How does a decentralized network increase security?
As the network cannot be compromised as it is decentralised.
How does a decentralized network increase security?
by mining there is no cencorship cannot double spend and cannot alter transactions nodes secure the network as they are many computers that need consensus
Why is it dangerous to trust a central authority for security?
because they can double spend and edit and change a transaction
1- All participants (miners) are incentivised to reach consensus / agreement over the state of the ledger. This is much better than having a central entity overseeing security.
2- Because central authorities (or individuals within them) can be dishonest / can be bribed - their database(s) can be altered from inside the organisation or hacked from the outside.
How does a decentralized network increase security?
it provides a global protocol that is protected by math and canât be modified or changed over time.
Why is it dangerous to trust a central authority for security?
Because that central authority can manipulate data, sell it or share it for profit to other organizations or companies, including hackers.
How does a decentralized network increase security? 
First we should have a look at the meaning of security which is âthe state of being free from danger or threatâ. Simply put if we require a network to have increased security we require that the interconnected system is in a very high state of being free from danger or threat.
A decentralized network which is built on a common security protocol has the benefit of openness and transparency for the users. With openness and transparency users of the interconnected system will a have a better understanding of structure of the network, and with this understanding we are able to place trust in the system on which is built.
Security in a decentralized network would have to be built with a common system that is governed by the laws and principles that is trust-less, and those that have access to the network follow and adhere to those laws and principles which are governed by security protocols of the decentralized network.
The main security threat of any network is about âwhoâ has access to the network and âwhyâ do they require access. Through a decentralized network which has provenance and consensus built in, security of the network is increased since we can verify first âwhoâ wants access and âwhyâ. Secure access to the network can only be granted if consensus is reached within the decentralized network which will verify and trust the security access.
The decentralized network has increased security once the network is able to come to that consensus through the provenance, access can be granted to those who require that secure access without any manipulation to the common security protocols of the decentralized system, .
Why is it dangerous to trust a central authority for security? 
With a central authority controlling security, the security is spread between different systems which may have different security criteria which we may not understand the security protocols which will differ from each other.
Having different security protocols over many different systems can compromise the security since we cannot understand the access granted to the system by those who require access.
Central authorities will each build their own security system based on their own set of protocols which can not necessarily mean that they are following the same laws and principles which we all trust.
If security principles are governed by the same central authority that created the security system then the security can be manipulated leading to a compromise in the security making it dangerous to trust a central authority.
Multiple confirmations and uncuruptible data storage.
Can be easily manipulated and corrupted.
I guess, in a centralized system. Someone has to be the cop. While this persons role is essential, it also give this âcopâ a lot of power and authority over those who arenât the cop. This creates a tension and suspicion between authority and the subjected class. With a decentralized security network, it can act as in impartial institution that nobody suspects of bias or ill intention. This leads to less conflicts which is the main point of security.
Centralized Authorities are consistently hacked which is something you canât necessarily blame them for but it is still a worry. Second, the centralized authority may not have your best interest at heart. A great example would be how Youtube has started taking down crypto currency videos of legitimate businesses by making sweeping accusations of scams and disinformation. Since it is their platform, they have the right to make the rules on that platform. If the network is decentralized, there will be less of this problem and it is likely that there will be less bias. However, isnât concensus a form of bias? I also wonder if consensus could be argued to violate the first amendment of the constitution of the united states. I hope not, but maybe.
Consensus is a set of mathematical rules on the blockchain. Why would that be biased in any way or violate freedom of speech?
1- Itâs a global database, checked by all accoring the same protocol, same standards. Open to see,
check. You trust the network, not the organisation.
2- A central authority has itâs own truth and protocols, wich can be altered at wish, of them that is. It has
no state of immutabilty, even though they claim it is.
True, Ivan might be right when he says, block chain isnât for everything. For example, a miner saying he wants to payout a bitcoin that the other miners donât agree could be considered hate speech. Hate speech is protected under the 1st amendment because what is right and wrong is subjective. One could deem consensus as a form of democracy but it would be mob democracy. Which is why the united states set up a democratic republic that would protect the rights of minority groups against majority rule.
Iâm sort of thinking way out of the box here and donât necessarily see an issue, but itâs something to keep an eye on.
A decentralised network is trust less, all information supplied to it is open and transparent so it can be verified with a consensus. Therefore security is increased because all information provided has to pass these requirements to be granted access onto the network.
A central authority can choose to omit certain information they feel would be scrutinised. They may wish to hide information that may reveal certain parameters to be dangerous to people or the environment or they could completely falsify data findings or reporting numbers.
It increases security by not having to trust a central authority but a network.
because a central authority can be hacked. Plus, the central authority can manipulate the data.
Keeps everybody on the same playing field and same platform.
Much more room for error and puts in a unreliable trust factor with this central authority.
-Decentralized networks increases security because you have massive amounts of individuals protecting the system which makes it harder for the opposition to break the system. Thatâs why a higher hash rate is better than having a lower hash rate (correct me if Iâm wrong).
1. How does a decentralized network increase security?
By holding everybody accountable there can be no one single point of failure
2. Why is it dangerous to trust a central authority for security?
You are entrusting somebody else to hold your valuable bags and do whatever they want without your knowledge or permission. A decentralised authority allows you to hold your bags and be accountable for what happens to them.
