Rebar Labs 的目標是在 2024 年底前推出首個比特幣原生平台,保護交易者免受最大可提取價值 (MEV) 策略(例如搶先交易)的影響
Bitcoin ( BTC ) traders could soon have a new tool to protect themselves from harmful maximum extractable value (MEV) strategies, such as front-running.
比特幣(BTC)交易者很快就會擁有一種新工具來保護自己免受有害的最大可提取價值(MEV)策略的影響,例如搶先交易。
Rebar Labs, a company building Bitcoin-native decentralized finance (DeFi) infrastructure, is aiming to launch the first Bitcoin-native platform for shielding traders from MEV strategies by the end of 2024, CEO Alex Luce told Cointelegraph in an interview.
Rebar Labs 是一家建構比特幣原生去中心化金融(DeFi) 基礎設施的公司,執行長Alex Luce 在接受Cointelegraph 採訪時表示,該公司的目標是在2024 年底前推出第一個比特幣原生平台,以保護交易者免受MEV 策略的影響。
Bitcoin’s emerging ecosystem of native decentralized exchanges (DEXs) and layer-2 (L2) scaling solutions has reinvigorated the oldest blockchain network but has also created new risks for traders, including harmful MEV.
比特幣新興的原生去中心化交易所(DEX) 和第2 層(L2) 擴展解決方案生態系統重振了最古老的區塊鏈網絡,但也為交易者帶來了新的風險,包括有害的MEV。
“Right now, if we’re talking about MEV, the most obvious example on Bitcoin is front-running,” said Luce. “It’s happening fairly often.”
「現在,如果我們談論 MEV,比特幣最明顯的例子就是搶先交易,」盧斯說。 “這種事經常發生。”
MEV refers to the maximum profit that can be extracted from knowing the future state of the blockchain, typically used to describe strategies employed by miners to maximize their earnings. However, third parties can also use MEV to insert transactions into a block before others, enabling them to, for example, trade ahead of a large order and capture the profits.
MEV 是指透過了解區塊鏈的未來狀態可以獲得的最大利潤,通常用於描述礦工為最大化收益而採用的策略。然而,第三方也可以使用 MEV 在其他人之前將交易插入區塊中,例如,使他們能夠在大訂單之前進行交易並獲取利潤。
On Ethereum, where MEV strategies are more advanced, a group of builders called Flashbots has emerged to protect DEX traders from harmful MEV strategies, such as frontrunning and sandwich attacks, by bundling and sending out traders’ transactions anonymously.
在MEV 策略更為先進的以太坊上,出現了一群名為Flashbots 的建構者,透過匿名捆綁和發送交易者的交易來保護DEX 交易者免受有害的MEV 策略(例如搶先交易和三明治攻擊)的影響。
In turn, miners are incentivized to include these bundles, known as blocks, in the next chain by offering a portion of the MEV profits to the miners.
反過來,透過向礦工提供部分 MEV 利潤,激勵礦工將這些捆綁包(稱為區塊)包含在下一條鏈中。
According to Dune Analytics, Flashbots has protected around $43 billion of decentralized exchange trades from MEV since 2021. Rebar Labs’ Shield is set to become Bitcoin’s equivalent.
根據 Dune Analytics 的數據,自 2021 年以來,Flashbots 已經保護了約 430 億美元的去中心化交易所交易免受 MEV 的影響。
“We’re aiming to launch Shield with a sizable amount of the Bitcoin network’s hashrate,” said Luce. “We’re speaking with all the large miners in the space right now.”
「我們的目標是推出擁有大量比特幣網路算力的 Shield,」Luce 說。 “我們現在正在與該領域的所有大型礦商進行交談。”
According to Luce, good MEV on Bitcoin can help even out prices and aid traders in executing their trades quickly in a market where DEXs are largely interoperable and liquidity is fragmented.
Luce 表示,良好的比特幣 MEV 可以幫助平衡價格,並幫助交易者在 DEX 基本上可互通且流動性分散的市場中快速執行交易。
“On Bitcoin, these DEXs aren’t very interoperable, and liquidity is fragmented,” Luce said. “That’s where good MEV comes in — someone can come in, even out the prices, and help users with execution.”
「在比特幣上,這些去中心化交易所的互通性不是很好,流動性也很分散,」盧斯說。 “這就是優秀 MEV 的用武之地——有人可以介入,平衡價格,並幫助用戶執行。”
Moreover, Rebar’s Shield aims to enhance returns for Bitcoin BTC $68,468 miners, who process transactions and post them to Bitcoin’s blockchain ledger.
此外,Rebar's Shield 旨在提高比特幣 BTC 68,468 美元礦工的回報,這些礦工處理交易並將其發佈到比特幣的區塊鏈分類帳中。
Bitcoin began its journey as a simple peer-to-peer payment protocol, but its 2021 Taproot upgrade enabled the network to support more complex activities, such as creating and trading other types of tokens and minting non-fungible tokens (NFTs).
比特幣最初是作為一種簡單的點對點支付協議,但其 2021 年的 Taproot 升級使網路能夠支援更複雜的活動,例如創建和交易其他類型的代幣以及鑄造不可替代代幣 (NFT)。
However, Bitcoin-native DeFi is still nascent and is largely limited to crypto-native traders, as to use a Bitcoin DEX, traders must first interact on-chain to fund their trading accounts.
然而,比特幣原生 DeFi 仍處於萌芽階段,並且很大程度上僅限於加密貨幣原生交易者,因為要使用比特幣 DEX,交易者必須首先在鏈上進行交互,為其交易帳戶提供資金。
“Today, daily volume is in the millions, maximum. It’s not significant,” said Luce. “What we really view this space as right now is sort of a very early beta where you don’t have that many users interacting with it.”
「如今,每日交易量最多可達數百萬。這並不重要,」盧斯說。 “我們現在真正認為這個空間是一個非常早期的測試版,沒有那麼多用戶與之互動。”
“In the next 12 months, if you can’t get good execution on Bitcoin, chances are you’re going to move to an L2,” Luce added. “I think it’s a missed opportunity if that happens because Bitcoin is such a great market.”
「在接下來的 12 個月裡,如果你不能在比特幣上獲得良好的執行力,你很可能會轉向 L2,」Luce 補充道。 “我認為如果這種情況發生,那就錯失了機會,因為比特幣是一個非常好的市場。”
According to DefiLlama, the total value locked on Bitcoin’s L2s stands at approximately $2 billion as of Oct. 18. Some of the Bitcoin L2s include Babylon, Core Chain, Rootstock, and Stacks, among others.
據 DefiLlama 稱,截至 10 月 18 日,比特幣 L2 鎖定的總價值約為 20 億美元。
