\begin{abstract}
The InterPlanetary File System (IPFS) is a peer-to-peer distributed file system
capable of sharing the same files with millions of nodes. IPFS objects are addressed by their cryptographic hash. Objects can include links to others, forming a Content Addressed DAG, with the same merkle-tree properties of systems like Git. IPFS paths are fundamentally immutable; changes propagate up the hierarchy generating new names for the new content. These properties are very useful for certain applications. However, many applications require mutable objects. This paper presents IPNS, a complement to IPFS that introduces mutable names using an SFS-inspired scheme.
