It will be released at a later date, no later than 25th January 2018.


Newer features will be implemented.


We're in no way related to the original SpreadCoin developers. Just continuing where they've left off since 2016.

That'll be great! We're working on the fork right now, I will update this thread as soon as we're done.

We are officially forking off SpreadCoin on 31 January 2018, 00:00 UTC
Exact block number to be confirmed at a later date!

All existing SpreadCoin (SPR) holders will get 1:1 fork of the coin on the new chain.

The development of SpreadCoin is dead, this fork aims to revive it.



BitcoinSpread 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:
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:
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.

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
