Balances in Nano are stored in a 128-bit integer value.  There are various
units for representing the balance, the smallest and base unit is called
.RI \(dq raw \(dq.
The most common unit for users to use is called
.RI \(dq Nano \(dq,
one of which is equal to 1e30 raw.

.SS Addresses
Nano addresses are composed of a prefix (either
.RB \(dq nano_ \(dq
or
.RB \(dq xrb_ \(dq)
and 300 bits of base32 encoded data.  The 300-bits of base32 encoded data
produce a string that is 6 charectars long using the base32 alphabet
.BR 13456789abcdefghijkmnopqrstuwxyz .
The format of these 300 bits are
.EX

  [Padding (4 bits: 0)].[Public Key (256 bits)].[Checksum (40 bits)]

.EE
For example the public key
.B DC1512154EB72112B8CC230D7B8C7DD467DA78E4763182D6CAFAADB14855A5E8
would be encoded as
.B 0000.DC1512154EB72112B8CC230D7B8C7DD467DA78E4763182D6CAFAADB14855A5E8.9C46A37418
which when encoded in base32 and the prefix added produces the address
.BR nano_3q1o4acnxfs34cwerarfhg89uo59ubwgaxjjiddeoyofp767dbhamj5c8x1r .
The checksum is computed as a 5 byte (40 bit) Blake2b hash of the 256-bit
public key (in binary format), followed by reversing the bytes.
