We are working on this python file >>micropayment-channel.py(https://github.com/petertodd/checklocktimeverify-demos/blob/master/micropayment-channel.py)
and we got some error

how can we solve these problems

[petertodd]

Oh, checklocktimeverify-demos is really old software; it's probably incompatible with the python-bitcoinlib that you're using. Also, I wouldn't guarantee that it actually works 100% - it's just a demo after all.

The bitcoinlib version we are currently using is the following link.

Is there a newer version of bitcoinlib ??
