Its an IRC webchat. You could simply point any IRC client to #angelshares in freenode.net if you dont want to trust that link. irc2go.com is quite a trustworthy site tho.

I plan to purchase some ProtoShares, now if i buy them am i automatically going to be allocated ANgelShares ? or do i need to donate some protoshares to get angelshares ?

Yes you need to donate Bitcoin or Protoshares to get Angelshares. If you are after Bitshares its a good deal.

Technical Support / Re: How to encode a PTS address?
« on: January 03, 2014, 09:04:38 pm »
Ok yeah that script seems wrong. Let me try.

Code: [Select]
asm_hash = "your_hash"
extended_hash = "34" + asm_hash
binary_extended_hash = extended_hash.decode("hex")
double_hash = hashlib.sha256(hashlib.sha256(binary_extended_hash))
checksum = double_hash[:3]    # first 4 bytes
binary_address = binary_extended_hash + checksum
pts_address = b58encode(binary_address)

You might have to insert some prints to see make sure I'm converting between strings, hex, and binary correctly, and adjust accordingly. If you put a print after every line and show us the output we can try to help debug.

toast, i really appreciate your help, but the original script is exactly doing what i want. your modified script is encoding correctly the wrong hash.

Code: [Select]
# this is the <sig pupkey> asm hash
script = "304402205e81e8ed0b1f7cf6d1d415961859d3b95f5e5c353af303b6cef1e3efa6c3349702202fa9fdd6914abd0e9606c78899e7f3010cafdad211645cf459ae18b3b827b2c101 0365e0beb9a0c1497f3667067aeb8f3ea9dc4c9d5696cee7f19eae49f9457a5cfb".split()

# this is the extracted pubkey
pub_key = script[1]

# this is the binary pubkey? (why is it called 'decode'?)
binary_pub_key = pub_key.decode("hex")

# thats a sha256 performed on the binary pub key
h = hashlib.sha256(binary_pub_key).digest()

# thats generating a new ripemd160 hash, isnt it?
ripe160 = hashlib.new('ripemd160')

# no idea whats happening here?
ripe160.update(h)

# no idea whats happening here?!?
d = ripe160.digest()

# the d is what I want to get, from here I know!

BTW the GPU miner works on mmcpool.com I got told, all you need to do is edit your /etc/hosts and add:
Code: [Select]
148.251.6.201 mmcpool.1gh.com

The only exchange
You can buy MMC on buymmc2.com, but to sell there's no other place yet

The guys on buymmc2.com also buy.

Le me know if this helps. I may be able to be more helpful if you go back a few steps and explain where you got your original "ASM hash".

This is the ASM hash in the code below:
Code: [Select]
script[1] = 0365e0beb9a0c1497f3667067aeb8f3ea9dc4c9d5696cee7f19eae49f9457a5cfb
And thats where I'm stuck.
This is where the python code starts, assigning the string to the variable "script". I cut some unimportant stuff.

Code: [Select]
script = "304402205e81e8ed0b1f7cf6d1d415961859d3b95f5e5c353af303b6cef1e3efa6c3349702202fa9fdd6914abd0e9606c78899e7f3010cafdad211645cf459ae18b3b827b2c101 0365e0beb9a0c1497f3667067aeb8f3ea9dc4c9d5696cee7f19eae49f9457a5cfb".split()
h = hashlib.sha256(script[1].decode("hex")).digest()
ripe160 =  hashlib.new('ripemd160')
ripe160.update(h)
d = ripe160.digest()

This just takes the pubkey and assigns ripemd160(sha256(pubkey)) to the variable "d". The rest of the code is pretty easy to match up with the diagram I linked above.

What is h exactly? I wasnt able to reproduce this.

I will keep the OP updated.

Come on, it is going to happen. But I think it is about as hard to RE the miner as it is to write an original one. Besides, implementing one gives the invaluable experience, while reverse engineering gives basically nothing. And, supporting the thing is even harder, let alone running a pool under high load. GL to anyone who tries, you've been warned :)

I agree. And in addition, decompiling is not the same as reverse engineering :)

Everyone had the chance to vote me to buy the miner, but that didn't happen  :D

Good idea. I was trying to parse the MMC blockchain today to reproduce the votes but failed decoding huge supertransactions (>2M).
