Finance:MimbleWimble
Mimblewimble is a blockchain protocol created to improve privacy, fungibility, and scalability of blockchains.
It was published[1] on July 19, 2016 under the pseudonym "Tom Elvis Jedusor" which is the French name of Voldemort from Harry Potter.[2]
The Mimblewimble protocol uses blinding factors of balancing inputs and outputs in a commitment scheme as private keys. Sender and receiver must interact to construct a joint signature to authorize a transfer of funds. Blocks in Mimblewimble have all their constituent transactions aggregated into one giant transaction, erasing the original transaction boundaries. The initial block download further benefits from cut-through, in which all spent outputs cancel against corresponding inputs, erasing most of the blockchain history.[3]
A provable security analysis for Mimblewimble is provided by Georg Fuchsbauer et al.[4]
The protocol powers several decentralized privacy-oriented cryptocurrencies.[5]
