[ANN][XCP] Counterparty - Pioneering Peer-to-Peer Finance - Official Thread

[reader31]

For the benefit of others trying to burn xcp, here what I did to get my xcp burnt, my os is ubuntu 13.10,

(These steps worked for me, please feel free to correct/modify/update these instructions as needed)

1)
I downloaded and installed the latest bitcoin-qt client and updated the bitcoin.conf( ~/.bitcoin/bitcoin.conf) with this content,

rpcuser=rpc
rpcpassword=rpcpw1234
server=1
daemon=1
txindex=1

and had the bitcon-qt client running.
 

2)
Next, to get counterpartyd installed, from my home directory I ran this command,

sudo apt-get -y update
sudo apt-get -y install git-core python3.3 python3
git clone https://github.com/xnova/counterpartyd_build ~/counterpartyd_build
sudo python3 ~/counterpartyd_build/setup.py

which completed without any errors.


3)
then I updated the counterpartyd.conf file (~/.config/counterpartyd/counterpartyd.conf) with this content,

[Default]
rpc-connect=localhost
rpc-port=8332
rpc-user=rpc
rpc-password=rpcpw1234

4)
At this point in a new terminal if I run,

counterpartyd --log-file=- -v


If everything from the above steps worked fine, you should see the following output,

2014-01-04-T12:54:47-0800 Starting new HTTP connection (1): localhost
2014-01-04-T12:54:47-0800 "POST / HTTP/1.1" 200 38

2014-01-04-T12:54:51-0800 "POST / HTTP/1.1" 200 38

5)
At this point I was ready to burn. I created a new received address in the bitcoin-qt wallet, deposited 0.01 btc into that address.


In a new terminal, I ran,

counterpartyd --rpc-password=rpcpw1234 burn --from=1CrmTo7Rtk6keeBHbN93B3tAMCm31sG5Tc --quantity=0.01

it asked me for a confirmation(hit 'y').

when the burn is sucessful I immediatley got a confirmation string like this,

"8cc4f74ec9b84fc73c0e092c6243253946431448f675b6d2cfd4398438d3b8df"


You should see your transactions show up on this page,

https://blockchain.info/address/1CounterpartyXXXXXXXXXXXXXXXUWLpVr


after you see your transaction confirmed atleast once, you can go back to your terminal and run,

counterpartyd --rpc-password=rpcpw1234 address 1CrmTo7Rtk6keeBHbN93B3tAMCm31sG5Tc

you should see your balance displayed like this,

Balances
+-------+-------------+

Hope this helps someone!

[wizzardTim]

Thank you very much!!!!

Congrats!!

Now we need a similar guide for windows and later for blockchain.info.

[PhantomPhreak]

Is there any way (command) to gauge progress as counterpartyd is processing the blockchain?

$ ./counterpartyd.py  --rpc-password=$BTCPASS market
Traceback (most recent call last):
  File "./counterpartyd.py", line 407, in <module>
    util.database_check(db)
  File "/home/counterpartycoin/counterpartyd/lib/util.py", line 36, in database_check
    raise exceptions.DatabaseError('Countparty database is behind Bitcoind.')
lib.exceptions.DatabaseError: Countparty database is behind Bitcoind.

Sure. The log file (usually in ~/.config/counterpartyd/counterpartyd.log) shows each block as it's being parsed. When the last block parsed is the last block that Bitcoind has seen (check with bitcoind getinfo), the Counterparty database has caught up with Bitcoind.

[xibeijan]

I got another crash...

[xibeijan]

the bitcoin.conf shouldn't have daemon=1?

Those instructions are for using Bitcoind as the backend for counterpartyd, and then using counterpartyd to burn (entirely safely), not for using Bitcoind to burn BTC directly (which would, at this time, be unsafe).

xnova, when he gets back online soon, should be able to help fix that bug you and a few others are having. I don't think that the daemon=1 option is the problem.

Can I burn more than once from the same BTC address?   For example, burn 0.01 BTC as a test, then burn 0.99 BTC?

What's the min TX fee for bitcoind / counterpartyd?

[xibeijan]

Is there any form of mining with XCP, either in the minting of new CXP (which I doubt) or in the form of harvesting transaction fees?

Thanks.

Yes, you can. counterpartyd will try to warn you if you attempt to burn more than 1 BTC (but if the first burn still isn't confirmed, it might not catch the error!). The fee paid for every Counterparty transaction is 10000 satoshis, as none of them is over a KB.

I seem to have fixed the issue.

xibeijan, how did you get around the 'label empty or too long' error?

[xibeijan]

Yes, you can. counterpartyd will try to warn you if you attempt to burn more than 1 BTC (but if the first burn still isn't confirmed, it might not catch the error!). The fee paid for every Counterparty transaction is 10000 satoshis, as none of them is over a KB.

Do the funds have to all come from the same BTC address?

That is, I have a btw address xfoo...

I TX 0.001 BTX to xfoo...

I counterpartyd burn --from=xfoo.. --quantity=0.0099 [paying the 10,000 satoshi (aka 0.0001 BTC) fee]

So far burned 0.0099

I TX 0.9902 BTX to xfoo...

I counterpartyd burn --from=xfoo.. --quantity=0.9901 [paying the 10,000 satoshi (aka 0.0001 BTC) fee]

So far burned 1.0 BTC

Is this find to do?  Does it all add up correctly?

All good?

Oops...ignore the two different address...you would need to use the same address ofcourse!
Didnt notice i had switched the address. Thx for catching that. Will get that fixed.

Question: what if you forget which bitcoin address you used?   I don't see a command equivalent to listtransactions or getinfo in bitcoind.

Yes, you can. counterpartyd will try to warn you if you attempt to burn more than 1 BTC (but if the first burn still isn't confirmed, it might not catch the error!). The fee paid for every Counterparty transaction is 10000 satoshis, as none of them is over a KB.

I counterpartyd burn --from=xfoo.. --quantity=0.9901 [paying the 10,000 satoshi (aka 0.0001 BTC) fee]

So far burned 1.0 BTC

Is this find to do?  Does it all add up correctly?

All good?

Can anyone confirm the above proceedure is fine?

Also, how many confirmations must I want on BTC transfer?

Thanks.

No, and all of the transaction fees are in BTC, except for those paid in XCP to the operators of 'feeds'.

Does that mean we collect fees in BTC by processing XCP transactions or does it go to the normal bitcoin miners?

Also, what about those pain in XCP to the operators of feeds?  Can you please explain a bit more about who that works or provide a link to the documentation about this.

Highly interesting.
