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 * nNetworkTarget

Proof hash must satisfy the nBlockTarget, so greater CoinDayWeight means higher probability for generation of Proof-of-Stake block.
