Invariants of block cipher round functions and definability

In this post, we shall discuss a problem with measuring the cryptographic security of a block cipher round function along with a solution to this problem that works for block ciphers like the AES. For this post, the reader is supposed to understand the basics of model theory, some group theory, universal algebra, and cryptographyContinue reading “Invariants of block cipher round functions and definability”

Do the round maps of your block cipher generate the alternating or symmetric group?

This is the first post in a series of posts about block ciphers. From now on, I will try to produce more technical posts that involve more mathematics. This series of posts will be about symmetric encryption and related algorithms, but I do not have any plans in the immediate future of posting about publicContinue reading “Do the round maps of your block cipher generate the alternating or symmetric group?”

Buy Circcash slowly.

Circcash currently has a quite low market capitalization. Hopefully the market capitalization of Circcash would increase soon, and since Circcash is the only cryptocurrency with a mining algorithm that is designed to solve an extremely important scientific problem, we should regard Circcash as a very valuable digital currency whose value will increase over time asContinue reading “Buy Circcash slowly.”

I will not predict the future price of assets for you.

Most of the content of this post is rather basic, but I still need to clear up some basic misconceptions and pitfalls regarding whether one should invest in something such as Circcash. Please do not ask me how much do I think that Circcash or Bitcoin or anything else will be in 1 year orContinue reading “I will not predict the future price of assets for you.”

At this point, mining pools are unnecessary and a point of insecurity.

(update: 7/25/2021. Solo mining on the Circcash-qt wallet is not longer applicable since Circcash is now GPU minable.) On March 4, 2021, the price of 1 CIRC according to the Bitsails exchange is about 1 cent. This means that the value of 1 block is 10 cents. From March 2,2021 to March 9,2021 the priceContinue reading “At this point, mining pools are unnecessary and a point of insecurity.”

Circcash does not need to be put on multiple exchanges yet.

This post was written on 1/31/2021. The status of Circcash can change quickly due to many reasons, and the points in this post may or may not apply to future dates. Right now, Circcash is listed on the Bitsails cryptocurrency exchange. Circcash is not listed on any other exchange, and Circcash can only be tradedContinue reading “Circcash does not need to be put on multiple exchanges yet.”
