Some remarks:

    - Seems to be implemented in C++
    - Looks like they reused bits and pieces from the Bitcoin code base (bech32, secp256k1, sha256)
    - Claim of being able to handle 1.7M TPS
    - Experimented with UTXO-style (Bitcoin-like) but seem to have bet on something called "unspent hashes" instead.
    - I found very little on things that matter (policy-related):
       - How is the "central authority" implemented
       - How is the coin supply managed
