It's been a big year for Ethereum — with The Merge heralding the switch from Proof-of-Work to Proof-of-Stake.
But there are still issues looming for the network, issues significant to the health of the entire industry, with scalability chief among them.
But then, scalability is not the only problem that needs to be addressed.
It is hard to optimize their smart contracts for their applications' innovative features, and they cannot code on top of rich open-source components like their colleagues on mainstream do.
Can you simply explain what rollups are, and the role they'll play in the future of blockchains?
We created Cartesi Rollups to address the limitations of computational scalability and programmability, as we discussed previously.
