Chartifact basics

[jMyles]

• Secret goes on chart
• Metadata about chart (and relationship to song, and to artists, etc) goes on chain
• Possible 'default' mode (for another issue)
• Once chart is sold, clock starts ticking
• At 1-year and 5-year mark, automatic auction starting at 5x official sale price
• Chartifacts are compatible with embedded player (also another issue / many issues)
