Rebar Labs 的目标是在 2024 年底前推出首个比特币原生平台,保护交易者免受最大可提取价值 (MEV) 策略(例如抢先交易)的影响
Bitcoin ( BTC ) traders could soon have a new tool to protect themselves from harmful maximum extractable value (MEV) strategies, such as front-running.
比特币(BTC)交易者很快就会拥有一种新工具来保护自己免受有害的最大可提取价值(MEV)策略的影响,例如抢先交易。
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 是一家构建比特币原生去中心化金融 (DeFi) 基础设施的公司,首席执行官 Alex Luce 在接受 Cointelegraph 采访时表示,该公司的目标是在 2024 年底前推出第一个比特币原生平台,以保护交易者免受 MEV 策略的影响。
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.
比特币新兴的原生去中心化交易所 (DEX) 和第 2 层 (L2) 扩展解决方案生态系统重振了最古老的区块链网络,但也给交易者带来了新的风险,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.”
“现在,如果我们谈论 MEV,比特币最明显的例子就是抢先交易,”卢斯说。 “这种事经常发生。”
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 是指通过了解区块链的未来状态可以获取的最大利润,通常用于描述矿工为最大化收益而采用的策略。然而,第三方也可以使用 MEV 在其他人之前将交易插入到区块中,例如,使他们能够在大订单之前进行交易并获取利润。
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 策略更为先进的以太坊上,出现了一群名为 Flashbots 的构建者,通过匿名捆绑和发送交易者的交易来保护 DEX 交易者免受有害的 MEV 策略(例如抢先交易和三明治攻击)的影响。
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.
反过来,通过向矿工提供部分 MEV 利润,激励矿工将这些捆绑包(称为区块)包含在下一条链中。
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.
根据 Dune Analytics 的数据,自 2021 年以来,Flashbots 已经保护了约 430 亿美元的去中心化交易所交易免受 MEV 的影响。Rebar Labs 的 Shield 将成为比特币的等价物。
“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.”
“我们的目标是推出拥有大量比特币网络算力的 Shield,”Luce 说。 “我们现在正在与该领域的所有大型矿商进行交谈。”
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,良好的比特币 MEV 可以帮助平衡价格,并帮助交易者在 DEX 基本上可互操作且流动性分散的市场中快速执行交易。
“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.”
“在比特币上,这些去中心化交易所的互操作性不是很好,流动性也很分散,”卢斯说。 “这就是优秀 MEV 的用武之地——有人可以介入,平衡价格,并帮助用户执行。”
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 旨在提高比特币 BTC 68,468 美元矿工的回报,这些矿工处理交易并将其发布到比特币的区块链分类账中。
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).
比特币最初是作为一种简单的点对点支付协议,但其 2021 年的 Taproot 升级使网络能够支持更复杂的活动,例如创建和交易其他类型的代币以及铸造不可替代代币 (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,比特币原生 DeFi 仍处于萌芽阶段,并且很大程度上仅限于加密货币原生交易者,因为要使用比特币 DEX,交易者必须首先在链上进行交互,为其交易账户提供资金。
“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,每日交易量最多可达数百万。这并不重要,”卢斯说。 “我们现在真正认为这个空间是一个非常早期的测试版,没有那么多用户与之交互。”
“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.”
“在接下来的 12 个月内,如果你不能在比特币上获得良好的执行力,你很可能会转向 L2,”Luce 补充道。 “我认为如果这种情况发生,那就错失了机会,因为比特币是一个非常好的市场。”
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.
据 DefiLlama 称,截至 10 月 18 日,比特币 L2 锁定的总价值约为 20 亿美元。部分比特币 L2 包括 Babylon、Core Chain、Rootstock 和 Stacks 等。
