Setting up Swarm

To run swarm you first need to install geth and bzzd which is the swarm daemon.

go get -d github.com/ethereum/go-ethereum
go install github.com/ethereum/go-ethereum/cmd/geth
go install github.com/ethereum/go-ethereum/cmd/swarm

Now we'll generate a new geth account.

$ geth account new

Your new account is locked with a password. Please give a password. Do not forget this password.
Passphrase:
Repeat passphrase:
Address: {970ef9790b54425bea2c02e25cab01e48cf92573}

Export the environment variable BZZKEY mapping to the geth account address we just generated.

export BZZKEY=970ef9790b54425bea2c02e25cab01e48cf92573

And now run swarm with the specified account to be our swarm account. Swarm by default will run on port 8500.

$ swarm --bzzaccount $BZZKEY
Unlocking swarm account 0x970EF9790B54425BEA2C02e25cAb01E48CF92573 [1/3]
Passphrase:
WARN [06-12|13:11:41] Starting Swarm service

Now that we have the swarm daemon set up and running, let's learn how to upload files to swarm in the next section.
