@jlspacemesh @iddo333 @tal-m - research task we need for the Spacemesh wallet.

avive commented 5 years ago

We need to figure out the PKDF algo for the wallet for Ed25519.

avive commented 5 years ago

Need research to provide guidance and research direction. @iddo333

avive commented 5 years ago

We have this bip as an example for such an algorithm https://cardanolaunch.com/assets/Ed25519_BIP.pdf

Need feedback from @iddo333 regarding which BIP to use or implement.

avive commented 5 years ago

@ barakshani this is obviously based on what signatures we are going to use.

We also need to consider Julian's paper here. It will be great if we can get 1 recommendation from the research team after they debated this between them and reached a recommendation.

Implemented for the testnet timeframe. See: https://github.com/spacemeshos/ed25519/pull/4
