Awesome! You really nailed it.

CBOR is a schema-less binary format. JSON BinPack supports both schema-less (like CBOR) and schema-driven (with JSON Schema) modes. Even on the schema-less mode, JSON BinPack is more space-efficient than CBOR. See https://benchmark.sourcemeta.com for a live benchmark and https://arxiv.org/abs/2211.12799 for a more detailed academic benchmark
Thanks for linking the benchmarks. I appreciate the work on shaving additional bytes especially in cases where every byte matters. Real savings seem to be in the schema-driven mode. Comparing a "realistic", schemaless payload for a general storage use-case (eg. the config examples), it looks pretty even with CBOR. E: my bad, BinPack is getting more efficient with larger payloads https://benchmark.sourcemeta.com/#jsonresume

Very cool! How are the balloons transferring telemetry back to earth for analysis, etc?
Asking because my research at the University of Oxford was around hyper space-efficient data transfer from remote locations for a fraction of the price.
The result was an award-winning technology (https://jsonbinpack.sourcemeta.com) to serialise plain JSON that was proven to be more space-efficient than every tested alternative (including Protocol Buffers, Apache Avro, ASN.1, etc) in every tested case (https://arxiv.org/abs/2211.12799).
If it's interesting, I'd love to connect and discuss (jv@jviotti.com) how at least the open-source offering could help.
Sounds cool. How does it differ from CBOR?
