The Lightning Network promised us Bitcoin transactions with instant, low-cost payments and to an extent, it has delivered, but not without a trade-off involved.
If you want those quick and cheap transactions, you’re forced to your own Lightning node, which traditionally requires technical expertise and dedicated hardware.
That’s if you’re going to run it the non-custodial way.
So you’re telling me to save on transactions. I first need to commit capital to buy a home server and a hard drive, spend a weekend setting it up, then lock in some Bitcoin to create a channel, and then avoid on-chain fees.
So I’m down $800 bucks to save $30 on transactions, potentially?
It’s a big ask for many.
The cost and complexity of setup is why many Lightning users aren’t using Lightning non-custodial; they’re either using an exchange or a custodial wallet, such as Blink, Wallet of Satoshi, or CoinOs.
Cloud-based Lightning node solutions have added another option to the conversation, making it possible for anyone to operate a node while maintaining full custody of their funds through mobile wallets.
Why Choose Cloud Lightning Nodes?
Before diving into specific solutions, let’s look at the benefits of cloud-hosted Lightning nodes:
- Always Online: Unlike home nodes that may go offline, cloud nodes maintain 24/7 connectivity, ensuring your channels remain active and you can receive payments anytime.
- No Hardware Requirements: Eliminate the need for dedicated hardware, reducing upfront costs and maintenance overhead.
- Professional Infrastructure: Benefit from enterprise-grade servers, redundancy, and network connectivity without managing the technical details yourself.
- Mobile-First Experience: Access your Lightning node from anywhere using your smartphone, making Bitcoin payments as easy as using any mobile app.
- Maintained Custody: Unlike custodial wallets, you retain control of your private keys and funds while enjoying the convenience of cloud infrastructure.
Option 1: Blockstream Greenlight with Blockstream Green Wallet
What is Greenlight?
Blockstream Greenlight provides users with a Lightning node within an existing Bitcoin wallet.

The Future of Cloud Lightning Nodes
Cloud Lightning nodes aren’t a total package solution to bring Lightning to the masses. While they do their best to reduce the technical barriers while maintaining self-custody, these services make Lightning Network participation accessible to a broader audience; there’s still a larger audience who will find it difficult to stomach and prefer the safety of a custodian.
Cloud LN nodes may onboard a larger cohort than the strict DIY node implementation of Lightning, providing app developers with a broader user base to work with and encouraging them to build sleeker user interfaces with more options for users.
In the future, we could see mobile wallets adopt a sort of multi-cloud approach, where you can sync with multiple cloud node operators or LSPs, custodial services, and even your own node, and switch between them as needed.
Providing the novice user with a playground to start at level 1 and migrate to higher levels as they become more comfortable with Lightning.
Cloud nodes are still someone else’s computer
Cloud Lightning nodes offer a new entry point into the Lightning Network, providing the benefits of running your own node without the technical complexity.
But they are still someone else’s computer. If those servers go down, you’re out of luck, and you’re placing your trust in another person’s tech stack.
Going to the cloud is not risk-free.
Whether you choose Greenlight’s simplicity, Alby Hub’s comprehensive features, or Voltage’s professional infrastructure, you’ll be participating in Bitcoin’s payment layer while maintaining control of your funds.
The key is to start with the solution that best matches your current needs and comfort level. As you become more familiar with Lightning Network operations, you can always migrate to more advanced solutions or even transition to self-hosted nodes if desired.
Remember that running a Lightning node, even in the cloud, involves active participation in the Bitcoin network. Take time to understand the basics of channel management, liquidity, and Lightning Network operations to make the most of your chosen solution.
Learn how to open and close channels and sweep funds back on-chain if you’re familiar with the process from start to finish. While also inquiring about how to recover funds should a node go down, or how to issue a justice transaction should a channel partner attempt to rug you.
Oh, and never commit more capital than you’re willing to lose.
