XCSS

"The first rarity ranking system based on SHA-256 cryptography."

Leveraging Bitcoin's SHA-256 cryptography, users can "mine" items and assign their rarity by brute-forcing specific transaction ID prefixes, similar to Bitcoin mining. The rarity increases exponentially with each additional digit in the prefix (e.g., '808', '8080', '80808'), demonstrating higher Proof of Work and longer mining efforts. XCSS is a groundbreaking NFT collection introducing a new rarity proof-of-concept.
