If non segwit nodes view segwit transactions as anyone can spend ,why can't you broadcast a segwit transaction using them?

2

Segwit was designed in such a way that segwit transactions, after removing the witness, are valid but non-standard to old nodes.

This guarantees that old nodes won't reject such transactions when they're seen in blocks, but still won't be relayed or mined by old software.

  • Does this apply to all SegWit transactions, including P2SH-nested types? – Chris Chen Jan 29 at 16:21

    @ChrisChen Indeed. All segwit spends violate the "clean stack" standardness rule implemented by most pre-segwit Bitcoin Core versions. – Pieter Wuille Jan 29 at 19:04
