Tedcoin is a peer-to-peer electronic cash system that is completely decentralized, without the need for a central server or trusted parties. Users hold the crypto keys to their own money and transact directly with each other, with the help of a P2P network to check for double-spending.
Tedcoin is an innovative, secure and energy efficient PoW/PoS coin. It uses a faster PoW distribution mechanism to distribute the initial coins, then after 5 weeks the coin is basically transferred to a pure PoS coin, where the generation of the coin is mainly through the PoS interests.
Tedcoin also adopt a variable PoS rate, which gives the highest payout at 20% the first year, then decrease 5% per year until the 4th year it reaches annual interest rate of 5%, then it will remain at this rate.
Because after 5 weeks it is basically a pure PoS coin, it does not need to be intensively mined, as the PoW payout will remain the minimum. Most coins will be generated through PoS, thus it is a coin that will save a lot of energy compared to other coins.

Extensive testing using network simulation software has shown that 40 seconds is the optimal block time. This allows ample time for blocks to propagate across the entire network. It gives us fast confirmations, while minimizing orphans and forking issues that we saw affect faster coins. Long term, it will also help keep blockchain bloat down. Our testing has shown that a block time lower than 40 second makes a coin unsuitable for long term stability and growth.
Scrypt was chosen as an encryption algorithm. Other candidates were Blue Midnight Wish, SHA3, and Skein. After much analysis we came to the conclusion that such algorithms make for a nice selling point, but fall short of Scrypt in terms of securing a blockchain. Our aim is to create the best coin possible, not lure you in with gimmicks.
We've changed the magic number for Tedcoin. What is the magic number? It's an often overlooked, but very important, variable within the code of bitcoin. This value affects how the entire blockchain is formatted, and is a key factor in determining how peers are matched up over the network. Failure to change this value opens the door to many vectors of attack. Ever load up an coin client and have it start to download the Litecoin blockchain? That is because the developers of that coin neglected to change the magic number to a unique value.
Block reward is 25 coins per block, with a block target time of 40 seconds. Difficulty will be recalculated every 90 blocks, which is much lower than other coin releases. We choose this value for several reasons:
- It allows the network to find it's natural difficulty much faster, ensuring a fair and accurate spread of coins.
- It prevents blockchain stalling from ever happening. No one likes having to issue a hardfork.
We want Tedcoin to be a steadily mined currency, not one that is pumped and dumped. These values will assist us in reaching that goal.
We believe the strongest asset a coin can have is active, talented developers. We will be on the forum daily answering questions and resolving issues, as well as helping to grow Tedcoin by working behind the scenes to develop and deploy services that will ensure success.
You need the Qt4 run-time libraries to run Tedcoin-Qt. On Debian or Ubuntu:
sudo apt-get install libqtgui4
Unpack the files into a directory and run:
- bin/32/tedcoin-qt (GUI, 32-bit)
- bin/32/tedcoind (headless, 32-bit)
- bin/64/tedcoin-qt (GUI, 64-bit)
- bin/64/tedcoind (headless, 64-bit)
See doc/readme-qt.rst for instructions on building Tedcoin-Qt, the intended-for-end-users, nice-graphical-interface, reference implementation of Tedcoin.
See doc/build-*.txt for instructions on building tedcoind, the intended-for-services, no-graphical-interface, reference implementation of Tedcoin.

Tedcoin is released under the terms of the MIT license. See COPYING for more information or see http://opensource.org/licenses/MIT.
Developers work in their own trees, then submit pull requests when they think their feature or bug fix is ready.
If it is a simple/trivial/non-controversial change, then one of the Tedcoin development team members simply pulls it.
If it is a more complicated or potentially controversial change, then the patch submitter will be asked to start a discussion (if they haven't already) on the mailing list.
The patch will be accepted if there is broad consensus that it is a good thing. Developers should expect to rework and resubmit patches if the code doesn't match the project's coding conventions (see doc/coding.txt) or are controversial.
The master branch is regularly built and tested, but is not guaranteed to be completely stable. Tags are created regularly to indicate new official, stable release versions of Tedcoin.
Testing and code review is the bottleneck for development; we get more pull requests than we can review and test. Please be patient and help out, and remember this is a security-critical project where any mistake might cost people lots of money.
Developers are strongly encouraged to write unit tests for new code, and to submit new unit tests for old code.
Unit tests for the core code are in src/test/. To compile and run them:
cd src; make -f makefile.unix test
Unit tests for the GUI code are in src/qt/test/. To compile and run them:
qmake BITCOIN_QT_TEST=1 -o Makefile.test bitcoin-qt.pro
make -f Makefile.test
./tedcoin-qt_test
