Release v0.1.0 — package tlw-node-installer-0.1.0.tar.gz, with SHA256SUMS covering the package and the bridge binary.

Verify the checksum (SHA-256)

The file tlw-node-installer-0.1.0.tar.gz must have this hash:

SHA256(tlw-node-installer-0.1.0.tar.gz) = 3040a213d2e16afc5ec2bb78e3f998cd7b8adb8816be86edb77f8d4c731130f6

Verify on Linux

sha256sum tlw-node-installer-0.1.0.tar.gz

Verify on Windows (PowerShell)

Get-FileHash .\tlw-node-installer-0.1.0.tar.gz -Algorithm SHA256

Install (3 commands)

tar -xzf tlw-node-installer-0.1.0.tar.gz
cd tlw-node-installer-0.1.0
./install.sh --bitcoind-rpc rpcuser:[email protected]:8332

Run it as your regular user: sudo is never required.

At the end the installer prints an NWC/NCC URI: paste it in the app (Lightning → Connect) to control the node. The URI contains a secret — never share it: each device is individually authorized and can be revoked.

Requirements

Ubuntu 22.04 / 24.04 / 26.04 (x86_64)
A reachable bitcoind blake2b via RPC (the full node is not included)
curl and python3 (standard on Ubuntu)

What the installer does

installs Core Lightning (blake2b fork) and the NWC/NCC bridge, each with a pinned SHA-256: any mismatch stops the installation (fail-closed);
creates a dedicated rune on the node and an authorization URI per device;
everything is user-level (~/cln-blake2b, ~/bridge, ~/.lightning): no system changes, no root;
--uninstall removes binaries and configuration but never touches the wallet datadir (funds, channels, keys stay).

Security & trust

self-hosted by design: the node runs on your server; nobody else can operate it;
the bridge accepts requests only from devices you authorized;
