The Merge is a monumental achievement

But we don’t think PoS Eth will have reached its final form post-merge

Introducing Goldfish 🐠, a provably secure variant of fork-choice that could lead to an even more secure chain 💪🧵

paradigm.xyz/2022/09/goldfi… A relatively tricky component of Ethereum’s PoS consensus protocol is its “LMD GHOST” fork-choice rule.

This protocol has been through multiple cycles of attacks and patches:

Data availability (DA) is critical for blockchains and rollups.
DA sampling is a deceptively simple and elegant proposed solution.
But actually, a lot of R&D challenges still need to be figured out! 🧵👇
paradigm.xyz/2022/08/das Data availability (DA) is crucial for blockchains and rollups. An oft-discussed technique is random sampling for data availability verification (DAS = DA sampling), popularized by a paper by @musalbas @alberto_sonnino @VitalikButerin.
