 A few notes on the `Keyring` methods:
 
-- `Sign(uid string, msg []byte) ([]byte, tmcrypto.PubKey, error)` strictly deals with the signature of the `message` bytes. Some preliminary work should be done beforehand to prepare and encode the `message` into a canonical `[]byte` form, and this is done in the `GetSignBytes` method. See an example of `message` preparation from the `x/bank` module. Note that signature verification is not implemented in the SDK by default. It is deferred to the [`anteHandler`](#antehandler).

 In both case, the actual key (as raw bytes) is the compressed form of the pubkey. The first byte is a `0x02` byte if the `y`-coordinate is the lexicographically largest of the two associated with the `x`-coordinate. Otherwise the first byte is a `0x03`. This prefix is followed with the `x`-coordinate.
 
 Note that in the Cosmos SDK, `Pubkeys` are not manipulated in their raw bytes form. Instead, they are encoded to string using [`Amino`](../core/encoding.md#amino) and [`bech32`](https://en.bitcoin.it/wiki/Bech32). In the SDK, it is done by first calling the `Bytes()` method on the raw `Pubkey` (which applies amino encoding), and then the `ConvertAndEncode` method of `bech32`.
