I found EchelonMC and it is a fully custom survival server on Minecraft Java. It is new with about a month of active development and it is hosted in Canada. Version 1.21.11 is recommended and older versions are supported too.
The vibe is serious building and teamwork. This is not a server for PvP stealing or griefing. It is made for people who want to build together and keep progress going long term.
A lot of the systems are custom coded and the server says it has no pay to win. They patch it a lot and they actually take player feedback to shape features and balance.
There is a path system where you can walk and make paths form under you and you can get speed bonuses on them. You can toggle it. There is also a currency called Echelites that you earn by playing and you can spend it on progression and quality of life.
Land claiming looks strong with visual borders and per chunk settings plus anti grief protection. You can control mobs and TNT and fire spread and raids and even fluids. You can also publish chunks so other players can visit your builds and you can earn rewards from visitors and climb build rankings.
It has teams with invites shared utilities and team nametags. Deaths make timed graves for your items and there is a /back to help you recover after teleports. There is voting with in game rewards plus discord linking and a chat bridge plus a spawn hub with custom NPCs and utilities and anti x ray protection.
