Nice streak of NMC blocks!

Could we do it also with BTC blocks?   Wink

Great news!
So while you take a little bit more risk - it should drive the prices much higher

It is interesting that the price is now moving higher still (currently 0.106). I guess the long term prospect of the dividend is worth it? Selling at a premium of 2.5 dividend payments.

For a perpetual it would be worth it, but with Goat having the option to call this in at short notice (1 or 2 weeks from memory), they are taking on a bit of redemption risk.

Yeah. They are taking a risk and really I'm shocked to see some of these prices. But it is a free market (other than Nefarios random regulations, more about his newest one later).



I guess it's because the fact that the contract on GLBSE states "tests" and the security has the word bank in its name - so it's a bit misleading as you can understand it as investing in institution instead of depositing money.

I think p would need to be the weighted average price to be fair to the issuer. It will mean that some buyers still lose, if they paid more than p, whereas others would gain, if they paid less than p. Using a weighted average, rather than a simple numerical average, will ensure that amount gained by winners = amount lost by losers and the issuer is no better or worse off.

yep, you are right
I meant average of all sold bonds (see my exapmle) which is weighted average if you take pairs (price, number of bonds sold for that price).

Sorry, my mistake - I did put the formula down quickly and I didn't check it well.
The idea is that in case of buy back they would pay the auction average price. And in the following 28 days it would always rise by 1/28th of (1.28-p) so it would be 1.28 on the maturity day.
So the correct formula should be:
p+(1.28-p)*x/28
so for x=0 we get p of what? p = average price of bonds sold in auction
and for x=28 we get 1.28 I am assuming with a p of 1.00 BTC with any p

This makes more sense now
nice table
x - number of days since auction (columns in your table)
p - average auction price (rows in your table)

eg:
1000 bonds sold at 1.09, 500 bonds sold at 1.12 gives us an average price of p=1.10
if they are bought back after 14 days (x=14)
the buy back price would be 1.10+(1.28-1.10)*14/28=1.10+0.18/2=1.19

In the event that BS&T stops payments or changes its terms and conditions so that the intended pass through of interest is either stopped, pays lower interest or at a schedule that does not align with PPT bonds, PPT reserves the right to buy back the currently issued bonds by paying the coupon (currently 1% per day, accrued, simple interest) to current holders.

2.  In the event that interest payments from BST is below your expectations then PPT can buyback the bonds at 1% per day on the initial bond listing price of 1.00 BTC per bond.


The wording was intended to be tighter than simply "below expectations".  It is to cover the event where Pirate stops and winds up the whole thing, or changes the interest rate scheme materially so that we cannot pass through the intended 1%/day rate.  It does not give us the right to issue the bonds on day 1 at a premium and then immediately buy them back.  

Well defaulting is probably taken into account by everyone's risk appetite.
But this thing of early buyout will drag the bond price down during bond auction and also later on secondary market as the probability of change in the conditions of BS&T is high. What about changing it to p*(1+0.01x)/1.28 instead of 1+0.01x where p is the average price in the auction and x number of days since auction. I understand that this would push you to invest more than 1BTC per bond sold into BS&T which I guess wasn't originaly intended. Take it as suggestion that might bring auction prices higher and thus increase your profit.

buy back price = p*(1+0.01*x)/1.28,

where p is 1.00 and x is 0

In the event of BST changing the interest rates lower that triggers the event, the bond buy back price would be:

1.00 * (1 + 0.01*0 ) / 1.28 = 0.78125

Am I missing something here?  This will always have the effect of lowering the bond price because in the case of a drop in the BST the bonds will be called at the p*(1+0.01*x)/1.28 buy back price and the bondholder will always lose money on the bond.

You think 1+0.01x would keep the bond price low, p*(1+0.01x)/1.28 is even lower.

Here is a whole table.  The buy back price is in the matrix for its respective p and x value.

...

What would increase the price of the bonds at issuance and thus lower the return to bondholders is if the issuers took on more risk.  The higher the risk then the higher the potential return should be.  The issuers would need to guarantee the daily 0.01 increase in par value up to 1.28 BTC.  If there is a lowering of interest rates by BST then the loss of value by the PPT team would have to be made up with the insurance deposits that PPT keeps.

Other than that I think the current plan is sound.

Sorry, my mistake - I did put the formula down quickly and I didn't check it well.
The idea is that in case of buy back they would pay the auction average price. And in the following 28 days it would always rise by 1/28th of (1.28-p) so it would be 1.28 on the maturity day.
So the correct formula should be:
p+(1.28-p)*x/28
so for x=0 we get p
and for x=28 we get 1.28

Are we still connected to the BTC/NMC networks or do we run the shifts just for fun?  Wink

stochastic caught me on this as I didn't do my home work to check the formula
the idea was to get p after auction (x=0) and 1.28 at maturity (x=28)
the correct one is: p+(1.28-p)*x/28

Wow, this is much better maybe we are out of the tunnel!
Although we just barely keep up to the expected average for the last few days ... to offset the 5 weeks of bad luck we will need much more ... but this is definitelly good start!
150  Bitcoin / Pools / Re: [120 GH/s] BitMinter.com [Zero Fee, Hopper Safe, Merged Mining,Tx Fees Paid Out] on: March 17, 2012, 12:20:50 PM
The bad luck streak is continuing ...
For the period of last five days we were expected to find 7 blocks on average but we found only 3 ...
Seems that -30% became standard for this pool now. :-(

I noted that there is again missing record (no. 729) in the blocks list.
DrHaribo are you sure thare is no flaw in the database which could cause us loosing blocks? Or some one got some back door access and gets our blocks? ;-)

This graph at Pool-X (LiteCoin pool) is really nice.  I think you have to login to see it, but I think seeing it is worth making an account.
http://pool-x.eu/blocksAuth

It is a nice graph. It is per block and not per time though, on the X-axis, so it's basically the same as ours. But the Y-axis is number of shares instead of CDF, and they have a running average for the pool shown in addition to each individual block. Might be an idea adding such an average. Not sure about shares vs. CDF though.

