This change clearly is made in benefit of whole Cryptocurrency’s ecosystem. LTC MWEB is not the only implementation of Mimblewimble (there’s also Beam and Grin), nor will be the last one.
MWEB could also be implemented on Bitcoin as well, which could clearly have a “btcmweb” prefix.
We haven’t been able to check if there have been action on this address and that’s a good thing.
Does anybody know how much this address holds? NO!
Also, by using ‘ltcmweb’ we can make litecoins’ address more foolproof. The first three letters are still ltc, so software can be used to handle the addresses not making it super difficult for users to select the correct layer.
