GrowthCoin (GRW) Crypto Currency

GrowthCoin (GRW) – a fork of Diamond, with several algorithms fixed and improved. It is decendent of Novacoin/PPCoin with Pow/PoS. It combines the great features from Luckycoin (random blocks) and Florincoin (transaction message).

Proof of stake coin is more resilient to 51% attack. Since 51% hashpower is not enough to execute a 51% attack. The attackers must also have at least 51% stake.

GrowthCoin provides monthly interest rate of 5.95%, for stakes that are held during that period of time. This equivalent to an annual interest of 100%. PoS blocks will be generated if the stake are held for more than 5 days. There is a hard limit of 2 billion coins.

PPCoin (Peer Coin) - Crypto Currency

PPC Specifications:

• Blocks every 10 min
• Coin supply* non-deterministic coins will be available
• Difficulty adjustment each block
• Hashing algorithm SHA-256
• Reward varies on difficulty coins per block

Peer Coin, abbreviated PPC is a cryptocurrency which is forked from bitcoin. PPCoin aims to achieve high energy-efficiency while keeping as much as the official Bitcoin properties as possible.

PPCoin works with Stake/Proof-of-Stake, this is a term referring to the use of the currency itself to achieve certain goals.

PPCoin uses proof-of-stake to provide minting and transaction processing of place of proof-of-work. Unlike Bitcoin ppcoin does not require the use of energy to sustain the network. Proof-of-work currently remains the most practical way of providing initial minting of a cryptocurrency so it was decided to keep it as part of the hybrid design.

Untill v0.2, central checkpointing was a critical part of the protocol. The main purpose of this is to defend the network during the growth period and to ensure a smooth upgrade path if any critical vulnerabilities are found. Central checkpointing will slowly be weakened and should eventually removed from the coin.

Unlike Bitcoin there is no hard cap on the amount of coins that will be created. Bitcoin is limited to 21 million coins where PPCoin only has a hard cap of 2 billion coin in the code. There is no intention to limit the amount of coins that can be generated.

“There is a 2-billion coin max value in the source code, however that is only used for consistency checking and is not meant to be part of the minting design.”

Pennies (CENT) Coin - Crypto Currency

Introducing indivisible cryptocurrency- Pennies (CENT) Coin

Pennies [CENT] are a unique new cryptographic coin without decimal places. Every easy to mint coin is a single unit and is designed with Proof of Stake savings in mind. Pennies are based on scrypt-jane and set to retarget at long intervals to allow for easy CPU-based mining.

Specifications:

No decimals, no micro units, each penny is 1 coin.
1 CENT per block, 1,000,000,000 (this is 1billion, not 1 trillion) total cents via PoW.
Scrypt Jane (YAC) based, so mine via "Command Line Banking" and "setgenerate = true"
Progressive diff adjusment, targeted N factor retargeting at 1 week.

Quark (QRK) - Crypto Currency

Quark is a crypto-currency that allows online coin transactions. Quark uses nine rounds of secure hashing from six different algorithms to encode Quark transactions securely.

Specifications:

Super secure hashing: 9 rounds of hashing from 6 hashing functions (blake, bmw, groestl, jh, keccak, skein). 3 rounds apply a random hashing function.
* CPU mining
* Quick block generation: 30 seconds
* 2048 QRK per block (halving every 60480 blocks ~ 3 weeks)
* Block reward will never drop below 1 QRK
* Total of 247 million QRK will be mined in ~ 6 months, after that ~ 1 million QRK p.a. (~ 0.5% p.a inflation)
* Difficulty retargets every 20 blocks (maximum 10% up or 50% down)
