Design Flaw in Cryptocurrency
Cryptocurrencies, like all computer systems, can have design flaws. These flaws may be related to the underlying code or architecture of a cryptocurrency and can result in security vulnerabilities that could allow attackers to gain access to users’ funds or otherwise disrupt normal operations of the system. Design flaws can also lead to unintended consequences when changes are made without taking into account their potential impact on other parts of the system.

In some cases this resulted in double spending where two different transactions had identical information but one would succeed while another would fail due
