Description
TL;DR: A structured comparison of three blockchain governance models and the security tradeoffs each carries into real-world applications.
About This Document
Hamed Taherdoost and coauthors compare public blockchains with permissioned private and consortium systems. The paper examines decentralization, transparency, governance, access control, privacy, scalability, double spending, smart-contract vulnerabilities, resilience, and examples in sectors such as supply chains and healthcare. Its central point is that no model maximizes every desirable property at once.
Why Bitcoin People May Care
Bitcoin is the obvious public-chain reference, but this is a broad blockchain-adoption study rather than a Bitcoin network audit. It is useful because it resists the lazy assumption that private, public, and consortium ledgers are interchangeable. Each model moves trust and attack surfaces around; it does not simply remove them.
