Total clients check the validity of mined blocks, preventing them from transacting on a chain that violates or alters network rules.95 Due to its size and complexity, downloading and verifying the entire blockchain is not acceptable for computing devices. .
Lightweight clients consult full clients 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 install and allows them to be utilized on low-power, low-bandwidth devices like smartphones. When using a lightweight wallet, but the user needs to trust the server to a certain level, as it can report faulty values back to this consumer.
