There’s a couple of times i would read a project whitepaper and i would presume it’s just a stretch. I mean some recent projects are just rebranding what’s been done in the past years.

I came across this project Shardeum that claims to be an EVM-based L1 blockchain that uses dynamic state sharding to address scalability trilemma. To achieve low gas fees, high speed and a more decentralized system. Basically, it operates the sharding process.

Algorand also claimed to have solved the “blockchain trilemma” with PPoS(Pure Proof-of-Stake) but has this challenge been solved ?
