Sino Amazons are deemed to have roamed the East Asia seas between about 1100 and 1700 AD. The Sinosignia is a unique character with an Asian appearance but is not a letter or a word. Each Sino Amazon has one unique to them, which they use as an identity in bonds and oaths.

The product comprises the Sinosignia which functions as a fully working Web3 Top Level Domain (TLD) off the Handshake Blockchain. It also provides an 'NFT type' digital image tokenized to a completely different chain.
