A fixed prefix peer to peer network has a number of physical nodes. The nodes are logically divided into a number of storage slots. Blocks of data are erasure coded into original and redundant data fragments and the resultant fragments of data are stored in slots on separate physical nodes such that no physical node has more than one original and/or redundant fragment. The storage locations of all of the fragments are organized into a logical virtual node (e.g., a supernode). Thus, the supernode and the original block of data can be recovered even if some of the physical nodes are lost.
