The XRP Ledger network approved a new security proposal designed to stop flash loan attacks that have stolen hundreds of millions of dollars from cryptocurrency platforms over the past few years. A flash loan is a type of loan that gets borrowed and paid back within a single computer transaction, which lasts just seconds. Hackers exploit this speed to manipulate prices and drain money before anyone can stop them.
Flash loans exist because some cryptocurrency platforms allow users to borrow large amounts of digital money instantly without putting down collateral, or money held as insurance. The problem started around 2020 when attackers realized they could use this feature to trick the system into thinking they owned more money than they actually did. They would borrow millions, use that fake wealth to manipulate prices, and disappear with stolen coins before returning the loan.
Cryptocurrency traders and platform operators are directly affected by these attacks because they lose real money when hackers drain funds from the platforms they use. Small investors who store their crypto on affected platforms have also seen their savings disappear. The stolen money is often moved to other countries and converted into regular currency, making it nearly impossible to recover.
The XRP Ledger proposal adds new rules that make flash loans much harder to use for attacks. The network will track borrowed money more carefully and limit how fast attackers can move funds around. This change must be activated by the network's validators, which are computers that verify transactions, and experts expect this to happen over the next few weeks.
