Greenlight
Greenlight by Blockstream: Lightning Made Easy. It provides simple, secure access to the Lightning Network, allowing anyone to spin up their Lightning node in the cloud while retaining complete control over their funds. Greenlight allows anyone to boot up their personal Lightning node on our cloud infrastructure in seconds and take full control over their funds. The private keys, required to sign both on-chain and off-chain transactions, never leave the user’s device. Users interact with the node via a simple programmable interface and we take care of the rest. We schedule the node on our infrastructure when needed, managing everything from the Bitcoin back-end to encrypted backups and watchtowers. You take care of your funds, we’ll manage the rest. When scheduled to run on the infrastructure, the node will attempt to connect to the user’s device which holds the keys and ask for sign-off on any operation that involves the user’s funds. When the user isn’t using their node, it shuts down automatically until it’s needed again. Starting the node is almost instantaneous, ensuring that the user experience is seamless.
