1  Alternate cryptocurrencies / Announcements (Altcoins) / Re: ⋆⋆⋆ [SDC] ShadowCash | ShadowSend v2 IS ALIVE ! ** MANDATORY WALLET UPGRADE! ⋆⋆⋆ on: December 26, 2014, 07:49:59 PM
Guys/Gals, can we please please stop getting carried away with this shadow and cryptonote...  Shadow is not based on cryptonote and does not function like cryptonote!

Thanks

Oops. Sorry.
smooth an I had a convo based on the assumption Shadow (ssv2) was based on cryptonote! He read the whitepaper and somehow was under the impression it was. How ddi this confusion begin?

Please tell us what it is if not based on cryptonote! Is it somehow an improvement?!

EDIT: Cryptonote 2.0 is cited in the references, altho I cannot see where the reference appears in the paper.

I have a question about shadow-to-shadow transactions.

0) I own 0 shadow.

1) Person A sends me 1 shadow.

2) I then myself 1 shadow. (not sure if this step is needed).

3) I send A some of the shadow back, say 0.9.

Question: Is it possible for A using some offline techniques in the (far enough) future to tell this 0.9 shadow is mine with a high probability? Probably this depends on the number of transactions of the network and number of users. So if you answer this question feel free to go into this as well.

I know for instance that, as things are right now, with Monero this fails, i.e. person A can tell the money comes from me with a high probability.

Thank you.

EDIT: New post with corrected conditions: https://bitcointalk.org/index.php?topic=903319.0

Hello,

I am looking for private keys of addresses that used to contain newly mined coins.

The addresses should be at least from 2013 or earlier.

Offer:
1 BTC per address used to contain 50 BTC
0.5 BTC per address used to contain 25 BTC

Escrow is welcome.

This is an open discussion, so your thoughts more than welcome.

Here is what i think that happened:

"A few people with a lot of money, a few brilliant ideas and the will to fuck everyone up in order to make loads more money came up with a great idea: let's create digital money, some bullshit about fighting banks, some japanese guy that doesn't really exist, silkroad for a bit.
Let's give this Bitcoin thing value by pumping the hell out of it, and let it drop on  a bunch of unwanted childs that dream of getting rich with this shit.
In the Meantime we will have an organized ring of scammers ( Karpelles, cryptorush, mintpal.. etc etc .. ) that will make us even richer.
We will also have another organized ring of scammers/devs that will create new coins so we can pump and dump the hell out of them to make even more and more money.
Once this shit gets regulated we will just leave with more billions and see ya"







Bitcoin is a pump and dump just like gold is. This says it all.

[...] some of which have been tracked as entering your exchange through the Bitcoin transaction: 9c0824176a642f4e4542cd6438ae689f6d9d843532ee8c3aba3f4d105bcf3b86

Excuse my ignorance, but how is it possible to check if an address belongs to bitstamp or not?
How can this guy tell the recipient's address belongs to bitstamp and not to another service?

Yes, it's definitely an issue. It slows down the syncing terribly.

You get all those orphaned blocks when they get sent to you in parallel by the peers you're connected to (that's what I read and I still don't really get what's going on).

Apparently it's been fixed and it will make it into 0.9.3.

But if you can't wait here's how I went around it. Just launch bitcoind with -maxconnections=3.
Since the parallelism is lower this reduces the amount of orphans dramatically. I find the speed still pretty good with 3 connections.

After you're done with the syncing, leave out this parameter cause the more connections you have the better. There shouldn't be orphans after the syncing.

Hope it helps.
7  Bitcoin / Bitcoin Technical Support / ProcessBlock: ORPHAN BLOCK in debug.log – Meaning? on: August 19, 2014, 07:09:02 PM
In my debug.log I see a lot of the following messages (with different orphan block number):

2014-08-19 19:04:23 ProcessBlock: ORPHAN BLOCK 631, prev=00000000000000005ee64e8321c3c428a91f5acc60b3ee02eaf1159c68e7e95b

It even blocked the sync of my bitcoind for several hours until I manually restarted it.

I've found this thread about it, and it seems to be a real issue/bug: https://github.com/bitcoin/bitcoin/issues/4353

However, I don't really understand exactly what the problem is and if there is something I can do about it.

The bitcoind was running on a Mac Mini 2.3Ghz i7, 4GB RAM, 1TB HD. It was run after a fresh reboot and most of the HD is free.

Does anybody know what's going on there?

Edit: Actually, I just noticed the orphan block number is now always 751. It looks like it reached like a sort of maximum value.
8  Bitcoin / Bitcoin Technical Support / How long does it take for bitcoind to sync nowadays? on: August 19, 2014, 12:16:35 PM
I let it run on a Mac mini i7 with HD (not SSD) for 14.5 hours using bootstrap.dat and the txindex=1 in bitcoin.conf. I'm now at block 277'000 (December 26th 2013). It's slowing down like crazy.

Anybody care to share their timings? Thx!

EDIT: The sync is over. It took me 23 hours with Bootstrap.dat and txindex=1. Be careful if you're using the 0.9.2.1 version. You can fix a bug that slows down the syncing here: https://bitcointalk.org/index.php?topic=746840.0
9  Bitcoin / Meetups / Am in SF for 1 month, wanna build the best iPhone wallet? on: June 04, 2014, 08:05:21 PM
I'm a senior senior iOS developer and I'm visiting San Francisco for 1 month.
Any kick-ass designers or other iOS developers out there that might want to meet up to discuss and possibly start a Bitcoin iPhone wallet together?

Looking forward!

This is really, really cool.

Congrats!

I was wondering if the fraud detection system of banks would turn on since you're using the card all over the world. Probably this won't happen cause, as you said, they think the card is inserted physically?

How can a person get coins if there is no mining?
Who gives them away?
How are they created?



The inflation is capped at 2% per year. It will only be used to fund projects that increase the value of Skycoin.
[...]
So if used correctly, the inflation will cause deflation, not inflation in the Skycoin price.
 

- I start with the belief that any kind of inflation will eventually turn into a tax.

- It might be true that, in the beginning, projects funded with the inflation tax will help skycoin to increase its market cap (still not convinced about this...). But in the longer run, when the market cap is already at its maximum, there won't be space for growth anymore: you simply cannot grow forever! There is a limit to growth. At that point we'll have a forced freaking 2% tax. Maybe only 0.01% will be needed to polish skycoin at that point, however we'll be wasting 2%.
This will give rise to a new elite of people working at skycoin with money from tax payers. They'll be the new central bank and government.

A free market with competition and 0 taxes is better than this inflation tax.
12  Alternate cryptocurrencies / Altcoin Discussion / Skycoin on: December 23, 2013, 06:27:11 PM
Does anybody know how coins are generated with Skycoin?
I'm still a "newbie" and can't directly post to the thread I was following..
