Hello everyone, I have a question. Solano Blockchain network was overload two days ago, how was it possible for the network to be shut down? Doesn't that mean Solana Blockchain is centralized?

I don't think that this was the case with SOL.

However, not all cryptos are decentralized.

Just look at something like XRP, it is clearly not decentralized because its sole value derives from the fact that they have integrations with centralized financial institutions. Or something like Tether, which solely depends on the backing on the issuing agency.

The emergence of various public chains has gradually weakened my enthusiasm for Ethereum, because Ethereum is really unaffordable and too expensive. Decentralization is not so important for traders who want to make profits in a short time.

Only poor people say Ethereum is too expensive and if you hate Ethereum for its price then you are the first fool to hate Ethereum at this point because in the past so many people prayed for Ethereum's price increase and hoped that Ethereum would be better than it was.

The problem really took many investors by surprise especially when solana network is supposed to be able to handle quite a number of transaction per second, it was shocking to see the network breakdown like that, I don't think solana can be considered 100% decentralized network, some part are centralize.

Supposedly yes, its decentralized and I’m also confused on how they shut down their own network or maybe they just unplugged the server and the result is this? Still centralized though not unless the nodes are owned by the investors and not by the team only.

To me, any other blockchain aside from Bitcoin blockchain is centralized and its operation can easily get manipulated by its developers because they have all the codes which make it always vulnerable, but we have some high, strict blockchain that is highly decentralized.

It is inherently decentralized . Blockchain does not store any of its information in a central location.Blockchain is copied and spread across a network of computers. Decentralized blockchains are immutable.

When you're building a blockchain and your blockchain has hundreds of nodes but these nodes owned by your communities. This can be called a centralization. It doesn't store information to be centralized in one nodes but when these nodes controlled by the same party and you must remember about 51% attack. Solana blockchain has more than 1k nodes but these nodes run by not so many parties. Technically blockchain was not centralized but people who have been running the nodes were making it to be centralized. There will always be a chance for the collusion to happen in the blockchain when it was running by a few parties.

it can be concluded that the Solana network is actually decentralized with various nodes. but all the nodes are fully controlled by them.

that means solana was not decentralized. There are only 200 nodes actively securing the network and this is very small amounts. That's why the instability could affect the network instantly.
If there are only a few nodes became offline on ethereum blockchain and this will not give the same impact like SOL as there are bunch of nodes were still active.
SOL was only running by a few nodes and it doesn't mean it will be decentralized. if these nodes controlled by a few parties and SOL chain was totally centralized.
that's the point. I guess sol was adopting the same thing like what BSC did in the past. Trusting some parties to run the nodes. This is not what we called as decentralization.

from : https://thedefiant.io/solana-instability/ they said : Some nodes on the smart contracts chain went offline after the network had problems handling a higher-than-usual load, according to a spokeswoman for the team. From the sentence above, it can be concluded that the Solana network is actually decentralized with various nodes. but all the nodes are fully controlled by them.

Quote from: https://solana.com/

Solana is a decentralized blockchain built to enable scalable, user-friendly apps for the world.

I also thought the same thing, but if you visit their website, you can see the post above.
As I know from several articles at the time, that the Solana network was down and I don't think the blockchain was down, because I can still access my wallet and can
see the balance in the wallet. correct me if i'm wrong.

If we look at the important focus of the Solana foundation as stated in CMC that Solana's important focus is to make decentralized finance accessible on a larger scale. Of course if in reality this is what happened to Solana as you mentioned, I am automatically surprised too. However, I want us not to make decisions directly until someone really knows what really happened.

Decentralisation depends on the number of miners or validators. It means that the more miners are, the more decentralised this blockchain is. So to find out if one is decentralised or not, you should check this information. I don’t follow Solana, but I know that it claims to be decentralised and there are approximately 1000 validators, which is not very much compared to Ethereum.

I don't think it's right to blame Blockchain for that. I have researched in the past about Solana to see what's made of, and whether it's decentralized or not, I haven't seen much. Before I use a cryptocurrency, I first of all check how easily I can run its full node and participate in the network.
The shutting down, for even an hour, not a good sign in my opinion.

A Bitcoiner chooses. A slave obeys.

I think the rate of adoption is the most important indicator of how much a blockchain is decentralized. Some are more decentralized, while others are less decentralized. But then again Im sure there are other factors too. Undecided

It depends, like Bitcoin blockchain, you can see how decentralized it is. But how about having a blockchain that only a few set of miners will only be the one to be able to mine, that is not decentralized.

Like ripple (XRP) blockchain, it is obvious how centralized it is.

About Solana, I do not know exactly what happened, but if true that the network was shutdown, it seems more centralized in my opinion, blockchain supposed to be designed in a way it will be available everytime as decentralized it should be.

I've only been seeing Sol as it's pumping but I'm not aware how's their protocol towards their own network. I'm not aware that they're able to shutdown their network and if that happened then there's a possibility that they're controlling in.
And that leads to the idea that they're not decentralized, this is only a guess if they're the one that has shut it down. But if not, because it's possible that their network has shut down due to some constraints by its own chain.

Maybe they run more than 50% of their network to be able to shutdown the network and it is not a decentralized network. If they really are decentralized then the event of their network shutting down will just make people think that it's centralized instead of decentralized.

Yes it is totally centralized junk that is running on cloud servers Hetzner and others, so if anything happens to this servers or if they have maintenance, everything hosted there will be down including solana.
Few months ago I saw that two datacenters account for 45% of validators in this fake decentralized coin, so if 33% of network goes down (like it happened) transactions can't be confirmed.
Similar thing is with most altcoins including ethereum, and I would dare to say that Bitcoin is probably only real decentralized cryptocurrency today.

Quote from: Magicalking on September 16, 2021, 03:14:31 AM

So if 51% of the miners agree it is possible to be paused.

This can not happen in Bitcoin, blockchain will continue to work and 51% of miners can't ''pause'' Bitcoin.

Yes and No, blockchain is just like the processing engine not the actual components so if you want to ask the right questions next time it should be ' are decentralized coins or projects really decentralized' since the components of Decentralisation starts from the project (coins/tokens) running on blockchain itself
