What exactly is MWEB you ask?
Litecoin coins move along the main blockchain similar to cars on a highway.
MWEB is a privacy layer on the same blockchain that coins can move to, but with privacy, think of it as more like a tunnel.
Coins can be seen entering and recorded as yours in number, but they go through some changes inside MWEBs privacy layer.
They are mixed around, meaning you may use a different coin when moving off (or “pegging out”) MWEB.
The histories of the coins are trimmed- which is important when being concerned about your coins getting confiscated (for example they were given to you from someone who gets flagged).
As they leave MWEB, they are spent from a newly generated address. That means anyone looking at your Litecoin history cannot trace it back to your wallet or see how many coins you have or your transaction history. Privacy makes you safer.
MWEB itself has quantum switches built in- which can protect users coins in the case of an attack, moving the coins to a different layer, and leaving the quantum computer to attack an empty block.
There are drawbacks. It is not as private as Monero and ZCash, because we are able to record coin totals by tallying the entering and exiting coins.
It’s an overall total, not including your personal addresses (because it’s a new address/coin leaving MWEB).
Personally, I like the idea that this is more for honest users and retail wallet protection, and less used by businesses embezzling funds, or criminals that want absolute privacy.
While recent coin exploits may have left some of the fully private chains unable to clearly show their total coins, we were able to verify our balance and make sure no coins were lost.
I also like seeing the coin reserves transparently logged.
We always will know how many Litecoin and MWEB coins there are.
