 This is the new official thread of spreadcoin. For the old thread go here Website | Forum | IRC | TwitterCompletely Decentralized Digital Currency without PoolsSpreadCoin is a new cryptocurrency which is more decentralized than Bitcoin.
It prevents centralization of hashing power in pools, which is one of the main concerns of Bitcoin security.
SpreadCoin was fairly launched on 29 July 2014, 9:00 UTC with no premine. | Hash algorithm: | SpreadX11 | | | Total supply: | 20 million | | | Block time: | 1 minute | | | Block halving: | smoothly halved every 4 years | | | Initial block reward: | 6.66 SPR | | | Port: | 41678 | | | RPC-Port: | 41677 | |
 One of the first apps to be built into the wallet is the vanity generator (or vanity gen) which allows anyone to create personalised payment addresses.
The easy to use wallet lets you search through trillions of payment addresses allowing you to find one or multiple vanity addresses,
which are then stored safely along with the private keys on your own computer - and nowhere else.
Searching using the vanity gen is probabilistic, so the amount of time required to find your chosen address patterns depends on how complex the pattern is,
the speed of your computer, and a little bit of luck.
You can use the vanity gen for a bit of fun, to make your address standout from the crowd or to create a link to a brand, business or other organisation.
You can even search for addresses that others might be willing to buy from you.
  Watch the VanityGen tutorial: (created by e1ghtSpace) Additional advanced features (see whitepaper) that are unique to spreadcoin:  SpreadX11 is different from plain X11 by introducing a sophisticated pool prevention mechanism.
With SpreadX11 every block header contains additional information (MinerSignature and hashWholeBlock).
With the help of this information the protocol ensures that the miner of a new block is always also the first one to know the content of the whole block
and the private key to spend the coinbase transaction. (contrary to pool mining where the pool operator is the first one to know those things)
So when a miner finds a block, he must himself sign and transmit the block to the network (like solo mining), instead of having a pool handle this for him.
This effectively prevents pools by making their rules non-enforceable,
since any miner in any assumed pool can always just steal the block reward
instead of following the rules set up by the pool. SpreadCoin uses a more compact representation for signatures in transactions.
SpreadCoin as well as Bitcoin uses ECDSA signatures. While bitcoin keeps a copy of the public key of the corresponding signature around,
SpreadCoin ommits this by recovering the public key on the fly directly from the signature.
This way it is not necessary to keep the public key of every ECDSA signature in the blockchain,
so this leads to *smaller transactions and hence a smaller blockchain (at the cost of a few CPU cycles more).
(*reduction in size of transaction from 139 or 107 bytes in Bitcoin to 67 bytes in SpreadCoin.) Unlike Bitcoin, there are no abrupt reward halvings in SpreadCoin. Block reward is smoothly decreasing over time.   The time stamp field in the block header is now 64 bit instead of 32 bit (Bitcoin) so that much farther date times are possible (>Year 2106) | | | | | | | | | | | | | (spreadcoin-linux64.zip) | (spreadcoin-win32.zip) | (SpreadCoin-Qt.dmg) | (Source Code) | |

Bootstrap Files:
http://www.spreadcoin.info/bootstrap_files.zip
(how to apply bootstrap files: shut down your wallet, go to SPR blockchain folder, delete all folders (blocks, chainstate), paste the zip content so that the folders get replaced. Done)
If you have problems connecting,
use these Seednodes:
addnode=5.35.253.206
addnode=94.23.23.194
addnode=52.17.253.8
addnode=37.59.18.108
Be careful when creating paper wallets or addresses with third party sites, like walletgenerator.net or universalwalletgenerator.net.
There have been cases where people sent SPR to the non-compressed public address.
This has fatal consequences since SPR uses compressed public addresses ONLY.
Always send SPR to the compressed public address, or else your SPR are lost forever.

Ok, just 25 more minutes to release everything else.
You were 1 second off! Try to make it exactly to the minute second on the new thread. That'll be cool. Yes, I will release both ANN and website exactly at 15.00 CEST, which is in 4 minutes and 42 seconds ...  |
|

everything is ready, but the roadmap will need a little longer, so don't be surprised to see a "coming soon" there.
(I will release it later today... it just needs a little bit more thought)

everybody here? good, just a little more than an hour to go... |

Not bad... it looks like you carved it out of 3D wood...  |

FYI,
I own
spreadcoin.info
spreadcointalk.org
spreadcointalk.com
spreadcointalk.net
servicenode.org
servicenodes.org
I hold these domains in the name of the community, I will never sell them or lose them.

