[200BTSX] tool to convert bitcoin public key into BTSX/PTS address

[xeroc]

Here we go:
https://github.com/BitShares/bitshares_toolkit/pull/734

edit: just figured I need to distinguish between compressed and uncompressed format .. thought they where only for private keys ..
sth learned to day .. maybe I can figure that out too

[xeroc]

I think i got it .. gonna have to test it first .. publish code next week ... have a nace weekend

You cannot "generate a pubkey from a bitcoin address" because the address is essentially a cryptographic hash of the pubkey. Cryptographic hashes are one way - it's easy to compute the hash for a key but close to impossible to find the key(s) generating a given hash.

I know that .. fixed the typo above
I want to generate a BTSX PubKey from a BTC PubKey!

[pc]

but there is no way to convert an address to a public key (address is hash of public key)

Is it even possible to to register a btsx account using a pubkey generated from a bitcoin address .. so that the holder of the privkey (bitcoin) can import an account name I registered for him?

BTSX addresses are not used anywhere in the API...  we use the public keys for the accounts, but there is no way to convert an address to a public key (address is hash of public key)

I tried to figure this out .. but failed ... could you points me to some direction so that I can try figure this out myself?

I don't think this can work.

BM, how does the toolkit generates the balance id from the existing btc/pts address in genesis block?similar to the following logic？ is  the balance id same with balance record owner ?

balance id =ripemd160(sha512(hash of public key))

The initial balances it stored in a BTSX ADDRESS .. the rest of the network works on BTSX PUBLIC KEYSs (ie, when you register a name, you register a pubkey .. not an address)

Thus, I cannot use the result of the above script to register a name on his behalf as I need to register a PUBKEY ... so I need to take the bitcoin pubkey of that address and convert that one to a bitsharesx pubkey ... just don't know yet how to do it

So I cannot register a name on the above results ...

can I convert a hex.formated bitcoin pubkey into a BTSX pubkey so that I can register a name on a bitcoin pubkey/address ?

Code: [Select]

#include <bts/blockchain/address.hpp>
#include <bts/blockchain/pts_address.hpp>
#include <bts/utilities/key_conversion.hpp>
#include <fc/crypto/elliptic.hpp>
#include <iostream>

using namespace bts::blockchain;

bts::blockchain::address btc_address_convert_to_bts_address(const std::string& base58str)
{
 return address(pts_address(base58str));
}


int main( int argc, char** argv )
{
 if( argc == 1 )
 {
  std::cout << "useage: convert_btc_address <btcaddress>" <<"\n";
 }
 else
 {
  std::string myarg = argv[1];
  std::cout << "Input:       " << myarg << "\n";
  std::cout << "BTS address: " << std::string(btc_address_convert_to_bts_address(myarg)) << "\n";
 }
}

But it is not working as intended

I generated a random new key and added it to an existing account ... result

[xeroc]

nice solutions so far ...
As I am not a coder (and I figured those parts out my self already)
I'd really like to see a full-length compileable file ...
(from within the toolkit)

(best for me would be a git pull request to the official repo that includes that file in the utilities of the toolbox .. )

edit:// and I figured 200 BTSX is to few for that task ..
I will send both of you the 200 BTSX and as soon as I get to it I will raise the bounty price to sth. that is more like 40-50$ ..

bts::blockchain::address btc _address convert_to_bts_address (std::string& ptsbase58str)
{
return address(pts_address(ptsbase58str ));
}


i write this with my phone, not test yet.

[cgafeng]

   string client_impl::btctobts(const string& btcaddress)const
   {
      balance_record initial_balance(pts_address(btcaddress),
         asset(share_type(0), 0),
         0 /* Not voting for anyone */
         );
      return string(initial_balance.condition.get_address());
   }

this work on client.cpp.
