Plans for development are as conservative and/or radical as the changes that anyone feels free to submit Wink

The "1st draft" version that I released contains some significant changes, mostly from the latest versions of Novacoin and Bitcoin. There are still things that need to be done before moving to production though. That (a time frame) all depends on how many people are willing to help, with no expectation of any near term rewards.

Here is a fresh change:

https://github.com/senadj/scrypt-jane

I am yet learning git, so expect a lot of useless commits  Lips sealed
I also have a windows build but I do not know how to upload it yet.
A week or two and I will also have a OSX one too.

It looks like Bter YAC trading works agen. It was not new Mt Gox...  

Also tested deposit YAC to Bter. Works but from pool to real credit in Bter account YAC balance some amount more slow than previously. (yesterday one test and 3.5hour but it is not suprise if thi nk what kind of hassle this all have been)

Also what is surprise Bter have returned (small amount) of BTC's. (under 10% at this first phase and it looks like they try return all....  if they really can recover and build all agen and even better than previously and peoples get (slowly) back loosed BTC's it is really nice and it also give really strong signal that Bter is not what ever bullshit exchange  )

BTER facts :
  • cold wallet was compromised
  • china based (remember china's attitude against crypto and even human rights?)
  • based on an address on the British Virgin Islands (shady again)
  • trades anything that gets to their hands (dead chains, risky experimental chains, whatever)

This is a recipe for disaster AGAIN.
TBH, I wouldn't keep anything of value there.

What's the current enthusiasm for implementing Yacoin support in Open Bazaar? https://openbazaar.org

Are they open to coins other than Bitcoin?

I think it might be good for testing as bitcoins can be quite expensive.

I updated the testing code, so anyone that has it checked out will want to pull in change.

Yacoin doesn't share ROI with novacoin, so GetProofOfStakeReward (in main.cpp) will need to be updated in testing version.

Unless/until we implement STAKE_SWITCH_TIME, the code steps through to :1155
I just left the rest of the NVC code to make it easier to switch in the future and to maintain the overall rebase.

I think I set a bounty for an OSX wallet at some point. I can't remember how much it was though. 30k perhaps?

I'm very interested in renting any scrypt-chacha hashpower that people have to offer, please contact me ASAP in PM.

Looking for days at a time, I have no problems pre-paying or getting you set up.

I don't mess around with time or payment and that benefits all people involved, PM me if you are interested in earning more than you are now.

When priced at 100$, 1$ would get destroyed with each transaction due hardcoded 0.01 yac transaction fee. Who would transact in amounts smaller than 10$ if one tenth would get destroyed with each transaction? I believe this rule in a way serves as limitation for maximum future price. My guess is that it could hardly get above 25$ per yac (25 cents destroyed with each transaction) and more reasonable target value could be between 0.1 and 10$.
I am aware people were paying high transaction fees when btc was at it's high, but that amount did not get destroyed.

Priced at 0.1$ YACoin would now have 5$ million market capitalization. Compare that to current Litecoin market cap (62$M) you can see how small "the push" must be to get us there.

And all that presuming dollar and other fiat money would preserve it's value:)

Is this true? I agree, it needs to be addressed and fixed.

...

This is by design and it is intended to prevent blockchain bloat/spam attacks.
Removing that would cause far more harm than good. It is just something to keep in mind when projecting future value because it serves as a powerfull weight from above. I mentioned it because it is related to what I will write later.


Next:
In order for all willing participants to generate interest there has to be enough space in blockchain to accomodate their PoS blocks. Yacoin with it's one minute block target (~1440 blocks per day) leaves enough "slots" for 720 PoS blocks considering current "no two consecutive PoS blocks" rule. That is - if miners allow it and they don't refuse to mine on top of PoS blocks in order to maximize their profits with up to 720 additional PoW blocks per day.
Leaving that aside, we get to 262800 (=720x365) honest stakeholders with one wallet each, generating interest once per year . If each stakeholder opens his/hers wallet once per month, than we get to 21900 (=262800/12)  - let's call them individuals who were able to generate interest every month this year.

Now what happens, if there are more participants or we all divide/split wallets so thay generate PoS blocks with higher frequency (as we all do now)?
Eventually those 720 "slots" per day will get used and from then on PoS blocks with higher consumed coin age will replace those PoS blocks with lower values at the tip of the chain.
This will lead to high amount of orphans, and it will also cause some small stakeholders not being able to generate interest in reasonable time, because even if they find PoS block, there's a chance it will get kicked of the tip of the chain by richer stake miner with higher coin age.

Someone with bad intentions and big wallet could split his funds and create many many PoS blocks so he would occupy most of those "slots".
And it would cost him nothing to do that (except being online and leaving wallet open).

Here I am only exposing one side of bigger issue with current implementation, because it's crucial to be aware of it in order to understand my proposition.

Other PoS cryptocurrencies with higher block spacing (less blocks per day generated) will have this issue manifested even more, and soon enough only richer portion of stakeholders will manage to generate interest simply due their higher coin age and lack of enough free "slots" in blockchain.

This is PoS issue in general and it was designed that way for security purpose ...


EDIT: ...
My previous post wasn't ment as a speculative investment hint, but I am using it here as input. Considering it's content, I would contend we should raise minimum stake amount, so that no less than 1YAC is generated with each PoS block. That means someone with 20 coins ( = ~2...200$ according to my presumptions from previous post ) could generate 1 PoS block after 1 year. Currently coin age growth is capped at 3 months. This cap would have to be raised then, but another security feature should be added.
We could make PoS hash function result dependent not only on coin age, but we could also amplify N factor when dealing with blocks holding smaller coin ages thereby increasing resource requirements.
In addition to that, consecutive PoS blocks could be made possible again, if subsequent PoS block would fit much stricter criteria, for example exponentially larger coin age plus higher N factor.

I am talking about refactoring of PoS system, so that it becomes more resource demanding. Then we need to give PoS blocks back trust value that is higher than PoW block value. This value could be somewhere in the range of 2-1000x ( = f(coinAge,Nfactor) ) of average PoW block value. It should be high enough so that miners wouldn't ignore PoS blocks and build their PoW-only chains for maximum profit.
In addition to that, PoW difficulty should step up incrementally when there are no PoS blocks near last n blocks. Every PoS block would bring next PoW difficulty back to lowest allowable level. That would discourage PoW miners from ignoring PoS blocks.

Theoretically YACoin is already less vulnerable to PoS issues than other hybrids, because each hash consumes 16MB of memory now (and soon 32MB). It is not so simple to just create thousands of wallets and than build a PoS only chain, because it takes some time (and memory) to hash 1000 scrypt-jane hashes.


This is just an outline of my idea. It is in no way perfect, but I had to get it out Roll Eyes

Many other coins have been shown that a high PoS rate contributes to their success and attractiveness as an investment for example Maieuticoin gives 2014% PoS and holders of this coin make a nice little income just from PoS minting.

Will Yacoin developers ever consider increasing the PoS% (say as N factor rises) or is it forever going to be 5%?

Senj is a Yacoin developer... and is considering it above your post Smiley

I would say anything < 20% is certainly feasible

Although the other mentioned coin is PoS only. Yacoin has both PoS and PoW inflation to consider.

Would increasing the PoS to 6% at the next N factor jump be something to consider?
