This is the new official thread of spreadcoin. For the old thread go here





Website | Forum | IRC | Twitter


Completely Decentralized Digital Currency without Pools

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 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:

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)

If you have problems connecting,
use these Seednodes:

Code:
addnode=5.35.253.206
addnode=94.23.23.194
addnode=52.17.253.8
addnode=37.59.18.108



WARNING! SPREADCOIN USES COMPRESSED PUBLIC ADDRESSES


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.

Roadmap:


   
   
UBA stands for Universal Blockchain Analyzer.

It's a built-in module that specializes in reading other coins blockchain data.
It creates indexed and secured datastructures that are optimized for their distribution
over the servicenodes network to be used for the decentralized blockexplorer
UNA stands for Universal Network Analyzer.

Once we have agreed on a methodoly for anonymous and decentralized big data,
we will start development of another built-in module that scans network traffic caused by the hosted daemons.
We will leave the daemons alone and not use their RPC services to ask them for info,
we will rather deduce any info from the network streams themselves.





Decentralized Blockexplorer

Competitive collateral servicenodes each running a UBA module will enable spreadcoin's first decentralized service:
A decentralized blockexplorer operating from within the spreadcoin wallet, allowing servicenodes to host any coin they like.
The ongoing "Altcoin Taxonomy Project" and its implementation of coinURIs will create the largest best reviewed database of altcoins,
encouraging a more informed decision-making among both users and servicenode operators.
Anonymous & Decentralized Big Data Methodology

Big Data done the wrong way can pose a great danger to both privacy and decentralization.
Therefor preliminary research is currently done to explore privacy, security and validity issues.
Note that the potential monetization and profitability of Big Data is completely irrelevant at this stage.
It is entirely possible that Big Data will turn out to be incompatible with true decentralization principles,
in which case we will limit the use of all analyzed network data to merely improve the operation of servicenodes.
Proof Of Bitcoin Node / Proof Of Any Node

Proving that a full bitcoin node is exclusively installed and used by a single servicenode requires a
solution similar in complexity and about as groundbreaking as solving the double-spend problem in bitcoin.
Solving PoBN will likely allow the creation of a decentralized exchange and (should a valid big data methodology be found) a big data market.

Thanks everybody.

Expect a roadmap later this day. I need a little bit more time to plan everything.

Meanwhile please test the new website, the wallets, etc...

I plan on having my own implementation of a service node ready for testnet by end of this month.

Stay tuned.

"Eventually, most nodes may be run by specialists."
Satoshi, April 2009


A quick sneak peak of how the new website & Ann thread will look like, and what kind of design elements they will include:



I will use a lot of such animations to visualize every aspect of spreadcoin and its servicenodes.
(they won't be GIFs when finalized but javascript driven realtime animations, but I will have to use GIFs for the ann thread here.)

PS: those simulations are not very accurate and are only here for visualisation purposes.

Awesome, looking forward to it!
The website tooks great btw, the only thing I would change is the "fork me in github" banner. I would move it out of the way of the links on the left.
I don't know if this happens on PC, but on my iPad the banner overlaps the website links.

Not much content yet I admit, but atleast it's a clean start.

Yes I am aware of that.

I will make it so that it disappears when it starts bleeding into the links section.
