 Usage
 
-`mroot(leaves, hasher, bitcoin = false)`
+`mroot(leaves, hasher, compat = false)`
 
-`leaves` your array or set of **pre-hashed** messages
+`leaves` your ordered array or set of **pre-hashed** messages
 
 `hasher` your pair-hashing function, e.g. `(a, b) => sha256(a + b)`
 
-`bitcoin` whether to pad each layer to an even number of nodes by duplicating
-the last leaf, if necessary, for compatibility with Satoshi's Merkle tree

 implementation in Bitcoin
 
-SECURITY NOTES
+**Notes on Merkle tree security**
 
-1. Each leaf must be externally validated, to protect against the second
-preimage attack.
 
-  For example, given leaves `A = "alice"` and `B = "bob"`, the
-root of `[A, B]` is the same as the root of just `[C]`, where  `C =
-hash("alice") + hash("bob")`.

+    preimage attack.
 
-  YOU SHOULD BE OK if you reject `C` (e.g. because it's actually a binary hash
-blob and you were expecting a name) and you don't permanently flag the root
-itself as invalid (preventing you from accepting the legitimate `[A, B]`).

-2. Do not use the root as an HMAC if your hasher is vulnerable to
-length-extension.

-  For example, for your shared secret key `K` and message `M`, the naive signature
-`sha256(K + M)` can be used by anyone to make `sha256(K + M + X)` to make it seem like you signed `X` as well.

-strictly-formatted messages.

-3. Do not use the Bitcoin compatibility option unless you handle the fact that
-you will get the same root with a potentially invalid, duplicated last-pair of
-leaves.

-  For example, the leaves `[A, B, C]` will have the same root as the leaves
-`[A, B, C, C]`. If you earmark the root itself as invalid because you don't like
-`C` being duplicated, then you might accidentally reject `[A, B, C]` as well.
