内容摘要:

We examine the impact of vampire attack, a unique platform entry strategy in the blockchain ecosystem, on the operational performance of the incumbent platform. During the vampire attack period, the entrant attacker clones the targeted incumbent’s business model and drains liquidity from the incumbent to its cloned platform by providing tokenized incentives to the incumbent’s liquidity providers. Prior studies offer little insight into the impact of vampire attack strategy because of its uniqueness in platform cloning, tokenized incentives, and targeted attacks. Our study provides significant contributions to this nascent platform entry strategy. We implement a quasi-experimental design by leveraging the vampire attack launched by Sushiswap (the attacker) against Uniswap (the incumbent). We examine both the deposit-side and exchange-side impact of the vampire attack on the operational performance of the liquidity pools on Uniswap. Surprisingly, we find that the vampire attack has no significant effect on the liquidity provision on the deposit side. Even more surprisingly, the vampire attack significantly increases the incumbent’s trading volume on the exchange side. We further uncover the underlying reasons contributing to these intriguing results and reveal the differential impact of the vampire attack on the market for new and existing users.

我们研究了区块链生态系统中一种新兴平台进入战略对在位者运营绩效的影响。在该战略实施期间,进入者克隆了在位者的商业模式,并对在位者的流动性提供者进行代币化激励,以期将他们引流到其克隆的平台。由于该战略在平台克隆、代币化激励和针对性攻击等方面的独特性,现有平台进入战略的研究对于理解其影响的帮助有限。我们的研究为这一新兴的平台进入战略做出了重要贡献。我们基于 Sushiswap(进入者)对 Uniswap(在位者)发起的进入战略来进行准实验性设计。我们研究了该战略对在位者流动性池的存款端和兑换端运营绩效的影响。令人惊讶的是,我们发现该战略对在位者存款端的流动性供应没有显著影响。更令人惊讶的是,该战略显著增加了在位者兑换端的交易量。我们进一步揭示了导致这些有趣结果的原因,并揭示了该战略对新用户和现有用户市场的不同影响。
