To understand how PoW NFT chess became possible its need to understand what hacash is.
Hacash has 3-coins ecosystem:
$HAC - base currency, mining every block, (X16RS)
$HACD - mining every 5 blocks, but to get it - miners bid $HAC, and the highest bid is burning, and miner receives $HACD.
more $HAC - more burns - less $HAC
$HACD as an asset is unique PoW multi NFT, it has a 6 letter-name, visual gene and life gene. By visual gene it already has 3 visualisations: HIP-5, HIP-8, HIP-9.
and third layer is $BTC on hacash chain.
https://hacdchess.online uses your HACD, to visualise it as initial chess position, which you can play against others.
