Topic: How IPv6 will destroy bitcoins (Read 2803 times)

IPvX is just an addressing protocol, doesn't add or diminish anything nor threats anything. IPv6 comes around because IPv4 range is depleted and more addresses are needed, nothing else.
The same "by country feature" exists in IPv4 as the public internet addresses are attributed to ISP's.

It won't - IPv6 makes no difference in the scope of things over IPv4.

When will IPv6 will destroy bitcoins

... again ...

How does the packet get to the IPv6 address?
Via a bunch of routers that have known locations.
Simple to determine where the IPv6 address is ...

Companies get netblocks (usually /32) allocated. They can be routed anywhere. I have a /48 starting with 2a01 registered to an american company being routed in Equinix Tokyo.

You don't need to announce the entire block in the same physical location.

Your argument requires more cowbell.

No it isn't. Not even close.

Yes, just as new currencies operating within a country are competition for that nation's currency.

Coz it's competition for them.
They lose on people using 'it instead of them' so they will try to destroy it since it's a 'new' idea that they can attack without any legal consequences.
Pretty standard for most businesses these days.
Even Microsoft got the idea from someone else ... namely IBM ... and they got it from ... not sure

It might be easier with IPv6, but it is easy enough now with IPv4. If a government wants to restrict Internet by country of IP address, they will do it. In fact, the decision to do so would probably be made by people who neither know nor care exactly how the filtering works on a technical level.

Some of you are missing my point, or I didn't explain it well.  IPv6 will make it MUCH easier to firewall based on location.  Yes, I know you can get geographical info of current IPv4 addresses now, but I'm saying with v6, it will be easier.  And like I also stated in my post, you will still be able to use VPN's/proxies/tunnels/tor to get around it.  My point was simply that the majority of people don't use vpn's or the like 24/7, including myself, even though I do have a really good VPN service which I pay for.  But I mostly use it for downloads, accessing one of my bank accounds, and watching HULU shows since it's blocked in Germany 

My guess is the whole controversy about bitcoin being an "evil hacker's currency to buy drugs" together with national economies around the world becoming more unstable and likely getting worse in the future, is only going to get the attention of governments, bad attention.  And I'm sure there will be governments that will try to put a stop to crypto currency.  Keyword being "try".

Just have a look at Paypal.  They already made it clear that they want nothing to do with the currency right off the bat.

Um ... a traceroute gives you the path from you to another IP - so in reality, IPv6 obscurity is, well, a myth.
You just need to know where the router 1 or 2 (or n) steps away from an IP address is to get a pretty good idea where the IP address itself is
(and pretty much about as accurate as determining where an IPv4 address is now)

I don't see how you can't just use tor or another proxy with bitcoin....

I generally find it doubtful that they will be able to enforce stronger "geographical" binding than already present, due to the fact that v6 addresses will be abundant and cheap if nothing else (I just bought meself a 12USD/year 128MB VPS for playing around with. It has ten v6 addresses "as a bonus" with the contract).

Also, keep in mind that Bitcoin only requires a trickle of a connection between two cut-off networks to remain synchronized. All it would take is one person to establish an outside connection, somehow. If it's only Bitcoin that's blocked, someone could make a node that encrypts it's connection to an outside node, or disguise the Bitcoin traffic as something else. If the entire internet is blocked, someone just needs a satellite connection (assuming those aren't blocked from connecting to other countries) or backdoor access to an international backbone router.

It mean NAT is no longer needed. You can still set one up if you need to for some reason, though, in my opinion, a better solution is just a home router that firewalls incoming connections. You'd just configure it with what ports you want open on what host, kind of like port forwarding, but where every host gets a unique public IP so that you can "forward" the same port for two hosts.

IPv6 means no more NAT?  I think a lot of people will still put networks behind NATing firewalls just for some 'security by obscurity'.   If IPv6 means everyone just plugs every server, workstation and device up to the internet directly, oh boy... going to be a lot of job security for network security experts

Marginally easier, I must say. A "standing on a sheet of rice paper" kind of advantage.

'walling "geo-foreign" traffic is easy already.

P.S.:
And who the living hell connects to bitcoin network w/o TOR anyways :p ?

Yea, not meaning to attack your post but essentially this is the only difference IPv6 will make ie: It will just be easier to firewall.

Good info toasty.  I wondered about companies that operated globally!  But I was told again and again at conferences that the subnets(or blocks) will be divided geographically.  Perhaps this was only meant to be divided when it came down to the registries.  But the speakers specifically mentioned how you will be able to tell where an IP is originating from (geographically) solely by the first few digits.

I'm sure this is the latest idea and the intention, (which I was not a fan of), and the ball is still rolling, so I guess time will tell.  I remember TONS of people registering for IPv6 subnet space back in 2002 or 2003, which they were given, only for it to be taken away less than a year later when plans started to change.  Even my organization was given a massive chunk because we operate in most countries worldwide, and have our own satellites to extend our networks, but it was taken away and redistributed, taken away, changed to another range etc etc.  We still have a massive chunk of address space, but who knows if it will change again...

In a way, the idea could have some advantages.  Such as finally being able to "google" something relevant that is in your own region (website, online shop etc) and not what gets the most hits (or fake hits).

I kinda don't like the fact that there will be less NATing, and hope that ISP's retain NATing, since I like the fact that I'm partially protected behind my modem, and my computers' IP's can't be DIRECTLY accessed from across the net.

As for the P2P design being able to reach anywhere as long as there's enough nodes, yes, that works, however, it won't work if all traffic is blocked at the "borderline" for that protocol.  It would essentially break up the single large worldwide P2P network, into smaller independent P2P networks of the same breed that can't talk to eachother anymore.  And it could be done if a government or agency thought it was important enough to do, just look at the great firewall of China... 

If what I've heard at the conferences happens, IPv6 will only make this even easier for everyone to do.
