 The QRL uses [eXtended Merkle Signature Scheme *(XMSS)*](https://eprint.iacr.org/2011/484), a hash based cryptography that's been around since the 70's and recently [approved for use in cryptographic systems by NIST](https://csrc.nist.gov/publications/detail/sp/800-208/final).

+By default an XMSS Tree height of 10 provides 1024 One Time Signatures, or OTS key indexes. You may chose to create a wallet with more or less OTS keys used to sign transactions on the QRL network. 
 
-The only disadvantage for creating a larger tree height is the time required to generate the additional keys. 
 
-This can be configured only when a wallet is created.
+One of the main disadvantages to creating a larger tree height (*amount of OTS Key Indexes*) is the time required to generate the additional keys. Each time you access the wallet the keys must be calculated and thus adding time to opening a larger address. 
 
+These parameters can only be configured when a wallet is created. *The height of the tree is fundamental to the OTS key index creation and adds to the uniqueness of a private key.*

+Correctly recording and securing private recovery keys (*mnemonic or hexphrase*) and then verifying the recovery keys work, is the most important thing a user needs to do before interacting with the QRL network. This ensures that funds are not sent to an address out of your control.
