No, I am not the original 0xbitcoin developer. I believe the reference person for 0xbitcoin is infernal_toast, whom I greatly respect for his work.

I only made some minor modifications and settings to the 0xbtc contract to make it compatible with the Binance Smart Chain (BEP-20) and to restore some original Nakamoto's design features. We announced it yesterday: for more details you can visit https://bnbitcoin.org.

I know that they published some works on their repos on GitHub about L2 scaling... let's see what happens...

Thank you!
