Ethosphere Timeline Update 6 June

4 Mins read

This is the weekly-ish post where we update the Ethosphere overall timeline. Let’s start with the commentary>>

Protocol updates:

No news seems to age more quickly than protocol news, but from last week’s All Core Devs call, the London / 1559 upgrade has been pushed back. We are now looking at a 28 July mainnet date due to the need to address an issue re: max fee caps. A new devnet, Calaveras, has been spun up to facilitate this testing. As always, Tim Beiko’s call summaries are strong. On the next call the revised block dates will be discussed/confirmed.

The Merge / Cancun – Assuming the first post-Merge upgrade is indeed Cancun, and that Cancun will include validator withdrawals, Vitalik thinks this should happen ~2 months after the merge. That puts a middle-ground estimate for Cancun at Q1 2022, as per the timeline already. Neat!

Sharding – For the recently wrapped up Rayonism hackathon, it was hoped that there would be bandwidth to progress a sharding prototype. This didn’t eventuate in the end due to the focus on merge devnets, but good news from the Eth2/consensus layer camp with the reveal that work on a sharding prototype is ongoing!

The upcoming consensus layer upgrade, Altair is currently on the 7th version of its Alpha spec. Hopefully this should be the final version ahead of testnets towards the end of June. Altair is looking likely for early August at this point as it is a week or two behind when the spec freeze was originally envisaged. Still solid progress nonetheless.

Layer 2 updates:

Offchain Labs has launched the mainnet beta for its optimistic rollups implementation, Arbitrum (or Arbitrum One, as they are calling this specific blockchain). They are opening this up to any and every developer keen to integrate. So far over 250 takers (including Uniswap who have already deployed on Arbitrum!) which is a massively positive signal. I’m guestimating the Arbitrum mainnet public launch somewhere in Q3.

In the previous update, I mentioned that Matter Labs’ zkSync was getting close to releasing. Indeed, it happened! ERC-20 and NFT swaps are available on testnets as well as the alpha version of the EVM-capable zk rollups tech zkSync 2.0. We now await public mainnet with zkPorter implementation later on this year.

Zk rollup/DEX Loopring has gone live with it’s 3.7 upgrade but not quite yet with Ethport. It sounds like they are bundling this up to go live with their next 3.8 release. Will keep this on the timeline for Q3.

MakerDAO, on a quest to integrate with absolutely everything, is getting pretty close to delivering their initial DAI / Optimism bridge. It’s now in final testing.

THE TIMELINE

Ethereum protocol upgrades / hardforks in bold.

All dates are moderately informed guesses by me, and should definitely NOT be viewed as commitments from the respective teams.
