Did you know that the security lead at the Ethereum Foundation lives in Stockholm?
His name is Martin Holst Swende and he will be visiting us to give a very insightful talk about the security challanges Ethereum has to wrestle with.
We will also hear about the Shanghai attacks and some other recent attacks.
... and we will hear about the upcoming Metropolis release!
Martin is also a developer of the Geth client and will after his talk be leading a hands on workshop for us all to follow along on our own laptops about private networking using Puppeth.
So install Geth and get up to speed and you will likely learn a lot from this event!
