Ethereum core devs have a call coming up this Thursday to discuss getting EIP-4844 to be considered for inclusion (CFI). This is a huge moment for the many teams that have been working on getting this EIP to production this year! Here is why I think it's time for CFI 👇

Optimism just enabled 4844 a few min ago. From $0.32 to $0.0004 for a transaction! Will rise over time as blob congestion picks up; but looks incredible to see how cheap we can make Ethereum!

EIP-4844 is more than a tech upgrade. It’s a substantial shift in how Ethereum core dev works at all, improving the relationship between research and client teams, and welcoming L2 core devs! It might be the most important moment in the transition to the rollup centric roadmap!

Reminder: EIP-4844 adds a new fee market to ethereum for short-lived data. Rollups would use this for data availability instead of hijacking regular gas. This is a GAME CHANGER for the rollup-centric roadmap, as fees could be lowered ~100x.

The base fee on @base is spiking right now! In other words, the chain is seeing an exponential growth in demand. Exciting stuff, but it also means to sustain this level of demand that now we’ve got to scale the compute layer of the OP Stack.

EIP-4844 update. L2s use ~400 MB / day of calldata right now. The EIP specifies ~2.75 GB / day in blobs. So, we're looking at ~7x more data capacity than today. We don't know for sure: - How cheaper L2 txs affects demand? - How separating gas/data markets affects prices?

Adding a relatively small amount of data to Ethereum this year (as part of the hard fork in Q4) enables users to have have ~$0.01 fees for most transactions without sacrificing safety or decentralization. EIP-4844 is a no-brainer. 👇

Now, I do want add that CFI does not mean "included" in the next hard fork. What gets decided in Shanghai is a separate process. However, given 4844 and withdrawals both span the across the CL and EL layers, there does seem to be good reason to consider it for Shanghai.

Surprised I haven't seen this before, but Metal is a great tool for visualizing smart contract deployments! Here are the Bedrock contracts, for example.

Let me explain each piece. First, 4844 is built on the withdrawals spec. Both the execution layer and consensus layer work has been built directly on top of the existing withdrawals implementations. There is no rebasing needing; it’s purely additive.

Coinbase has been a fantastic open source contributor to work with on shipping EIP-4844! If you want to follow along, check out for links and updates

Excited to share @coinbase ’s public support and contributions to EIP-4844, an upcoming improvement to the Ethereum protocol that will scale layer 2 rollups by increasing transaction throughput and decreasing fees 10-100x.

Optimism reinvests its profits into the OP Stack. It’s akin to Amazon‘s strategy of reinvesting all of its profit into future growth. Unlike Amazon’s closed source value capture, Optimism is free and open source and owned by the collective, not a handful of shareholders.

If blockchains are like cities, then it only makes sense to connect them together with shared world-class infrastructure. Some great analysis here motivating today’s decision by @LiskHQ to join the @Optimism community!

Great product opportunities now for builders as consumer crypto interest picks up - Frames Ads (load targeted ad for a user in a frame, click next to continue) - Frames Pay, like Shop Pay, make it one-click to sell onchain - Frames Permission (token gating, check history)

Here's an example of one possible model for frame-to-frame composable communication: dapps could provide a "Frame API" for checkouts and other types of transactions, served from their own domain. (Diagram for ants 🐜)

The spec has 9 months of intense iteration on it and the remaining changes are very minimal. Most client teams have already reviewed (+ implemented) it, even! Plus, there are complementary consensus layer and engine API specs.

One of the best parts of the ethereum ecosystem is how incredibly creative and productive we can all be when we’re aligned on a few useful open source primitives. e.g., JSON-RPC, ERC20/721, AMMs, ethers, safe, solidity tests, rollup bridges, ENS, KZG, 4337, 4844, …
