Choice of serialisation format used for inter-node communication (RPC calls)

Requirements:

  • language-agnostic data representation
  • fast (enough)
  • can encode NodeIDs (256bit long integers)
    • fallback: either as string or as blob

Technologies to be considered:

  • JSON
    • needs string-representation of NodeIDs
  • ASN.1
    • standardised, established, but confusing
  • msgpack
    • binary serialisation format faster than JSON
    • supports blobs
    • has haskell RPC framework
  • Protocol Buffers
    • binary
    • support versioning
    • have a schema that could be imported by other implementers
