Talkcoin (TAC) is a new digital currency that lets users chat in decentralized public / private chat rooms securely and anonymously.
Talkcoin delivers next-gen privacy, security and anonymity, built on Bitcoin's decentralized blockchain and encryption technology to make sure no one can spoof, block, delete, modify or snoop on your private communications and so you can access them any time from anywhere.
Other chat systems require servers or a direct connection to the users you want to chat with, Talkcoin is the first totally decentralized communication system.
For more background information on Talkcoin, visit the original Dev's
thread.
Currency InformationTalkcoin is a currency for storing value, exchange and secure communications.
Each chat message has a small TAC fee, all fees are paid back into the TAC economy by being destroyed in the genesis block.
This reduces TAC supply and increases velocity, which creates demand and delivers value to investors.
To avoid problems from block halving making mining unprofitable and ensure enough TAC are available for messaging, Talkcoin has a decentralized vote feature so twice per week users can vote to adjust block reward up or down by 10%.
Talkcoin was released on 4th May 2014 and (as of 4th August) total supply is ~7 million TAC, and block reward has been reduced from 25 TAC per block to ~15 TAC.

NIST5Talkcoin designed the NIST5 hashing algorithm to provide a better combination of power efficiency and security than existing algorithms. NIST5 chains the 5 final round candidates for the National Institute of Science and Technology's SHA-3 hash competition, which were all selected for their performance & security (BLAKE - Grøstl - JH - Keccak - Skein). NIST5 excludes algorithms eliminated from the final round for security and performance concerns such as CubeHash, Luffa, simd, Shavite-3, ECHO as found in X11 and Hamsi and Fugue added in X13.

RoadmapThe first main core feature, private chat rooms, was released successfully and work is now focused on improving the core functions, user experience, developing our website and increasing awareness in the market. Future features are focused at increasing users privacy, anonymity, and improved communications features across different devices.

Talkcoin uses NIST5 so miners need:
- Talkcoin's NIST5 port of SGMiner: http://talkcoin.org/talkcoin-miner.zip
- Set your kernel -k to 'talkcoin'
- Intensity can be set higher than other algorithms
- Thread concurrency, shaders, gpu threads should be set as normal
Example ConfigTalkcoin SGMiner command line example:
sgminer.exe -k talkcoin -o http://127.0.0.1:8000 -u user -p x
