DESCRIPTION:Decentralization has an important geographic dimension that is 
 often overlooked in protocol design. Concentration among validators and in
 formation sources can undermine security by increasing exposure to correla
 ted failures\, government bans\, and natural disasters. Yet in permissionl
 ess systems\, validator locations cannot be set by protocol rules and inst
 ead emerge from economic incentives.\n\nIn this paper\, we propose a forma
 l model of validators’ geographic location incentives under Ethereum’s
  protocol design. The model captures the interaction between local and ext
 ernal block building\, as well as the distribution of validators and infor
 mation sources. We characterize the model analytically and complement it w
 ith an agent-based simulation calibrated to real-world latency data to qua
 ntify how these incentives shape geographic concentration.
