Hi Matthias,
I've downloaded and read the federatedblockchains draft.
I think it's a good move to get a broader awareness and
better and solid services base of crypto currencies in common and europecoin specific.
The understanding and knowlegde of cryptocurrencies is still mostly in the hands of the ICT people.
But to join efforts, knowledge and experience with others to create the 'federated block chains'
seem to be a very good idea.
To get the majortiy aware of the posibilities of cryptocurrencies and get an easly acceptance, the technical
side must be easy to use and running smoothly.
I don't know if you ever looked at the Guldencoin, but their (android and iphone) Wallet implementation is impressive and
easy to understand for first time crypto users. (see

A small report back on the current Windows wallet:
The current windows wallet is still working excelent.

Staking is also working perfect for a few days now.

Keep up the good work!
Jerry
