Summary:In recent years, multiple distributed ledger technologies with different strengths and weaknesses have been introduced. This makes them better suited for different use cases, but it also makes interactions between the ledgers more difficult. Interledger technologies try to bridge this gap, but often suffer from obvious limitations: a large portion of the solutions addresses only value exchanges or transfers, others have restrictive assumptions about the ledgers, and some require separate relaying blockchains. This paper introduces the Flexible Interledger Bridge (FIB) design that supports a wide range of use cases and ledger types without requiring any changes to the ledgers themselves. An evaluation of the reference implementation shows it to be a lightweight solution that enables atomic data transfers between two ledgers.
