[虚拟币资讯] 详解MEV的运作方式:有多黑暗?以太坊合并对其有何影响?

摘要:

  • 最大可提取价值(MEV)是矿工通过对区块中的交易进行排序而获取的利润。

  • DeFi的智能合约系统利用低效优势,提供了多种收入来源。

  • 套利是链上获利最常见的方式。

  • 对于矿工来说,Flashbots减少了负外部性,同时也产生了更多的收入。

MEV

MEV代表Miner(矿工)或Maximum Extractable Value(最大可提取价值)。

矿工(或验证者、序列器)在其生产的区块中通过其能力任意打包、排除或重新排序交易可以获得一定的利润,而MEV 便是衡量该利润的一种度量。矿工必须能够对交易进行优先级排序,以防止未经许可的区块链受到spam(垃圾邮件)和 DoS 攻击。

内存池(mempool)是理解矿工活动的基础。

内存池

内存池是一个电子文件,其中包括未经确认的交易。其中每个区块包含的未确认交易笔数是有限的。矿工在选择哪些未确认交易将被打包进区块方面拥有完全的自主权。当交易被选中打包后,就会被存储在一个新的区块中,并将其广播。

矿工通常会优先选择打包费用较高的交易,以实现利润最大化。

这促使他们寻求能够给他们带来更多利润的其他途径。

然而,做这件事的并不只有矿工:机器人扫描内存池,将打包的交易放在用户交易之前或之后,以提取价值。

可以想一下,有人在你之前购买某个代币,然后同样的代币以更高的价格卖给你!

为了减轻处理交易对主链的影响,一个MEV研究小组创造了Flashbots。

Flashbots

通常,矿工通过以太坊公共内存池竞标MEV。

通过Flashbots,研究团队创建了一个开放的沟通渠道,使拍卖和MEV竞标可以在私人内存池上进行。

详解MEV的运作方式:有多黑暗?以太坊合并对其有何影响?

搜索者(Searchers)是这一过程中的关键参与者:他们能够利用Defi市场中的信息不对称。由于搜索者的激烈竞争,矿工可能只会选择支付最高交易费用的交易包。搜索者向矿工支付高额的交易费用来执行捆绑。

此时,搜索者:

1.直接向分析报价的矿工出价购买区块空间。

2.将gas费降至最低,以最大限度地提高MEV回报。

3.在不降低MEV结果的情况下,为区块空间出价更高。

对矿工来说,MEV等激励措施多样化是至关重要的。如果单个矿工具有拥有获得回报的经常性优势,它可能会成为主要的区块生成器,进而会制造劣势。

如果不使 MEV 民主化,那么可能会导致利益的分配和累积不断集中化。

Flashbots Auction通过向搜索者和矿工提供获利了结功能,使MEV大众化。一些矿工在跟踪搜索者的活动后试图执行他们的交易,对此,该途径还制定了行为准则,以保护搜索者免受矿工的影响。
