Solana 重量級人物向私人 Mempool 業者發動戰爭

被發現協助三明治攻擊的驗證者將面臨嚴厲的處罰。

A group of Solana (SOL) validators are facing financial penalties for allegedly facilitating economic attacks against crypto traders.

一群 Solana (SOL) 驗證者因涉嫌協助針對加密貨幣交易者的經濟攻擊而面臨經濟處罰。

Over 30 validator operators were kicked off the Solana Foundation Delegation Program over the weekend, a source familiar with the matter told CoinDesk. While they remain validators on the network, they're no longer eligible to receive what amounted to payout boosters for validating transactions on the Solana blockchain. Many of the operators were Russians, another source said.

一位知情人士告訴 CoinDesk，週末有超過 30 個驗證器運營商被踢出 Solana 基金會授權計劃。雖然他們仍然是網路上的驗證者，但他們不再有資格獲得用於驗證 Solana 區塊鏈上交易的支付獎勵。另一位消息人士稱，許多操作員都是俄羅斯人。

The purge escalates a months-long shadow war between heavyweights of the Solana validator ecosystem and an underground economy of validators believed to be exploiting traders for profit through what's known as a "sandwich attack," whereby bots frontrun and backfill trades that haven't yet been executed.

這次清除加劇了Solana 驗證器生態系統的重量級人物與驗證者的地下經濟之間長達數月的影子戰爭，這些驗證者被認為通過所謂的“三明治攻擊”剝削交易者以獲取利潤，即機器人搶先交易並回填尚未完成的交易。

It's among the more notorious maximal extractable value, or MEV, strategies possible on blockchains that rely on mempools, which are essentially waiting rooms for unconfirmed transactions. Solana doesn't have a native mempool, but the wildly popular validator software developed by Jito Labs once did.

它是依賴內存池的區塊鏈上最臭名昭著的最大可提取價值（MEV）策略之一，內存池本質上是未經確認交易的等候室。 Solana 沒有原生記憶體池，但 Jito Labs 開發的廣受歡迎的驗證器軟體曾經有。

In March, at the height of Solana's meme coin frenzy, Jito Labs shut off the mempool function because it was exposing traders to near-constant and costly sandwich attacks. Jito's CEO framed the move as being in the best interest of the Solana ecosystem even if it cut off one potential revenue stream for validators, the server operators who keep things running on this decentralized network.

今年 3 月，在 Solana 的 meme coin 狂熱達到頂峰時，Jito Labs 關閉了 mempool 功能，因為它使交易者面臨近乎持續且代價高昂的三明治攻擊。 Jito 的執行長認為此舉符合 Solana 生態系統的最佳利益，即使它切斷了驗證者（維持這個去中心化網路運作的伺服器營運商）的一個潛在收入來源。

Rather than completely solve the problem, Jito's move pushed it underground. Whispers quickly emerged of private mempools whose operators were making at times hundreds of thousands of dollars by enabling sandwich attacks.

Jito的舉動非但沒有徹底解決問題，反而將其推入地下。私人內存池很快就出現了謠言，這些內存池的運營商有時通過發起三明治攻擊賺取數十萬美元。

One proposal from infrastructure operator DeezNode offered validators who opted into its private mempool 50% of the profits generated by MEV, according to documents reviewed by CoinDesk.

根據 CoinDesk 查閱的文件，基礎設施營運商 DeezNode 的一項提案向選擇加入其私人記憶體池的驗證者提供 MEV 所產生利潤的 50%。

A Jito Foundation governance post from late Sunday indicates 10% of the JitoSOL pool is being delegated to validators running private mempools. The Jito Foundation has proposed imposing further economic penalties on those validators by way of restricting yet more staked SOL.

Jito 基金會週日晚間的一篇治理貼文表明，JitoSOL 池的 10% 被委託給運行私有記憶體池的驗證者。 Jito 基金會提議透過限制更多質押 SOL 的方式對這些驗證者實施進一步的經濟處罰。

Solana Foundation's own delegation blacklist is small as a portion of the delegation program. It targets a total of 32 operators that together had 1.5 million SOL, about 0.5% of program stake, a source said.

Solana 基金會自己的委託黑名單作為委託計畫的一部分很小。消息人士稱，其目標總共 32 家營運商，總共擁有 150 萬枚 SOL，約佔該計畫股份的 0.5%。

"Enforcement actions are on going as we detect operators participating in mempools which allow sandwich attacks," a representative for the Solana Foundation said Sunday.

Solana 基金會的一名代表週日表示：“當我們檢測到參與允許三明治攻擊的內存池的運營商時，執法行動正在進行中。”
