Nova Labs’ Denylist project, developed at the behest of the Helium community through an on-chain vote, serves as a critical mechanism in maintaining the integrity of the Proof-of-Coverage system by excluding compromised Hotspots. The Denylist is a pivotal component utilized in Helium’s firmware to prevent Hotspots on the list from generating challenges or being detected via witness receipts, thus preserving network consensus. While manufacturers have the option to adopt this listing, the methodology for generating it may remain undisclosed to safeguard against potential misuse. Updates and modifications to the Denylist are managed through open contributions and independent validation processes via Crowdspot.io. An established multisig process involving community contributors ensures the authenticity and integrity of list updates, secured through a systematic signing procedure with the xorf-generator and helium-wallet tools, guaranteeing robust network functionality and security.
