Blockchain is not just a virtual currency
SMART CONTRACTS
implement themselves without legal advice. Two parties make an agreement, stating the terms in the contract. The smart contract functions as an algorithm, that will automatically move on to the next point, once a requirement has been fulfilled in the blockchain system.
DIGITAL VOTING SLIPS
prevent ballot rigging, as a voter can personally check if his vote has been registered. When the vote has been cast, it is added to the blockchain in an encrypted version. The voter can see his vote's code, but not the vote itself. The result cannot be hacked.
PERSONAL DATA
can be protected by blockchain instead of a password, such as in the case of e- commerce or "cloud" storage. In blockchain, data is encrypted, so it cannot be hacked and can only be passed on to others, when the owner of the data allows transfer through the system.
