On October 23rd, the International Association of Coders (ANNA) established a working group to address the issue of standardization of digital asset tags across the financial markets. ANNA today announced that the new working group will consider the appropriate International Securities Identification Number (ISIN), which is used by the International Organization for Standardization (ISO) to promote global enterprise standardization. The association said the group will investigate digital asset tags for cryptocurrency, tokens and blockchain technologies that intersect with financial markets. It is reported that although most cryptographic exchanges use a standardized set of codes, if traditional financial exchanges ultimately deal with digital assets, some differences need to be overcome. For example, Bitcoin has traditionally been called BTC, but XBT has also been used recently because it is similar to the gold stock code XAU.
