Re: [ANN] POPULOUS - Invoice trading platform | ICO l BOUNTY CAMPAIGN

on 09/07/2018, 11:20:52 UTC
I've been trying to get verified for weeks now and I can't even get a comment on my profile about what else they need or if something posted isn't right. I get that they're coding and getting the next batches of invoices ready but I need this finalized so I can get an address and load my ppt on there so I can get in on the next round of contracts. Obviously, ppt's price in btc (and consequently usd) is starting to go as we get closer to these newer invoices being listed. The selling pressure is gone at this point, up we go.

Glad I'm not the only one. It's been three months since my first attempt at being verified - this just fell off their systems. I tried again and it's been sitting there waiting to be verified for over two months. Pathetic. I was really looking forward to getting in on the invoice buying action...

A NAME for the coin. Just an idea which I posted on Reddit:

Hi people,

To me this seems a fairly obvious idea - there needs to be a simple name for the "electroneum coin". And the two clearest candidates are "sparks" and "flashes". Sorry if this has already been proposed.

I'm going to relate an anecdote and you'll see how this naming convention cuts out about 1000 syllables of wasted breath.

After the ICO I decided that I loved this coin so much that I bought about 5000 extra sparks at 0.03 cents per spark. I had them sitting on Cryptopia in the lead up to the relaunch.

When the sparks hit 17c a few hours before relaunch I realized that people were going to ground the sparks (physics joke) down upon receiving their pre-ico tokens so I sold a small tranche for 0.5 LTC and waited in anticipation of the relaunch. When the relaunch occurred, sparks were truly flying (hehe), so I sold my 0.5 LTC for a profit of 800 zappy sparks. I felt very smug about this, knowing that it wouldn't be long before lightning would strike and a spark would strike the beloved $1 mark. Pretty soon we'll all be dealing in flashes, as a spark will be way too powerful and valuable.

You could also use the verb "zap". For example: "Please zap me 5 sparks." LOL

If you don't like my idea, then read out the above with the term "Electroneum token."

If you do like my idea, please zap me as much as you like:

Yeah, I saw these and they look like great ideas. Unfortunately, they're just ideas at the moment! LOL.

That's a really good idea , I would like to know also if there is any decentralized email provider !

After quick search I found CryptaMail, FlowingMail and Proemtheus (ICO).
Anybody used any of this emails?

Hi people,

I'm wondering if anyone knows of a good alternative to Gmail. I have come to detest a lot of what Google stands for and would like to move to a different email provider. Are there any good decentralized email services or ones that don't want to know everything about you?

Any advice appreciated.

Re: Vanity wallets on bitaddress.org/ compressed addresses on directory.io

So each private key can ultimately produce two different addresses - one compressed and one uncompressed? And different private keys can produce the same address (i.e. there are 2^96 private keys for each address)?

From the web:
"A compressed key is just a way of storing a public key in fewer bytes (33 instead of 65). There are no compatibility or security issues because they are precisely the same keys, just stored in a different way. "

So they're the same keys but when hashed produce different addresses?

Re: Matching public key with directory.io - why so difficult?

on 05/10/2017, 06:11:42 UTC
Wow! Thanks heaps.

At the very first moment when you visit directory.io to find the page number of your offline created private key, it will be very easy for the admin of the page to steal your funds immediately PLUS your offline generated key is not offline anymore. There is no need to repeat the visit, because the attacker (admin) can simply check all visited directory.io pages and check the balance of all private keys on that very page.

You obviously didn't read my posts! I was thinking about USING directory.io as an offline wallet generator - IF I could get the code offline. Unfortunately, the creator hasn't made the code downloadable.



No?

Thanks achow101. I'll check out vanitygen.

Regarding compressed/ uncompressed addresses, why does directory.io list compressed addresses next to uncompressed ones? When you create a compressed address is this in fact a new address from the 2^160 pool of public keys? Confused...

Vanity wallets on bitaddress.org/ compressed addresses on directory.io

⭐ Merited by ETFbitcoin (1)
Hi everyone,

1) I was interested in creating a vanity wallet on bitaddress.org, but it points me to the vanity pool website to paste my public key and there's no field to do so. Is the vanity pool website defunct?

2) On directory.io, why do addresses and their corresponding compressed addresses show different transaction information on blockchain.info? Aren't they essentially the same address?

Thanks for any help,

Ag

If you will visit https://litecoin.org/#download you will see Electrum Litecoin there listed with other supported wallets. Maybe it's your eyesight indeed or you missed checking the download page. I don't have a personal experience since I am not holding LTC but I've seen several positive reviews and recommendations about it here in the forum.

Some reviews and recommendations:

Hi everyone,

I want to use Electrum for LTC, but I want to make sure that:

- it is approved and trusted by the LTC community
- that there's a page on litecoin.org that lists it as a wallet option, with corresponding link

All I can really find is a listing on duckduckgo.com or forum posts saying that it's ok. I'm not convinced!

It would also be good if there was a page on litecoin.org that listed ALL the trustworthy wallet options available. Am I missing something? (I have poor eyes, so this is a possibility.)

Re: Do you still support Ethereum?

It is the incumbent in its particular crypto niche and will probably be difficult to dislodge. If EOS can be all it aims to be then ETH might be in for a battle, but EOS has a terribly lengthy path towards fruition of its goals. I threw a very small amount of money into EOS because I think it has a slim chance of being an ETH killer. With all the support that ETH has I think that it's probably going to be here for the long-term. I forecast $1000 ETH by the end of this year.

