12. CHALLENGES The high energy consumption - Bitcoin uses a lot of energy. The scalablity issue - Bitcoin supports far less transactions per second than e.g. VISA. It opens up possibilities for money laundering - Some blockchains as Monero are anonymous. The question remains as to how far we want to bypass the middleman. Often he can also protect us, e.g. a bank can protact us to the extend that we do not transfer the money to the wrong person.

13. CONCLUSION Blockchain is a shared , replicated ledger . Blockchain can open up business networks by taking out cost , improving efficiencies and increase accessibility . Blockchain addresses an exiciting and topical set of business challanges , which cross every industry .
