Blindly giving government agencies root TLS certificates because "ItS a SoVEReign NAtiOn" was one of the worse decisions every made in the entire history of CompSci. You can't change my mind.

I generally hate politicians and don't even like to hear their voices, but for some reason I like to watch those. (I don't know anything about this guy other than those videos, so don't make any assumptions other than the stated here)

I don't know if I should post this, but fuck. Here we go: I see all those people out in Venezuela, demanding the dictatorship to step down, but being violently repressed by the regime. Only one thing comes to mind: "if only they had guns..."

A picture I took 5 years ago of the sky. This was about 22h, southeast Brazil. Facing South-ish ~70 degree above the horizon. I've tried to find the original, but I only have this jpeg-ed version with lower quality :/ This was taken with a semi-professional camera (don't remember the model), 30s exposure.

This video is pretty cool

I can't believe how easy it was to make an lnaddress server with phoenixd, it works like magic!

My phone and laptop were searched for 3 hours by US CBP at a land border crossing. I tried to refuse and return to Canada but I was not allowed to...

Day after day I get less excited about visiting the USA

Someone just posted on the ML ``` I'd like to propose an idea of a simple logarithmic-size ring signature scheme which can be used in the blockchain and related applications. The signature is called LS-LSAG, a draft of it is available at

Simple Logarithmic-size LSAG signature

A number of existing cryptosystems use the well-known linear-size LSAG signature concept, extending it in many ways. This article presents a simple...

In making this announcement I'd like to ask the community to comment on the idea if anyone is interested. LS-LSAG has such a design so that it can drop-in replace the well-known linear-size LSAG/CLSAG signature. Also, it looks compatible with the full-chain Curve Trees, which in turn can drop-in replace both LS-LSAG and LSAG/CLSAG at the price of using one more curve with specific properties. In more detail, LS-LSAG is built up of almost the same systems of equations as LSAG/CLSAG. However, it makes a call to the inner-product argument instead of doing the sequential challenges. This results in the size reduction from linear to logarithmic and in the compatibility with LSAG/CLSAG. Particularly, LS-LSAG and LSAG has the same key image. Formally, LS-LSAG is a log-size linkable ring signature without trusted setup in a pairings-free prime-order group of EC points under the DL assumption. Unforgeability of LS-LSAG follows from the DL and collision-resistance of the standard hash-to-curve function, the draft contains a detailed proof sketch of this. ``` @waxwing did you see it?
