  The disruptive power of blockchain technologies represents a great
opportunity to re-imagine standard practices of telecommunication networks and
to identify critical areas that can benefit from brand new approaches. As a
starting point for this debate, we look at the current limits of infrastructure
sharing, and specifically at the Small-Cell-as-a-Service trend, asking
ourselves how we could push it to its natural extreme: a scenario in which any
individual home or business user can become a service provider for mobile
network operators, freed from all the scalability and legal constraints that
are inherent to the current modus operandi. We propose the adoption of smart
contracts to implement simple but effective Service Level Agreements (SLAs)
between small cell providers and mobile operators, and present an example
contract template based on the Ethereum blockchain.
