I think I found a way to recover my spreadcoins but you may not like it.

As I lost my wallet.dat I don't know exactly what blocks I mined and exactly how many coins I had.
I can approximately determine block before which my lost coins are situated. Everyone who have mined coins before this block will send them to him/herself (this can be made automatic). This will mean that this coins are not mine. Then, using some hack and releasing a new client I can send myself amount of the rest coins (or maybe less, say 80%).

This rasises two concerns:
1. What if someone will forgot to send coins to him/herself? These coins will still be spendable so he/she will not lost them. This raises the second concern:
2. What if I am a scammer and want just to double my coins, keeping old ones and getting new ones? The only way to prevent this that I see is to limit the percentage of presumably lost coins that can be spend but this is not trivial.

What do you think about such a plan? Is it acceptable in you opinion?

P.S. This way there is no need for anyone to donate coins to me.

Bad news  Sad
I was too careless and lost all my mined spreadcoins. I contacted several data recovery companies and most probably it will be impossible to recover my wallet. Without these spreadcoins I will have no incentive to futher develop and support SpreadCoin.

Sorry for wasting your time with this cryptocurrency Sad

I tried to make a website, I redid it several times but it only became worser every time Smiley. Surely, making websites is not my strongest point.
I hope in the future someone will help us to make a better website, current version is pretty empty, there is just a page with current features.

I promised to release a cool update "in several days". Well, it will take some more time, sorry for this delay.
344  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] SpreadCoin on: August 24, 2014, 01:09:35 AM
Added to op

Is this still active???

Mr, Spread - you here? I want to make my first installment payment for the bet I lost...
Yes, I'm here
345  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] SpreadCoin on: August 20, 2014, 10:13:35 PM
There will be announcement soon (in several days I hope). I just need to implement everything right and write whitepaper.
This will take somewhat more time; I was quite busy in real life.

Manwhile I added more info to OP about current features of SpreadCoin: transactions in SpreadCoin are smaller than in Bitcoin. Although it was known for a long time that digital signatures in Bitcoin are space-inefficent I don't know about any other Bitcoin fork that cared to fix them.
Compact Transactions
SpreadCoin uses more compact representation for signatures in transactions. This leads to smaller transactions and, hence, smaller blockchain. See e.g. this transaction in SpreadCoin and similar transaction in Bitcoin, both transactions have 15 inputs and 1 output but SpreadCoin transaction takes 1661 bytes while Bitcoin one takes 2744.
See this thread for more info: https://bitcointalk.org/?topic=6430.0%29%3F

Also there is a Linux build for those who don't want to build it themselves.
346  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] SpreadCoin on: August 17, 2014, 02:59:08 PM
block zero has 1 SPR generated, but
Block 0 reward is not spendable, so it doesn't actually matter, I just set it to 1.

each of the next 2201 blocks has approx 66.66---- SPR generated.
The first blocks runs really fast, with high reward.

Mining began a few seconds earlier from 2014-07-29 11:01:16 when the first block was generated,
then first 200 blocks run with incredible speed just during less than 15 minutes.  2014-07-29 11:14:47 (diff 0.0016)
The next 200 blocks were created until 2014-07-29 12:05:58. (diff 0.0693)
only then the generation speed started to slow gradually.
so during first hour there was minted 26,666 coins.
Block 600 was generated much later, on 2014-07-31 at 03:58:26.

Until the fork at block 2202 there was minted approx 146,750 coins.
When taken as a whole, the number of coins minted in first 2201 blocks before the hard fork was done, the coin almost fits the specs -
2201 blocks between 2014-07-29 11:01:16 and 2014-08-11 18:03:03, which was 319 hours, 1 minute and 47 seconds, it should be around 1915 blocks.
Difficulty was very low at launch and I saw somethig like 25-30 connections right after the launch, I don't know how many peers there actually were and how many of them were mining.

But, somebody took great advantage until difficulty algorithm sets it right, and then, miners who joined later, were penalized, because the coin generation was slowered more, to compensate the initial speedup.

I am not trying to offend anyone here, as I do not know if it is even possible to avoid these initial fluctuations. I am just sharing what I have found.
Initially, it seems to me like (not so big) instamine, but with all these numbers the dev seems fair to me.
Yeah, at least this is not Darkcoin instamine where they mined first 575 blocks in 15 minutes with reward 100x higher than current: https://chainz.cryptoid.info/drk/block.dws?000007d91d1254d60e2dd1ae580383070a4ddffa4c64c2eeb4a2f9ecc0414343.htm

What are the next plans with the coin?
There will be announcement soon (in several days I hope). I just need to implement everything right and write whitepaper.
347  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] SpreadCoin on: August 16, 2014, 08:55:45 PM
So, should there be 1440 blocks each day?
Does it mean, during these few days, when block reward is approx. 6.65 SPR, there are minted approx. 9576 new coins a day?
There are 1440 minutes per day, blocks are generated approximately every minute thus there are approximately 1440 blocks per day.

