b7s (Blockless Networking Daemon)

b7s is a peer-to-peer networking daemon for the Blockless Network, designed to facilitate distributed computing and resource management. It supports Windows, Linux, and MacOS platforms on both x64 and arm64 architectures.

You can find the repository on GitHub (opens in a new tab).


You can install b7s using either curl, wget, or Docker:

Using curl

sudo sh -c "curl | bash"

Using wget

sudo sh -c "wget -v -O; chmod +x; ./; rm -rf"

Using Docker

You can also use Docker to install b7s.


  • A machine running Docker
  • A valid AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY for an S3-compatible storage provider. This is used for backing up your node's keys and configuration.
  • A valid KEY_PATH and KEY_PASSWORD for your S3-compatible storage provider. This is used for backing up your node's keys and configuration.

Running the Image

First, pull the latest version of the b7s Docker image from the public registry:

docker pull

Then, run the image:

docker run -d --name b7s \
  -p 9527:9527 \
