IPFS and the Blockchain are a perfect match! You can address large amounts of data with IPFS, and place the immutable, permanent IPFS links into a blockchain transaction. This timestamps and secures your content, without having to put the data on the chain itself.
Augur is a trustless, decentralized oracle and platform for prediction markets. The outcomes of
Augur’s prediction markets are chosen by users that hold Augur’s native Reputation token, who
stake their tokens on the actual observed outcome and, in return, receive settlement fees from
the markets. Augur’s incentive structure is designed to ensure that honest, accurate reporting of
outcomes is always the most profitable option for Reputation token holders. Token holders can post
progressively-larger Reputation bonds to dispute proposed market outcomes. If the size of these
bonds reaches a certain threshold, Reputation splits into multiple versions, one for each possible
outcome of the disputed market; token holders must then exchange their Reputation tokens for one
of these versions. Versions of Reputation which do not correspond to the real-world outcome will
become worthless, as no one will participate in prediction markets unless they are confident that the
markets will resolve correctly. Therefore, token holders will select the only version of Reputation
which they know will continue to have value: the version that corresponds to reality