And, if the reward is halving gradually (incidentally, what I appreciate much) each two years, it means right after first year had passed there will be 5 SPR block reward,
so during first year there will be minted 3,066,666 coins?
Am I right?
It is halved every 4 years just like in Bitcoin. After first year (525600 blocks) reward will be 5.79066833 SPR, after two years (1051200 blocks) it will be 4.91466833 SPR. During the first year there will be 3'405'811 SPR.

EDIT: Here is comparison of Bitcoin (blue) and SpreadCoin (brown) rewards per block over time:


When looking at this graph keep in mind that SpreadCoin blocks are 10x faster and reward per block is 10x lower.

Hello Developer,

can you tell us, what level of mining optimization has the wallet?
Are there special piece of code optimized for different CPUs?
Built-in miner is the same as in Darkcoin. There are no CPU-specific optimizations.

It seems to me, that i5 Haswell has significantly higher finding rate than "faster" i7 Ivy Bridge.
How do you measure it? You can find exact hashrate with getmininginfo command (see at hashespersec value).

Should be any difference between HyperThreading on and off on i7?
I think that with HyperThreading hashrate should be higher, that is what HyperThreading for. I didn't check it myself.

EDIT:
can you explain little deeper about threading? Is each thread trying to find a new block, or are all the threads working on the same block?
(The latter seems much more reasonable to me, but I am asking for sure).


Thank you.

Regards,
Andy
Each thread has its own address for generated coins but otherwise blocks in each thread are the same. Well, in fact the same is true for the whole network (additional differences are caused by delays in blocks and transactions transmission).

Seriously? disappeared... and even pulling my last active date? You know... I'm not even upset that I 'lost' this bet, but assuming I disappeared because I wasn't active for a couple of days is silly; if I didn't know any better, I'd think you're trying to piss me off. Surely you took a peek at my post history... I don't post here everyday; I have a life. Actually, I never log out so it should look as if I'm logged in 24/7. The only time I log in is when I have to restart my system or the site goes down. I need to fix that anyways.
I did't mean to offend you, this forum in fact showed that you were offline so it appeared to me that you had logged out shortly after my post. I didn't go futher to explore your post history.

Anyhoo, your choice... you can start a new thread that you won the bet and I owe you (frankly, knowing this tidbit is worth a coin; I've asked several devs for it... most had no clue what the hell I was talking about) or we can use this thread for your payments. Yeah, I'm gonna pay you, but I'll be damned if I'm going to assist with funding your endeavor; I still don't have much confidence in the success of this coin. On the other hand, if you were an established member, they would've been in your wallet shortly after I logged on today.
I don't think there is a need for new thread as there is not much to discuss, you will pay when you can/want. For your peace of mind I can assure you that I would continue to work on my cryptocurrency regardless of this 1 btc, so you won't actually fund my endeavor.

So Darkcoin is also a scam in your opinion: https://github.com/darkcoinproject/darkcoin/blob/master/src/main.cpp#L3591
As well as Bitcoin: https://github.com/bitcoin/bitcoin/blob/master/src/main.cpp#L3214
As you said, these values are used to identify the network. They are the first bytes that each node sends during a connection and they are the first bytes that each node should receive. This way you can easily detect if you have connected to a wrong cryptocurrency network (or even something completely different like a webserver or bittorrent client). Wallet cannot work without these values, they are not specifically for pools. Pools also need to connect to the network so they also need them. For SpreadCoin you can find these values in protocol.cpp: https://github.com/spreadcoin-project/spreadcoin/blob/master/src/protocol.cpp#L23

Note that values that you pointed to in your screenshot are actually for testnet.

My bitcoin address: 1MSL9Ph2RCUnpekpuf6Rofb4kUo1nArsnS

Of course I don't think that either is a scam - but I see the link indicates those values are in their main.cpp file - yours on the other hand is located where people who write guides (and even on the wiki itself) neglected to tell people. Now I'm really wondering. I don't claim to be any kind of techie, but using their instruction, I was able to create the network.py files for the coins who didn't have them listed in the hub. It wasn't until I started to bring nodes online for these fly by nights that I noticed those values weren't in the main.cpp. After asking several devs how I can find them and got nothing but crickets, I came to the conclusion that something must be up with it. Before downloading the files, I always checked the files for the values needed to bring a node online... there was no need to waste my time compiling a wallet for a coin I couldn't set up a pool for. But like I said... this info is instrumental; worth a btc IMO.

And yes, I realize the numbers were for the testnet; the hex value for the real network is located in that file as well.
For DarkCoin these values are in protocol.cpp, for Bitcoin they are in chainparams.cpp.

But all aside - I have no problem paying up; I keep my word. I'm just curious to know why all the instruction provided by members (on this forum, github and others) all point to the main.cpp for the pchmessagestart value. No one has ever hinted that it's listed in a protocol file; this has me wondering whether there's any significance.
Technically it it possible to put them in any file. Maybe for most coins these values are in main.cpp but main.cpp is bloated with many unrelated stuff so devs try to move some code out of it.

