  • JSON-joy CRDT benchmarks, 100x speed improvement over state-of-the-art

    Love seeing CRDT innovation! I'm building something in the space, so excited to give this a try.

    The death stroke for these types of projects seems to be lack of funding. This project is sponsored by nlnet[0] providing between 5k - 50k EU per year. Let's hope this gets additional resources.

    As a note, it appears to use Elastic's 2.0 license preventing selling software that includes this library [1]
