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 API documentation walks developers through BTFS setup, usage, and API references.
- Please join the BTFS community at https://discord.gg/PQWfzWS.
The download and install instructions for BTFS are over at: https://docs.btfs.io/docs/btfs-demo.
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.
We host pre-built binaries at https://github.com/TRON-US/btfs-binary-releases.
$ btfs init

to get started, enter:
btfs cat /btfs/QmPbWqakofrBdDSm4mLUS5RE5QiPQi8JbnK73LgWwQNdbi/readme
Start the BTFS Daemon
$ btfs daemon
Clone the go-btfs repository
$ git clone https://github.com/TRON-US/go-btfs
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 github.com/tron-us/go-btfs-common v0.2.28
go: extracting github.com/tron-us/go-btfs-common v0.2.28
go: finding github.com/tron-us/go-btfs-common 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 "github.com/TRON-US/go-btfs".CurrentCommit=e4848946d" ./cmd/btfs
Afterwards, run btfs init and btfs daemon to initialize and start the daemon.
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
$ wget https://golang.org/dl/$GO_PACKAGE
$ 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

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:
--publishasks Docker to forward traffic incoming on the host’s port 8080, to the container’s port 5001.--detachasks Docker to run this container in the background.--namespecifies 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"]'
E.g:
(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
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>

btfs uses a repository in the local file system. By default, the repo is
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:
- Main file: ./cmd/btfs/main.go
- CLI Commands: ./core/commands/
- libp2p
If you make changes to the protocol buffers, you will need to install the protoc compiler.
BTFS Gateway is a free service that allows you to retrieve files from the BTFS network in your browser directly.
