Happy Monday!

Pray you are well.

Today I have learnt on Blockchains and I am delighted to share of. Learnt from Ashis Gadnis - BANQUAPP.COM and Ric Shreves.

Any persons in this community  in the field?

The last time this discussion was here it was CBK and Bitcoin rundowns and the Ministry. Globally a lot is happening.

The discussion is beyond financial services into data management, humanitarian data and refugee transfers services...and more.

This community needs to have sharp deliberations on this at this year's IGF.
