Web3 and DeFi are widely advocated as innovations for greater financial inclusion and democratization. We conduct an initial investigation using data from the Ethereum network. We describe its network structure and distributions of transactions, mining, and ownership. Mining and ownership of...

Web3 and DeFi are widely advocated as innovations for greater financial inclusion and democratization. We conduct an initial investigation using large-scale computing and big data concerning Ethereum, the largest Web3 platform. We describe its network structure, time trends, and distributions of...

Web3 and DeFi are widely advocated as innovations for greater financial inclusion and democratization. We assemble the most comprehensive dataset to date on the largest Web3 ecosystem and use large-scale computing to conduct an initial investigation. We describe Ethereum's network structure,...

Bitcoin blockchain has grown into an active global virtual money network with millions of accounts.We propose a Sparse-Group Network AutoRegressive (SGNAR) model to understand the dynamics of its cross-border transactions. It describes the money flows of virtual funds, with a focus on the...

Known as an active global virtual money network, Bitcoin blockchain with millions of accounts has played an ever-growing important role in fund transition, digital payment and hedging. We propose a method to Detect Influencers in Network AutoRegressive models (DINAR) via sparse-group...

As a highly disruptive digital technology, blockchain provides new solutions for reshaping corporate governance mechanisms and improving resource allocation. We empirically examine the relationship between blockchain and corporate investment inefficiency. We find that blockchain can help improve...
