What is Mediterraneancoin?

Mediterraneancoin is a lite version of Bitcoin using an experimental new proof-of-work algorithm.

The new PoW algorithm is called "HybridScryptHash256".

It is described in detail here: https://github.com/mrtexaznl/mediterraneancoin/releases/download/v0.8.5.2/hybridscrypthash256.pdf

The idea is to allow all the users of erupters and similar small devices to mine an altcoin without having "whales" coming and disrupt mining. With HybridScryptHash256, each HASH256 mining iteration with an erupter is encapsulated between two scrypt stages (whose parameters depend on the current difficulty). In this way, a good amount of CPU power (or maybe even GPU power) is necessary for each HASH256 dedicated hardware. If a miner owns a lot of HASH256 computing power, in order to mine Mediterraneancoins, he will need also a corresponding CPU power. If the correspondent CPU power is not available, then the HASH256 compunting power is automatically limited.

  • 1 minute block targets
  • about 6 hour to retarget difficulty

Special reward system: random block rewards

1-100k : random 1-100 MediterraneanCoins reward
100k—200k: 1-200 MediterraneanCoins reward
200k—300k: 1-150 MediterraneanCoins reward
300k—400k: 1-100 MediterraneanCoins reward
400k—500k: 1-70 MediterraneanCoins reward
500k-600k: 1-40 MediterraneanCoins reward
> 600k : 20 MediterraneanCoins reward (flat)

after that, subsidy halves in 1036k blocks (~1 year)

  • 200 million total coins
