Topic: Can Bitcoin be stopped by ISP by blocking the nodes/miner? (Read 249 times)

I thought so that in India everything is forbidden, including crypto/mining

Hello! It is interesting to learn more opinions about this, since it is not clear then what to do next?

If you run a mining node, Ideally you should be using a VPN. No government can stop you node from "talking" with other near by nodes.They will have to shutdown the internet. It is a software you download, and as long as you have internet connections, you can be a part of the network. It is not like some kind of website you can shutdown

Sorry to say, but this makes very little sense... With the explanation you've given, you shouldn't have added the "very simple dude*" remark at the bottom... I guess your heart is in the right place, but it takes a lot of imagination to make something meaningfull out of your comment.

A full node is a program that is connected to other full nodes to form the network. Each full node verifies all new blocks and transactions it receives directly from users, directly from miners or indirectly from other nodes. When a received unconfirmed transaction or a new block got verified and is valid, the node relays it to other nodes it's connected to. The node stores the new valid blocks in his copy of the complete blockchain stored locally and the valid unconfirmed transactions in his UTXO set.

If the node is owned by a miner, the miner can use the node to get the hash of the header of the last valid block in the blockchain, an address whose private key is owned by the pool operator, the current target and unconfirmed unspent outputs to fill the block, build the merkle tree to go in the new header (and cash in on the fees that can be added to the coinbase transaction). Offcourse, in reality, there are functions built in to the node software that makes these queries a lot easyer than querying all this data seperately.

As for your post:
Nodes do not act as a medium, they form the network
Nodes do not send signals to the chain, they relay new (valid) blocks and unconfirmed (valid) transactions
Nodes do not make miners clean and safe, they just reject invalid blocks and transactions and are used (sometimes directly) by miners to get all the data they need to start hashing

As for the question asked by the OP: i agree with the other posters... If your country decides to block a port, there are ways around it that can be used with varying levels of success: proxy, VPN, VPS, Tor, using an SPV wallet, changing the port,...
HOWEVER, you should know the reasoning behind blocking a certain port before you can try to find a workaround... If your country blocked the port because crypto is illegal in your country, it might be a reasonable idear to consult a lawyer before implementing a workaround...

They can only stop website and apps. That also you can access using either Brave browser or TOR. Brave browser has got build-in TOR network which acts as a VPN enabling you to access porn and other thing banned in your country.

They even cannot track you if you are using Brave browser.

About miners, nothing will happen. Keep on doing the good work 

blocking a certain port is going to only affect the newbie users who are using the defaults and don't know what else to do. otherwise the port 8333 is just a port, you can easily connect on another port. there currently are other nodes on other ports too which you can connect to.

however, your ISP can easily block your bitcoin traffic since none of it is encrypted and it can easily be read/sniffed. so all they have to do is to read your packets and if they are bitcoin-related they can block them.
if this becomes a thing, it again has a simple solution: adding a layer of encryption on top of it!

Dude, you didn't know how to use proxy?? I completed my graduation in 2006 and I have used proxy websites to access porns and orkut that time because these websites were blocked in my college.


No they can't. Please read the below discussion,

https://bitcoin.stackexchange.com/questions/18423/what-would-happen-to-the-bitcoin-network-if-all-isps-collectively-block-port-83

they cant because the nodes act as medium to the network while they send signals to the chain, and the network react to this so the miners are clean and safe to get this siginals and buld blocks on the chain ..


very simple dude*

In My country all ISP blocked many websites example porn is banned here.

Also when I was in University once they blocked uTorrent and no one was able to download and upload data.


So my question is it possible to stop full node and asic miner to stop accessing the network

What if they block port 8333 whatever BTc uses

I live in india
