Welcome to try the BTFS 2.0 testnet


What is BTFS?

BitTorrent File System (BTFS) is a protocol forked from IPFS that utilizes the TRON network and the BitTorrent Ecosystem for integration with DApps and smart contracts.

The download and install instructions for BTFS are over at:

System Requirements

BTFS can run on most Linux, macOS, and Windows systems. We recommend running it on a machine with at least 2 GB of RAM (it’ll do fine with only one CPU core), but it should run fine with as little as 1 GB of RAM. On systems with less memory, it may not be completely stable. Only support compiling from source for mac and unix-based system.

Install Pre-Built Packages

We host pre-built binaries at

Initialize a BTFS Daemon

$ btfs init
initializing BTFS node at /home/ubuntu/.btfs
generating 2048-bit keypair...done
peer identity: 16Uiu2HAmHmW9mHcE9c5UfUomy8caBuEgJVP99MDb4wFtzF8URgzE
to get started, enter:

        btfs cat /btfs/QmPbWqakofrBdDSm4mLUS5RE5QiPQi8JbnK73LgWwQNdbi/readme

Start the Daemon

Start the BTFS Daemon

$ btfs daemon

Build from Source


Clone the go-btfs repository

$ git clone

Navigate to the go-btfs directory and run make install.

$ cd go-btfs
$ make install

A successful make install outputs something like:

$ make install
go: downloading v0.2.28
go: extracting v0.2.28
go: finding v0.2.28
go version go1.14.1 darwin/amd64
bin/check_go_version 1.14
go install  "-asmflags=all='-trimpath='" "-gcflags=all='-trimpath='" -ldflags="-X "".CurrentCommit=e4848946d" ./cmd/btfs

Afterwards, run btfs init and btfs daemon to initialize and start the daemon.

Linux VM

Developers wishing to run a BTFS daemon on a Linux VM should first set up the environment. On an AWS EC2 Linux machine for example, it would be helpful to first install the following tools and dependencies:

$ sudo yum update          // Installs general updates for Linux
$ sudo yum install git     // Lets you git clone the go-btfs repository
$ sudo yum install patch   // Required for building from source
$ sudo yum install gcc     // Required for building from source

Building BTFS from source requires Go 1.14 or higher. To install from the terminal:

$ cd /tmp
$ GO_PACKAGE=go1.14.linux-amd64.tar.gz
$ sudo tar -xvf $GO_PACKAGE
$ sudo mv go /usr/local
$ sudo rm $GO_PACKAGE

Navigate back to root directory and set the Go Path in the environment variables:

$ export GOPATH=${HOME}/go
$ export PATH=$PATH:/usr/local/go/bin
$ export PATH=$PATH:$GOPATH/bin
$ export GO111MODULE=on

Verify the Go version is 1.14 or higher:

$ go version

Navigate to the go-btfs directory and run make install.

$ cd go-btfs
$ make install

Afterwards, run btfs init and btfs daemon to initialize and start the daemon. To re-initialize a new pair of keys, you can shut down the daemon first via btfs shutdown. Then run rm -r .btfs and btfs init again.


Developers also have the option to build a BTFS daemon within a Docker container. After cloning the go-btfs repository, navigate into the go-btfs directory. This is where the Dockerfile is located. Build the docker image:

$ cd go-btfs
$ docker image build -t btfs_docker .   // Builds the docker image and tags "btfs_docker" as the name 

A successful build should have an output like:

Sending build context to Docker daemon  2.789MB
Step 1/37 : FROM golang:1.15
 ---> 4fe257ac564c
 ---> Using cache
 ---> 02409001f528


Step 37/37 : CMD ["daemon", "--migrate=true"]
 ---> Running in 3660f91dce94
Removing intermediate container 3660f91dce94
 ---> b4e1523cf264
Successfully built b4e1523cf264
Successfully tagged btfs_docker:latest

Start the container based on the new image. Starting the container also initializes and starts the BTFS daemon.

$ docker container run --publish 8080:5001 --detach --name btfs1 btfs_docker

The CLI flags are as such:

  • --publish asks Docker to forward traffic incoming on the host’s port 8080, to the container’s port 5001.
  • --detach asks Docker to run this container in the background.
  • --name specifies a name with which you can refer to your container in subsequent commands, in this case btfs1.

Configure cross-origin(CORS) You need to configure cross-origin (CORS) to access the container from the host.

(host) docker exec -it btfs1 /bin/sh // Enter the container's shell

Then configure cross-origin(CORS) with btfs

(container) btfs config --json API.HTTPHeaders.Access-Control-Allow-Origin '["http://$IP:$PORT"]'
(container) btfs config --json API.HTTPHeaders.Access-Control-Allow-Methods '["PUT", "GET", "POST"]'


(container) btfs config --json API.HTTPHeaders.Access-Control-Allow-Origin '["http://localhost:8080"]'
(container) btfs config --json API.HTTPHeaders.Access-Control-Allow-Methods '["PUT", "GET", "POST"]'

Exit the container and restart the container

(container) exit
(host) docker restart btfs1

You can access the container from the host with http://localhost:8080/hostui .

Execute commands within the docker container:

docker exec CONTAINER btfs add --chunker=reed-solomon FILE

Getting Started

Some things to try

Basic proof of 'btfs working' locally:

echo "hello world" > hello
btfs add --chunker=reed-solomon hello
# This should output a hash string that looks something like:
# QmaN4MmXMduZe7Y7XoMKFPuDFunvEZU6DWtBPg3L8kkAuS
btfs cat <that hash>

  located at ~/.btfs. To change the repo location, set the $BTFS_PATH
  environment variable:

    export BTFS_PATH=/path/to/btfsrepo


Some places to get you started on the codebase:

Development Dependencies

If you make changes to the protocol buffers, you will need to install the protoc compiler.

BTFS Gateway

BTFS Gateway is a free service that allows you to retrieve files from the BTFS network in your browser directly.
