How does the definition of “cancelling” and “deleting” change in a distributed, decentralized, nonhierarchical knowledge infrastructure?<br />
<br />
For example, in peer-to-peer protocols the most that can be done is '''requesting''' to delete something from a node/peer, but there can be no way to ensure that any cached version of that something is still stored.<br />
<br />
Especially to counter authoritarianism, this becomes a powerful resistance to censorship, as it becomes virtually impossible to erase all sources of some specific information.<br />
<br />
In [https://en.wikipedia.org/wiki/Version_control_system VCS]s like git, removing something from a repository means '''adding''' a '''removal''' operation, yet the file is (almost) irreversibly engraved in the history of the repository, thus impossible to erase.</div>Tommi
