Tigercoin - TGC, is a fork of Bitcoin version 0.8.99, 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) - Expected total mined coins will be 47,011,968 coins - 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 encourage early adopters, in the first 3 days (1st 5760 blocks) all the payouts (including superblocks) will be doubled.

tigercoin's Issues

Valid blocks rejected when parent has been marked as orphaned

When a valid block is received that has a parent marked as orphaned in the database, the client rejects the valid block stating íncorrect proof of work'.

Reason is the client detects it has the parent block of the received block in the database, so it continues with the process of accepting the block. However, later in the process, when checking the previous block. Not using the orphaned block, but the height-n block marked as being the actual valid chain.

The result is a client rejecting the same valid block from different peers, disconnecting and banning those peers in the process because they are 'misbehaving'.
