Adding something that could be called "detached signing" to bitcoin-core, would that require a BIP? Idea: during signing of a transaction, wallet can call/pipe a executable, send some transaction relevant information, wait for response, done.

The same thing would work for smartphones (in case of a BIP) by using URL schemas (bitcointxsigning://<data>)

jonasschnelli: I was also thinking about this problem, specially in relation to multi party signing.

btcdrak: I was looking at it from a key/wallet separation point (hardware wallets). But I agree, you could also have some clever p2p network that could manage getting additional signatures in a ms

With the exception of Copay which relies on a centralised server which stored xpubs, there doesnt really seem to be a p2p, privacy conscious solution.

btcdrak: Right. Electrum also uses a centralized server...
< jonasschnelli>
But I guess it's hard to cover this in a p2p network
< btcdrak>
jonasschnelli: true, but multisig signing in any case is a total bear currently. It's no wonder that centralised services are able to sell themselves here.
