal/Task layer agrees on the expected attribution framework (can still be modified by PoB, but reduces subsequent disputes).
- Timeline Priority: Email, calendar, contract effective date, and on-chain transaction timestamps are cross-aligned.
- Objection Procedure: You can apply for review of the archived conclusion, but you need to attach new materials or point out specific logical errors to prevent endless delays.
The quality of attribution determines whether nodes are willing to do heavy work, a long cycle, and a closed loop that is difficult to prove. If it is always "whoever shows up last gets the prize", the network will become short-sighted, which is contrary to the long-termism of PoB.
