There are blockchains that are optimized for financial utility, then there are blockchains designed for data storage and – in the case of ARPA chain – there are blockchains for multi-purpose private computing. Using distributed computing, which they call “multi-party computing,” ARPA makes it possible to send your data to another computer without revealing what information is being shared. Using this capacity, ARPA wants to make it possible for your personal information to make you (and not an advertising company) money. You can anonymously share sensitive information, and with the power of ARPA chain, be compensated for doing so. There are other potential use cases too, like securely sharing sensitive medical records that employ ARPA chains unique privacy protocols to simultaneously share and protect information.
