Install & Run BTFS2.0 Node

Install BTFS 2.0

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.

Build from Source
Clone the go-btfs repository
$ git clone https://github.com/bittorrent/go-btfs

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

Run BTFS

Initialize a BTFS Daemon
navigate to the btfs director cd cmd/btfs

$ ./btfs init

to get started, enter:

	btfs cat /btfs/QmZjrLVdUpqVU6Pnc8pBnyQxVdpn9J8tfcsycP84W6N93C/readme

Start the Daemon
Start the BTFS Daemon
$ ./btfs daemon --chain-id <chainid>

Specify the chain for btfs to run by --chainid, the chainid of the test network is 1029, and the start command becomes: btfs daemon --chain-id 1029

$ ./btfs daemon --chain-id 1029

Run the Daemon
When starting the BTFS daemon for the first time, the system will create a node account and at the same time print a string of messages: cannot continue until there is sufficient (100 Suggested) BTT (for Gas) available on After seeing such a message, it is necessary to recharge the node account with BTT through an external account, and the system suggests a minimum of 100 BTT, which is used as gas to deploy a node vault contract by the node account.

BTT test token application address: https://testfaucet.bt.io

After the recharge, the BTFS node will create the vault contract

At this point, the BTFS node is up and running

Note:

the node address and private key need to be saved, and the private key needs to be kept private and secure.
The vault address needs to be saved, look for the self vault field in the print message, the address after it is the vault address.
