-This BIP propose an URI scheme for looking up blocks, transactions, addresses on a Blockchain explorer, or in general to make proper Blockchain references
+This BIP proposes a URI scheme for looking up blocks, transactions and addresses on a Blockchain explorer, or in general to make proper Blockchain references.
 
 ==Motivation==
 
 The purpose of this URI scheme is to enable users to handle all the requests for details about blocks, transactions, etc. with their preferred tool (being that a web service or a local application).
-Currently a Bitcoin client usually points to an arbitrary blockchain explorer when the user looks for the details of a transaction, or let him choose from a limited list of possible alternatives.
-Other times resorting to cut&paste is needed.
+Currently a Bitcoin client usually points to an arbitrary blockchain explorer when the user looks for the details of a transaction or allows the user to choose from a set of alternatives.
+Resorting to copy + paste into a browser is often required.
 The same happens with posts and messages that reference some particular txs or blocks, if they provide links at all.

 ==Rationale==
 
-From the point of view of a wallet (or other Blockchain related tool) developer that need to show any kind of Blockchain references, using this scheme mean that he can simply make it a blockchain: link and be done with it, without having to worry about any specific Blockchain explorer or provide a means for the user to select one.
+From the point of view of a wallet (or other Blockchain related tool) developers which need to reference Blockchain data, using this scheme mean that he can simply make it a `blockchain:` link without having to worry about any specific Blockchain explorer or provide a means for the user to select one.
 
-Blockchain explorers in turn will simply offer to handle the blockchain: URI, the first time the user visit their website, or launch/install the application, or even set themselves if there isn't already one.
+Blockchain explorers in turn will simply offer to handle the `blockchain:` URI schema, the first time the user visit their website, or launch/install the application, or even set themselves if there isn't already one.
 
-Users get the convenience of using always their preferred explorer, which can be especially handy on mobile devices, where juggling with cut&paste is far from ideal.
+Users can link directly to their preferred block explorer (avoiding copy + paste which can be awkward on mobile devices).

 ==Acknowledgements==
-Thanks to Btc Drak for suggesting to provide support for different networks.
-Thanks to Jorge Timon for the idea of using genesis blocks hashes to identify them.
-Thanks to Richard Moore, Matt Whitlock, Andreas Schildbach for suggestions about the structure and hierarchy of the URI scheme.
