<comments removed> Please do not use comments to answer these questions. This proposal is not part of a Q&A site, and the task at hand is to help define what is on and off topic for a site. Comments are here to help improve the questions; not to answer them. See What is the rationale for deleting answers? Thank you. – Robert Cartaino Aug 10 '15 at 13:53
Ah, sorry... Did not realise that. Thanks for the clarification... – Srlle Aug 11 '15 at 12:58

How to create a multisignature address on ethereum?
added by Pascal Van Hecke Aug 3 '15 at 22:07

The pedant in me would like to have this question corrected to "How can you create" instead of "How to create". – eMansipater Aug 8 '15 at 16:08

The pedant in my English master would correct this to, "How can one create" instead of "How can you create". Luckily pedants are rare on SX or we'd spend all of our time in grammatical flame wars :-) – pinoyyid Aug 9 '15 at 11:25

I want to write a contract that relies on hidden information, but Ethereum transactions are public. Any workarounds?
added by PeterBB Aug 4 '15 at 2:52

Phrasing is too casual. Rephrase to: "How can we write a contract that relies on hidden information? Ethereum transactions are all public." – user75798 Aug 8 '15 at 23:36
Simpler edit since it's already pretty clear--just change the question part to "Are there any common workarounds I can use in this type of situation?" – eMansipater Aug 10 '15 at 17:46
