FACT-CHECK ALWAYS
Rumors of $XRP becoming a gold-backed currency has been circulating in social media, insinuating the price then will be as high as the GOLD OZ (~3300/oz), albeit Ripple former members publicly deemed it as a plan incompatible with descentralized transaction, although Ripple is to pronounce official to deny such claims.
Gold tokenization on the XRP Ledger and the Network itself are separate entities.
For tokenized commodities,you have PAXOS Gold ($PAXG ), which is a gold back TOKEN.
