Proof of stake is incapable of producing a consensus (yanmaani.github.io)

Article summary

The article argues that proof of stake is incapable of producing a consensus and is therefore not a viable alternative to proof of work. It claims that proof of stake systems are fundamentally insecure and can be attacked by malicious actors. The article also discusses the history and mechanics of proof of work and proof of stake systems. The author concludes that proof of stake is not a consensus mechanism and that any working system using it must have a real consensus mechanism behind it.

Main themes

• proof of stake vs proof of work
• consensus mechanisms
• cryptocurrency security
• censorship and free speech
• private enterprise and democracy
• trust and stakeholders
• 51% attacks and network security

What commenters say

• Some argue that the security of cryptocurrency systems relies more on trust between stakeholders than on the consensus algorithm itself.
• Others claim that proof of work has economic flaws that make it vulnerable to attacks, such as renting mining power to perform double spends.
• There are concerns that private enterprises controlling digital platforms can censor speech and undermine democracy.
• Freedom of speech does not guarantee an audience, and some argue that it is not the same as requiring others to listen.
• The first amendment does not apply to private enterprises, and any changes to this would require a constitutional amendment or nationalization.
• Some believe that the security model of cryptocurrency should not rely on exponential increases in value.
• Others argue that the threat of 51% attacks on proof of work networks is real and has been demonstrated in practice.
• There are different opinions on the effectiveness of proof of work in protecting against attacks, with some arguing that it only protects the largest projects with unique hash algorithms.
