We have Lightning Network, MAP Protocol (MAP), Liquid Network, Rootstock and Stacks in addition to sidechains so the features provided by these networks are what will determine the number of users but the majority will prefer Lightning Network for low cost daily transactions. It is not a hard fork so it does not need network consensus.
Didn’t know we had a lot of them already, the LN seems to have cast a dark shadow on the rest and they don’t even get to make a name for themselves. Good to know this Nakamoto Bitcoin upgrade thing is a network just like LN which makes it outside of Bitcoin and a fully optional use.
I don’t see it to be what Bitcoin users actually want. Eventually, a lot of users or investors would want their transactions done on the Bitcoin blockchain and not some side network that would be a bridge to Bitcoin network.
