Thu, 04 Apr 2019 14:48:37 +0000

I'm on Ubuntu 16.04 (Docker image), with the following Dockerfile:

But I get the error "hexdump is required for tests". It happens when running the ./configure.sh script

Hello,

This is Seo. I got some errors while building the multichain 2.0 source from 2.0-dev as follows:

on new installed Ubuntu 18.10, I followed readme.md and v8.md

I have encrypted a running node's wallet - node stop syncing

Wed, 17 Oct 2018 13:30:32 +0000

Hi,

I have encrypted a running node's wallet (encryptwallet) and now the node is stop syncing with the network.

The debug messages are:

2018-10-17 13:23:59 mchn: Sending minimal parameter set to xx.xx.xx.xx:yyyy

It is stop working at that block height (when I encrypted the wallet), the network height now is 85076

How to fix a broken chain?

Sun, 30 Sep 2018 05:16:01 +0000

I've been playing around with MultiChain Web Demo and got 'Error: HTTP 200' when I uploaded a file within the Issue Assets section. I took a look at it in the multichain-cli with the 'listwallettransaction' command and it looks like the @file value contains a open double quote (") which improperly quits the JSON.

Is there a way to fix this? Did I break the chain? Could someone shed light on why this happening even though I'm still able to issue assets within the CLI.

How do I fix an invalid JSON error?

Wed, 11 Apr 2018 08:37:08 +0000

I am trying to run python -m Mce.abe --config chain1.conf --commit-bytes 100000 --no-serve to run the explorer.

But Im getting an error regarding an invalid /escape character. I bypassed that issue by replacing the " with a '.

But now Im getting an invalid JSON error. IS this related or am I running into a new issue.

Im running on Windows and Im also restricted to windows.

Is there a fix for Compiles Error on Mac?

Prev Out already spent

Tue, 03 Jan 2017 19:18:56 +0000

How can I get the Bitcoin out of my wallet now?

Every time I try to spend money I get the same error. Any money I add to that account is now frozen too. My wallet works fine with my other accounts but my main account with considerable money in it seems to be lost. I've tried spending different amounts, sending to different addresses and just transferring the money internally within my wallet. Nothing works.

Prev out already spent DBOutput (Outpoint=outpointmpl (txindex=205168040, txoutput N=1) , spending_outpoints=OutpointsImpl(txindex=2051688618,txOutputN=7)

Is there a solution to this problem? Or is the money lost?
