Since there has as of yet been no detail discussed regarding the SOLAR and LUNAR currency algorithms,  I propose that we consider using the Cryptonight Heavy algorithm.  The advantages to this are:

1.  Currency is truly private and fungible (all coins are equal and there is no transaction history built into the coins themselves, making them true privacy coins).  See MONERO and RYO as examples.

2.  Cryptonight Heavy is ASIC resistant, meaning that developing dedicated hardware to speed the mining (and corner the market) is always a step behind the curve and thus unusable.

3.  Cryptonight Heavy can be run on relatively midrange hardware, including CPUs and GPU's from several years back, making it an easy entry level coin that many Asgardians could support in terms of hardware.
