How can I run Bitcoin core testnet version on ubuntu 16.04 platform ? I am getting so many reference about how to run bitcoin core mainnet but it will take around 20 days to synchronize with the network as per my bandwidth and also will take my half of the HDD. So I opt for Testnet. Can someone explain me how to insatll bitcoin core testnet on Ubuntu 16.04? I would be grateful. Step by step explanation or reference would be much appreciated.
After having installed Bitcoin core on your machine, run the following command to start synchronising the testnet blockchain
bitcoind -testnet -daemon
The synchronisation starts as a daemon and runs in the background, you can issue the following the command to see the progress
To access the command line apis , just add the -testnet parameter
bitcoin-cli -testnet getinfo
Update: The RPC getinfo is deprecated, use getblockchaininfo for it to work with the latest version
bitcoin-cli -testnet getblockchaininfo
