A Dataset of Early Blockchain-Registered AI Agents on Ethereum

Yulin Liu

A data descriptor covering 10,000 AI agents registered on Ethereum under the ERC-8004 standard, combining on-chain identity, transfer and reputation records with resolved off-chain metadata.

Empirical Analysis of EIP-1559

Transaction Fees, Waiting Times, and Consensus Security

Yulin Liu, Yuxuan Lu, Kartik Nayak, Fan Zhang, Luyao Zhang, Yinhong Zhao

Uses blockchain, mempool and exchange data to estimate the causal effects of EIP-1559. The mechanism reduces waiting times and intra-block fee dispersion but has little effect on fee levels or consensus security.

Deciphering Bitcoin Blockchain Data by Cohort Analysis

Yulin Liu, Luyao Zhang, Yinhong Zhao

Applies cohort analysis to Bitcoin transaction inputs and outputs, producing daily datasets on the lifespan of spent outputs and the age distribution of unspent outputs.

Versatile Forward Guidance

Escaping or Switching?

Hans Gersbach, Yulin Liu, Martin Tischhauser

Compares two forward-guidance designs under negative natural real rates: an escape clause triggered by an inflation threshold, and the option to switch from interest-rate to inflation forecasts. Switching is preferable only when negative real-rate shocks are moderate.

Forward Guidance Contracts

Hans Gersbach, Volker Hahn, Yulin Liu

Studies contracts that penalize central bankers for setting high interest rates in a New Keynesian model. Such contracts can help an economy escape a liquidity trap, and optimal contract durations are short.

Cryptocurrency Valuation

An Explainable AI Approach

Yulin Liu, Luyao Zhang

Proposes a price-to-utility ratio for Bitcoin grounded in monetary theory and UTXO accounting, and evaluates its predictive power for long-horizon returns using interpretable machine learning.

SoK: Blockchain Decentralization

Luyao Zhang, Xinshi Ma, Yulin Liu

Systematizes the measurement of blockchain decentralization across consensus, network, governance, wealth and transactions, and proposes an entropy-based index with an open-source toolkit.

The Economics of Blockchain Governance

Evaluate Liquid Democracy on the Internet Computer

Yulin Liu, Luyao Zhang

Models and simulates liquid democracy in the Internet Computer's Network Nervous System, examining how staking rewards align members' short-term incentives with long-term governance outcomes.

Blockchain Network Analysis

A Comparative Study of Decentralized Banks

Yufan Zhang, Zichao Chen, Yutong Sun, Yulin Liu, Luyao Zhang

Applies core–periphery network analysis to the token transaction networks of Liquity, Aave, MakerDAO and Compound to compare their degree of decentralization.
