At the heart of crypto collectibles (or digital assets) on the blockchain are unique bits & bytes. For CryptoKitties this is a 256-bit integer that holds the super "sekretoooo" genome / genes.

Let's use Kitty #1001 as an example and look at the "magic" 256-bit integer number:

# A 256-bit super "sekretoooo" integer genome

# hexadecimal (base 16)
genome = 0x00004a52931ce4085c14bdce014a0318846a0c808c60294a6314a34a1295b9ce
# decimal (base 10)
genome = 512955438081049600613224346938352058409509756310147795204209859701881294
# binary (base 2)
genome = 0b010010100101001010010011000111001110010000001000010111000001010010111101110011100000000101001010000000110001100010000100\
           011010100000110010000000100011000110000000101001010010100110001100010100101000110100101000010010100101011011100111001110

Let's convert from decimal (base 10) to hexadecimal (base 16 - 2^4) and binary (base 2 that is, 0 and 1):

p genome    # printed as decimal (base 10) by default
#=> 512955438081049600613224346938352058409509756310147795204209859701881294

p genome.to_s(16)
#=> "4a52931ce4085c14bdce014a0318846a0c808c60294a6314a34a1295b9ce"

p genome.to_s(2)
#=> "10010100101001010010011000111001110010000001000010111000001010010111101110011100000000101001010000000110001100010000100\
#     011010100000110010000000100011000110000000101001010010100110001100010100101000110100101000010010100101011011100111001110"

So what? Thanks to Kai Turner who first deciphered the CryptoKitties 256-bit genome in The CryptoKitties Genome Project: On Dominance, Inheritance and Mutation on January 2018 we know today that the genome breaks down into 5-bit chunks. And every 5-bit chunk is a gene. And four 5-bit chunks - known as the primary (p), hidden 1 (h1), hidden 2 (h2), and hidden 3 (h3) gene or dominant (d), 1st recessive (r1), 2nd recessive (r2), and 3rd recessive (r3) - get grouped into a trait (e.g. fur, pattern, eye color, eye shape, base color, highlight color, and so on) resulting in 12 trait groups of 4 (x 5-bit) genes (that is, 12 x 4 x 5-bit = 240 bits) with the remaining leading 16 bits "unused" and zeroed-out (e.g. 0x0000).

Let's break the genome into 5-bit chunks using Base32.encode from the kittyverse gem.

require 'kittyverse'

Base32.format = :electrologica   # use the Electrologica Alphabet / Variant


# hexadecimal (base 16)
genome = 0x00004a52931ce4085c14bdce014a0318846a0c808c60294a6314a34a1295b9ce  # kitty 1001

p Base32.encode( genome )
#=> "09-09-09-09-06-07-07-04-01-01-14-01-09-15-14-14-00-05-05-00-06-06-04-04-13-08-06-08-01-03-03-00-05-05-05-06-06-05-05-03-09-08-09-09-11-14-14-14"

Bingo! Using a genes / traits chart you can now decipher the genome.

CryptoKitties Genes / Traits Chart

Fur (0-3) • Pattern (4-7) • Eye Color (8-11) • Eye Shape (12-15) • Base Color (16-19) • Highlight Color (20-23) • Accent Color (24-27) • Wild (28-31) • Mouth (32-35) • Environment (36-39) • Secret Y Gene (40-43) • Purrstige (44-47)

(Source: kittyverse/GENES.md)

Let's try Kitty #1001 as an example. Let's start deciphering from right-to-left ...06-05-05-03-09-08-09-09-11-14-14-14, that is, 14 maps to ragamuffin, 14 to ragamuffin, 14 to ragamuffin, 11 to himalayan, and so on:

Fur (FU) - Genes 0-3:

5-Bit Chunk	Gene	Trait
14	0	ragamuffin	Primary
14	1	ragamuffin	Hidden 1
14	2	ragamuffin	Hidden 2
11	3	himalayan	Hidden 3

Pattern (PA) - Genes 4-7:

5-Bit Chunk	Gene	Trait
09	4	luckystripe	Primary
09	5	luckystripe	Hidden 1
08	6	calicool	Hidden 2
09	7	luckystripe	Hidden 3

Eye Color (EC) - Genes 8-11:

5-Bit Chunk	Gene	Trait
03	8	mintgreen	Primary
05	9	sizzurp	Hidden 1
05	10	sizzurp	Hidden 2
06	11	chestnut	Hidden 3

and so on.

