Purpose of this thread is to announce Circcash cryptocurrency to the public and to allow uncensored discussion about Circcash related topics.
This is unofficial thread and will remain un-moderated.
UPDATE (Nov 21):
Here is an official Circcash announcement:
https://bitcointalk.org/index.php?topic=5292018.0;all
What is Circcash? Circcash is a fork of Bitcoin using Hashspin as a proof-of-work algorithm. Hashspin is designed to accelerate the development of reversible computing hardware. Hashspin is the only cryptocurrency mining algorithm that is designed to solve an extremely important scientific problem.
- 2.0 minute block targets
- 10 CIRCs per block
- No subsidy halving
- Supply increases linearly (to better advance science)
- Mining reward remains constant
- 2016 blocks to retarget difficulty
- 12.5% of newly mined coins will be sent to a development fund. The development fund will be cut off after the following two conditions are BOTH met:
1. The cryptocurrency has been out for four years, and
2. The total number of 'hashes' computed for mining exceeds a threshold.
- Forked from Litecoin v0.8.7.5
The Circcash development team may cut off the 12.5% funding early.
The rest is the same as Bitcoin/Litecoin.
. . .
Note the whitepaper still uses the old name "Zammazazzer". The name of the cryptocurrency has been updated from Zammazazzer to Circcash.
The proposed cryptocurrency Zammazazzer is designed to incentivize
the development of the reversible computer. Reversible computers will
eventually outperform and replace conventional computers everywhere. By
Landauer’s principle, reversible computers will eventually become many times
more energy efficient than the possible the maximum possible efficiency of an
irreversible computer. Since reversible computers will do calculations without
producing the immense amount of heat required by conventional computers,
reversible computers can potentially run many times faster than conventional
computers with much denser parallelism. However, while reversible computers
will eventually replace conventional computers, these energy efficient reversible
computers do not exist in the free market, and hardware manufacturers are
unwilling to make reversible computers in part due to the computational overhead
incurred from using reversible algorithms instead of conventional algorithms.
The proof-of-work problem for Zammazazzer is designed to incentivize the
initial development of the energy efficient reversible computer, and the
Zammazazzer Foundation, supported through cryptocurrency coins, shall fund
the research, development, and standardization of cryptographic algorithms
suitable for reversible computers through the use of smart contracts.
[...]
Each coin shall be called a CIRC which stands for Certificate of Innovation in Reversible Computation.
