Re: [CHAIN] Chain 2.0

Hi Steve!

thanks a lot for moving things forward, very appreciated and I personally
thank you.

Sorry for the late reply - unfortunately my OSS involvement decreased in
the last months due to my new job, I hope to get better organised soon, in
order to get back contributing ASAP.

I am not sure that feature would fit in the commons component, however
if Christian
is submitting a patch that contributes that functionalities in
commons-chain, I am open to apply it

That makes perfectly sense, I second you - just give me the time to have a
deep review to the codebase, so I can cut the first RC.
