SE or an SAP affiliate company. All rights reserved. 54Public No intermediaries & Robustness Disintermediation / trustless exchange / no intermediaries Due to the fact that data cannot be changed and it is visible to everybody – no intermediaries to spend trust are required – simply – once stored, data is visible, and trusted by everybody – clearly a gamechanger Robustness Due to the fact that the blockchain is distributed amongst multiple (in some cases thousands) nodes it very hard to: –DDoS it – it is not like you are attacking a single or even several data centers – Hack it – even if for some reason one or many nodes decide to send fake data, this will be discovered by the rest of the network, and blocks generated by them would be discarded – Bribe it – there is no one single entity that can modify it, so bribery is out of scope
