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>`. 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
<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).

### Examples
1. For example, the 33-byte (or 0x21-byte in hex) Secp256k1 pubkey
`020BD40F225A57ED383B440CF073BC5539D0341F5767D2BF2D78406D00475A2EE9`
`020BD40F225A57ED383B440CF073BC5539D0341F5767D2BF2D78406D00475A2EE9`
would be encoded as
`EB5AE98221020BD40F225A57ED383B440CF073BC5539D0341F5767D2BF2D78406D00475A2EE9`

### Addresses
Addresses for each public key types are computed as follows:
#### Ed25519
RIPEMD160 hash of the Amino encoded public key:
```
address = RIPEMD160(AMINO(pubkey))
```
NOTE: this will soon change to the truncated 20-bytes of the SHA256 of the raw
public key
#### Secp256k1
RIPEMD160 hash of the SHA256 hash of the OpenSSL compressed public key:
```
address = RIPEMD160(SHA256(pubkey))
```
This is the same as Bitcoin.
