+# Rename Fishermen
+
+* Status: Draft
+* Deciders: Protocol Network Team
+* Date: 2023-04-25
+
+## Context and Problem Statement
+
+Fishermen is a canonically used term in [blockchain technology](https://wiki.polkadot.network/docs/learn-availability#fishermen-deprecated). In POKT Network, Fishermen are actors responsible for monitoring & reporting the behavior of Service nodes. However, the term Fishermen is ambiguous, overloaded, and doesn't describe its responsibilities in the protocol without additional context. None of other POKT actor roles have a maritime or sea based theme, further adding to the confusion. Additionally, pluralization preferences and spelling of `fishermen` is an ongoing issue in the codebase. For example, there are TODO comments about renaming `fisherman` to `fishermen`.
