why not check for yourself? It's not that hard to keep up with the activities of EF teams, as most of it happens in the open: - Applied Research Group hosts ACDC and posts actively on ethresearch, and both @ralexstokes and @mikeneuder are active here and in various other community forums - The Account Abstraction team contributes to many repos & EIPs (e.g. 4337, 7702), and their contribution will be obvious to anyone who works on wallets or has touched AA over the years - @yoavw is the right person to follow here - Consensus R&D is also very active (contributing to community calls and on ethresearch), and people on this team like @dankrad and @drakefjustin are similarly pretty vocal and open about their work - Cryptography Research publishes their work here: crypto.ethereum.org/research - Devcon's work product probably speaks for itself. This week some of the team are busy with site visits for next year. - @austingriffith's work on developer growth is similarly very public, follow @buidlguidl as well if you want to keep up. - The Ecodev coordinators team is more of a support function for other teams, and their outputs are usually bundled with the work of other teams (e.g. helping raising money for important initiatives like the recent security attackathon, or helping improve EthMagicians, etc) - @EF_ESP manages the entire grants apparatus of the EF, including regular inbound through the open program and they publish quarterly recaps on the blog + info on their website regularly (esp.ethereum.foundation/) - @ethdotorg's work is similarly visible and easy to follow along with on github github.com/ethereum/ethereum… - @go_ethereum's work is also all available on github github.com/ethereum/go-ether…, and obviously you will see geth team members on many ACDE calls and similar forums - @teamipsilon's work is also very easy to follow on github github.com/ipsilon - @EFJavaScript is the same github.com/ethereumjs - @EFNextBillion publishes their work here nxbn.ethereum.foundation/ - @ethPandaOps is well known for their high rate of output and value to the ecosystem, you can learn more about them here: ethpandaops.io/ - Portal Network you can also follow along on github github.com/ethereum/portal-n… - Privacy & Scaling Explorations (more of a group of teams than a single team) publish tons of info about their work here pse.dev/, and you can find the github repos of various PSE projects on that site - Protocol Security's work and output is also very obvious to people involved in this domain - more about the team here github.com/ethereum/protocol…, and follow @fredriksvantes who leads the team if you want to see regular updates - Protocol Support's work is also very visible (e.g. running ACDE, running the Ethereum Protocol Fellowship (github.com/eth-protocol-fell…), and lots more) and @TimBeiko is obviously the easy follow here. - @EthereumRemix's work is also very public github.com/ethereum/remix-pr… - Robust Incentives Group publishes info about their work on their website here rig.ethereum.org/, follow @barnabemonnot if you want to keep up - Snake Charmers (i.e. Python) team also works in the open, blog posts here snakecharmers.ethereum.org/ and their work is spread across a few different repos like github.com/ethereum/web3.py, github.com/ethereum/eth-util…, and several others - The Specs & Testing team manages much of the extensive testing and spec work to ensures that each hard fork upgrade to Ethereum goes off without any issues - their work is most visible to those close to protocol upgrades, but you can learn more here github.com/ethereum/tests and here blog.ethereum.org/2023/08/29… That's every team at the EF, aside from ones that are already spinning out (see @argotorg) and operational functions like legal, finance, people ops, devops, and opsec which are together ~20 people. We have a pretty thin operational layer for an org of ~250 people.
