181  Alternate cryptocurrencies / Altcoin Discussion / Re: [ANN] Official Litecoin shared domain litecoin.net on: August 04, 2012, 11:24:45 PM
I've setup a testnet explorer on http://explorer.testnet.litecoin.net/ http://testnet-explorer.litecoin.net/.

You can also add this domain to your testnet client with addnode to make sure you are always connected to an other testnet client. I have a few k/hashes working on testnet to generate blocks. I hope this helps others out when developing litecoin related applications.
It's down...

^^ This has been my worry for some time, a rogue client.
The team publishes PGP signatures for the binaries. Check those after downloading and you can be safe from this threat.

Oops. OK, I reported it.

Bumping this old thread because I noticed that I still have a wallet.dat.rewrite in my data directory, even though I'm now on 0.6.3...

What exactly does this file contain? If it's true that it contains unencrypted private keys, then it is quite dangerous to leave it lying around.

For some perspective, look at this graph comparing "bitcoin" to "dollar" and "euro":

http://www.google.com/trends/?q=bitcoin,dollar,euro

Bitcoin barely registers, even during the bubble.

Jest 8 places now and I wonder how "easy" would it be to change it?
I assume you meant "just," not "jest." Before making a statement, you could actually do the math and some thinking to come up with a sensible statement. Here, I'll do it for you. There will be a total of 21 million coins. With eight decimals on top of it, we have a total of 2.1E15 indivisible units of account. This is a big number, you know. To put it in perspective, the total of all gold ever mined in the history of humankind is about 150,000 tonnes, or 1.5E11 grams, or 1.5E14 mg of gold. Ever mined. There are fourteen times more bitcoin units than milligrams of gold ever mined. In current prices, one mg of gold is worth about four US cents.
I hope you'll agree that "just 8 places" is not a sensible comment.
Also, wondering how "easy" it would be to change the algorithm implies once again that you have already decided to be negative about something without doing proper research.
Oh snap! Grin

Bug report: Importing a paper wallet address (printed from bitaddress.org) with the built-in QR code reader doesn't work. Screenshot: http://imgur.com/h5Vo3

The private key shown in the error message is correct, so the Flash QR decoder seems to work.

I copy/pasted the private key from another QR decoder and it imported without problems.

191  Alternate cryptocurrencies / Altcoin Discussion / Re: BTC-e, LTC 0 confirmations 2 days later... on: July 31, 2012, 03:36:42 AM
OK - I obviously have something quite wrong with my wallet.

I have deleted all the block index files, db files etc from my Litecoin wallet area, and redownloaded the block index.

Abe.liteco.in is showing that the coins are in my wallet - as if I had never transferred them out, In fact it has 0 transfers out, and a total of 12 transactions. However the last entry in my wallet is showing the transfer out of 2825+ LTC to my BTC-E address, and still has 0 zero confirmations. My wallet is reporting 13 transactions so all is tallying up apart from the transfer to BTC-E. I have had mining income post the unconfirmed transaction.

Any ideas how I can "fix" my wallet?

Cheers


For some reason your transaction wasn't broadcast onto the net. This can happen with Bitcoin too, the only "fix" I know of is to leave the client running until it rebroadcasts the transaction. The coins are not shown in your local wallet because it has the transaction stored locally. Restoring a backup of course deletes the transaction.

Hi, looking for some advice,

A couple of days ago (July 28th) I sent 2825+ LTCs to my BTC-e account. However they have not arrived and my Litecoin-QT is reporting 0 confirmations.

They are obviously not available to my wallet, my BTC-e account is not showing the transactions and I am starting to get unsettled - this might not be a lot to some of you but represents a fair amount of fun had mining and some third party transactions.

I don't believe there is a blockchain.info for LTC, and I am wondering where on earth to start?

Cheers

That would only work if the attacker first announces his attack.
Couldn't you switch forks retroactively by placing a checkpoint on the fork you want? The blockchain database contains all blocks from all forks, right?
The block chain database contains only one(single) block chain not all blocks from all forks.
The Wiki disagrees: https://en.bitcoin.it/wiki/Block_chain

Blocks in shorter chains (or invalid chains) are called "orphan blocks", and while they are stored, they are not used for anything.

The sugar daddy would also have to dump the coins mined to keep the price below the point where it would be worthwhile to do a 51% attack.

Why would it ever be worthwhile to 51% a network. Is there some money to be made I am unaware of?

Transfer your coin to an exchange and convert it into dollars. Take your dollars spend them on hookers and beer. Replace the part of the chain that contains your transfer with your version of the blockchain that does not. Rinse and repeat.

https://en.bitcoin.it/wiki/Attacks#Attacker_has_a_lot_of_computing_power
...and then the exchange sets your dollar balance to a negative number and makes you return the money. Or you can never use that exchange again and hope they don't come after you.

And how do they know I submitted the false blockchain? Unless I am BCX and announce my intentions, nobody knows I am the one with the secret hash power.
All I did was accept BTC transfers from a third party and converted them to dollars. Half of the transactions look exactly the same as mine do.
They all got rolled back, so which transactions belong to the bad guy? It's not my fault the exchange lost their BTC.
It doesn't matter if you're a bad guy or an innocent bystander. When a blockchain fork happens, everyone that sold coins get them back.

Coblee, I wish you would sign releases with PGP/GnuPG, like the Bitcoin team does. It would give more assurance that these binaries are really authentic.
198  Bitcoin / Bitcoin Discussion / Re: Playing with Public Keys on: July 24, 2012, 04:06:14 AM

What would be the point of doing that instead of hashing the document to a private key? As you say, you'll destroy any coins sent there if you hash it to a public key.

If you just wanted proof-of-knowledge OR if you wanted to create a "black hole" that people could send BTC to, knowing those BTC could never be recovered until ECDSA was broken.

Hashing to a private key gives the same proof-of-knowledge, plus you can take your coin back.
199  Bitcoin / Bitcoin Discussion / Re: Playing with Public Keys on: July 24, 2012, 03:58:52 AM
Ah, I think you're missing a step in your code, namely the one that makes the public key out of the private key. This explains why I was not able to verify your calculation for "hello". Smiley

I used this site for the hash: http://www.xorbin.com/tools/sha256-hash-calculator
and then plugged the hex string as a private key into https://www.bitaddress.org/
which gives the Bitcoin address.

Nope, it works fine for me...

This code is public key only. You are not able to spend the money at the address, only generate the address itself.
