The core devs are still arguing about Amsterdam on devnets.

Meanwhile, you can npm install it and run the whole thing tonight. 😏

Repost tweet 1 if "stack too deep" ever cost you an afternoon. 🫡

And — what's the cursed-est stack-too-deep workaround you've ever shipped? 👇 7/7

[EthereumJS @EFJavaScript]

"Stack too deep."

The two words that have ended more Solidity sessions than failed audits. 😤

Amsterdam's EIP-8024 gives the EVM more hands to reach deeper into the stack — the fix starts at the bottom. 🧵 1/7

[EthereumJS @EFJavaScript]

Bigger picture: less "stack too deep" means simpler, more readable contracts and fewer ugly workarounds — stack-packing structs, via-IR gymnastics, splitting functions just to appease the compiler.

Spec by @frangio_, with Vyper's Charles Cooper (@vyperlang), @chfast & @axic.

Things to build now that the block keeps receipts: parallel executors, conflict detectors, trace-free indexers. 👀

Receipts engineered by @nero_eth (follow him — he posts BAL research like a weekly newsletter), @dankrad, @JochemBrouwer96 & @ignaciohagopian. Devnets by @ethpandaops.

Experimental — play, don't deploy the rent money. 🧾 https://t.co/Iz4bVX67Ud https://t.co/YWIMgVPYsn https://t.co/tQM0waUjIu 9/9

For years, every Ethereum block has handed you a 32-byte hash and gone "trust me bro, I did the math." 🫠

Amsterdam's EIP-7928 finally sat the block down and said: show me the receipts. 🧾

Day 2 of Amsterdam Week — and yes, you can run one yourself today. 🧵 1/9

Skeptical of a receipt someone just handed you? Healthy.

Generate it on one node, pass it to another, check it against execution + the header hash. Forged receipt = block rejected.

The whole vibe of EIP-7928 is "verify," not "trust me bro." 🧾✅ 8/9

[EthereumJS @EFJavaScript]

This week we go one EIP at a time — runnable examples, not whitepapers.

First up, today/tomorrow: Block-Level Access Lists. 🧵 soon.

So: npm install, set the flag, and go break something experimental. That's literally what it's for. 🇳🇱⚡

New to Amsterdam (a.k.a. "Glamsterdam")? It's the fork after Fusaka, themed around scaling L1 execution and cleaning up gas accounting.
