Extension: Strategic Mining in Proof-of-Stake with Practical Random Election

Record: kaal:position:2026-08-08-370 · 2026-08-08

Strategic Mining in Proof-of-Stake with Practical Random Election identifies a concrete failure in validator selection. Distributed random beacons fix randomness across several slots because of latency. Validators can infer future election information. The study reports that, without propagation delay, a validator with any proportion of stake can profit from strategic mining and obtain higher block rewards than prior strategies. The result extends Kaal's claim that fixed consensus rules remain vulnerable to strategic gaming as conditions change. It is limited to the modeled protocol and its no-delay assumption. The evidence does not establish failure across all proof-of-stake systems.

Affirmed commentary position. This record extends a source-bound scholarly claim but is not a verbatim paper claim.
