Hello.
At the official explorer (
http://wavesexplorer.com/), searching by address without '1W' prefix won't work.
Some waves addresses have '1W' prefix, and some don't. Which is correct?

Hey! Both addresses are correct. '1W' prefix was used in the previous versions of the software. Later,
http://wavesexplorer.com will be updated (the new site will be available via this link:
http://www.wavesgo.com/)
