It's come to my attention that this post is being misused by @dineroconopcion to justify asking for people's private posting key.
I encourage all users to treat their accounts' permissions and keys with care. This goes for any third party you may provide your posting key to. If their key list is compromised:
- your posts may be edited, defaced, or replaced with spam
- someone could post or comment with spam, scams, or resteem anything
- your vote power may be drained voting on things you don't want to vote on
- your account may follow people you don't want to follow
Though it limits potential economic damage to your account, the private posting key is still a key that should be kept private.
thank for the advice @pfunk a have seen a lot of third parties asking for the private posting key
So is STEEM different in its block chain implementation as compared to bitcoin? In the sense that I thought once something is on the blockchain it cannot be changed. My question being how is it possible to edit previous posts once they are already a part of the blockchain?
It's true once data is into a blockchain, it's near impossible to change it. Edits are done in Steem by adding new posts or comments to the blockchain that use the same permalink title as the previous post. The edits contain the changes and some special characters that tell the Steem front end how the post is edited by the new edit transaction.
I edited this comment after posting the above paragraph to illustrate. I will edit it again to show you what the edit transaction looks like.
Okay i understand now
