Intro

DeepOnion recently published their new wallet which supports the long awaited stealth addresses. After they released their new wallet many users reported from syncing issues with the newest Version v1.6.0. Due to a necessary hard fork the new nodes caused a chain split although the consensus changes should not be activated before block 460 000 (approximate on 02.04.2018).

Everyone who doesn't know what a hard fork or a chainsplit is should read this article.

Summarized a chain-split is mostly unintended and unwanted and can cause some serious issues. This was the first incident I witnessed and I was curious about how DeepOnion will handle it. Spoiler Alert: prompt and professional.

They managed to fix all issues in under 24 hours and inform they majority of their user base about it. I want to share my observations and a historical summary with you.

Conclusion

I wrote this article because I was impressed how supportive the DeepOnion community is. After the issues started many users and team members helped each other out and the developers started instantly with the troubleshooting. Constant updates helped the members to keep calm.

This is how an active community looks like! DeepOnion is doing a great job.
