In XRP news today, David Schwartz, Ripple CTO Emeritus and co-founder of the XRP Ledger, has proposed a transaction reservation mechanism to prevent front-running and sandwich attacks on the protocol\u2019s decentralized exchange.<\/p>\n

The proposal arrives as community discussion around the XRP Ledger\u2019s payment infrastructure<\/a> intensifies, and coincides with active community voting on the XRPL 3.2.0 upgrade.<\/p>\n

Schwartz\u2019s proposal came with XRP USD trading at $1.04, down -0.2% on the day and dangerously close to losing the key technical and psychological support at $1, a level that, if lost, could see $0.80 revisited.<\/p>\n

Concerns have been raised about the possibility of front running or transaction sandwich attacks on XRPL payments and offer crossing.<\/p>\n

For the reasons I’ve explained, I’m not that concerned about this issue. But I have a proposal for a fairly simple scheme that would eliminate\u2026 https:\/\/t.co\/lnhTv1bhBK<\/a><\/p>\n

XRP News: What the TxnReserve Proposal Actually Does<\/h2>\n

The core mechanism introduces a new transaction type, TxnReserve, and a new ledger object,\u00a0ReservedTxns, which holds an array of transaction IDs assigned to a specific future ledger. To book a slot, a user pays at least twice the normal transaction fee and specifies a ledger sequence number and a transaction ID in advance.<\/p>\n

Reservations are capped at 32 slots per ledger and limited to the next 16 ledgers forward. Critically, the actual transaction is broadcast only after the previous ledger\u2019s consensus set is known, a timing window that denies would-be front-runners the visibility they need to act. Reserved transactions then execute first, in reservation order, before all other transactions in that ledger.<\/p>\n

Schwartz described the protection plainly: \u201cThis guarantees that you can execute your transaction ahead of any transaction that was formed after your transaction was disclosed. You would use this approach any time you want to perform a transaction that you want to ensure cannot be sandwiched or front run.\u201d<\/p>\n
