look, you made it such deliciously low-hanging fruit that i couldn't not fix your graph for you *in keeping with your format, i only grabbed major milestone releases *comparing number of releases seems like pretty silly data
6 solana client updates in 15 months. outstanding work @anza_xyz for making shipping look effortless
The goats at @ethPandaOps spent a days spinning devnets for us to test a PoC of RLNC for Ethereum mainnet. @parithosh_j @BarnabasBusa @_pk910_ @samcmAU were directly involved, but the whole team built up the tools to be able to quickly deploy 1000 nodes ethresear.ch/t/faster-block…
90% of attestations arrive within 2 seconds. 6-second slots are comfortably achievable! The chart shows when attestations were first seen during the last 100 missed slots. (Missed slots provide clearer timing data, as all clients attest at the same time)
My goal: 6s for Glamsterdam 4s for (Glamsterdam +1) ... The headline target will be 1s. Beyond 4s we need to do some deeper changes to consensus, which we're still working on.
How is it that the most performant execution clients are implemented in C# and Java? There’s always so much hype around Rust and Go and endless jokes about Java. And yet…
Besu is now the 2nd fastest EL client on Ethereum 🚀
We have already worked on this topic within Besu. We implemented a mechanism that allows for a set of RPC nodes without the Merkle tree. The performance is good, and the node size remains small thanks to only storing the flat state.
Approaching 800 TPS on the Ethereum Ecosystem! 🚀

People don’t want that banks can freeze their accounts. People don’t want to be censored on social media. People don’t want to be blocked by a website because of where they live. Self custody and decentralisation are just tools to achieve what people care about.
99.9% of people on this planet don’t care about self custody we’re just not ready to admit it yet the sooner we start meeting users where they are, not where we wish they were the sooner crypto actually gets adopted

1/ Protocol Guild’s new brand, logo, and website are live! Our mission remains the same: To secure Ethereum’s future by funding core developers. We will safely scale Ethereum to be long-term infrastructure for the world.
Besu completed the migration from PMT to Verkle on Hoodi and is following the head. As we can’t compare our state root with other clients yet, we’re using Pectra’s gas cost rules to compare gas usage between PMT and Verkle blocks. Next, testing with a bigger testnet @StatelessEth
Funny how the Vatican got exempted from reciprocal tariffs and a month later we get the first Pope from Chicago. God works in mysterious trade deals.

Let's gooo, besu numbers below. This is one specific use case, but interesting to see how high can go the throughput. x.com/vdWijden/statu…
Since other clients are also bull-posting about their results on the perfnet, check this out: 10GGas/s (caveat: this is a very artificial scenario, usual speed is at ~500Mgas/s and dips to 150Mgas/s in certain scenarios)
As is tradition, Vitalik and the rest of the core devs will be sealed in a chamber today to commence the Pectra hardfork. Should the hardfork be successful white smoke will emerge. Black smoke will emerge if it's a failure.

Does anybody know how many independent entities currently run at least one Ethereum validator? AFAF x.com/barnabemonnot/…
2) Eth doesn't do irregular app state transitions. These are centralized af.
People are missing the important points in this Solana emergency fork situation 1) Eth has client diversity and a protocol spec steered by a meaningful research community. The most popular eth client, geth, has at most 41% market share. Sol has one prod client (just one; don't…
It’s a pivot not a reprioritization. Whenever scaling L1 was brought up in the past, many core devs said that we should use all resources for blob increases only. Even in Sassal’s roadmap L1 scaling only comes after having a zkEVM, which obviously we don’t have on mainnet.…
We discussed this at a Token2049 panel--most call it a pivot, but insiders frame it as reprioritization. I honestly think it's better for Ethereum to call it a pivot. The market *wants* Ethereum to call it a pivot. Calling it reprioritization seems like saving face. Showing…
