Ethos is a decentralized, Bitcoin-like network for storing and sharing valuable information. We provide transparency, control, and ownership over personal data and its distribution. Validation and maintenance is distributed throughout the data community and automatically maintained without needing a safe deposit box or a commercial site. What Bitcoin has done for currency and BitTorrent for media, Ethos does for personal data. Nodes in the network are incentivized by collecting transaction fees, coinbase transactions ("finding blocks"), and proof-of-storage fees to sustain the distribution of personal data. Fees are paid with the underlying cryptocurrency represented by the network, also known as "PrivacyCoin." The role of nodes, besides the usual proof-of-work, which protects against "double spending," is to maintain shredded pieces of information and present them to the network on-demand.
