**Please vote for us on MintPal!****[ANN] [FRAC] Fractalcoin****Introduction**Fractal Coin is a revolutionary X11 PoW coin featuring a new difficulty adjustment algorithm (Slingshield) and a unique two phase distribution plan which ensures that the coin remains sustainable and economically viable indefinitely. During the first 28 days 90% of all coins will be distributed before the coin then transitions to Slingshield and percentage based fees which will begin to form the backbone of the block rewards. Eventually the block rewards will be completely provided by percentage based fees beyond the initial distribution period.

**Specification**- X11 Proof of work.
- 1 Million coins total.
- 60 Second block time.
- Slingshield providing advanced 51% protection by increasing hashrate required for attack to 71%.
- 90% of coins mined in the first 28 days of mining to combat inflation and price instability.
- Digishield transitioning to Slingshield to provide sustainable difficulty adjustment tailored to the coins timeline.
- 0.5% transaction fees after 28 days, ensuring that mining remains profitable without hyperinflation.
- 0.5% premine to aid development.

**Features****Percentage fees**Once activated and the block rewards lowered, the contribution of fees to the block reward will increase significantly. As such by the end of the block schedule the coin will be able to totally sustain itself with a high block reward solely comprised of coins from percentage fees. This ultimately ensures that the Fractalcoin network will remain secure for the significant future and that it'll also be economically viable.

**Slingshield**Once activated Slingshield adjusts difficulty dynamically as transactions are added to a block. This significantly decreases the risk of attacks such as conducting a double spend as with Slingshield the attacker would now require 71% of network hashrate as opposed to 51%. This in turn ensures increased network security and a fair balance between both loyal miners and multipools that only mine blocks with high transaction fees.

Full details about the Slingshield difficulty adjustment algorithm are available in the white paper

here.

**Fair and stable launch**Initially the block rewards for the first 30 blocks contain no coins, this is to ensure that the launch is as fair as possible. This means that pools have time to confirm that their systems are working as expected and that everyone has a fair chance to unlock their wallets and set up solo mining if they wish.

**Transparent premine distribution**There will be a 0.5% or 5000 FRAC premine that will be used to fund further development of the coin and reward the founders and developers working hard to make this coin a reality, it will be distributed as follows:

- 0.1% to each of the 3 founders at Cryptolabs Technologies, creator of Fractalcoin.
- 0.2% for bounties and development of the coin.

**Pools****Exchanges****Reward Schedule**After the initial 30 blocks the reward schedule for this coin features a rapid distribution of coins for the first 28 days. Large rewards are available for those mining on the first and last day of the initial phase to both reward early adopters and also to entice those who may have missed out originally at release.

**Initial Fractal Phase: Digishield**- 1: 5000 FRAC Premine
- 2 - 31 : 0 FRAC (to ensure that launch is fair and everyone including pools are ready for launch)
- 32 -1471: 40 FRAC (1 day)
- 1472-20191: 20 FRAC (13 days)
- 20192-38912: 10 FRAC (13 days)
- 38913-40352: 40 FRAC (1 day)

**Final Fractal Phase: Slingshield and 0.5% fees activated**- 40353-318230: 1 FRAC (approximately 221 days)
- 318231 and onward: 0 FRAC

From block 318231 onwards the block reward will be fully sustained by means of percentage fees.
