Example of Geometric Decay Minting Model:


Arithmetic is just a line.

Solidcoin 2.0 Coins/Block Code:

Code:

BaseValue = 32;
BaseValue -= (blocknum/1000000);
if(BaseValue<4) BaseValue=4;
CoinInflationModifier = (Difficulty/50000.0);
BaseValue += CoinInflationModifier*BaseValue;

I think IX coin is the one with 580k premined, not bitcoin.

Thank you.

I read

Nasakioto premined 580k coins

as

Nakamoto premined 580k coins

Does Minting Model = Logarithmic mean there is a fixed maximum number of coins. But these are mined using logarithmically diminishing rates? (I'm not an expert at all the alt-chains).

If so, you might want to include the maximum number of coins those Logarithmic systems will approach.
i.e. 21,000,000 for bitcoin.

Also perhaps how far down the curve each Logarithmic system is. Gives a feel for early adopter status.
i.e. bitcoin is projected to reach 50% distributed on (X date).

That is correct, good suggestion.

More criteria

Notice period : how long ahead of the go-live the coin has been advertised.
Tax : is there a tax like in SolidCoin.
Relaunches : how many times has the coin been relaunched
Topology : centralized (SolidCoin2) / distributed (others)

Do you have somewhere I could find relaunch info?

How is the SC 2.0 premine "disputed".  The owner/king admits 13 million coins were premined.

[Lolcust]

Please add "unknown amount h4x-min3d during first day" in SC2

They aren't useable and new information should appear as the source becomes open (if it does)

[t3a]

If by premined you mean the number of coins that were generated in the genesis block then the premined amount for both Bitcoin and Namecoin is 50.

GeistGeld's minting model was linear and Solidcoin 1.0 was logarithmic I believe.

"Logarithmic" and "Linear" are a bit ambiguous I think. I would change them for "geometric series" and "arithmetic series" respectively.

Yes, logarithmic isn't even the right word, it just looked logarithmic to me when I saw the graph, but upon further investigation it is indeed geometric.

Hey lulz, could you please fill me in on how many coins there are per block?
