This story shows why blockchain is a financial time bomb. Why? The underlying assumption of infallibility reflected in statements like "user will always be safe" and "the data is immutable and true."
History has shown that no system is immune to fraud, crime, and abuse, and pretending that this time it will be different can only lead to financial ruin for individuals and institutions.
The current financial system is bad enough but at least there is a communal understand that it's flawed. Blockchain by is being built on a foundation of false hopes and fairy dust.
