Why is so slow?

Hi!

Hi,

it seems you have not enough memory (RAM)?

SEVERE: Error cleaning up after reference. java.lang.OutOfMemoryError: Java heap space

[plaber]

How can you rich 2000 k keys/s on rtx2060, i made database from http://addresses.loyce.club/?C=M;O=D this file, so it 2gb size db, i have 32gb ram, and when i run run_Find_1OpenCLDevice, all my ram go to use, and i have 1062 k keys/s with ~30% cuda load and 100% load of my i5 9400 cpu

[bernardladenthin]

Hi, your CPU limits the keys/s. The SHA256 and RIPEMD160 will be done on CPU and this might be solved in future. But it needs to be implemented and is a complex problem.

[plaber]

plz add example with Key range, what CPU do you use?

[bernardladenthin]

CPU is AMD Ryzen 9 3950x. Key range of 160 is enough to scan every possible address.

[plaber]

You writed:Key range A key range can be defined (e.g. 64-bit) whereas the first (e.g. 192-bit (256-bit - 64-bit)) are zeroed. This can be used to creaty keys in a specific range to find keys in a known range (e.g. Bitcoin Puzzle Transaction). This can be also used to proof that the software works.

So i added 1GL148eHmksSwjo4cVEicCGTfyGDBSbakY to wallets and i want to start random generation from 5K8AFtY1ikpCTESEM7u2ywEA9CDV1HBTkYEd2iB9Zg8j8Krppo8 for example ( i got this key pair here https://keys.lol/bitcoin/608786848605066771695207212229659213228862548324147378430462746829474617469) to proof of work

[bernardladenthin]

Hi,

key generation within a specific key range is not supported currently. The range is meant to be in bits and not for a specific private key start value. But I can try to implement this feature soon.

[plaber]

for example in python i doing like this

test_hash = '1MueGqjgebb2HgxbCGVEfm4zfUptenExPj'
test_key = '5JgZf6s3CpSxBkhgDWDbMS3UJ55E95axdh2Ma8uDusttAyRqNDX'
    # add test hash to db
    test_hashb = base58.b58decode(test_hash)
    lset.add(test_hashb)
    while True:
        i += 1
        priv_key = os.urandom(32)
        if i == 1:
            # set test key
            test_keyb = base58.b58decode(test_key);
            priv_key = test_keyb[1:-4]
...
        if pub in lset:
            if i == 1:
                sprint (r, kek, ' test passed ---- ' +dt.datetime.now().strftime('%Y-%m-%d %H:%M:%S') + ' ' + pubd + ' ' + priv[:10] + '...' + priv[-10:])
                start_time = dt.datetime.today().timestamp()
                continue
            print ('WINNER WINNER CHICKEN DINNER!!! ---- ' +dt.datetime.now().strftime('%Y-%m-%d %H:%M:%S'), pubd, priv)

so just decode base5 and cut first and last bytes to get 32bit hex private p.s. this python script give me 300M keys for 8 hours of work, your script give it for 2 minutes

[bernardladenthin]

I've added the idea of setting a key range to future improvements.
