(Alice & Bob Podcast #10): Universally Composable Multiparty State Channels

There are numerous payment channels constructions and they may be based either in the account and UTXO Models. Moreover, some of construction were not shown to be composable, meaning they are secure in the presence of other protocols including instances of its own. This security notion is very important in the design of protocol.

Alice and Bob discuss a novel notion under the universally composability framework which is general enough to either account and UTXO Model based isomorphic multiparty state channels. This new notion was shown to work with a concrete protocol, in the case the Hydra Protocol and its extension! In other words, we show that Hydra Protocol is composable.

Their discussion is in here.

Have fun!
