 Hi $kas, its about time we had a long hard talk about ASICs. There is a lot to say, which I will in a future Medium post, but for now I want to drop some key takeaways ๐Ÿงต 1/n
 1. ASICs are the end game of any POW coin: designated hardware always wins eventually, and trying to use "ASIC resistance" is just delaying the inevitable.

 Protecting cryptocurrency procrastinators in the quantum era, a ๐Ÿงต about a newly published preprint by @or_sattath and myself.

 Part 1: the problem.

Bitcoin and most other cryptocurrencies rely on ECDSA/EC-Schnorr signatures for security. These signature schemes are famously quantum compromised: a relatively small quantum computer can compute the secret-key from the public key.

Speed does matter!

A common criticism about $kas is that "speed doesn't matter". In this ๐Ÿงต I hope to convince you that speed is not just a nice feature to have, but absolutely essential for the long term sustainability of a decentralized proof of work chain. 1/n
But before we begin, what actually *is* speed? People use this term interchangeably to mean three different things: BPS, TPS and confirmation times.

Confirmation times are more subtle than people realize. They are crucial for usefulness and poor confirmation times are a

1/n On November 1st, the #dagknight protocol will finally be revealed in SECS22 Berkeley (cesc.io). I think it is only appropriate to take the time to explain what makes DAGknight so exciting, and what it means for PoW in general and $kas in particular. ๐Ÿงต Image 2/n First, a clarification: DAGKnight is the brainchild of @MichaelSuttonIL with the advisory of @hashdag. The basis for DAGKnight are ideas Michael and myself came up with to solve the pruning problem in DAGs (Medium post pending) but I was never directly involved with DAGKnight
