description: >-
Peers have the option of setting filters on each connection they make after the version handshake has completed.
Bloom filters are for clients implementing SPV (Simplified Pament Verification) that want to check that block headers
connect together correctly, without needing to verify the full blockchain. The client must trust that the transactions
in the chain are in fact valid.
