### CoinDayWeight

## What's this?

It's similar to coin-age but age is calculated using 30-day offset and 90-day upper limit.Examples for 1 coin:

Parameter | 0 days | 10 days | 15 days | 30 days | 60 days | 90 days | 120 days | 200 days | ∞ |
---|---|---|---|---|---|---|---|---|---|

CoinAge | 0 | 10 | 15 | 30 | 60 | 90 | 120 | 200 | ∞ |

CoinDayWeight | 0 | 0 | 0 | 0 | 30 | 60 | 90 | 90 | 90 |

## How it's used in the Novacoin?

CoinDayWeight is a parameter of proofhash target in the Proof-of-Stake system.nBlockTarget = CoinDayWeight * nNetworkTargetProof hash must satisfy the nBlockTarget, so greater CoinDayWeight means higher probability for generation of Proof-of-Stake block.