I don't understand why you are so fixated on choosing your own private key that is memorable. Why not instead generate random private keys until you generate something that you find memorable. That is far more secure than you choosing something memorable.

These are just ideas and this is just a discussion. I'm the type of person that delves and delves until I find myself answering other people's questions on whatever it is I'm investigating.

A random private key will never be as memorable to me as something I create myself. So there's a trade-off either way you go.

It can be stolen the moment you decide to spend the coins and have to enter you private key into some software. Even if you are keeping the coins in long term storage, at some point in the future you will want to move those coins out of storage to do something with them. Whenever you do that, you expose your private key and it can be stolen.

Similarly, the same argument can be made for randomly generating a private key and keeping it on a storage medium that never touches the internet.

There is also still a significant privacy loss even if you are only using that address for receiving. For starters, everyone that sends you money will know how much money you have. Furthermore you are reducing the privacy of everyone that transacts with you because anyone will be able to look at their transactions and immediately know who they were paying and how much.

Once again, you're assuming I'm reusing this public address over-and-over again or that I'm advertising it. This is my storage wallet and not an address for people to send me funds. True, if I bring them out of hibernation it increases their vulnerability. Then I go down the path of p2p wallets, etc and find a new cold address to send my savings to.

Thanks for your detailed response. I'm sure others will find it useful too.


>>>>First of all, you are essentially sending your private key to a remote web server (directory.io).

Not if I'm doing the public-private key generation locally on an air-gapped, unconnected computer - one of the reasons for my posts above. I would like to get hold of that code for personal use, but the creator has hidden it, unlike other websites that randomly generate public-private key pairs. I actually think that I could create the code if I really put my mind to it, something I might consider if I can't get that code.

>>>>Secondly, you still need to load that private key into a wallet software in order to spend from it.

Not if I'm keeping it purely for storage and not transacting with it.

>>>>Thirdly, because the private key is in an unencrypted form, if the private key is stolen, then the thief can spend your coins immediately. With wallet encryption, if your coins are stolen, you still have time to move them as strong encryption and a strong password will protect your private keys.

How would a thief steal it if it's committed to memory and the public key has only ever been used once - to deposit the money? You're assuming I'm using it for transacting. That wallet is cold and the private key has never touched the Internet.

>>>>Lastly, you would be reusing the exact same address over and over again which will lead to significant privacy loss.

Not if I simply put the bitcoin there for long term storage.
-----------------------

The more I think about it, the better my idea becomes - for storage purposes, that is. Perhaps not for transacting.

OK, this makes a bit more sense now. My "algorithm" for determining the key to use would make it more vulnerable to attack than a randomly generated key. But I still have an issue with this and it would be a really interesting study.

What's the greater risk?:

1) Using my method where it's a simple algorithm for me to remember the page number and location via a HUGE (and I mean HUGE) string of numbers - i.e. not your typical internet password. This wallet would exist in my head. Despite this, it's more vulnerable to attack because it doesn't have the entropy of a purely randomly generated number.

2) Using a randomly generated key which is less prone to attack, but is more easily forgotten or the details of which more easily lost. (This key would have to be stored somewhere physical, opening it up to being attacked in a way the first option wouldn't.)

I wonder what the figures are in terms of dollar value lost due to i) hacking ii) simply losing your private key.

I've already spoken to one guy who lost over 1000 bitcoin on a hard drive somewhere, and I bet most of you have heard similar stories. I would almost hazard that simple user clumsiness (i.e. option ii) is a greater threat to your wealth than being hacked.

I actually don't see why it's so terrible if I do it offline, air-gapped? Doesn't this directory list ALL potential private keys? It's not as if I'd use page 235 key 15 as my address...my choice would be far more sophisticated than that.
Using directory.io to choose your private key is a horrible idea, regardless of whether you are online or offline. Private keys are only secure if they are randomly generated using a cryptographically secure random number generator. By using directory.io (or any other list of private keys) to select your private keys manually, you are significantly reducing your security because humans are notoriously bad at securely generating random numbers. You as a human do not provide enough entropy to actually choose a random number randomly, which means that whatever private key you choose will be insecure and more likely to be easily brute forced.

I love this stuff! Thanks. I've seen the puzzle transaction - that's cool.

FYI:  The first 54970.38 billion pages on directory.io have already been searched for active Bitcoins and a few were found.  Most if not all of the bitcoins found in these first 54970.38 billion pages were placed there on purpose as a sort of "canary in a coal mine" test of the security of the network.

See the search project (started at private key 0 and searching the private key space linearly, currently running about 21.10 trillion keys per day):

I've been thinking a bit and to me this site could be the perfect cold wallet generator. It gives you a means of choosing an address to store your bitcoin which would be very easy to look up. You remember by page number and location on the page, rather than by address. It means you CHOOSE your address rather than in the case of those other sites which choose one for you at random.

I would like to be able to use this page offline on an air-gapped computer, but the code has been hidden and it's only possible to use online. Is there a way of getting it offline?

Thanks,

Its an absolutely terrible idea. Humans SHOULD NOT be allowed to choose their own private key from a pool of addresses. The level of security you can expect from an address in directory.io should be considered as insecure as brainwallet generated from key phrase "correct battery horse staple". The problem with you picking an address that is already generated means that anyone else would have a decent chance (higher chance than someone generating a conflicting address) of finding your address and the corresponding private key. Needless to say, the database can be modified or removed at any time. Most clients generates addresses securely and it is never an issue.

Tl;Dr: It is an extremely bad idea and its stupid for anyone to use an address listed there.
