Team XDNA presents a novel hashing algorithm - HEX !
The creation of every block using HEX launches 16 pseudorandom sequences of 16 algorithms (kernels). The employed kernels are:
BLAKE
BMW
GROESTL
JH
KECCAK
SKEIN
LUFFA
CUBEHASH
SHAVITE
SIMD
ECHO
HAMSI
FUGUE
SHABAL
WHIRLPOOL
SHA2.
How it works:
The first hexadecimal position from the previous block points to one of the listed kernels, and the corresponding hash is calculated.
The result of the hashing procedure is subjected to another hash computation using a different kernel.
The calculations go on until a sequence of calculations using all 16 kernels is done. The first kernel is constant for a specific block, but the rest of the sequence is impossible to predict.
The kernel sequence operation is further repeated 15 more times. Only the result of the final hashing is validated. For the following block the process starts from scratch.
The HEX algorithm possesses a number of pronounced benefits compared to the majority of existing algorithms:
- it is not a “dummy” algo like the some other algos, when the GPU spends a lot of time awaiting commands and not performing computations;
- it exhibits a stable and uniform GPU load and thus provides for better efficiency of the equipment;
- constant and unpredictable variation of the kernels presents a pain for the adaptation of FPGAs and ASICs to it.
XDNA team have performed complex mathematical modeling and adjusted the BitGun levels accordingly to the difference in typical GPU productivity for keccak and HEX.
XDNA value the opinion of the crypto community. Feedback with a lot of concern for coin hyper-emission on the highest BitGun levels has led us to redesign the block rewards for different levels. Team has significantly lowered the rewards for the levels above 11 and slightly increased the rewards for levels 4-9.
Calculation results for HEX
Regardless of these changes, every miner will still receive much greater rewards compared to the classical reward system.
Now XDNA has THREE TRUE innovations!
