Ethereum ECCPoW
Hyoungsung Kim, Jehyuk Jang, Sangjun Park +1
The error-correction code based proof-of-work (ECCPoW) algorithm is based on a low-density parity-check (LDPC) code. The ECCPoW is possible to impair ASIC with its time-varying cap…
Time-Variant Proof-of-Work Using Error-Correction Codes
Sangjun Park, Haeung Choi, Heung-No Lee
The protocol for cryptocurrencies can be divided into three parts, namely consensus, wallet, and networking overlay. The aim of the consensus part is to bring trustless rational pe…
Blockchain-Based Distributed Patient-Centric Image Management System
Mohamed Yaseen Jabarulla, Heung-No Lee
In recent years, many researchers have focused on developing a feasible solution for storing and exchanging medical images in the field of health care. Current practices are deploy…
Profitable Double-Spending Attacks
Jehyuk Jang, Heung-No Lee
Our aim in this paper is to investigate the profitability of double-spending (DS) attacks that manipulate an a priori mined transaction in a blockchain. It was well understood that…
Intentional Aliasing Method to Improve Sub-Nyquist Sampling System
Jehyuk Jang, Sanghun Im, Heung-No Lee
A modulated wideband converter (MWC) has been introduced as a sub-Nyquist sampler that exploits a set of fast alternating pseudo random (PR) signals. Through parallel sampling bran…
An Information Theoretic Study for Noisy Compressed Sensing With Joint Sparsity Model-2
Sangjun Park, Nam Yul Yu, Heung-No Lee
In this paper, we study a support set reconstruction problem in which the signals of interest are jointly sparse with a common support set, and sampled by joint sparsity model-2 (J…
