My teacher said multiple times during a discussion that you can DDOS a blockchain

>> No.13860134

>>13860128
if course you can. The nodes are computers on the internet and they can be flooded.

I assume it's a she. Does she know what a blockchain is?

ethereum was 'DDOSed' by crypto kitties.

You can DDoS any server. I love when people do this. They’re like “well, I mean, blockchain doesn’t end world hunger. And did you know it doesn’t lick your asshole while jerking you off? Really makes me wonder if it is a worthwhile technology...”

kek they were probably trying to cope with missing crypto and being a teacher

>> No.13860167

>>13860134
So you can ddos the ISP they're on. Even if the whole network goes down, the blockchain remains in tact on the hard drives of the individual nodes. When it comes back online, the longest chain will be the one adopted by everyone on the network. Sure, some fucky shit can go on in the downtime by a collection of CPUs working together to fake transactions, but the blockchain itself is still secure

It's like saying you can ddos a spreadsheet

it's like saying you can ddos a spreadsheet service's servers. Which is a perfectly fine statement.

Each node is connected to a limited amount of other nodes. If you ddos a few nodes intelligently, you can cleave the network and make double spends.

Nodes are connected through a network.

There are mechanisms to avoid it: In a chain with gas/fees, you spend a lot of money on the attack. In a chain where tokens equal resources, you can never exceed the resources assigned to you by your holdings.

Technicality that's correct, but that's obviously not what she meant, because she has no idea what she's talking about

This.
Man, this is what happens when a bunch of normies get crazy amounts of money out of nowhere. They spend $800 on a digital cat. No wonder they stay poor.

i mean you can flood it with transactions...

>> No.13860939

>>13860198
Yes, but perhaps the statement "You can DDOS a blcokchain" is, in its context, implying a simplicity or ease of doing so, and a false comparison to other things. The mechanisms by which a blockchain network secures itself against such attacks are the notable points.

>> No.13860955

>>13860925
You can cleave the network in two, make double spends up the wazoo, and stop the ddos on nodes, reconnecting the network.

>> No.13860971

Spam lots of micro transactions with high gas fee. You will burn a lot of gas so if you can sustain it, it will cripple the blockchain.

Kek. I'm using this argument at work tomorrow to describe tech in general.
