The blockchain trilemma, introduced in 2017 on a blog post authored by Vitalik Buterin, one of Ethereum’s co-founders, asserts that achieving decentralization, scalability, and security simultaneously within a blockchain is unattainable. While this

Abstract The measurement error of the network topology caused by missing network data during the collection process is a major concern in analyzing collected network data. It is essential to clarify the error between the properties of an original net

Deep neural networks (DNNs) achieve higher accuracy as the amount of training data increases. However, training data such as personal medical data are often privacy sensitive and cannot be collected. Methods have been proposed for training with distr

Blockchain consensus, which enables nodes on a peer-to-peer network to agree on the same ledger history, is the core element of blockchain systems. In many blockchain systems, a node chosen as a block proposer, in accordance with the consensus protoc

Analysis of social networks with limited data access is challenging for third parties. To address this challenge, a number of studies have developed algorithms that estimate properties of social networks via a simple random walk. However, most existi

Many complex systems involve direct interactions among more than two entities and can be represented by hypergraphs, in which hyperedges encode higher-order interactions among an arbitrary number of nodes. To analyze structures and dynamics of given
