Question

I tried to connect Multichain using BitcoinJ wallet.  It kept getting timed-out, please help.

Thank you so much

Comments

Are you using the modified BItcoinJ library linked from our website, or the original one? http://www.multichain.com/developers/

---

I'm using the modified Bitconj-Multichain. ( https://github.com/MultiChain/sample-bitcoinj )  I wanted to use it with private assets so I didn't change params.dat to Bitcoin behavior.

---

Hi, from the output above it looks like you're using the latest version of BitcoinJ i.e. bitcoinj:0.14-SNAPSHOT.  You'll need to follow the instructions in the README to build the experimental bitcoinj which has been patched to work with Multichain.  If you are still having issues, please post an update with any error messages and the params.dat file you are using.  Thanks.

Hi, I've followed the instructions in the README.  I'm still having issues.
It didn't report any error but it kept getting connected.

The BitcoinJ sample wallet can only connect to MultiChain when it has been configured to behave like the original Bitcoin blockchain.  The BitcoinJ project itself does not support assets and permissions.
