Light client
A client that checks selected blockchain information using compact proofs and protocol-specific assumptions.
In more detail
A light client trades some independence for lower data and storage needs. It can verify particular claims, such as transaction inclusion, without processing everything a full node does. The important question is what it actually checks and how it obtains trustworthy headers; those assumptions vary between protocols.
How you might use it
A lightweight wallet checks a Merkle proof that its payment appears in a block, without downloading every transaction in the chain.
