The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

the extra reward of T-PAW compared to PAW improves by an unbounded factor as adversarial hash fraction α, pool size β and adversarial network influence γ decreases. For example, the extra reward of T-PAW is 22 times that of PAW when an adversary targets a pool with (α,β,γ)=(0.05,0.05,0).

C2weakest assumption

The modeling assumes rational miners optimize over a specific reward function with parameters α, β, γ and a fixed T, without accounting for real-world detection, retaliation, or pool countermeasures that could eliminate the advantage.

C3one line summary

T-PAW generalizes PAW by limiting withholding to at most T time units, producing unboundedly higher extra rewards than PAW as adversary hash fraction, pool size, and network influence decrease, while making honest mining sub-optimal with non-trivial gains.
