What is Speedcoin?

Speedcoin [SPD] is a lite version of Bitcoin using scrypt-adaptive-N as a proof-of-work algorithm.

  • 1 minute block targets
  • subsidy halves in 2 million blocks (~4 years)
  • 10,105 million total coins
  • 10,000 million premined coins
  • 105,000,000 coins ready to mine
  • 25 coins per block
  • Every block to retarget difficulty with Kimotos Gravity Well algorithm
  • Scrypt-N algorithm

The main problem with any cryptocurrency is that it does not spread widely amongst Internet users because new crypto coins are mined by not many people (usually a few hundreds only) who well understand computers technology and have special equipment so that ordinary Internet users cannot mine new coins and must to buy it.

The main idea behind Speedcoin is different. It is to evenly distribute pre-mined Speedcoins to millions of Facebook users across the world through an open clear process on our website. Its process distribution is similar to Iceland's Auroracoin but ours is distributed globally.

Any Facebook user simply needs to go to Speedcoin.org and log in to our website and enter Speedcoin address. 1,000 SPD will be sent to him automatically. To ensure the same user does not use multiple Facebook accounts we request that the user have verified Facebook and 10+ people in his Facebook friend list.

To promote the success of Speedcoin worldwide, we use affiliate programme on our website Speedcoin.org and pay 5 Speedcoins as a Reward for each new user. Webmasters can place the Speedcoin affiliate link on their website/s and normal users can sent the affiliate link to their friends or publish it in their blogs. In our opinion, any time you use to spread the news of Speedcoin should be rewarded. That is why we made the affiliate programme.
