Proof of Stake Coin List

[cocales]

   GalaxyCoin Scrypt / POS   

[slavo]

EBT is pow/pos, and young, so add it please !

[kokojie]

what's these 30 days min, 90 days max mean?

[slavo]

what's these 30 days min, 90 days max mean?

time to find a pos block

[StakeHunter]

what's these 30 days min, 90 days max mean?

time to find a pos block

Thanks...I've added some description above. And I've shortened the table with:
Stake Age (SA) = min days / max days

Added GLX, EBT

[thundertoe]

Most of the time with these coins the stake mints early during the window. From my past experience, usually the first day eligible. ymmv

these 3 coins are all zero premine zero block halving coins.


CAP 5% every 30 days  daily mintage(pow) 14,400    current minted:  2,800,000     10 per min      

HBN 2% every 10 days  daily mintage(pow) 14,400    current minted:  3,000,000      5 per 30 sec

TEK 40% every 30 days daily mintage(pow)  1,440    current minted:     326,000      1 coin per min


The true power of the stake is in compounding interest.

Here is a calculator to run the math out a few months with.(select compound interest)

+1 to this thundertoe - good statement on compounding interest.
Just a  question on this, I was looking at the code this morning for CAP & HBN - and it looks like they both have the NVC code where they'll start @ 100% and decrease based upon stake diff to a minimum stake. However, CAP and HBN vary because their min stakes are 1% and 100% respectively. Am I reading this correctly? So while they start the same now, as more coins come to market they won't stay the same?

Here's snowcoin's GetProofOfStakeReward() function.   Perhaps y'all can decipher it better than I, for the OP summary.

Thanks for the code - I'll update the list.

Scrypt
Colossuscoin (COL) - 0.5%, 15 days/30 Max Weight (SA 15/30)
100%-PoS 
Thanks for the PoS List

[David Latapie]

Now everyone knows the big names - Peercoin and Novacoin. However, there is a big world of PoS coins out there

These coins are established and have been available for quite some time.  Want to get on the POS train early??

MINTcoin
Hobonickels
GalaxyCoin

I cannot talk for the other too, but Mintcoin is ridiculously undervalued, partly because it is not on coinmarketcap or cryptsy => great opportunity to come in (biggest exchange: http://www.mintpal.com).
This infographic should help you undestand why so much people are jumping in the wagon at the moment!

[Monetizer]

What coin do you guys suggest putting an investment in? I believe habbo nickels will go down in price sooner or later so I would rather not invest in them. (I have a computer runnning 24/7 so staking is no problem)
I am thinking mintcoin, what do you reccon?

Good thread, it's something I've been wondering about myself.

Looks like you might of missed the following:

Emercoin - EMC - Crypto-currency of Emergence - SHA-256 - http://emercoin.com/about/

PoS - 6% per year

Forum topic: https://bitcointalk.org/index.php?topic=362513.0


Gold Pressed Latinum - GPL - Crypto-currency of the Ferengi - Scrypt-Jane - http://scificryptocoin.org/index.php/scifi-crypto-coins/gpl

Stake Stats:
1 year minimum stake
2 years for full stake weight 
5 cent per coin-year consumed (which can be roughly understood as 5% interest annually)

Thx for the list!


Could you add transaction-fees? Imo a very important factor.

btw, is there any coin whose fee adjusts automatically in order to push inflation near zero?

In the best case, fees depend on transaction amount as well, so POS generates the same amount of "free transaction opportunities" for everyone, rich or poor.
