Recent updates by the Bitcoin SV Infrastructure Team have unlocked several new use cases for specialised transaction types: consolidation transactions have paved the way for nanopayments, while dust return transactions will keep wallets clean and eliminate dusting privacy attacks.

In this session, Steve Shadders and Matej Trampuš will explore a range of different use cases for these specialised transaction types, including covering the mechanics of how each of these transaction types are assessed, accepted and propagated.
