Blockchain interoperability conflates the need for blockchains to communicate with third-party systems and other distributed ledgers via interoperability mechanisms (IMs). Blockchains increasingly rely on exchanging data and value across network boundaries in a more mature and interconnected set of ecosystems. However, interoperability comes with challenges. Through a systematic literature review, we identified the main challenges impacting the field: 1) the lack of a common conceptual model for blockchain interoperability, and thus a lack of evaluation frameworks for IMs; 2) the absence of organizational interoperability in most IMs; and 3) ineffective methods for blockchain interoperability security.

Corruption is a major problem worldwide. It comes in the form of dishonesty or criminal offense when parties entrusted with a position of authority, acquire illicit benefit – affecting all areas of society. It then does not come with a surprise that corruption is present at governments, given a variety of reasons: technological limitations regarding traceability, lack of transparency, lack of auditability, and lack of accountability. This causes distrust among stakeholders within the government, causing prejudice to possible synergies that can raise efficiency and improve the status quo.
