One of the things necessary for a second realm is contract and other legal services without the need to relying on the state to provide them. Bitnation could be one such source
Bitnation is a Decentralized Borderless voluntary Nation. it relies on blockchain and peer to peer technology to provide governance services. Bitnation is still in development and adding features. thier website currently offers the services of a blockchain based public notary as well as an emergency ID.
A new service in development is Pangea which will create a marketplace for legal services letting people create contracts or provide arbitration service. One of the its central features will be a built-in reputation system and a system to reward a good reputation. it is also very secure using mesh-networking, end to end encryption, and ID are pseudoanonymous
all these services would be a great help in building the second realm not just on a local level but a global one as well
