| description | The ongoing regulation of blockchain-based services and applications requires
the identification of users who are issuing transactions on the blockchain.
This systematic review explores the current status, identifies research gaps,
and outlines future research directions for establishing trusted and
privacy-compliant identities on the blockchain (on-chain identity). A
systematic search term was applied across various scientific databases,
collecting 2232 potentially relevant research papers. These papers were
narrowed down in two methodologically executed steps to 98 and finally to 13
relevant sources. The relevant articles were then systematically analyzed based
on a set of screening questions. The results of the selected studies have
provided insightful findings on the mechanisms of on-chain identities. On-chain
identities are established using zero-knowledge proofs, public key
infrastructure/certificates, and web of trust approaches. The technologies and
architectures used by the authors are also highlighted. Trust has emerged as a
key research gap, manifesting in two ways: firstly, a gap in how to trust the
digital identity representation of a physical human; secondly, a gap in how to
trust identity providers that issue identity confirmations on-chain. Potential
future research avenues are suggested to help fill the current gaps in
establishing trust and on-chain identities. |
