By using scrypt as their hasing algorithm, albeit choosing odd parameters for it, LTC really did some innovation there.

Personally, i'd like to see a cryptocurrency introducing a "tax" on coin hoarding, to keep the money flowing thus driving the economy

Proof of stake requires centralization, which is against bitcoins design philosophy.

Should I send you a pull request with my ppcoind side changes, or are you planning on redoing it yourself?

The ppcoind-side changes are basically a straightforward port of the GBT patches for bitcoind. The only thing that I needed to change in those is adding a call to the block signing function in submitblock.
Sunny, could you comment on how you're planning to handle block signing in the official GBT support update? In my implementation the GBT client just sends a zero-byte signature, and ppcoind then calculates the real one. Letting the GBT client sign it seems like a lot of unnecessary complication on that side. But another option would be to not send the varstr at all. I send it as a zero length varstr, as it seemed easiest, will the official one be compatible with that?

The Stratum server also needs some changes because ppcoin has a slightly different block and transaction format (adding a couple of fields), and only accepts compressed pubkeys in the coinbase txn, not pay to address. My changes basically boil down to those two things, they're the bare minimum required.

Go the satoshi-quo -- I am not displeased -- you're using my mining function (with pretty much no wikipedia attribution anywhere btw other than Satoshi's paper *), and I am also attached to it, and frankly I did guess that would be the likely, and with some justification, community response.  And indeed as I said in another post I appreciate the Satoshi-quo quite strongly for concept stability that may affect investors confidence.  And I'm game to see how that turns out.  It'll be an interesting ride.

(Here's a ppcoin like idea I wrote before reading about ppcoin.  I havent quite managed to decipher the ppcoin wiki page finding it hard to find isolate a concise definition of its mechanism and intended low level effects.  Maybe someone who has internalized ppcoin could skim this idea below and tell me if is the same as ppcoin (but simpler?) or not.)

There might be other ways to tilt the field towards p2p control also without changing the mining function.

One could give coins accompanied by first 4 year (50 coin block private keys) from the block chain some definitional hashcash mining boost.  This boost only has value for protocol voting, but NOT coin reward and could be an interesting drag on corporate control.  Would give Satoshi some anonymous power if he is still around and mining.  There'd have to be some coin reward to encourage the GPU miners with old private keys to play and keep the p2p aspect going, other than altruism, but it could be a different payout.  The generation 1 private keys boost level would frustrate subsequent control centraliztion.  Also the boost private keys are the first miner original keys only, the boost cant be transferred bitcoin purchase to the new address private key.

PPC rocks
 Don't change the name. I think you all who want to change the name are thinking of peepee coin when you should be thinking of peer2peer coin.

POS love it.
 In my humble opinion the problem the general public has with bitcoin is that "These miners" are just creating the currency out of thin air and that they are profiting from nothing. With proof of stake it gives the average person who wants to buy in a way of generating income without running massive computers.

And a question:

So in POS (sorry I didn't read through all pages and this probably has been addressed) are first coins seen first coins spent?

So I receive 50 coins on 1/1/xx, receive 5000 coins on 1/10/xx, spend 50 on 1/15/xx.

Are my first POS eligible coins on 2/1/xx or on 2/10/xx?

edit*(Corrected the date above to 2/x and to say assuming 1/1 to 2/1 = 30 days)

Thanks.
