There's a new block every X minutes. Where's the exponential growth?

I think you're being too literal. I'm not the person you replied to but I've also wondered how the unbounded growth is sustainable.

Moore's Law/Kryder's Law ... advancement in technology outpaces growth.

This is exactly the right mindset to build great software that is totally unable to run on modest hardware.

Doesn't that mean that a whole blockchain could possibly be deemed illegal in some country due to copyright infringement or other liability of publications laws? I mean if you can't erase the data and keep publishing it, some would say you are liable. I see that as a particularly twisted legal argument, but couldn't some country use that against blockchain infrastructure if they feel like it?

Yes, this is indeed one possible attack vector! For more information, please see: https://en.bitcoin.it/wiki/Weaknesses#Illegal_content_in_the... To quote: It is illegal in some countries to possess/distribute certain kinds of data. Since arbitrary data can be included in Bitcoin transactions, and full Bitcoin nodes must normally have a copy of all unspent transactions, this could cause legal problems. However, Local…

All the content on http://dogeyip.com/ is pulled from data encoded into UTXO on the dogecoin blockchain. If you're clever you can encode as much data as you want into any block chain using this technique. Obviously, the techniques used here can also be used on the bitcoin blockchain.

Example: All the text for the blog posts here are pulled via api from data encoded into UTXOs in the dogecoin blockchain: http://dogeyip.com/blog.html

A map to find treasure or secret passwords or the end of the world plans...Just imagine what could end up in the blockchain. Part time capsule part safe part invisible ink part James bond part infinity. Just think of all the craziness..I need to put something in the blockchain. But what...

Or my favorite: stamp.io

If you have an Estonian ID, Stamp.io lets you sign it too!

Full disclosure: I know the Stamp.io team, and they're awesome.

Interesting twist if bitcoin blockchain would be found to distribute illegal porn or private/secret/classified data(it already stores some wikileaks content). # How does government stop/censor a global p2p network? I guess they would put pressure on developers and bitcoin foundation to remove the offending data and update the (official) software to block/reject/deny any upload of it. I assume it would have to employ…

Interestingly, it would be very difficult to censor compressed data that is stored in Bitcoin addresses and impossible to censor encrypted data that is stored there.

I mean... its happened before and you had no idea

Its still in bitcoin's blockchain. There's lots of stuff in there.

Only if Moore's law turns out to be false.

A hundred years from now, you could store the blockchain on current day hardware. And that is without talking about improvements in technology.

Sorry if I'm naive but another thing I've always wondered about that is the exponential size of the blockchain. I mean if Bitcoin ever gain real traction isn't it pretty inefficient to store all the data and replicate it around? Storage now seem infinite but practicality it is not, won't current blockchain be saturated to the point of uselessness when/if it reach usage level of an actual banking network? "Let think a…

There's a new block every X minutes. Where's the exponential growth?

Also found out this graph: https://blockchain.info/charts/blocks-size?timespan=all

This is definitely not linear, and keep it mind it's only with a small amount of early adopter that they reached 125 Go mark.

As a matter of comparaison the whole database of the earth map at openstreetmap.org is as of writing only 36 Go fat when delivered in compressed form. https://planet.openstreetmap.org/pbf/

It seems absolutely ridiculous and a waste of ressource to expect that the blockchain shall never/ever use some rotating process to loose weight at some point.

Blockchain like technology can be very usefull, but current implementation look like a very rotten seed. And if a newer version that solve those issue emerge why on earth would they want to give any value to a prototype currency driven by opportunistics "first in" miners?

I desperately hope that no public fund was stupid enough to invest any real life saving to this mess because IMHO it's not a matter of if, but a matter of when it will collapse.
