1  Alternate cryptocurrencies / Announcements (Altcoins) / [ANN] Tigercoin - TGC | SHA256 with Super Random Blocks | Please Upgrade to V1.1 on: September 06, 2013, 08:17:57 PM

Version 1.1 is released. Please upgrade.


Tigercoin - TGC

TGC is a fork of Bitcoin version 0.8, with addition of super random blocks.

Proof of work with SHA256 is used as in Bitcoin. The following specifications are implemented:
   - Each normal block has 128 coins
   - 45 seconds block time
   - Difficulty retargets every 20 blocks (approximately 15 mins).
   - mining payout will be halved every 3 months (every 172800 blocks)
   - once the payout reaches 1 coin/block, it will stay there to sustain the mining
   - Expected total mined coins will be 47,011,968 coins (not counting the one coin per block inflationary sustaining blocks)
   - 4 confirmations for transaction
   - 50 confirmations for minted blocks
   
   - Random bonus blocks are (on average):
      - 1 superblock of 512 coins every hour (1/80 chance)
      - 1 superblock of 2048 coins every day (1/1920 chance)

   - The default ports are 15660(Connect) and 15661(RPC).

To support early adopters, in the first 3 days - 5760 blocks, all the payouts (including superblocks) will be doubled.

No Premine.

2  Other / Beginners & Help / Is USB Erupter ever profitable? on: September 01, 2013, 06:27:41 AM
The price of USB Erupter going down very quickly, and yet at 0.3-0.4 BTC each, shall we ever get the investment back? At the current diff, each USB Erupter can mine about 2.5X10^-4 BTC per day, which means it can get 0.4 BTC in 160 days (or 5+ months). But with BTC diff rapidly going up, I suspect that the investment can never be recovered. Is my computation correct?
