The Security Budget Flaw That Proof-Of-Stake Introduces
The proof-of-work mechanism in Bitcoin provides security which Ethereum has sacrificed for short-term narrative benefits.This is an opinion editorial by Mickey Koss, a West Point graduate with a degree in economics. He spent four years in the infantry before transitioning to the Finance Corps.Ethereum founder Vitalik Buterin recently voiced concerns about Bitcoins long term security citing relative security budgets based on network fee structures. These concerns are unfounded and structured upon a false comparison between the two systems. Here’s why:First, Ethereum’s proof-of-stake....

Here is a reality check for all the Bitcoin naysayers, the most widely used conventional electronic payment system – credit/debit cards are not really as secure as we had earlier thought. A serious protocol level flaw exposed by a couple of German security experts bares it all. It is not just the security flaw one has to be concerned about, but also the banks’ apathy towards fixing it! A recent report carried by well-known Russian media channel, Russia Today describes the serious security flaw in POS terminals. According to Karsten Nohl, one of the security experts from the Berlin based....
Not that anyone is asking, but Coin Center inserted itself into the debate at hand. Is the Post-Merge Ethereum a security now? Moving from Proof-Of-Work to Proof-Of-Stake without pausing the operation was quite a feat, but it came with a cost. Many things are completely different at this stage, and those new characteristics might put […]
This week, Bitcoinist has published two excellent articles on the topic of DPOS, or delegated Proof of Stake. Both written by Alberto Mata, DPOS is a new feature that Bitshares is talking about, which they believe solves problems of both proof or work and proof of stake systems alike, adding another layer of security by countering the negative effects of trust centralization. One fact that is pointed out however is that it a DPOS system is still vulnerable to 51% attacks, but the cost would be much higher compared to another systems.

The security expert said that while PoS isn’t “theoretically” as secure as PoW, he admits it still has “sufficient practical security.” Despite the Ethereum Merge being touted as a major upgrade to the blockchain network, its transition to proof-of-stake theoretically makes it more vulnerable to exploit.Speaking to Cointelegraph, the security researcher explained that unlike proof-of-work (PoW) systems, a proof-of-stake (PoS) system informs node validators in advance what blocks they will validate, thus enabling them to plan attacks. The security expert, who asked not to be named, is a....
What is delegated proof of stake? “(DPOS) Delegated proof of stake is a new consensus algorithms that allows shareholders (or the users of the system) to have control over who is certifying the ledger. it allows us to have 10 second block times, process 10 transactions per second or more, and allows the network to scale; to have dedicated nodes that are highly efficient and specialized yet remain in control of the shareholders. We can actually have 10 second confirmation on your blocks that is more secure than bitcoin.” How is DPOS different than proof of stake or proof of work? “Proof of....
