Full clients verify transactions directly by downloading a full copy of the blockchain over GB as of January [update]. Full clients check the validity of mined blocks, preventing them from transacting on a chain that breaks or alters network rules.

Lightweight clients consult full nodes to send and receive transactions without requiring a local copy of the entire blockchain see simplified payment verification — SPV. This makes lightweight clients much faster to set up and allows them to be used on low-power, low-bandwidth devices such as smartphones. When using a lightweight wallet, however, the user must trust full nodes, as it can report faulty values back to the user.
