In what follows, we provide the type names and prefix bytes directly.
Notice that when encoding byte-arrays, the length of the byte-array is appended
to the PrefixBytes. Thus the encoding of a byte array becomes `<PrefixBytes>
<Length> <ByteArray>`
<Length> <ByteArray>`. In other words, to encode any type listed below you do not need to be
familiar with amino encoding.
You can simply use below table and concatenate Prefix || Length (of raw bytes) || raw bytes
( while || stands for byte concatenation here).

`020BD40F225A57ED383B440CF073BC5539D0341F5767D2BF2D78406D00475A2EE9` would be
