Thinking of the incident where Bybit was hacked for 1.4 billion dollars. Not to mention, those responsible for the wallet technology at Bybit must be incompetent.

Or rather, the exchange emphasizes operations, and most services are appropriationist, not developed in-house, and no preventive measures are taken.

What I find particularly ironic is that we spent all that time researching MPC and multi-signature wallets, with numerous measures to prevent cryptocurrency theft.

Had we used just one of those measures, we could have avoided that 1.4 billion dollar loss.

The simplest measure is that we would decompile the signature results to check if the signature is correct. Then we would take the signature data out of the closed vault and broadcast it to the network.

This mechanism guarantees 100% security. It could have also prevented the Bybit incident.

These achievements amazed the Japanese, who applauded every day.

Unfortunately, despite this, neither our wallet nor our team was appreciated, mainly because we only focused on research and had no way to commercialize.

Just two or three of us developed it thoroughly over two years. Compared to Bybit's CTO, who has tens of millions of dollars in resources, we had almost nothing, yet we were much stronger than them.

However, this was of no use; I later resigned. That product ended up in the app graveyard.

The key MPC multi-signature code was developed by a Russian guy.

Now I don't know where it went. Good things are buried in the app graveyard.
