~20% of Bitcoin's supply could be stolen by a quantum computer tomorrow. This week we hosted Prof. @or_sattath and Dr. @DesheShai in Tel Aviv to break down what's actually at risk, what's already in flight, and what blockchain looks like after a post-quantum migration. Recap 👇

Sorry for another extremely graphic post, but I feel obliged to share as people still don't understand what transpired. The descriptions will almost surely disturb you, keep that in mind if you want choose to keep reading. The sister of a friend of a friend was one of the people

Ladies and gentleman of $kas and crypto, I don't think you understand the magnitude of what's going on right now. We are witnessing, for the first time in history, a fully deployed production mainnet of a PoW coin perfectly handling a constant organic throughput of 250-300 BPS,

It took Israel more than a week to figure out the death toll of 7/10, and the number is still not finalized. Gazan authorities, somehow, manage to come up with death tolls within minutes. Magic.

Kaspa $kas is poorly communicated. That's a fact. Let's tend to it, together. Kaspa is very well branded and marketed. Everyone's heard about it and is aware of its visual language and color scheme. But still, it is poorly communicated. If you look Kaspa up on YouTube, you
