Which country uses ZiG?

Could you please clarify which country specifically utilizes the term 'ZiG' in relation to cryptocurrency or finance? I'm intrigued by the mention of 'ZiG' and its potential use in these fields, but I'm not familiar with any widely recognized country that has adopted it as a standard or term of reference. Are there any particular regions or markets where 'ZiG' holds significance, or is it perhaps a misspelling or reference to a specific technology or protocol within the cryptocurrency ecosystem? I'd appreciate any insight you can provide to help me better understand the context and significance of 'ZiG' in the world of cryptocurrency and finance.
