Secure Hierarchical Deterministic Wallet Supporting Stealth Address, Xin Yin, Zhen Liu, Guomin Yang, Guoxing Chen, Haojin Zhu

Research Collection School Of Computing and Information Systems

Over the past decade, cryptocurrency has been undergoing a rapid development. Digital wallet, as the tool to store and manage the cryptographic keys, is the primary entrance for the public to access cryptocurrency assets. Hierarchical Deterministic Wallet (HDW), proposed in Bitcoin Improvement Proposal 32 (BIP32), has attracted much attention and been widely used in the community, due to its virtues such as easy backup/recovery, convenient cold-address management, and supporting trust-less audits and applications in hierarchical organizations. While HDW allows the wallet owner to generate and manage his keys conveniently, Stealth Address (SA) allows a payer to generate fresh address (i.e., …

We show that ongoing zero portfolio weights in cryptocurrency are surprisingly difficult to generate in a standard Bayesian portfolio theory framework. With ten years of prior data, equity market investors would need very pessimistic priors on mean returns to justify never having bought cryptocurrency: -10.6% per month for Bitcoin, and -19.6% per month for a diversified portfolio of cryptocurrencies. Moreover, most priors that involve never purchasing cryptocurrency imply that investors should short cryptocurrency. Optimal absolute weights are generally small but non-trivial (1-5%), frequently positive, and fairly smooth despite returns being volatile. Under a wide range of priors, the certainty equivalent …

Coinbase is a cryptocurrency exchange founded in the U.S during 2012 by Brian Armstrong and Fred Ehrsam. Coinbase’s application allows users to buy, sell, and exchange different cryptocurrencies on the open market. Cryptocurrencies are digital assets used as a medium to quickly transfer value, globally, without any middleman. Some cryptocurrencies have different technology than others, but all are based on blockchain, and cryptography. Blockchain technology allows transactions to be built into a chain that is forever accessible, hence the name “public ledger.” Cryptography is what ensures ultimate ownership, through seed phrases, and security through encryption. Coinbase has several large competitors …

The Blockchain is a distributed database that is maintained as Blocks and contains all transactions or digital occurrences. These are the records of transactions that take place between parties.Blockchain blocks are kept as blocks and shared among participants. Each Block is examined, validated, and saved by the parties who are a part of the system/network, each brick is unique and contains the details of a single transaction as well as the transaction's hash key. The study offers insights to researchers about the opportunity threat and future use of blockchain in the public sector.


Flight To Bitcoin, Yang Yu, Jinyuan Zhang Feb 2022

Flight To Bitcoin, Yang Yu, Jinyuan Zhang

Research Collection Lee Kong Chian School Of Business

This paper uncovers an overlooked motivation of Bitcoin investment: investors hold Bitcoin as an asset on which government authorities have limited influence. Consistent with this motivation, we document a flight-to-Bitcoin (FTB) phenomenon whereby local demand for Bitcoin increases with local economic policy uncertainties and Bitcoin ownership shifts from centralized exchanges to decentralized wallets amid such turbulence. FTB is driven by investors’ lack of confidence in government as FTB is stronger in countries where the confidence in government is low and corruption incidents surge. Finally, a comparison with safe-haven assets further differentiates FTB from flight-to-safety.

Researchers interested in blockchains are increasingly attuned to questions of governance, including how blockchains relate to government, the ways blockchains are governed, and ways blockchains can improve prospects for successful self-governance. Our paper joins this research by exploring the implications of the Governing Knowledge Commons (GKC) framework to analyze governance of blockchains. Our novel contributions are making the case that blockchain networks represent knowledge commons governance, in the sense that they rely on collectively-managed technologies to pool and manage distributed information, illustrating the usefulness and novelty of the GCK methodology with an empirical case study of the evolution of Bitcoin, …
