I am worry about compress data blocks would slow down the performance of bitcoind and router.
Now, my router is loading is about 4.x average
The old blocks and transaction data are compressed, i dont think, a full node is reading old data so many times. And though if sometimes need an old block read, the performance is not so bad, but you save ~20-30% disk space. And the blockchain site is doubled over a year.

You can compress and store the blocks files in a SquashFS file, and merge it with overlayfs to daemon directory. my ~36G data files requred ~26G space.

Once, if i got time, i will write a howto for linux.  Undecided

Is it possible to implement, blocks found by user, and at what time they were found?

So if im not at home, i just check my statistics, and see if i found a block or not.
Also bestshare option, would be great...
Add your mining address in blockchain.info as watch-only address, they send mails when you receive something.  Roll Eyes

the pools didnt switch to new wallet, so they used the old retarget algo, and mined the 73000, 73001, ... block with wrong diff.
the new wallet with kgw doesnt accept 73000 block (fd063b4d97a2f1f36caa5819fb0336775ed68b34d4f310087817c8c813016697):

Wallets in 75684 block height are on wrong fork.

So I switched back my pool to 73000.

Please use this link to the updated source code:

Thanks

Just few suggestion for new code:
 * reformat the source in KGW function. i mean space indent, not tabs. {} in newlines, etc.
 * You dont need the "if" here, because kgw only run if height > 73000:
Code:
if (BlockReading->nHeight > 73000) LatestBlockTime = BlockReading->GetBlockTime();
Just use this:
Code:
LatestBlockTime = BlockReading->GetBlockTime();
* Same this, you can remove the if (nHeight > 73000) check :
Code:
        if (BlockReading->nHeight > 73000) {
            if (PastRateActualSeconds < 1) { PastRateActualSeconds = 1; }
        }
        else {
            if (PastRateActualSeconds < 0) { PastRateActualSeconds = 0; }
         }
(and else branch can be removed, it is never run, because height is always higher than 73000)

Hi,

Could you please add a getbalance api call to Credit API? I want to add xapo to my minifaucet script. I know v1 api will be deprecated, but faucet owners want to use xapo as wallet provider.

Nah, pool status is displayed, if there is a working api on the pool:
the worker count and the hashrate

Great to see you've included our pool http://pool.digitalgold.co. If you provide me with an address, I'll send you some Tittiecoins  Smiley
Already added. and PMed.

EDIT*  pretty cool but maybe coin dificulty or maybe a list of all coin sand current diffs that'd be boss here is why : people are looking always for low diff coins to solo and hold til price goes up
Unfortunately, i havent big server farm to run the daemon for every coin. So this need to handled other way. The current usecase, if you found and like an old coin, you dont need to try all (not working) pools from bct ann thread (1, 2, ...), instead you look up this site, and find the working pool.

The next milestone is query some info about the pool over api, this helps to avoid empty pools or balance the hashrate. I will figure out how to get the durrent difficulty for coins.

i sent u about a dollar
Thx.

DMD is groestl not SHA
Fixed.

Hi,

This is my new little project: http://www.poolscanner.tk/

It is a pool list website, which is scans the pools and display:
  • if the pool site is online
  • if the pool stratum is available

You can choose an algo, and search for a coin name.

New pools and coins are added continuously.

Future plans:
  • Registered pool owners can add their pools
  • Fetch some stats from pool's api

257  Alternate cryptocurrencies / Altcoin Discussion / Re: universal address+privatekey generator software ? on: March 10, 2015, 01:09:31 PM
you can find the public address type of most coins easily in their source under base58.h around line 270-ish


Example https://github.com/urocoin/uro/blob/master/src/base58.h#L275
Quote
  PUBKEY_ADDRESS = 68, // Uro addresses start with U

you can use a vanity address generator to generate a private key / public key combo for any altcoin you know the "PUBKEY_ADDRESS" it searches for a prefix you define (start of address)
https://bitcointalk.org/index.php?topic=25804.0
link to .22 software https://github.com/downloads/samr7/vanitygen/vanitygen-0.22-win.zip
source https://github.com/samr7/vanitygen

Simple way to use vanitygen in windows:
unzip the download
create a new text file in the same folder

Quote
vanitygen -i -X 68 Uro

save the file as Uro.bat (select all file types)
click on the batch file, a window will pop up and your cpu will search for an address starting with Uro

What is -i and -X ? common flags for vanitygen include:
-i    the prefix search will look for a match not paying attention to capital or undercase letters
-X   sets the base 58 version byte, different altcoins use different so their addresses start with a specific character
-k   keep searching for more matches after onen has been found
-o   set a file to write an output of this match to, example
Quote
-o found.txt
will create a text file called found and dump the result(s) there

theres more but thats the basic

good luck.

for shits n giggles i made an address for each base 58 version so i could put it into pools for payouts without needing a wallet yet.


(best practices, you can use an old computer not hooked up to internet to get some quick easy addresses. you dont need to make a specific address for it to be secure.)

(i dont know about nxt or crypto note vanity generators)

This is good, if the coin use sha256 hash for address checksum. If the coin use the own hash algo for that, i cannot generate address nether with vanitygen nor with "universal" paperwallet.
Just if the coin owner implemented the algo for own paperwallet, than that sould work.

anyway, here is my universal paper wallet (just for sha256 checksum address) : http://www.universalwalletgenerator.net/
