In this post we explain how @ethereum simplified and lowered to cost to launch a new fintech company. Those new companies that use Ethereum and launch zk L2s validiums for example will be able to focus exclusively on product design and user acquisition while competitors have to

I recently met @tzhen from @flashbots_x. I have huge respect for what she’s built and for the research her team is doing. We can’t work together right now since @class_lambda has a defined strategy in the MEV pipeline space. But long term, I genuinely believe there are multiple

Upgrades like this highlight a simple truth: the real long-term bet is building on Ethereum.
The @ethereum Fusaka Upgrade is live on mainnet, fully supported and performing as expected on the Ethrex Client. We're proud to be part of this fork and are already looking toward Glamsterdam with even greater commitment. Huge thanks to everyone whose work brought us here.

Good news in @ethereum land. Solidity is finally growing up. ADTs, generics, traits, type inference, first-order functions. Inheritance getting phased out. Linear types and even theorem proving on the table. I’ve been very critical of Solidity because it always felt like a

New Ethereum @leanEthereum consensus client by @class_lambda. Last year I announced that we started @ethrex_client, a minimalist and fast Rust execution client. It is now running in production as one of the smallest and most efficient clients in the network. We delivered in the
New Ethereum Execution Client: Ethereum Rust. Here we go again. At the end of last year, we created a team of three people to implement a consensus client in Elixir. The client is already able to attest and produce blocks. We are fixing a few simple bugs and will be creating the
