Techub News reports that the Korea Financial Services Commission (FSC) has required all cryptocurrency exchanges in South Korea to establish a system by the end of May that checks and verifies their internal ledgers against actual cryptocurrency holdings every five minutes. According to the FSC, three of the country's five major cryptocurrency exchanges perform asset reconciliation once every 24 hours, while the remaining two conduct internal ledger versus actual holdings checks every 5 to 10 minutes. Additionally, the FSC pointed out that their trading suspension system (also known as the shutdown switch) was found to have some flaws in the event of large-scale asset mismatches.
