David Schwartz, former CTO of Ripple and one of the core developers of the XRP Ledger (XRPL), shared a proposal for introducing a transaction reservation scheme. This comes as some raised concerns over front-running and sandwich attacks on the network’s decentralized exchange and automated market makers.
Ex-Ripple CTO David Schwartz Shares Fix for Front-Running Attacks on XRP Ledger
XRP community members raised concerns about how validators and well-connected nodes can view transactions in the pre-validation queue. This allows them to analyze pending trades, determine profitability, and spam multiple transactions to make favorable positions on XRP Ledger (XRPL).
While XRPL executes transactions in mixed orders to discourage front-running, some claimed the protection is not sufficient. Users executing trades on decentralized exchange (DEX) or automated market makers (AMMs) could suffer slippage from sandwich attacks.
Ex-Ripple CTO David Schwartz said “I’m not that concerned about this issue. But I have a proposal for a fairly simple scheme that would eliminate this attack.”
He proposed a transaction reservation scheme designed to ensure transactions execute before they get disclosed on-chain. ReservedTxns, a new ledger object, will hold an array of transaction IDs for a specific future ledger.
In addition, ex-Ripple CTO introduced a new transaction type, TxnReserve, which users submit to book a slot by paying at least double the normal transaction fee. Reservations are limited to the next 16 ledgers and capped at 32 slots per ledger to maintain efficiency.
Ripple CTO David Schwartz Explains How the Reserved Transactions Will Work
Ex-Ripple CTO David Schwartz said once a slot is reserved, the transaction is broadcast only after the previous ledger’s consensus set is known. This prevents front-running attacks. Reserved transactions then execute first in the order they were reserved, before other transactions in that ledger.
Schwartz added that transaction success depends on various factors. This includes a double fee than the normal transaction fee and normal transaction execution requirements.
Moreover, it has built-in denial of service (DoS) protection. “This is mitigated by the fact that they would have to pay continuously and others could simply wait the attack out, Ripple CTO David Schwartz added.
XRP Price amid XRP Ledger Upgrade Voting
XRP price continues to move in the $1.03-$1.05 range in the past 24 hours. Furthermore, trading volume has increased by 25% over the last 24 hours, indicating a rise in interest among traders as the US and Iran suspend strikes.
CoinGlass data showed buying in the derivatives market. Total XRP futures open interest jumped 0.80% to $2.36 billion in the last 4 hours. XRP futures OI on CME and Binance climbed more than 0.75% and 1.36% amid XRP Ledger 3.2.0 upgrade.
Analyst Crypto Tony shared a weekly chart for XRP price. He pointed out that the price is moving near inflection points and risks a potential 30% drop below the current level.
