      "title": "FirstCoin: A Ponzi scheme cryptocurrency from a technical point of view",
      "body": "What is Firstcoin?\n==================\n\nThere are no technical white papers explaining the technical decisions\nnor any form of [community developing this cryptocurrency](https://github.com/firstcoinofficial/firstcoin) except:\n\n-   1 minute block targets\n-   subsidy halves in 2.5M blocks (\\~5 years)\n-   110 million total coins\n-   6 confirmations\n-   1 Satoshi per block\n\nMost important (and missing in this description): 109,999,999  coins are already mined.\n\nBad design or Fraud by design?\n==============================\n\n[FirstCoin](http://firstcoinproject.com/) has a supply of 110,000,000 coins. I suspected the mining algorithm is similar to Bitcoin, where the number of coins generated per block is set to decrease with a [50% reduction every 210,000 blocks](https://en.bitcoin.it/wiki/Controlled_supply) (Starting with 50 Bitcoin for the Genesis block). \nBitcoin has chosen this decreasing-supply algorithm because it approximates the rate at which commodities like gold are mined.\n\nBut things are different in the world of Firstcoin: The reward is **fixed** to 1 Satoshi (0.00000001 [FirstCoin](http://firstcoinproject.com/)) for every single block to be mined!\n\nIf you wonder how the supply of 110M coins can be reached: There is a special case for block 2 coded in the [GetBlockValue](https://github.com/firstconn/firstcoin/blob/9d5f136ccf7e4f7a4c4d62f7af6873d067bd4e88/src/main.cpp#L1092) function:\n\n``` {.c}\nint64 static GetBlockValue(int nHeight, int64 nFees)\n{\n    int64 nSubsidy = 1;\n\n    if(nHeight == 2)\n    {\n        nSubsidy = 109999999 * COIN;\n    }\n\n    if (nHeight > COIN + 1)\n    {\n        nSubsidy = 0;\n    }\n\n    return nSubsidy + nFees;\n}\n```\n\nSo there is only **1** Coin left to mine and the inventor of Firstcoin [sent the 109,999,999 to\nhimself.](http://explorer.firstcoinproject.com/block/34853dd4108804f3df772ce24fd99ea974af09847708384adfbcbe30e56728c4)\n\nThis is obviously not the way a healthy cryptocurrency should be designed. There is no incentive to mine because there is actually **no reward**. This is also reflected in the current mining difficulty: [0.0042](http://explorer.firstcoinproject.com/).\n\nThere is no mining software available for download (nobody would use it anyway) and I suspect only the inventor keeps mining blocks to keep the network alive.\n\nSo taking over the mining (to prevent transactions to happen or reverting history) should be easy.\n\nFirstCoin.Club: Ponzi at work\n=============================\n\nFunnily you can invest in Cloud-Mining and other fake packages to get monthly rewards (between 3% and 7.5% of the invested coins) in the so-called [FirstCoin.Club](https://firstcoin.club/).\n\nThe reason Firstcoin increases in value is the fact, that still people get fooled by the Firstcoin marketing to buy Firstcoins at the [LiveCoin exchange](https://www.livecoin.net/) to \"invest\" in [FirstCoin.Club](https://firstcoin.club/).\n\nMost likely the promoter/inventor of Firstcoin will vanish once investment slows down and the scheme collapses. He will have made enough profits selling some of his remaining 109,900,000 Firstcoins!",
