[ANN] SpreadCoin | True Decentralization (No Pools) | Testing New Masternodes

SpreadCoin 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 with no premine.

Pool Prevention
To prevent pools each block must be signed with the private key which correspondents to the coinbase transaction. See whitepaper for more details.

Parameters

Algorithm: SpreadX11
Block generation: 1 minute
Difficulty retargets: every block based on last 360 blocks
Reward starts at approx. 6.66 coins per block
Block reward is smoothly halved every 4 years
Total supply: 20 mln coins
No year 2106 problem

Initial reward was 66.66 coins per block and spacing between blocks was 10 minutes, this was changed after hardfork at block 2200.

Truly Decentralized
In Bitcoin mining power is concentrated in large pools. This puts the whole network at risk in case these pools will become malicious or if their security will be compromised. In SpreadCoin there are no pools, mining power is spread around many solo miners.

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

Smooth Reward Decrease
Unlike Bitcoin, there are no abrupt reward halvings in SpreadCoin. Block reward is smoothly decreasing over time.

Mining
You can mine directly from the wallet, just go to the mining tab and press 'Start mining', you will start mine to your wallet. Thread about mining SpreadCoin: https://bitcointalk.org/index.php?topic=869289

Also you can mine to a specific address (this is useful if you are mining on several computers). To do so:
1. Use existing or better generate a new address.
2. Open debug console (Tools -> Debug Console) and enter:

Quote

dumpprivkey SYourSpreadCoinAddress

3. You will get your private key. Then open spreadcoin.conf or create it if it doesn't exist (D:\Users\<username>\AppData\Roaming\SpreadCoin\spreadcoin.conf on Windows) and add the following line:

Quote

miningprivkey=YourPrivateKey

4. Restart your wallet if it was running.
In the Mining tab you will now see notification that all mined coins will go to this address.

Mining Guide
Windows: https://github.com/spreadcoin-project/SpreadCoin-Wiki/wiki/Mining-Guide
By default you can mine only from 4 machines to the same wallet, to increase this limit set rpcthreads to value greater than 4 in spreadcoin.conf.

AMD GPU Miner
Windows binary: http://spreadcoin.net/files/Spread-GPU-miner.7z
Source code: https://github.com/spreadcoin-project/spreadcoinx11-sgminer

Don't forget to read included readme, it describes how to launch it. Even if you did solo-mining before it is still worth reading.

You need latest drivers to use this miner. Known to work on 14.9 installed from file named amd-catalyst-14-9-win7-win8.1-64bit-dd-ccc-whql.exe from http://support.amd.com/en-us/download/desktop?os=Windows%207%20-%2064

And here's a GPU miner for the NVIDIA crew. Compute 3.0 support should be easy enough, but for now it's 3.5/5.0/5.2 only.

I have plans to improve it in the future but nothing particular is yet implemented. Currently there are just some small improvements like fixed year 2106 problem.

You still can't connect to the network? I have 23 connections, I don't know why it doesn't work for you. How do you add nodes? You can use for example "addnode 61.251.187.134:41678 add" in console.

Hi all!

I'm pretty new to this world of cryptocurrencies and I want to launch my own coin.

Here are its parameters:
Algorithm: X11
Block generation: 10 minutes
Difficulty retargets: every block
Initial reward: 66.66666666 coins per block
Block reward is smoothly halved every 4 years
Total supply: 20 mln coins

I may change these parameters in the future. In particular, I want to implement my own mining algorithm which I think will be great but I'm not yet sure if it is possible to do what I want.

Launch time: in one hour (9:00 UTC).

This should be fun... block reward 66.66666666? Maybe you should have just went with 666. No plan, just do a coin for fun called "SpreadCoin".. As in bend over, spread wide and take it deep? lol
