Ripple (CRYPTO: XRP) Chief Technology Officer David Schwartz on Monday proposed a new transaction reservation scheme to eliminate front-running and sandwich attacks on the XRP Ledger.
How Validators Currently Game The System
XRPresso explained the issue in a viral thread on Monday. The problem is that some well-connected XRP Ledger validators may be able to see trades just before they are finalized.
That gives them a small but powerful advantage. If they spot a large trade coming, they can place their own trade right before it and another one right after it. This can move the price against the original trader, while the validator profits from the gap.
Normal users trading through regular wallets or apps cannot see this happening in advance. They simply get a worse price, while validators with faster access or better visibility keep gaining an edge.
