This Mimblewimble paper was introduced last month by Tom Elvis Jedusor.
It appears that the system will not work with Bitcoin (on chain)
The first thing we need to do is remove Bitcoin Script. This is sad, but it is too powerful so it is impossible to merge transactions using general scripts.
The system would provide inferior privacy to RingCT because RingCT provides untraceability that CoinJoin and CT cannot. Are there any pruning concepts from Mimblewimble that could benefit Monero? If so how would those potential savings in compare to the type of database pruning already in production with Aeon?
