Running a Lightning node can certainly contribute to the robustness and decentralization of the network, even if the immediate personal benefits aren't clear. It's a bit like running a Tor relay—there's an element of public service to it. But you're correct; it's not as simple as just spinning up a node and letting it sit.
It’s essential to understand that the value you provide to the LN isn’t just in transaction routing. Node reliability, channel liquidity, and network connectivity also play significant roles.
To be a beneficial participant, here’s what you could focus on:
  1. Channel Liquidity: Providing liquidity to the network is probably the most significant contribution. You'll want to open channels with reliable nodes that have good connectivity and are frequently online. Your channel sizes should be substantial enough to be useful for routing payments.
  2. Balanced Channels: Try to maintain balanced channels. This may involve using Lightning Network tools that allow you to rebalance your channels as necessary to ensure you can facilitate transactions in both directions.
  3. Node Uptime: Keep your node online as much as possible. A reliable node is more likely to be chosen for routing payments.
  4. Fees: Setting reasonable fees is essential. If your fees are too high, others will route around you. Too low, and you might not cover your costs or you may become a channel for "griefing" attacks where your liquidity is locked up in low-value payments.
  5. Security: Regarding security issues, while connecting to random nodes can indeed be problematic, carefully choosing well-known and reputable nodes for opening channels can mitigate some risks. Also, ensure you're keeping your node software up to date with the latest security patches.
  6. Routing: By analyzing the network, you can find gaps in connectivity or areas where additional liquidity is needed and position your node to fill those gaps.
  7. Education: Continue to educate yourself on LN's best practices and the emerging tools that can help you manage your node more effectively. There are many resources available from the community that can help with this.
  8. Monitoring and Management Tools: Utilize available tools and services to monitor your node's performance and manage channels effectively. This can involve automatic rebalancing, fee adjustments based on network conditions, and more.
  9. Community Involvement: Being active in the Lightning community can provide you with up-to-date information and peer review of your node's strategy and setup.
  10. Watchtowers: Consider running or utilizing a Watchtower service, which can help protect the funds in your channels even when you're offline.
This is the answer I needed. Thank you.
