Any way you can make sure that I'm on the invite list?  michaelmclees at gmail dot com?  I registered a while back but haven't got an invite.  And if I request and invite now I get an error.

But they avoided that issue. Interesting info though. So what's this further unexplained delay?

*yawn* Reported. Tired of all the trolling. We can't even have a conversation in here without you butting in and being a dick. Don't you have a job, a hobby or something?

I don't see how that message is trolling.  BFL claims to have taken a course of action that would avoid potential delay... and then pushed back the release another 4-6 weeks.  What gives?

There is another hot topic - multisig transactions for better wallet security.

What if litecoin implements BIP17 proposal? The bitcoin crowd seems to be slowly converging on BIP16.
There is a heated debate over here:
https://bitcointalk.org/index.php?topic=61125.0

This might bring some life and interest back into litecoin and it will truly compliment bitcoin by selecting a competing solution.
I think I have posted about it here a few days ago, but nobody seemed to pay attention.

Coblee, what do you think?

That's an interesting idea. I will look into it. Will need to weight the benefit of this versus the cost of having to maintain a separate codebase than Bitcoin. Unfortunately, there aren't that many people working on Litecoin (only me right now), so if BIP17 introduces a security hole, that might be disastrous. So I have to be careful there.

In the near future, I will merge in the latest bitcoin code and build a new Litecoin client. This will turn wallet encryption back on. Stay tuned.

If one wants to introduce a new feature, I would like to see this...  The ability to send an encrypted message to someone along with a transaction.  Is this possible?  Perhaps large messages could require fees.

Litecoin - You don't need a supercomputer to mine some!
Actually, a supercomputer would still be more useful to mine LTC than to mine BTC (you just need a GPU).

True, but I was implying that the multi-GPU setups we see around here are basically little compact supercomputers in themselves.
405  Bitcoin / Bitcoin Discussion / Re: Bitcoin transfer with Reference Field like in wire transfer forms on: January 27, 2012, 02:44:02 PM
Now, after having filled my target address B and amount of BTC in the "send" field of my client software, I am able to compose a message (=free text, like an SMS) and the client will encrypt this message with the public key of B (i.e. with the destination address) in the way that normally emails are encrypted with PGP public key mechanisms.

Bitcoin addresses are not public keys-- they are hashes of public keys (RIPE-MD-160 hash of the SHA256 hash of the public key, with a version number and checksum, to be annoyingly specific).

I agree that associating a message with a bitcoin transaction would be spiffy.



Raising this thread from the dead, because I think it would be a great feature.  Is this being worked on?  Is it feasible?  My thinking is that some people might want to make messaging a primary feature.

If someone wants to send only an encrypted message to a Bitcoin address, perhaps they pay per character or something, which would go towards fees for miners.  Sending a 140 character tweet for example, to a another Bitcoin client might involve sending a minimum transaction, plus the regular fee (if any), plus the message fee (.001 BTC/character) for example.

Something like....?

"Litecoin, the Silver to Bitcoin's Gold. Find out more here: (org address)"

"Litecoins, A Lighter Version of Bitcoin! Find out more here: (org address)"

or ??

Is there anywhere to spend Litecoins without first having to install closed source software?
They may be spent anywhere, including here.
If that was meant as an attempt at humor, I don't get it.
If it was meant as an intelligent response, it lacked useful information.
(Was your "here" supposed to be an actual link?)


There's a marketplace on this forum, but it isn't anonymous or decentralized like the Osirus forum.

Has anyone used litecoin somewhere besides an exchange? Are there any online merchants or services that use them?

I think the idea of a GPU-hostile coin is interesting, but it doesn't seem to actually do anything more or better than bitcoin can.

The only thing that is "nice" is the shorter block times so I can get my coins to an exchange faster and this isn't really what should be called an improvement.

Check the Litecoin Market link in my sig.  Also, someone on that forum has put up a bounty for a silk road tor site.  Who knows if it will ever happen or what the consequences would be.

How about you just untie yourself from MtGox.  You've become a dog wagging tail and while I personally find nothing wrong with it, so long as you advertise very clearly your lack of funds when people deposit money (rather than when they attempt to liquidate), if you want to make people here happy, you're going to need to operate more like a dark pool.

I received the same e-mail.  Phishing attempt.  Lucky Chrome caught it.

Click the Litecoin Market text in the first post.

how come when i copy over the new files i just keep getting longpoll detected a new block, but nothing else?

EDIT:  Nevermind, fixed it!

How?  I got the same error.
414  Alternate cryptocurrencies / Altcoin Discussion / Re: Anarchic p2p Litecoin Market Portal on: January 03, 2012, 03:14:47 PM
Having a Bitcoin Portal with a Litecoin section is one thing.  Having a dedicated Litecoin Portal with an emphasis on the marketplace is another.

Enormous increase!  Wonderful work again!
416  Alternate cryptocurrencies / Altcoin Discussion / Re: Anarchic p2p Litecoin Market Portal on: January 02, 2012, 10:17:05 PM
Excellent.  Remember, if you want to add categories to the forum or anything else, you're able to.

Litecoin Market

To use, you must download and install the free Osiris Serverless Portal System software.  http://www.osiris-sps.org/

When you have Osiris running in the background, click the Litecoin Market link above and join the portal.

The board is anarchic, meaning that there isn't a moderator or anyone else who can censor your posts without recourse.  The forum will take its shape on a reputation system, meaning users with high reputations will have their content confirmed by the system, while users with bad reputations will find their contributions naturally ousted.  Censors and attackers will naturally receive bad reputations and any changes they make will automatically revert back, or so this seems to be what Osiris is advertising.

Additionally, the system is anonymous, meaning that individual users can't be traced to individual IP addresses.  This is what Osiris is claiming.  I am not knowledgeable enough to know if this is actually the case.

We have Litecoins.  Let's see if we can get a market going where they might actually be worth something!
418  Alternate cryptocurrencies / Altcoin Discussion / Re: LTC miner optimizations for PowerPC (Power Mac) and Cell/BE (PlayStation 3) on: December 30, 2011, 01:28:02 AM
Do you think it would be possible to do a tutorial from start to finish for YouTube?
419  Alternate cryptocurrencies / Altcoin Discussion / Re: LTC miner optimizations for PowerPC (Power Mac) and Cell/BE (PlayStation 3) on: December 29, 2011, 10:34:38 PM
During the Christmas holidays I spent some time trying to figure out if PlayStation 3 is any good for Scrypt proof of work used by litecoin. As a result, LTC mining performance went up from ~1 khash/s to something like ~34 khash/s. My patches for jgarzik/ArtForz cpuminer are available at GitHub: https://github.com/ssvb/cpuminer

Everything should build fine in Linux using the standard "./autogen.sh && ./configure && make" steps (the availability of libspe2 library and spu-elf-gcc/embedspu tools should be detected automatically by configure). Setting CFLAGS to the optimal settings "-O3 -mcpu=cell -mtune=cell -maltivec -fstrict-aliasing" before compilation provides best performance. Note: this miner requires linux to run on PS3. If you don't have linux, you can't use it.

Also these optimizations should improve performance on many other PowerPC hardware by using Altivec instructions. If everything goes well, the PowerPC optimizations may be potentially merged with pooler's miner in the future.

If you find any bugs, please let me know. And sorry for a short announcement, I'll try to add more information later.

PS3 mines at 34khps?  That's quite a deal.  If there's an easy way to install the miner onto the PS3, there may be millions of new users out there.

When do you expect withdrawals to be up and running?  I've been mining for 2 weeks without a block and I'd like to make a withdrawal.
