Rakonto Wordpress Plugin

This is a wordpress plugin that records post and edit timestamps to the litecoin blockchain, providing a verifiable and immutable chain of edits.

This was a side project I helped develop during my time at Edelman Digital in collaboration with the technology director.

I contributed mainly to the transaction explorer.
