An Overview of Decentralized Web Technologies as a Foundation for Future IPFS-Centric FDOs

dPIDs are an emerging PID technology based on decentralized architectures and self-sovereign identity [1]. dPIDs are PID containers, forming persistent storage systems where each object is identified by a unique PID. dPIDs are immune to content drift and resolves deterministically their mapped content, providing a reproducible binding between the (meta)data and identifier. As dPIDs take a decentralized net-work protocol approach to PIDs, their implementation of FDOF recommendations may require further explanation [2]. This presentation is a primer on the decentralized technologies behind dPID and their associated benefits, including a discussion of their potential usefulness for FDOs. dPIDs can form the fabric for a persistent, interoperable FDOs landscape. Data replication via the underlying content-addressed peer-to-peer network facilitates the implementation of FDO-G2 [3], ensuring long-term persistence and mitigating the risk of data loss via implicit data replication and storage redundancy between network participants. Content addressing gives dPID the property of deterministic and verifiable resolution, exceeding the requirements of FDO-PIDR2. A subsequent benefit of this open protocol-based approach is that dPIDs prevent the formation of vendor-lock-in and data silos, facilitating FDO-PIDR1 and FDO-G1. The provenance of data and updates to dPIDs are registered by digital signatures based on W3C de-centralized identifiers (DID), facilitating FDO-PIDR6. Data sovereignty is facilitated using a Directed Acyclic Graph (DAG) approach compliant with FDO-GR4, FDO-GR5 and FDO-GR6. DAGs also allow for granular machine actionability in compliance with FDO-GR1 and FDO-GR11. As PIDs are logged on Blockchain, tomb-stones for dPIDs are inherently permanent in line with FDO-GR12.
