General Discussion / One possible attack to POS mining
« on: March 11, 2014, 03:55:11 am »
Please correct me as I'm not a native speaker and could have some wrong understandings.
Suppose I'm a bad miner, what can I do? I can
1. Exclude some transactions. This doesn't harm much as I can only make few attacks in a short period of time. In fact, you can't even tell whether I'm a bad miner excluding some transactions or I'm a good miner who hasn't received the transactions yet.
2. Roll back some transactions by rolling back some blocks. This is interesting. But how can I do that?
Well, I need some percentage of shares. Let's say I have 10% shares. As the yearly inactivity fees exist, most of shares will have (maybe much) less than 365 coin days. I can easily accumulate my coin days to 50% by not destorying the coin days for 5.x years. Using the coin days I accumulated, I can roll back a large number of blocks. The number can be really large (like 100) as I have 50% of coin days. How many confirmations do you need to feel safe for a transaction? 6, 10? I would say at least 100. Considering I can choose time when large CDD happened one day before and the diversity of the shares, the percentage of shares I need will be much less.

BitShares PTS / Re: PTS Withdrawl from BTER not arriving in wallet!
« on: March 02, 2014, 04:59:34 am »
OK.

So, I just received my PTS in my wallet from BTER after almost 48 hours of getting the confirmation of the withdrawl from BTER.

@freeworm: So now you will credit my BTER account with the PTS_S? As of now I do not have it.

Thank you for your attention to the matter.

I also got my PTS to my wallet from BTER and I would have the same request to @freeworm for PTS_S.

2) Increase default collateral requirement to 10x.

About 10 times the mortgage:
If I have 400000 xts. I can do: continue to buy bitusd, when I buy a value of 300000 XTS bitusd, the 2700000 XTS is frozen. Next, the seller has no xts. I began to raise the price, the price increased to 1.3 times, let the seller liquidated, sell him my bitusd.
If so, the bitusd deal is not fair. XTS is easy to be short. Perhaps the only fair trade, buyers and sellers of the half, 2 times the mortgage.

关于10倍抵押的思考:
假如我拥有40万xts。我可以这样做:持续买进bitusd,当我购买了价值30万xts的bitusd,卖方就有270万xts被冻结。接下来,卖方已经没有xts了。我开始抬价,把价格提高到1.3倍,让卖方平仓,我的bitusd卖给他。
如果是这样,bitusd的交易是不公平的。xts容易被人做空。可能唯一公平的交易方式,买卖双方各出一半,2倍抵押。
具体抵押细节我还不清楚,只是推测,如果说错了,请谅解。

"when I buy a value of 300000 XTS bitusd, the 2700000 XTS is frozen." is not neccesarily the case. If I buy 1000 bitUSD which is backed with 1000 XTS. Then I sell it at 30000 XTS to you and you can only buy 10 bitUSD which is backed with 10 XTS.

BitShares PTS / Re: PTS Withdrawl from BTER not arriving in wallet!

I was told that they will credit the PTS_s for all the withdrawls which didn't go through before deadline. Since they haven't re-enabled trades and deposit/withdrawl I assume they are still working on it.

The problem with PTS withdrawl on Bter is that they put 0 transaction fee, even though they take an eye watering 0.1 PTS withdrawl fee. This is just plain greed. My withdrawl has been in limbo for 37 hours now.

How did you check whether you have the withdraw transaction? I checked with https://coinplorer.com/PTS/Addresses/<my wallet address> and don't even found a transaction with 0 confirmation.

Actually the trades has been re-enabled about 1 hour ago. So I was disappointed to see nothing in my PTS_S, PTS account nor PTS wallet.

but in case they weren't confirmed before the PTS snapshot, Bter will obtain the BTS for you.
Yes, but at latest when will that happen? I haven't seen my PTS_S in my account on bter.com. How do you check whether the transaction is confirmed before the PTS snapshot or not? I don't see my pts transaction either. So at least for the moment, I've lost both my PTS and PTS_S.

Hi Dan,
0.5.5 works for me too. Thanks for the update.

0.5.4 still doesn't work for me but it's ok for me as long as the public key and founder code is correctly registered on the server database and will be included in the genesis block.

Yes, "john" is properly registered in the database with 5yQRwuHnu9iRF4NuzvcDaDwgZch74EVT6X8b4pfecrwbnnMTLF, so your id will work properly show up as a Founder ID once the blockchain is initialized.

Another user reported a similar problem today, so I reviewed the code today that reports the points and I'm pretty sure I know the problem: for security reasons, the name server requires that the identity be created with the "Founder Code" in order to report your points (basically Keyhotee sends the KeyhoteeID, the public key, and the founder code to the founder registration server to be verified). I suspect that your identity info is either missing the founder code or it has the wrong one. You can check the founder code entered by looking in the "Notes" section of your contact info for your identity. If it's blank or if the code is wrong, this would explain the issue. Note this doesn't mean your Founder Id isn't registered, just that it won't show as registered in your Keyhotee until the blockchain is initialized.

I'm going to look into a possible method for notifying anyone who might be experiencing this problem today, and I'll report back with more details late tonight or tomorrow.

Thanks for the clarification. I'll wait for the blockchain. Is there any other way for me to recreate the identity with founder code or add founder code to the existing identity?

I also have the issue of showing as "unregistered". Can you have a check for me? Thanks. My public key is "5yQRwuHnu9iRF4NuzvcDaDwgZch74EVT6X8b4pfecrwbnnMTLF" and the founder id should be "john".
Where those points are it says "Unregistered" on mine. But it still says "Keyhotee Founder" beside it.
The Keyhotee Founder message is not meaningful in this case, it just means you "mined" your name locally in a temporary blockchain, probably using one of the early betas before identity mining was disabled.

The important thing is the points message, which apparently is not showing properly on your client. On the founder server, I see JustHayden has been registered with a public key like this: 6ked...V6Bb.  Does that match the public key shown in your KH client?

Also, are you using the 0.5.3 alpha client?
If possible, please reply to me via dan at syncad.com to speed my replies.

Keyhotee / Re: Keyhotee Founder ID Registration Process
« on: January 05, 2014, 12:59:09 am »
I checked the register when creating new identity and it shows as 'unregistered'. Seems like I shouldn't check the checkbox. Then when I try to claim the same id it says 'registered with xxxx points'. Does it mean that it's registered successfully? If not, how can I solve this?


Hi, I created my identity but forgot to check "register", and now in the contact my profile shows "unregistered" and highlighted as yellow.
any comment on how to solve it? is it a big problem?

The register checkbox is for IDs that you want to mine once we launch the blockchain.  If you saw your USD contribution in the Status then you are OK.

I also forget to check "register", and can't see my USB contribution in the Status. How can I fix it ?

I remember the profile thing except brain wallet key is optional. But The applications seems treating birthday and name as mandatory. If I specify something in name and birthday and later when I try to recover the master key, should all the information perfectly match to generate the same master key? I really don't want to remember too many things and the only thing I want to use is the brain wallet key. Is it possible?