DrHaribo did you change anything on the server lately?

Yeah, I changed most of the database stuff in the pool backend. I put in some stuff to make parallel updates safe and added automatic retries in case a database operation fails.

1) some rows are missing from my blocks list: 657, 659-660, 662, 669, 671-687, 689-691, 693, 695-698, 701-702, 705-706, 712

That's due to parallel database transactions conflicting and one being rolled back and retried. When a database transaction is rolled back everything you did is reset to how it was before the transaction started except sequences. When a number is allocated from a sequence the same number won't be given out again, even after a rollback. Already there are many gaps in the user IDs. Now with the new database code there are gaps in the block numbers. Looks a bit ugly. Sad I think maybe I'll switch to not showing the internal ID. The table is also sometimes too wide, so that may help with that problem. Or is a block ID of some sort useful?

2) BTC blocks and NMC blocks don't come anymore in pairs as earlier:
  • when BTC block 170048 was found (row 661) NMC block 45862 is listed 1 minute earlier (row 658)
  • when BTC block 170495 was found (row 688) NMC block 46281 is listed 5 minutes earlier (row 670)
  • when BTC block 170638 was found (row 699) NMC block 46403 is listed 1 minute earlier (row 694)
  • when BTC block 170759 was found (row 710) there is no NMC block listed mined by the same user near by
  • when the last BTC block 170838 was found (row 713) there is NMC block 46572 found by the same user 5.5 hrs earlier (row 711)

170838 was stale on the NMC side unfortunately. I checked the logs and we received a new namecoin block from the namecoin P2P network 5 seconds before we attempted to create ours. Let's just be glad that was a new NMC block just ahead of ours, and not a BTC block.

170495 and 46281 were created from a single proof of work from kjakman. They were created at the same time, but one had trouble getting registered in the database. It took a full 5 minutes from it was created until it was successfully registered in the DB. I was watching and cursing as the database transactions were being retried.

Also this database code is putting 10x to 20x the load on the database, compared to earlier. While that's not a problem for the server, I don't like it. I am already working on a new solution that should run much smoother. On my test server the load was much lower and conflicting transactions happened very rarely. Back to the drawing board!

No payout today?
Although it would be only 0.011 BTC for me this time ... ;-)
Pajka

Did you check your leased shares count?  Pir8 mentioned a purchase interregnum.  No purchases means check your f/o pool.

Yes, I did. For that day it was only small number and thus the 0.011 BTC expected payout. And I guess that he didn't send the payouts because of the small amouts.
I was following the state of my countrs to find out what the payouts are based on ... and to me it seems that the payouts happen around noon NY time based on what was on the account late night/early morning.

DrHaribo did you change anything on the server lately?
Or anybody do you know why this following happend?

Till yesterday always when we found BTC block we found also NMC block and in the list of blocks they were listed BTC and next row NMC both with the same timestamp (eg. blocks 169688/45504 - in our blocks list rows 648-649).
Since then there are two things:
1) some rows are missing from my blocks list: 657, 659-660, 662, 669, 671-687, 689-691, 693, 695-698, 701-702, 705-706, 712
2) BTC blocks and NMC blocks don't come anymore in pairs as earlier:
  • when BTC block 170048 was found (row 661) NMC block 45862 is listed 1 minute earlier (row 658)
  • when BTC block 170495 was found (row 688) NMC block 46281 is listed 5 minutes earlier (row 670)
  • when BTC block 170638 was found (row 699) NMC block 46403 is listed 1 minute earlier (row 694)
  • when BTC block 170759 was found (row 710) there is no NMC block listed mined by the same user near by

I have similar feelings as Antonio has ... is that bad luck bacause of me joining the pool? ;-)
I've directed my hashing power to your great pool month ago ... approx. where the Rewards graph starts today ... and I see that the pool since then generated only 1700 bitcoins instead of expected 2467 which is 30% less ... that's pretty bad luck! :-(

I like the pool and the interface. It's great!
Hope for better luck for the next month! :-)

Anyway I would have 2 suggestions to consider ...
- I'd like to see longer history for statistics as an option (blocks, shifts, ...)
- It would be also nice if the luck and reward graphs could go further into the past (again probably as an option)

Hello, my name is Pavel, I do bitcoin mining for aprox. half a year and I was coming to this forum from time to time but as I didn't need to post I haven't registered till now
Now when I want to post I must say that I'm surprised by this newbie forum restriction and find it quite annoying

Just keep posting (eg. reply to this) to get your post count at 5 or more, and troll the forum for 4 hours.  You'll be out in no time.  I took the day off yesterday to get outta this newbie-jail ;P

Well, seems you are right as even posting to the whitelist request thread didnt help ...
so this should be might 5th post ... and I hope the last junk post in the forum ;-)
156  Other / Beginners & Help / Re: Newbie restrictions on: March 10, 2012, 12:04:25 AM
Well, the newbie restriction is very annoying ...
I posted also in the Whitelist reqest thread but that didn't help ...
So I'm forced to post 5 posts without sense ...
This just makes the things only worse as every new member has to create new junk stuff to become valid member ...
Don't you think that you might reconsider the rules?
Or create "junk" thread where everybody will post their 5 initial posts? ... But then why that? ... :-(

Yes painful but they prbly have a good reason

Well I see one advantage ... and that's the fact that all the created "junk" is located in the newbie section ... ;-)
