THE biggest unsolved problem in crypto for the last decade has been how do we scale layer-1?
Specifically, how do you shard/partition layer-1 ledger state.
It has been a unsolved problem for so long, and so many BS "solutions" have been pitched, that most people have given up on decentralized layer-1 scaling being a solvable problem (and have turned to centralized and/or layer-2 solutions instead.
So yes, Kadena didn't focus on a problem that "no one else was working on" like Chainlink for example, and instead they focused on a historically impossible to solve problem that everyone agreed was the big problem to solve... and managed to actually ship the solution into production.
layer-1 scaling is a monumental advancement in crypto that will dramatically increase the capacity for the sector to grow... but it may be that crypto is basically full of shit and doesn't actually need scaling because it'll always be just hype. I don't believe it's just hype, I believe crypto is the start of something truly massive and global in scope... but I could be wrong.
It's possible that the core feature that everyone in crypto has talked about endlessly for the last decade -- decentralized layer-1 scaling -- doesn't actually matter. This could be down to crypto not actually knowing what it needs to succeed, or crypto never being widely adopted in the long run, or a host of other macro-level reasons all lead to the same place: decentralization doesn't matter and/or scaling doesn't matter.
the culture in crypto is kinda crap. There's 5+ years of nonsense to deprogram, specifically "POS is the only future" and we're up against a lot of influencers and "thought leaders" that have large vested interests in POS being the only future (despite KDA being evidence to the contrary). So it's gonna take time, because most of the biggest names have a lot to lose by even crediting KDA with shipping sharding.
