a previously undisclosed upgrade
Hey, I disclosed it nearly two weeks ago! These guys really need to keep up to date with "What's New in Eth2": https://docs.google.com/document/d/1oMi-0ZbCD5SdBtMxtHC5gaiflX8MnXGF1_Nk-_gGIUI/edit#heading=h.7kxmdua1kdlr
@5chdn The first secret meeting was an ewasm catchup with totally random people sitting on the floor in devcon in one of the public rooms (Fredrik was there too), where we talked whether ewasm could help Ethereum get a bit more performant. That devolved into me telling people about ideas I've been sitting on for data reduction, and all the complications why it's hard. Alexey lso had some ideas he's been sitting on. We agreed to follow up.
[The second secret meeting was Me, Felix and Martin discussing ideas at dinner that day.]
The 3rd secret meeting was actually organized by the research team to talk on the Ethereum 2.0 progress Parity and Pantheon has been making, and how to motivate it. Hence why Joe was there. Fredrik was again there. I hijacked that meeting and told people that Eth 2.0 is nice and all, but can we try to do something while 2.0 arrives so that 1.0 gets better and doesn't just survive? The meeting wasn't organized to talk about these things. Ihijackedthemeeting**
We totally ran out of time (had 1h), so agreed to pick it up the next day, when we were kicked out again from the building, so we delayed again and had our 5th "secret" meeting at 9am the next day. Since we couldn't figure out anything meaningful, we agree to try to dream up some EIPs, but since it's a lot of work for a single person, we figured we can form groups to pop ideas back and forth. That's what's been "decided", to draft up an initial idea to publish publicly.
The last secret meeting was a handful of us sitting in the "food court" at devcon (where everybody else was, ate, etc) and talked about how we could solve some problems.
That's your conspiracy theory.
