Most people will see this headline and move on, but Fusaka is one of those upgrades that changes the network quietly and permanently.
This upgrade brings PeerDAS, a new system that makes Ethereum far more efficient.
Instead of forcing validators to process entire blobs of data which is slow and expensive they now handle smaller pieces of the data.
It’s like turning one giant task into many tiny tasks that everyone shares.
Because of this, Ethereum can:
— scale faster
— handle more transactions
— reduce rollup costs
— keep fees more stable even during high activity
The rollup ecosystem benefits the most.
Optimism, Arbitrum, Base, zkSync, Starknet all these L2s rely on posting data back to Ethereum. If that data becomes easier and cheaper to verify, the whole L2 world becomes faster and cheaper for users too.
Fusaka shows that Ethereum is still focused on real infrastructure — not hype.
Every upgrade is making the base layer stronger, lighter, and more ready for mass adoption.
This is how a network prepares for the next decade.
