I'm starting to wrap up Safecat for publishing its next version. The highlight there is Woolball server integration.

So far you could have created certificates for other people, but it required a cumbersome exchange of private keys and certificates.

Now? it is all automated with a name system (and a server, oh boy).

I also want to create an installation package (for Linux).

Here's the relevant branch. Don't run it yet! The server is still not activated.

Marius Van Der Wijden claims to have broken Iden3's implementation of the Poseidon Hash. It is quite well-known, and probably used, so it's quite interesting.

He claims the problem is with their bit padding.

Normally you add '1' and then zeroes (possibly none) to fill the block length. This ensures that there is always *some* padding.

They didn't add the '1', so some input doesn't get padded at all, which leads to a collision.

I published "Duopsism" during the holiday season, when no one was here. Here is it again.

Duopsism: A person is sitting in a dark room. There's nothing there besides a programmable black box.

What can the person deduct about himself? the world?

A whimsical thought experiment in the spirit of Descartes and Mary's Room.
