Sometimes, upon returning from abroad, a traveler meets a solid bill from the home service provider. According to the employees of telecommunication companies, the problem is in the modern roaming communication — they are unable to quickly block the number.

However, today the telecommunications blockchain platform Bubbletone is being created, and it will cancel roaming and all related problems — high cost, forced change of sim-cards, etc. Bubbletone will provide direct communication between operators, service providers, subscribers through smart-contracts.

The structure of Bubbleton implies the creation of an ecosystem consisting of a certain number of powerful servers (nodes) that are managed by the community. Any owner of the cryptocurrency can start earning on the processing of smart-contracts by purchasing a license for node.
