However, blockchains of the future (or networks that will replace blockchain) are still yet to come. Many restrictions of current blockchains need to be overcome to scale efficiently.

Bitcoin and all kind of money blockchains are risky things in some extent. Risk one of the business feature.
If you want wipe out all risks of your life then do nothing. Blockchains are not scam, it work. But you must to be competent in the questions of security.

QuickX : QUICKEST CROSS BLOCKCHAIN TRANSACTIONS

Some people only have one computer and that must suck. Fortunately I have multiple so I can use some of my alt-miners to do this safely.

People with only one computer can still securely isolate different wallets & apps from each other by using privilege separation. For example on Linux, run bitcoin/namecoin/i0coin/etc under separate user accounts, and chmod 700 their home directories.

And what about Windows or Mac?

That's a very good insight indeed! I also believe that one must thoroughly check the scalability issues of any Alt-Block chain before investing any large amount. Smiley

I haven't seen anybody post about what would be my biggest worry if I were trying out alternative block chains. I realize this may be perceived as "Gavin is FUD'ding anything that isn't bitcoin!"  (FUD == Fear, Uncertainty and Doubt)  But I think some of you might be forgetting some basic computer security fundamentals in the excitement to be early adopters.

When I first heard about bitcoin, my questions were:

1) Can it possibly work (do the ideas for how it works make sense)?
2) Is it a scam?
3) If it is not a scam, could it open my computer up to viruses/trojans if I run it?

I answered those questions by:

1) Reading and understanding Satoshi's whitepaper.  Then thinking about it for a day or two and reading it again.
2) Finding out everything I could about the project.  I read every forum thread here (there were probably under a hundred threads back then) and read Satoshi's initial postings on the crypto mailing list.
3) Downloaded and skimmed the source code to see if it looked vulnerable to buffer overflow or other remotely exploitable attacks.

If I were going to experiment with an alternative block-chain, I'd go through the same process again. But I'm an old conservative fuddy-duddy.

If you want to take a risk on a brand-new alternative block-chain, I'd strongly suggest that you:

1) Run the software in a virtual machine or on a machine that doesn't contain anything valuable.
2) Don't invest more money or time than you can afford to lose.
3) Use a different passphrase at every exchange site.


in my personal opinion
It's hard enough to get the half-baked alt chain software to run at all (and speed is of the essence knowing they are all quickly collapsing pyramids) never mind configuring a VM with appropriate hardware access. 
> Don't use Windows and pre-built .exes.  Just don't.  Ever.  Nothing inherently wrong with Microsoft software, but it is well understood and commonly used by the botnet types.
> Create a new account with no group membership.  I call mine "goatse" for obvious but nostalgic reasons.  Make absolutely sure that account doesn't have read or write access outside of their home directory.
> Log out of your main account and into that account whenever compiling or running the alt chain software.  Remember that compilation & installation scripts are code!
> Do not browse exchange sites you have coinage in and definitely do not save passwords in the browser when logged in as this account.
> If you log into this account via ssh DO NOT enable X proxying.  It's trivial to read your keystrokes, do screen captures, etc when X is proxied.  Let me repeat this one, make sure X proxying is disabled.
And yes, I even follow this for official bitcoin software.

Generally, if you have a large amount of bitcoins on a given PC, being extra-cautious about third party software (be it an Alt-coin client or a particularly fancy casual game) is advisable.

Although I don't think the fiasco with Namecoin is over and I do believe we have made it hard for BitcoinExpress.  With that said I looked into the block chain rewrite this is real and can be done while lagitamitly mining bitcoins.  This exploit is quite scary for Bitcoins as a person with 20% of the hash rate can write the block chain.

Security is the basic concept on the block chain. Unless and until we have a clear satisfaction of the security we should not invest huge amount. What you mentioned all agreed and we have to agreed also the whole life is full of risk only without risk we cant live. So Alternative block chains are safe except some unsecured.

Thank you so much for the warning(s). Good to light this up... I’m sure that some people didn’t realise these things before.

I think that everything has been checked long ago, since there is a lot of money in this business, and those who tested have a very large experience. So there's no need to worry about this yet.

Huge amount of currencies exist without any particular sense. Their investment potential is very low. But they can still be valuable for collections or for promotion cryptocurrency idea in society, something like advertisement. 
So this is not a holy trash as somebody have told.

Thank you for the advice.
Altering password is already doing.
This made me to think more about new blockchains emerging frequently.

I myself personally continue to be surprised that some currencies are growing and good ones are falling, since the bad ones (as I call them) are greatly overpriced. And crypts with low quality are now used mainly for manipulations no more.

Blokchains Within popular media, the prototypical system used to explain blockchain is the bitcoin network. But this is just one type of solution in this space. It is useful to think of three main types of blockchain, or “distributedledger” Blockchain exists at the cross-over between economics and technology. To apply it effectively, we need to understand both sides of its personality. The economics of a system will affect the technical design and vice versa..
