Time for BCH to look at MW MWEB Extention Block For Scalling & Privacy Upgrade

Just as Litecoin (LTC) can easily implement it without too much de-listing due to its size

BCH can do better

It is a SF and uglier than SegWit at that

==Abstract==

This LIP introduces opt-in MimbleWimble (MW) as a new transaction format through extension blocks (EB). Extension blocks run alongside main chain canonical blocks at the same interval of 2.5 minutes on average. Inside the EB is where MW transactions occur. Users can opt-in to using MW by moving their coins in and out of the EB through an integrating transaction.

To transition coins from the canonical side into the EB, it must be pegged-in. Coins on the canonical side are sent to a specially marked anyone-can-spend address. This results in the redemption of the equivalent amount of MW coins inside the EB. Once inside, MW transactions can occur. Coins in the EB can also be pegged-out back to the canonical blockchain and will be sent out of this special address. This special address will hold all the coins that represents coins on the extension chain.

@bitcoincashautist fine MW can come to BCH in the form as HF

BCH gets the extra scaling + privacy (along with Zside plan)

sure someone could figure it out how to properly HF MWEB into BCH
i would say best not to discount it (since we already have zcash orchard drivechain plan)

Please be more elaborate, this is Bitcoin Cash Research website, we do research here, not hanging out like on Telegram.

What are the

Potential Benefits
Technological specs
Potential disadvantages

of this technology?

I would agree with @bitcoincashautist that the implementation of this soft fork (extension blocks) adds so much unnecessary complexity. Besides what are the potential benefits and tech specs of the scheme you are presenting here exactly in the form of HF? You have to be specific.

I think implementing a smart contract that can verify ZKP transactions would be superior and less costly than MWEB. Also, I think a similar idea for Monero as a BCH sidechain would be more appealing
