Title: BlockExplorer.com transaction history changes Post by: bitplane on January 22, 2012, 08:25:35 PM I set up a daily ChangeDetection.com alert on one of my addresses changing, as per Casascius's smart idea of using Bitcoin as a hacker canary (https://bitcointalk.org/index.php?topic=60219.0), and got a couple of email alerts which are worrying:
http://www.changedetection.com/log/blockexplorer/1gyzhwalymnvkgrkszcabruuhcxvtwpawf_log.html As you can see, the balance didn't change but the transaction history did, there's no mention of a bug on BlockExplorer's home page. Was BlockExplorer's transaction history wrong for a day? Is it right now? Does this happen often? Can we trust it‽ Title: Re: BlockExplorer.com transaction history changes Post by: Maged on January 22, 2012, 08:35:30 PM Doesn't look like either history is actually wrong. The only changes were in the order in which the inputs of a transaction were consumed.

The only changes were in the order in which the inputs of a transaction were consumed. Right. Both versions were correct. BBE was ordering those sends "randomly". I changed it to use a consistent ordering.

Excellent, thanks for the explanation :) Title: Re: BlockExplorer.com transaction history changes Post by: cypherdoc on January 23, 2012, 01:35:04 AM i set up the same ChangeDetection acct from that same thread a few days ago and i've had alert notifications every day since even tho my balance hasn't changed and i haven't touched the address in over a month. i can't see any obvious changes.

You should use this page instead: http://blockexplorer.com/q/getsentbyaddress It's much less likely to change randomly. |
