Congrats on your 1st place entry. Hope it keeps its position.

The substring is 32nd to 41st characters, hence for yours fdf1648f8. Still some space to squeeze in to the top position.

fdf1648f8 is indeed 68167289080 in decimal.

Why is the main 0.5BTC guaranteed tournament postponed?

We shifted it back when there were 0 entries to allow us more time to campaign for it.

It's not a typo, in common programming language, esp. for .substring(), 1st character is at position 0. 32nd character is at position 31 (starting from 0). Even though the doc is using psuedo-code, we are using JavaScript as the base.

lol. sorry. Grin

I don't have much idea about javascript. But in Excel, entering =mid(31,40) gets me the substring from the 31st place.

Ooops. Oh well, Microsoft...

32nd? Dang! Oh, it is. Can you fix this typo:

Quote

// Concatenate txid, nonce and tournament address
// txid and tournament address are hex strings while nonce is string in integer
composite = txid.toString() + nonce of first confirming block + tournament address;

// SHA-256 it
hash = sha256(composite);

// Get a substring of hash at 32nd to 41st position
// with string length of 9 characters
score_in_hex = hash.substring(31, 40);

// Convert it into decimal
score = parseInt(score_in_hex, 16);

It's not a typo, in common programming language, esp. for .substring(), 1st character is at position 0. 32nd character is at position 31 (starting from 0). Even though the doc is using psuedo-code, we are using JavaScript as the base.

Edit: I checked. Order is correct. Funny I took 32 for almost all the cases.

Anyhow lets say if my position is in winning stage, and then alot entries coming and my position drop out..
Is it possible that entry will back to winning place again if the number of winners increases?

Yes, that is a valid possibility.
If the new entries are mostly scoring lower than yours.

Alright thanks and understood all of it.. because my position just gone.. and check its at no6.. and just checked again. Become no7. Eww its so sad.. too early for celebrating no5 just now.

Hey, you got company.

I am fourth. from second. Cool

...and #1 on the 000 tourney.

Once you get a super high number I think it would be really hard to defeat.

The latest confirmed block (375 464) just just pushed everyone down by 2 spots!

That was me. Grin

Can I send one tx for multiple entries?

Not at the moment though because of the txid.

But it's a feature that we should look at. We shall add support for this with txout index as another scoring factor.
