The blockchain realm is considered to be one of the most promising inventions. However, in blockchain<\/a>, the prevalence of Double-Spending is believed to be a major source of concern. Double spending in blockchain basically occurs when a party attempts to utilize the same digital funds more than once.<\/p>\n

If multiple transactions share the same input, it can get really problematic. In fact, blockchain is specifically designed to prevent such practices from taking place. The double spending problem blockchain is a unique flaw that has come into existence in the context of digital currencies. The fundamental reason for the problem is that it is very simple and easy to reproduce digital currency.<\/p>\n
