Ethereum’s Exciting Fusaka Upgrade is Here!

Brace yourselves, folks! Ethereum just kicked off its Fusaka upgrade, and it’s a game changer! Activated right at epoch 411392 at the delightful hour of 21:49:11 UTC, the Ethereum account popped in to say, “Hey, guess what? Upgrade in progress… Fusaka is live on Ethereum mainnet!” Talk about a dramatic entrance!

What’s the Big Deal About Fusaka?

In their cheerful announcement, the Ethereum team laid out the fab features of Fusaka, and let me tell you, they’re big! First up, we’ve got PeerDAS cranking out a jaw-dropping 8x more data throughput for those slick rollup networks! Can you say data overload? But wait, there’s more: we’re also getting UX improvements courtesy of the R1 curve and pre-confirmations, prepping us for scaling like a pro with a gas limit increase. And yes, the masterminds behind this will be keeping a close eye on everything for the next 24 hours because, you know, tech!

Vitalik Buterin Chimes In!

The one and only Vitalik Buterin took a moment out of his busy schedule to share his thoughts on Fusaka. He dropped some truth bombs, saying PeerDAS is like sharding, which means Ethereum can chaotically agree on blocks without making every single node handle a mountain of data. It’s like a party where everyone shares their snacks, but without letting one person hoard the whole platter! And if you’re worried about those pesky 51% attacks? No sweat! We’re talking client-side probabilistic verification here.

Sharding: From Fantasy to Reality

This isn’t just a fancy concept anymore; this is real life! Vitalik reminded us that sharding has been the unicorn everyone’s chased since 2015. Data availability sampling? Since 2017! With Fusaka, it’s gone from dream to an actual live mechanism keeping our precious data secure. But hold your horses, it’s not the final frontier in sharding just yet!

The Sharding Journey is Not Over

Our buddy Vitalik made it crystal clear that Fusaka is just the beginning of the journey. He pointed out three things we still need to tackle. First, sure, we can deal with O(c^2) transactions on L2s, but L1? Not quite there yet! If we want to really level up Ethereum L1, we’re gonna need some mature ZK-EVMs to step up to the plate.

Second, there’s this little thing called the “proposer/builder bottleneck.” It’s kind of a mouthful, but it boils down to needing all the data to build the entire block. So wouldn’t it be amazing to have distributed block building? I mean, sharing is caring, right?

Third, and here comes the blunt part, we still don’t have a sharded mempool. Yup, that’s still a thing we need. But hey, despite these little hiccups, Vitalik hailed Fusaka as a monumental stride in blockchain design!

What’s Next?

Now, in the next two years, we’ll have the chance to polish the PeerDAS mechanism, scale it up while maintaining stability, and push L2s into the stratosphere. And when those ZK-EVMs are finally ready to rumble? That’s when we’ll really crank up the scaling on Ethereum L1’s gas too!

In closing, big shoutout to all the Ethereum researchers and core devs who’ve put in blood, sweat, and tears to make this happen. For the Ethereum community, Fusaka is way more than just another protocol update. It’s the start of the sharding era right here on mainnet! So hold onto your hats, because it’s going to be a wild ride.

As of now, ETH is chilling at $3,194. Should we invest? Time will tell!
