=== Abstract ===
  : //This BIP defines new messages and serialization formats for propagation of transactions and blocks committing to segregated witness structures.//

=== Motivation ===
  : //In addition to defining witness structures and requiring commitments in future blocks ([[https://github.com/bitcoin/bips/blob/master/bip-0141.mediawiki | BIP141 - Consensus segwit BIP]]), new mechanisms must be defined to allow peers to advertise support for segregated witness and to relay the witness structures and request them from other peers without breaking compatibility with older nodes.//
