[ANN] Circcash has been launched

[jvanname]

I am pleased to announce the relatively new cryptocurrency called Circcash. Circcash keeps all of the good features of the decentralized digital currencies Bitcoin and Litecoin, but Circcash mining is designed to solve one of the most important scientific problems, the problem of reversible computation.

Reversible computation is the type of computation where one deletes little to no information. Landauer's principle states that every bit of information deleted costs more than k*T*ln(2) energy where k is Boltzmann's constant (k=1.38*10^(-23)Joules/Kelvin), T is the temperature, and ln(2)=0.693... This is not a lot of energy at CPU temperatures, but the energy efficiency of transistors is getting to the point where one needs to take the k*T*ln(2) limit very seriously (all forms of irreversible computation start to have problems well before k*T*ln(2) since it takes energy to overcome thermal noise). Remember that heat production and energy efficiency are the main limiting factors to the performance of integrated circuits, so if we can improve energy efficiency and reduce the amount of waste heat produced, then we will obtain an increase in performance as well. Reversible computation bypasses the k*T*ln(2) per bit deleted limit because reversible computation does not delete very much information. Reversible computation can therefore be much more energy efficient and powerful than conventional computation.

Recent research by Ralph Merkle indicates that reversible computation can be several orders of magnitude more energy efficient than Landauer's limit k*T*ln(2) while operating at a frequency of 100 MHz [1]. At this frequency, this translates to about an energy efficiency of about 10^(21) FLOPS/Watt or about 10^(-27) J per rotation per rotary joint (this is about a million times smaller than Landauer's limit k*T*ln(2)). This is millions of times better than anything that is possible with irreversible computation. There are plenty of other possible ways that one could also make reversible computing hardware besides those based on Ralph Merkle's papers (for example, quantum computation can be thought of as an enhanced version of reversible computation). We should therefore expect for reversible computers to eventually outperform all conventional computers.

There is a problem however. Computing without deleting much information is a little bit tricky since one will need to use new algorithms, programming languages, and hardware, and even once all these problems are solved, reversible computation will require more memory and operations. Research by Charles Bennett [2] shows that anything that can be computed by a conventional computer can also be computed by a reversible computer with a modest increase in the space requirements and the number of operations. Since the increase in the computational complexity of the computation is modest, we should expect for reversible computation to outperform conventional computation on all tasks in the far future, but we should also expect for it to be extremely difficult to manufacture practical reversible computers in the near future. This is where Circcash becomes extremely useful.

Circcash's mining algorithm, Hashspin, is designed to use very simple hardware and to run 99.9% of all operations reversibly. Since Circcash's mining algorithm is almost completely reversible, it will be much easier to produce reversible ASICs for mining Circcash than to produce reversible computers for any other purpose. Furthermore, since Hashspin only requires very simply hardware, it will most likely be much easier to mass produce profitable reversible hardware for mining Circcash than it would be to mass produce profitable reversible computing hardware for any purpose. Circcash will therefore enable the hardware manufacturers to make a profit from reversible computational hardware much earlier and much more easily than if Circcash did not exist.

Circcash is the only cryptocurrency with a mining algorithm that is designed to solve an extremely important scientific problem that will continue to revolutionize computation.

From these facts, you should conclude that Circcash is currently an extremely good deal. There is absolutely no reason not to invest in Circcash.
