Improving Bitcoin Protocols against attack

[bombproof]

I have lots of experience with networking and I am a bitcoin fan.  I have ideas on how to fix some weaknesses in the bitcoin architecture that could be exploited by institutions that would want to shut down bitcoin.  Which is the right group to post these types of topics?

Thanks,

Most likely would be the Bitcoin Discussion area.

Most likely would be the Bitcoin Discussion area.

A "Fix to weaknesses in bitcoin architecture" would be rather technical, they don't fit in the Bitcoin Discussion area in my humble opinion.

His topic would be best suited in the Bitcoin Technical Support board, although if it's mining-related, this section would fit best.

Alternatively, you can just post it here and then let the moderators decide where to move it to.

Interesting i am looking forward to see what you have to say but looks a little impossible to shutdown the bitcoin network, maybe is the same level of difficulty to shutdown the internet? In any case i would like to read you about those weaknesses

Matt I appreciate your videos.  And I appreciate you addressing 'what if' scenarios related to bitcoin.  I think that there is a 'what if' possible threat from internet service providers.  The bitcoin network uses a specific socket (or port) on the internet.  Packets are sent to these specific ports as part of the peer-to-peer information exchanges.   It is possible that governments could ask ISPs to stop routing packets that are destined for this specific socket.  This would stop blockchain updates.  Can you comment on this threat?

I think it's a very good question. I'd love for Matt to make a video on this. It seems to me that governments "asking" ISPs to block access to the blockchain is a serious issue worth discussing

1. ALL governments would have to do it simultaneously. 2. Even if they did, just switch to a different port.

 @Hugo-ew2ko  Just the government that is in control of your immediate routers would be able to shut you off from bitcoin.  How long would it take to coordinate the world switching ports on every bitcoin node?  Very long, and the government could have lots of time to block that port.

Where does this conversation happen? So basically your goal is to solve this port-blocking issue? I think the point that the government can easily block your access is quite overstressed here. While they can force your ISPs to do it, I doubt it would be faster than people moving to different ports or randomizing it. CMIIW.

Anyway, I second the suggestion to move this to development & technical discussion instead of the mining board. You can do it by clicking the move button on the bottom left of your thread.

I want to bring up this possible weakness of the bitcoin protocol in order to make bitcoin less vulnerable. Please feel free to move this discussion to whichever group is most appropriate.

Considering the number of nodes running on TOR: https://bitnodes.io/nodes/?q=.onion

It's not that big an issue. Even if SOME ISPs blocked the ports other ISPs would not. Add in VPNs and people running their own BGP for their own IP space would have more freedom to do what they want.

Um, don't think so - I don't even use the standard port for some of my bitcoind ... and they work fine.
The port is included in the protocol that tells about other nodes.
So, as soon as you switch your port, it works fine.
