The idea L2s are selling us is that they are actually as safe as the underlying L1. That is far from the truth, in mathematical terms it is like the distance from 1 to infinity.
So on most of L2s there is no fraud proofs, you simply trust the centralised sequencer. Or the admin key which can simply transfer all the funds. Protocols are hard to upgrade, what happens if there is a bug ? So teams are creating backdoors. But these backdoors are effectively the gun the state can use against all what is built, or you need to hack the sequencer, get into the server room where the sequencer runs, social attack on only one devOps dev who has the password for the sequencer.
Even if there is a small multi-sig, it still means that L2 is not as safe as L1, it is as safe as that small group from the multisig. This directly means, L2s in the current form are simply not here to scale L1, if you scale L1 you have no backdoor and you are as secure as L1.
There is simply no backdoor in a scalable, decentralised L1 like
#MultiversX . Funds are ultra safe, especially with guardians and
$ESDT, in-protocol token standard.
It is simply unbelievable how much money, effort, time is put into working on bad primitives, just because those teams, investors, VCs sees that they can earn the green dollars fast.
The vision of
#blockchain is simply much more. Be good, do good, develop something magical.
