Mimblewimble Non-Interactive Transaction Scheme
Gary Yu
Abstract
I describe a non-interactive transaction scheme for Mimblewimble protocol, so as to overcome the usability issue of the Mimblewimble wallet. With the Diffie–Hellman, we can use an Ephemeral Key shared between the sender and the receiver, a public nonce R is added to the output for that, removing the interactive cooperation procedure. And an additional one-time public key P' is used to lock the output to make it only spendable for the receiver, i.e. the owner of P'. Furtherly, to keep Mimblewimble privacy character, the Stealth Address is used in this new transaction scheme.
Note: A major updating on the scheme, and analysis on replay attack and rogue-key attack, etc., to substitute the unsafe previous version.
