Monero: Public Keys of spent TXOs

<p>Monero&#39;s untraceability is based on the sampling of decoy inputs for each real transaction input. If a decoy input is a reference to an output which is known to be spent, it does not contribute to the size of the anonymity set of the real input. To prevent the sampling of spent outputs as decoys, the blackballing tool (released together with Monero v.0.12) can be used.</p> <p>This data set provides a list of public keys which should be avoided as mixins. It consists of the following three files:</p> <ol> <li>Monero TX outputs which are known to be spent (spent_outputs.csv)</li> <li>Monero TX outputs which are at risk of being identified as spent, due to occuring in a ring with only 2 or 3 possible inputs (risky_outputs.csv)</li> <li>Monero TX outputs which may have been spent on either the MoneroV or the Monero Original blockchain and are therefore at a higher risk to be identified. (referenced_on_fork.csv)</li> </ol>
