Wayward ISPs Could Be A BGP Threat To The Bitcoin Blockchain Itself.steemCreated with Sketch.

The BGP Problem


The attacks on the Bitcoin blockchain are non-stop 24-7. Aviv Zohar and his colleagues at The Hebrew University, Israel have shown where to attack the Bitcoin cryptocurrency via its internet routing mechanism that it uses.

The Bitcoin devs have a problem, as they don't have a mechanism to protect the vector into the BGP (Border Gateway Protocol) that tell IP packets how they are routed across the backbone of the IP network.

Having worked in IT and telecoms myself, I know that BGP's problems are well documented. This was a protocol formulated in peaceful times before the arrival of cryptocurrency. It does for example trust the information is receives without questioning it whether it's from a rogue source or not??

If a wayward ISP suddenly decides to send incorrect BGP data into the network, then it's possible to 'black hole off' some of the internet traffic.

This full on attack would be a rude wakeup call because it would be completely undetectable. It's a well know fact that 50-60% of all the Bitcoin nodes reside with just 3-4 ISPs. Thus the probability of damage by a rogue employee is immense.

The big telcos know this and work hard to maintain the highest integrity of their staff but as we all know, if it can be man made, it can be man broken. This is indeed Bitcoins weakest link if there is such a thing.

Mine safely!

This is one of the worst things about how bitcoin has evolved. Satoshi saw the idea of people mining bitcoin if the price was too expensive. But, what has happened is that a few bitcoin miners have become giants and basically make it impossible for little guys to do anything (by themselves).

And so, centralization has happened in bitcoin. And that really isn't good.

Those whales get everywhere @builderofcastles - no crypto is immune from them eventually!

Well, it is by design. Bitcoin holds a lottery for who gets the bitcoin from all who mined blocks.
Instead of a system that pays every miner a little bit. Or a system that incrementally gets stronger with each miner added (not proof of work)

POW was Bitcoin's "Whales welcome here!" sign around its neck!
