Hi all guys and welcome back to my blog today we continue the speech treated yesterday on the blokchain clarifying a little more in detail what decentralized network means
This post is not essential in general learning on the topic of cryptocurrencies but it can be a worthy personal study on the different types of networks
Decentralization is a key feature of the blockchain. Let's talk about the differences first in general, then we'll go more into the specifics.
The main feature between Client-Server and Peer-to-Peer networks is that in the Client-Server network the management is centralized while in the Peer-to-Peer networks the management is delegated to each computer.
To avoid going into too much detail, we will list only the characteristics of the Peer-to-Peer network below ;
=> In this network there is no distinction between client and server as each host acts for both parties
=> Obviously, not being a centralized network, each host can take advantage of services made available by other hosts and can itself make services available
=> Connectivity
=> Each host has its own data and information
=> No bottlenecks can form
=> This network is less expensive as it doesn't even require a network administrator
Stability => This network is very effective and can have difficulties or slowdowns only in the event of an exponential increase of hosts within the network.
These are just some of the characteristics of this network expressed in a very simple and approximate way as it has relatively little to do with the topic, having said that let's continue with the blockchain.
the blockchain instead of having a centralized entity (client-Server) to manage the chains of the various blocks uses a Peer-to-Peer network to which everyone can join.
But what is the fundamental thing, well every time someone enters the network a copy of the blockchain is made.
If a block is added to a host then in our case a transition all the other hosts verify the authenticity of the transition through the proof of work and once verified each host adds a node to its chain.
If not, then if this block is rejected it will not be copied to the other hosts' blockchain.
Now comes the funniest part if a hacker would like to tamper with a block he should modify then hack at least 51% so the majority of hosts on the network and this as we can well imagine is an impossible thing precisely for reasons of time.
it is precisely for this reason that the bitcoin network, but not only, is a safe place at least for today's technologies.
Final report the blockchain is a centralized network in which each host has a copy of the network and this allows it not to be tampered with, to ensure that the entire network is tampered with it would be necessary to modify the chain of at least 51% of the hosts connected to the network and it's IMPOSSIBLE
Hello everyone, thank you again for reading and if you have come this far, thank you, I apologize if this lesson was slightly different from the others but it was, let's say, a sort of in-depth study.
Having said that we will return to talk about the blockchain in particular of the first crypto or BTC, I won't tell you more stay connected sign up and thanks again for your time.
