Title: DDOS the miners? Post by: spooderman on October 20, 2014, 08:27:12 PM I assume it is well established that this is not possible or a question that would only be asked by someone with little technical understanding.
I'd just like to know why it's presumably not possible, because it would be a pain wouldn't it? Sending lots of useless information to the network? How can we rely on people only sending transactions to the network? What don't I understand here? Thanks. edit: I'm not saying their useless info would end up in the blockchain, I'm just saying the nodes would have to deal with loads of spam all the time. edit: get technical, I love it :D Title: Re: DDOS the miners?

https://bitcointalk.org/index.php?topic=128548.0 Protections I can think of are: - tx fee (and the minimum tx fee) https://en.bitcoin.it/wiki/Transaction_fee - tx relay policy (only valid tx with valid fees are relayed) - only valid blocks are relayed. - blocks have a maximum size - a node that continue to receive invalid tx/blocks from another node will disconnect from that node That's my lay understanding of it. |
