*5.3.4 Legal and regulatory concerns*

The distributed nature of blockchains gives rise to some unique legal concerns. Since different nodes of the distributed ledger may be located in different regions of the world, it is a complex and even conflicting task to decide which laws should be complied with and which courts have the authority to decide what matters in blockchain-related issues [29]. The blockchain pilot initiators should collaborate with legal professionals to define rules and a detailed set of contingencies to anticipate potential legal issues [13].
