中心化交易所交易如何影响权益证明质押

总结

本文建立模型，研究中心化交易所交易可能如何影响权益证明区块链中的质押选择和代币分布。在其连续时间均值场框架中，参与者既是验证者，也是中心化市场中的交易者，交易会产生价格冲击。作者在既定假设下证明了局部适定性，并对均衡交易行为给出半显式刻画。

数值结果表明，中心化交易可能通过市场激励提高质押参与度，并使质押分布更为分散。研究还考察了交易成本和代币供应机制如何影响均衡质押比例和集中度。这些是基于模型的发现，并非交易所活动会使现实网络去中心化的实证证据。结论取决于模型假设和市场结构；摘录没有说明校准细节，也没有量化这些影响在不同协议中的稳健性。

核心观点

  • 该模型将中心化交易所交易与权益证明系统中的质押选择联系起来。
  • 参与者既被视为验证者，也被视为面临价格冲击的交易者。
  • 均值场框架在其假设下刻画均衡行为。
  • 数值结果表明，交易所交易可能提高质押参与度并降低集中度。
  • 交易成本和代币供应机制可能改变质押比例和集中程度。

# Proof of Stake economy under centralized exchanges--a mean field model









We consider the interaction between centralized trading and decentralized Proof of Stake (PoS) blockchain ecosystems. Motivated by the increasing dominance of centralized exchanges and the institutionalization of crypto markets, we study how trading activities on centralized exchanges affect staking behavior, token allocation, and decentralization within a PoS blockchain. We formulate a continuous-time mean field model, where the miners simultaneously act as validators in the PoS protocol and traders in a centralized market with price impact. Under suitable assumptions, we establish the local well-posedness of the mean field system, and derive a semi-explicit characterization of the equilibrium trading strategy. Numerical results suggest that centralized trading activities may enhance staking participation, and promote decentralization of the staking distribution through market incentives. We also study the effects of transaction costs and token supply mechanisms on the equilibrium staking ratio and concentration profile. These results illustrate how market microstructure and centralized liquidity provision can exert significant influence on decentralized blockchain protocols.