 Wonder who owns that? (not me) Yep, that's what squatters do, we shouldn't be surprised that a shark has sharp teeth... I'm sorry to say, but I blame Mr.Spread... He showed his carelessness on many occassions. (losing his wallet, getting banned for 2 weeks, finally disappearing completely, etc...) If you read the first maybe 30 pages of this thread you will see that he already shared his groundbreaking ideas while still uploading the wallets to dropbox or mega...  He could have so easily registered spreadcoin.com (or better yet .org) during those first weeks, for what... 10$ a year? You can easily register domains by paying with bitcoin. In hindsight it looks like Mr.Spread was very surprised (maybe even overwhelmed) that spreadcoin caught so many people's attention... and yes, also the attention of these domain squatters. Anyway... I'll gladly continue the work of this genius, but with a little bit more integrity and reliability.  |

22 hours and 45 minutes to go...  My inbox pings, its Goergem (so it must be important) and.......... I hear you mention those names ... Goergem, Gerogem... who are those people? |

George, thank you for everything. I'm well aware you've had to work your arse off on this.
I haven't even started yet, just wanted to show the community that I really mean it. And I also do all that for myself: spreadcoin is the best opportunity for me to start a crypto related career. (I am a selfemployed programmer since more than 10 years now, and I guess it's about time to start a serious secondary business. Being my own boss gives me the necessary flexibility. ) EDIT: looks like we are going to do the update in 24 hours, but everybody keep PM me about your preferences (24 or 36 hours)! |

Linux binaries are finally here:
Nice work. Can someone test this please? (both daemon and qt please)
Just to go in the opposite direction - I tested ’em on an existing ubuntu 14 installation that has basically everything installed and both worked. Cheers Graham Thank you for your feedback. |

Either will be good for me although I'll likely be extremely drunk in 36 hours...will be watching the boxing.
That's exactly the best mind state to be in... Just give me your vote, 24 hours or 36 hours... best thing is to PM me directly, and I will communicate if it's 24 or 36 later today... |

Yes, we need 24 hours for the DNS records to be updated worldwide. So in 24 hours will be the earliest possible moment. If there are more people active in 12 (or 36 hours) we can also do the ANN in 36 hours? So please everybody tell me when you are best available, in 24 or 36 hours? Both times are fine with me. I want to have as many people as possible around when the ANN goes live. BTW: This is now an official deadline, no more delays I can think of, we have gone thru everything. (and good thing is I have 24 hours more to polish everything... ) |

im in adelaide time 0930 gmt ( i think ) ... i can also pretend to troll too ... but im not so good at it  ... #crysx Whew! We are on opposite sides of the earth... |

I am now slowly switching DNS servers to point to my new server for
spreadcoin.info
and
spreadcointalk.org/net/com
so over the next say 24 hours you might have problems accessing these pages...
until the DNS caches worldwide are updated...
Best don't access these pages at all for the next 24 hours....
stay tuned.
Ah cool, and how soon can we expect the new ann? Can you PM me before you post it? I want to be on the first page. Good point, let's coordinate this a little better... For me it's now about 14:43 in the afternoon. See here to get my time: http://www.timeanddate.com/time/zones/cestSo when is the best time for you guys? When are you most active? Let's arrange an appointment for an exact time I will go online with everything, say tomorrow 15.00 CEST? Just visit this website: http://www.timeanddate.com/time/zones/cest to know when exactly it will be 15.00 CEST.. This would mean in nearly exactly 24 hours from now. So what timezones are you in? BTW trolls are invited too.... Every good respectable ANN thread needs one troll in the first page... so we'll see... |

Just to go in the opposite direction - I tested ’em on an existing ubuntu 14 installation that has basically everything installed and both worked. Cheers Graham damn ... missed so much ... ill test the spreadminer on one of the fedora linux install tomorrow ( ubuntu is debian based ( .deb ) and fedora is redhat based ( .rpm ) ) ... i was swamped today ... let you guys know how it goes ... im guessing it is not the optimized miner ... edit - DUH! of course it isnt the optimized miner - gerogem already said it was the base source code one ... i really need sleep ... #crysx Oh, you mean the cpu-miner branch? https://github.com/spreadcoin/spreadcoin/tree/cpuminer1.2I can try and built that later next week. |

I only mentioned it if you want to join to ask him about how litecointalk deal with spam bots. lol
Now that I can concentrate on finding a solution it's just a matter of time... |
