Schwartz proposes XRPL anti-front-running fix

• Ripple (CRYPTO:XRP) Chief Technology Officer David Schwartz proposed a transaction reservation system to reduce front-running risks on the XRP Ledger.
• The proposal follows claims that some network participants may view pending transactions before ledger closure and use that information to gain trading advantages.
• The discussion comes as XRPL expands its decentralised finance capabilities, increasing the importance of fair transaction ordering.

Ripple (CRYPTO:XRP) Chief Technology Officer David Schwartz proposed a transaction reservation mechanism for the XRP Ledger (XRPL) that would allow protected transactions to execute before later-submitted transactions in the same ledger.

The proposal follows claims by XRPresso that validators and well-connected nodes may be able to view pending transactions before a ledger closes, potentially allowing some participants to target trades through front-running strategies.

“For the reasons I’ve explained, I’m not that concerned about this issue,” said David Schwartz.

Schwartz proposed creating a new ReservedTxns ledger object and a TxnReserve transaction type, allowing users to reserve execution slots up to 16 ledgers in advance, with reservation fees set at least twice the standard transaction fee and each reservation initially limited to fewer than 32 transaction IDs.

The proposal has not yet been submitted as a formal XRPL amendment, and there was no immediate market reaction following its publication.

The discussion comes as XRPL developers continue expanding the network's decentralised finance infrastructure through proposed upgrades including AMM Swappable Curves, native lending and programmable escrow functionality.

As institutional and decentralised finance activity grows on XRPL, including tokenised asset settlement and automated market maker services, transaction ordering and protection against front-running are expected to become increasingly important for users, developers and validators.

At the time of reporting, XRP price was $1.05.