Every block I find goes to another spreadcoinaddress?
Yes, this is the same as in Bitcoin. This is purely wallet feature, with some effort you can mine always to the same address.

352  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] SpreadCoin on: August 13, 2014, 11:53:16 AM
I just remembered that before the last wallet update, when i had the old wallet open, i saw a message(in the wallet) about the new wallet and the hardfork at block 2200.

Is this message feature something that only spreadcoin has, or other coins have it as well?


Im sure they can do it with other wallets , but its the only time I have seen it in a wallet!! maybe its a first i dont know but it is handy!!

That's what i was thinking too!

Mr. Spread: can you elaborate a little bit more on this feature please?
This is general feature in many Bitcoin forks. It is used in rare cases when serious vulnerability is found and before a hardfork so you probably won't see it often. Some devs maybe are to lazy to use it.


And I wonder if Dev got his 1BTC from that guy that was saying there was missing bits of the code??
No. My address is still empty - https://blockchain.info/address/1MSL9Ph2RCUnpekpuf6Rofb4kUo1nArsnS

353  Alternate cryptocurrencies / Altcoin Discussion / Re: Suggestions to prevent scammers launch new shitcoins on: August 12, 2014, 01:09:49 PM
We need more miners of this coin. It is a good coin: no premine, fair launch, still solo-minable by wallet.
Would be nice if some pool (or the Dev) would be able to adapt some miner code in order for it to be minable with pools. It is X11 with an adaption in the timestamp code: 64 bit instead of 32 bit. Any poolowner around that has the skills to work on this?

Not possible. The hex values needed to identify the network is missing from the source code: SCAM COIN

^ obvious shit/scam coin called Spreadcoin or something... I couldn't resist, lol. It took me less than 2 minutes to navigate over to github and peek into the code.
My coin is not a scam. This method for detecting scams is flawed:
1. You search for these values in main.cpp. For different cryptocurrencies they may be in different files, for example for SpreadCoin they are in protocol.cpp, for Bitcoin they are in chainparams.cpp.
2. This values are not only for pools, they are necessary for ordinary nodes. If wallet source code is released then they are available to everyone.

For everyone else who is interested there is discussion about this (with me and Lucky Cris) https://bitcointalk.org/index.php?topic=715435.100

Sorry - took me a lil bit to figure out how to upload pics Smiley  but I see you've already left. Does that mean you're going to pay up?


Here's spreadcoin main.cpp with it's missing pchMessageStart hex code:



Here's what's supposed to be in the file:



As you're a dev... you know this is the magic set of numbers that identifies the coin's network. I'll be happy to post proof for you, but you can consult Google.

You must've known that I lost quite a few coins a couple of weeks ago. this really made my day, thank you!

The hex values needed to identify the network is missing from the source code: SCAM COIN
I don't know what hex values are you talking about. Provided source code is enough to build your own wallet and it is the same code that is used to build Win and Mac wallets from OP. Anyone who has necessary skills can make gitian builds and bitwise compare them with provided binaries. So there is nothing missing from source code.

Didn't realize you were the dev...

So nothing missing from the source code, eh? Well then - it's pretty obvious you're not a dev, just a do-boy who handles this thread? You wanna put something done on your claim that nothing's missing from the code? I'm all game buddy - just say the word.
LOL, I'm dev. Unfortunately I don't have much, I can put just 1 btc on my claim.

Hardfork at block 2200.

1. Spacing between blocks changed to 1 minute, this is to make solo-mining easier. In the future I plan to add new features which will give more incentive for solo-mining to make this coin much more decentralized than any other PoW currency.
2. Reward per block is now 10 times smaller so that spreadcoin generation speed and total supply is still the same. Also I fixed stupid mistake in reward computation, now it is correct.

New version: all Darkcoin graphics were replaced + there are small fixes for block explorer.
I set up a DNS seed and a SpreadCoin node on the server (its ip address is built into the wallet), so connectivity should be better now (although it already was quite good).
Also, I built an OS X wallet but I didn't test it, if you will try it please let me know whether it works or not.

We have a new logo (not made by me):

Splash screen is in process.

Next step is to make online block explorer and dns seed for automatic peer discovery, also a website is necessary. Don't expect all of this to happen instantly because I'm the only developer behind this coin and I work in my free time.

When all those infrastructure issues will be solved I will think about implementing some unique features for this coin. I have several sketchy ideas but I don't like to give promises that I wouldn't be able to fulfill, so I will not currently elaborate on them more until developing them in more details.
360  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] SpreadCoin on: July 31, 2014, 10:19:01 AM
I added built-in block explorer, you can download new version. It is available from Tools/Blockchain Explorer.
By default it won't be able to show you full info about transactions which outputs were completely spent, this is beacause wallet only stores database of unspent outputs. Also, showing info about address is unpotimized, currently it works fast simply because number of blocks and transactions is very low.
Nevertheles, it is already usefull. For example, you can see that someone collected almost 3000 coins in one address in block 630 (using several transactions for some reason).
