I found three of the best nodes to set up in 2025 (with rewards):

1. Aztec / @aztecnetwork (~$20/month):

Aztec Network is a private ZK-rollup on Ethereum. Since 2018, they have raised around $120M from top VCs and Vitalik Buterin. Recently, they launched the opportunity to set up nodes.

Hardware Requirements:

> CPU: 8 cores

> RAM: 16 GB

> Storage: 1 TB

2. Gaia / @Gaianet_AI (~$25/month):

This is an interactive node representing an AI agent. You can't just "set it and forget it" to earn points. You need to write messages and train your LLM agent. Gaia has raised $10M and confirmed rewards.

Hardware Requirements:

> CPU: 8 cores

> RAM: 16 GB

> Storage: 120 GB

3. Grass / @grass (~$0/month):

Grass is widely known, and I had to include it on this list. There are still many tokens available for future rewards, with significantly fewer users. Extensions have recently been disabled, leaving only desktop apps, so it can be considered a full-fledged node now.
