Hello,
I bought a physical bitcoin
Denarium a year ago in a multisig format. It is a 2-of-2 multisig coin. I have been trying many different methods (for 2 months now) to make a transaction (I would like to transfer my bitcoin to
blockchain.info webwallet).
I tried using:
- Pybitcointools (If trying to push it prints "none")
- Bitcoin Core
- Armory
The main problem is that all the tutorials teach how to create a multisig coin and from there on spend it, but I have no idea how can I spend my coin if the multisig coin was created for me by Denarium [I do have access to all the necessary private keys and public keys, but the main problem (for example with Bitcoin Core is that I don't know how to get a redeemscript) or if I'd like to import my multisig bitcoin to my wallet, what the correct format should be?]
Can anyone help me and/or share me a tutorial on how can I transfer my physical Denarium bitcoin? I have the necessary keys and addresses.
Here is the only tutorial that Denarium Support gave me:
Here are the instructions. It's currently
a bit complex process. We are looking at ways to make it easier in the future.
Download pybitcointools from
https://github.com/vbuterin/pybitcointools/First off, get public parts of your coin from our database. Using M4 as an example:
https://status.denarium.com/coin/#/M4 . The important bits are Public Key and Second Factor Public key.
Then, peel the hologram off from your coin and scan the QR code or type the letters manually to your computer. As an example I have created a private key (yours of course is different: SJER5sBdx4fRnGQ6Kcrwkb2ez8KdNA. This is so-called mini private key, documented here:
https://en.bitcoin.it/wiki/Mini_private_key_format .
Convert mini key to raw private key in hex format with pybtctools: ./pybtctool sha256 'SJER5sBdx4fRnGQ6Kcrwkb2ez8KdNA'. In my case I'd get 1f0e1422bef5f90614f8ce4299f6aa0c1b8900adbfd0e9050e7126b0bb03c7d6 .
Verify that we got the correct key by matching the public key on the web site with the result of the coin. Using my coin as an example, I would run ./pybtctool privtopub 1f0e1422bef5f90614f8ce4299f6aa0c1b8900adbfd0e9050e7126b0bb03c7d6 which returns
049409aa12bd76f6fe8a001d17a8ef719dd8c84d82a3508356b789b00985db3eda9a36766643a3e

Generate multisig script. Denarium coin comes always first and then your second factor key. In my case the second factor public key is
0395c9ebe2467ff6060534c8f831fbc2d0b99e185f93b448b41cf9102429a89345 so I'd run: ./pybtctool mk_multisig_script 049409aa12bd76f6fe8a001d17a8ef719dd8c84d82a3508356b789b00985db3eda9a36766643a3e
bea800c4fa1dc9f26483d46b16776621532f1d21214564bd8b4 0395c9ebe2467ff6060534c8f831fbc2d0b99e185f93b448b41cf9102429a89345 2 2 which returns
5241049409aa12bd76f6fe8a001d17a8ef719dd8c84d82a3508356b789b00985db3eda9a3676664
3a3ebea800c4fa1dc9f26483d46b16776621532f1d21214564bd8b4210395c9ebe2467ff6060534

After that the flow continues as an ordinary multisig spending. Some instructions to continue from here can be found at:
https://bitcoinmagazine.com/articles/pybitcointools-multisig-tutorial-1394686325 starting from
"Now, we can make the transaction..."I hope these instructions are sufficient enough.
Best Regards,
Hopefully someone can support and find me a working solution. I am even willing to pay a small fee if you can offer me a working solution (of course i will have it verified in order to avoid scammers).
Yours sincerely,
Hundionu.
