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

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 TransactionsSpreadCoin 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.

https://bitcointalk.org/index.php?topic=869289Also 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:
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:
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 GuideWindows:

rpcthreads to value greater than 4 in spreadcoin.conf.
