Topic: Alternative Block Chains : be safe! - page 76. (Read 1363924 times)
According to me we should first have a detail study of other alternative blokchains and then select the write one.I am a Newbie, we may use different virtual machines.We should first know whether it is a scam or it is a right thing before spending money and time on it.
Blockchain is hosted by billions of computers around the world so that it is not controlled by any single person. Each process in the blockchain network owns a full copy of every transaction or movement of the data on the blockchain, it mean that the details and history of the transaction are traced.Despite historically being used to handle financial transactions, the security and reliability of blockchain technology means that it can be applied to other areas and industries. I thinkt there are three benefits that blockchain technology can provide are: (1)The increase in security and trust. (2) Reduced costs. (3)Accelerated transactions.
Question to the author. We all here have read your message. Did I understand correctly that we are talking about the fact that bitcoin is helpless against hacker attacks? Or he does not stand up to criticism, if we say that his endless chain is preparing his death? Bitcoin also reminds me of the old computer game of Snake. This is when you have a small snake moving around the screen, consisting of characters and passing through the characters it grows its tail, until she herself does not sting it for him? But, this does not prevent people from earning on bitcoins. Then why fool yourself?
indeed there is an overgrowing fear especially on Bitcoin like for example the double spent move but for me the biggest fear is from the so called cryptocurrency regulations. 
It is hard to keep up with the speed of regulation change, and also with the number of ICOs
it depends on the project not ICO
so what happens if you only use one computer system?
Helpful, thanks. But if I don't use virtual machine it really risky? If it is, how to use it?
I'm a newbie, but as far as I know you need to downoload specific soft (like VirtualBox. It's free, by the way). And then you get your own new HDD)Maybe this article will be helpful: https://www.howtogeek.com/196060/beginner-geek-how-to-create-and-use-virtual-machines/
Helpful, thanks. But if I don't use virtual machine it really risky? If it is, how to use it?
Thank you for your advice..
Actually right now I am considering investing on RISE so I am researching and looking more into it...thanks

I've heard about RISE but didn't understand if it's really worth. What do you know?
Thanks Gavin, really helpful information and I would like to add people must have a knowledge what a blockchain actually is and it would help them alot to cope with many issues.

Helpful source. There are many people around me having any idea about blockchain technology but they use most of they money for investment. Having information is a must before investing.

Thanks for a wonderfully composed explanatory video... super informative

Definitely both issues, though personally I'd focus more on distilling the bad (and the really bad) from the good, since a. regulations aren't necessarily predictable or within our control, and b. there's so much out there, and so much of it is horrendous.

Good advice so as not to get caught by scammers who will use your pc's resources.

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.

a very realistic detection. I agree with your thoughts. Investing is a crazy investment.

Far from being an unprecedented breakthrough, with unintended consequences, the blockchain technology stack is a culmination of decades of cryptography and security research.
The 1970s cryptography breakthrough of the Merkle tree and the distributed hash tables of the 1990s combine to create autonomy, fault tolerance and scalability for distributed systems. They're the tools that built famous decentralised applications like BitTorrent, Napster and Freenet.Bitcoin's most impressive contribution is recognising the synergies between this field of distributed communications and file sharing systems, and digital currencies, which had seen many false starts prior to Bitcoin's success since 2009.
The key was Hashcash, a system proposed in 1997 to limit and suppress email spam and denial-of-service attacks. Hashcash is an algorithm that requires the sacrifice of processing power as a security mechanism. This proof-of-work creates the incentive structure and network verification that now powers cryptocurrencies.
The final step is the addition of smart contracts to the blockchain stack, a name coined by Nick Szabo as early as 1993. Smart contracts are algorithmic; a type of self-executing code which enables more complex asset transfer and the automated exchange of rights. These are the building blocks of a complete programming language, and the more advanced blockchain applications such as those envisioned by Ethereum.
What we get is a set of security tools that are very good at coordination between mutually unknown actors and secure data or value transfer. We think of blockchains as having four key characteristics to this end: they're cryptography-based, distributed, peer to peer, and, in many cases, open source.
