Asset transfer in case of a disconection

Tue, 21 Jan 2020 17:27:44 +0000

Hi MC Team

This is the scenario

I have a QR reader ( this reader is conected directly via ethernet to a small piece of harware running multichain node )and this executes the api call sendasset from ( the multichain address enconded in the QR) and it turns out this have a 1 usd balance in an asset called "dollar". Everything is ok meanwhile the reader is online and sycn with the node. What happen if a payment is attemped during a network interruption of a couple of minutes and the local node cannot synchronize with the primary node? How can I guarantee that the local node has the whole bunch of records before the network interruption and this "payment" can be executed?

I know this a little tricky but it is very important.

Thanks in advance.

Using pybitcoin tools to sign transactions offline

I'm having trouble using pybitcoin tools to sign transactions offline : https://github.com/vbuterin/pybitcointools

I'm using multichain-cli to create the raw transaction:

1) createrawtransaction '[{"txid":"f098143b389bf7ff19c26d8d051ac4351f255cdb1f41735cf4fa723b9e38893","vout":0}]' '{}'

Output: 01000000019388e3b923a74fcf3517f4b1cd54251f35c41a058d6dc219fff79b383b1498f00000000000ffffffff0000000000

2) appendrawdata 01000000019388e3b923a74fcf3517f4b1cd54251f35c41a058d6dc219fff79b383b1498f00000000000ffffffff0000000000 5554584f732046545721

Output: 01000000019388e3b923a74fcf3517f4b1cd54251f35c41a058d6dc219fff79b383b1498f00000000000ffffffff0100000000000000000c6a0a5554584f73204654572100000000

3) And then using pybitcoin tools...

tx = \
'01000000019388e3b923a74fcf3517f4b1cd54251f35c41a058d6dc219fff79b383b1498f00000000000ffffffff0100000000000000000c6a0a5554584f73204654572100000000'

signed_tx = sign(tx, 0, 'c19baef3f8c7cd8df7aab108ef8578dd6694fed976c85cd8213cdaec3d7e4ebd')

4) When calling sendrawtransaction using the hex result from signing in step 3, I get the following error.

error code: -26
error message:
16: ConnectInputs failed

Any advice??
