Hi,

I am working on a Bitcoin testnet exchange; it is for fun mostly and would appreciate to get more testnet coins than what existing faucets release per day.

How much do you need?

10 tBTC would suffice. Thanks!

Re: Don't buy "wallet.dat" files with lost passwords. EXCHANGE THEM!

Why would anyone sell a wallet with a huge balance for a low value, ask yourself an obvious question like that, answer, they wouldnt.

I don't know exactly. I received 1900 files with balance for free and it take me 6 weeks to find out that minimum 300pcs is 100% fake.

Akaron, could you please share those wallets with me?

bitxchg at gmail

You'll get 1/2 of any wallet I open

Can I please get validated wallets to check myself and give a second opinion?

Using pywallet dump and comparing blockchain transactions as well as testing which can actually be opened in Bitcoin Core or the ones which can be salvaged, I can say, after quite a bit of effort I put into this, that there aren't many shared bitcoin wallets (no surprise actually), wallets worth trying to crack the passphrase.

If anyone has the ones the thread author refers to as validated, please email me at

bitxchg @ gmail . com

and I will provide my own analysis of their authenticity and secondly, reward whoever shared them.

Good luck guys!

Re: "Why I'm releasing a brainwallet cracker at DEFCON 23"

This tool is supposed to be working for Ethereum too.

I did a quick test for the now famous tongue twister expression 'how much wood could a woodchuck chuck if a woodchuck could chuck wood'

sha256= b09c765fa3dc6ad138a8d0da17cd94306fbc32acb3d67bc093936861ccc48769
ETH address= 0x757B03C889B997fe78791417a230463eBBc09182

I have created a bloom filter from a file in which I inserted the ETH address (0x757B03C889B997fe78791417a230463eBBc09182)

Code:
/usr/.bin64/bf/hex2blf eth_addr.txt eth_filter.blf

Then I run this command which returns nothing:

Code:
echo -n "b09c765fa3dc6ad138a8d0da17cd94306fbc32acb3d67bc093936861ccc48769" |./brainflayer -v -c e -b eth_filter.blf
rate:     64.05 p/s found:     0/1          elapsed:    0.016 s

I would really appreciate if you'd tell me what am I missing, as I am pretty sure the help is indicative that it also support Ethereum processing?

Code:
./brainflayer -h
Usage: ./brainflayer [OPTION]...

 -c TYPES                    use TYPES for public key to hash160 computation
                             multiple can be specified, for example the default
                             is 'uc', which will check for both uncompressed
                             and compressed addresses using Bitcoin's algorithm
                             u - uncompressed address
                             c - compressed address
                             e - ethereum address
                             x - most signifigant bits of x coordinate

Re: List of all Bitcoin addresses with a balance

You deserve praise for making the list available and keeping updates running.

I am playing with the brainflyer tool and as it requires the hash160 addresses for the bloom filter, I am asking here, in case someone knows and can point me in the right direction, how to convert the ~430K bech32 addresses with a positive balance currently, to hash160?

Decoding base58 to hash160 is pretty straight forward (python) and is done in 1 line  'adr160 = base58.b58decode_check(adr58).hex()[2:]'

# python3 b58decode.py 34xp4vRoCGJym3xR7yCVPFHoCNxv4Twseo
23e522dfc6656a8fda3d47b4fa53f7585ac758cd

But I can't figure it out nor I could find some good example for decoding bech32 to hash160.

bech32 address (start with 'bc') : bc1qxv55wuzz4qsfgss3uq2zwg5y88d7qv5hg67d2d


Any thoughts?

Re: is CEX.IO a SCAM?
by

on 12/01/2018, 21:24:58 UTC
CEX.io has stolen my money as it appears so far.

I have account up112960293 and in December I have changed my phone and in the process I lost the 2FA app and I can't log in.
Guess what ? This played very well for cex.io as they probably have major liquidity issues !!!
I have opened tickets 574201, 546283 and others and they respond to these tickets usually in a few hours saying that it will be processed shortly and I need to send documents and proof I am the owner of the account which I kept sending again and again.

No response !!! and I am locked out for over 20 days now.

I guess this is the perfect scenario in which they can spend and use my funds w/o really any issue while I can't login to my account.

In the crypto world of millionaires I gues $2500 is nothing but hey, that's a deposit that I made from my salary and... there are no millions there.
I feel scammed and tricked but in the same time powerless to do too much.

Any advice of what I can do now from anyone?

Who knows if the balances_498754.csv file shared above contains the compressed or uncompressed format of the bitcoin public address?
