以太坊上的自动做市商

in #chinese3 years ago

AMM的教父Bancor推出了Bancor v2.1,以一种新颖、简单、可能改变游戏规则的 "解决方案 "来解决无常损失。
在v2.1中,Bancor在v1的基础上做了三个非常简单的改变,这可能会对AMM产生深远的影响。

第一个变化是LP只需要将一个代币放入流动性池。流动性池的另一半由Bancor协议提供,并以新发行的BNT(Bancor协议代币)的形式存在。

第二个变化是,费用并不是全部给LP们。由于LP们只在流动性池中投入了一半的价值,所以他们只收到一半的交易费。另一半归Bancor协议。这些费用最终会在解押时被烧掉。

第三个,也是最深刻的变化是,Bancor通过铸造新的BNT来补偿LPs的任何IL,以弥补损失。

Bancor v2.1核心是单边流动性,通过铸造新的BNT来与存入资金池的代币配对。本质上是Bancor协议与单边流动性的提供者共同做市。协议赚取资金池交易费用的一半,当单边流动性从资金池中移除时,铸造出来的BNT连同Bancor赚取的交易费用一起被烧毁。

Bancor是否会在未来几个季度继续增长,还有待观察。

虽然Bancor是第一个建立在以太坊上的自动做市商(AMM),但它对市场一直没能产生明显的吸引力,Uniswap最终成为行业的领导者。Uniswap是一个通过自动做市商(AMM)工作的去中心化交易所,是所有DeFi协议中通过TVL最成功的。

即使在2020年DeFi的夏天,Bancor的交易量仍然很低,其市场份额在图表上几乎看不到。然而,自V2.1版推出以来,Bancor的命运终于开始转变,流动性和交易量在随后的几个月里实现爆炸性增长。
