RE: Using the STEEM blockchain for forensic data integrity

in #dfrws6 years ago

How can I track content prior to edition of a post?
Searched for a relevant place to ask about it.
steemd.com and steemblockexplorer.com seem to have failed me at it.

It's a bit fiddly.

  1. Get the "created" and "last_updated" fields from the post.
  2. Do a binary search to find the blocks matching these timestamps.
  3. Fetch every block in the range between the two identified blocks and look for updates with matching permalink and author.

Hope this helps.

Does it mean that it got cryptic and obscure enough that it is no longer accessible through the blockchain explorers (the platform itself never had the ability to find versions of the content prior to the last)?

  1. Do a binary search to find the locks matching these timestamps.

You meant blocks instead of locks?
It took me more than one read in order to guess.

Yes, blocks, not locks, sorry. As far as I know the only way to get at all the the older versions is this fiddly way. But then I only use the condenser API, maybe one of the other API's has ways to do it more directly.