Let's try another kitty #1111:

genome = 0x000042d28390864842e7b9c900c6321086438c6098ca298c728867425cf6b1ac # kitty 1111

p Base32.encode( genome )
#=> "08-11-09-08-07-04-04-06-09-01-01-14-15-14-14-09-00-03-03-03-04-04-04-06-08-14-06-06-01-06-06-10-05-06-06-07-05-02-03-07-08-09-14-15-13-12-13-12"

Again using a genes / traits chart you can now decipher the genome. Let's start from right-to-left ...05-02-03-07-08-09-14-15-13-12-13-12, that is, 12 maps to munchkin, 13 to sphynx, and so on:

Fur (FU) - Genes 0-3:

5-Bit Chunk	Gene	Trait
12	0	munchkin	Primary
13	1	sphynx	Hidden 1
12	2	munchkin	Hidden 2
13	3	sphynx	Hidden 3

Pattern (PA) - Genes 4-7:

5-Bit Chunk	Gene	Trait
15	4	totesbasic	Primary
14	5	totesbasic	Hidden 1
09	6	luckystripe	Hidden 2
08	7	calicool	Hidden 3

Eye Color (EC) - Genes 8-11:

5-Bit Chunk	Gene	Trait
07	8	strawberry	Primary
03	9	mintgreen	Hidden 1
02	10	topaz	Hidden 2
05	11	isotope	Hidden 3

and so on.

What's Base32?

Encoding / decoding numbers in 5-bit chunks is called base 32 because 2^5 (=2 * 2 * 2 * 2 * 2) results in 32 values. Using the Electrologica notation / alphabet (00 01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31) the conversion chart reads:

Base32	Binary	Num	Base32	Binary	Num	Base32	Binary	Num	Base32	Binary	Num
00	00000	0	08	01000	8	16	10000	16	24	11000	24
01	00001	1	09	01001	9	17	10001	17	25	11001	25
02	00010	2	10	01010	10	18	10010	18	26	11010	26
03	00011	3	11	01011	11	19	10011	19	27	11011	27
04	00100	4	12	01100	12	20	10100	20	28	11100	28
05	00101	5	13	01101	13	21	10101	21	29	11101	29
06	00110	6	14	01110	14	22	10110	22	30	11110	30
07	00111	7	15	01111	15	23	10111	23	31	11111	31

What About Kai Notation / Alphabet?

The Kai (Base 32) notation / alphabet is named in honor of Kai Turner who first deciphered the CryptoKitties 256-bit genome in 5-bit chunks. The Kai notation / alphabet follows base56 and uses (123456789abcdefghijkmnopqrstuvwx). The conversion chart reads:

Kai	Binary	Num	Kai	Binary	Num	Kai	Binary	Num	Kai	Binary	Num
1	00000	0	9	01000	8	h	10000	16	q	11000	24
2	00001	1	a	01001	9	i	10001	17	r	11001	25
3	00010	2	b	01010	10	j	10010	18	s	11010	26
4	00011	3	c	01011	11	k	10011	19	t	11011	27
5	00100	4	d	01100	12	m	10100	20	u	11100	28
6	00101	5	e	01101	13	n	10101	21	v	11101	29
7	00110	6	f	01110	14	o	10110	22	w	11110	30
8	00111	7	g	01111	15	p	10111	23	x	11111	31

Note: - the digit-0 and the letter-l are NOT used in the kai alphabet / notation.

Let's convert the example kitty genomes to Kai notation:

require 'kittyverse'

Base32.format = :kai   # use the Kai Alphabet / Variant


# hexadecimal (base 16)
genome = 0x00004a52931ce4085c14bdce014a0318846a0c808c60294a6314a34a1295b9ce  # kitty 1001

p Base32.encode( genome )
#=> "aaaa788522f2agff16617755e979244166677664a9aacfff"

genome = 0x000042d28390864842e7b9c900c6321086438c6098ca298c728867425cf6b1ac # kitty 1111

p Base32.encode( genome )
#=> "9ca98557a22fgffa144455579f77277b677863489afgeded"

Tip: Use the Base32.fmt helper to pretty print / format the encoded string into a group of four (genes). Example:

# hexadecimal (base 16)
genome = 0x00004a52931ce4085c14bdce014a0318846a0c808c60294a6314a34a1295b9ce  # kitty 1001

p Base32.fmt( Base32.encode( genome ))
#=> "aaaa 7885 22f2 agff 1661 7755 e979 2441 6667 7664 a9aa cfff"

genome = 0x000042d28390864842e7b9c900c6321086438c6098ca298c728867425cf6b1ac # kitty 1111

p Base32.fmt( Base32.encode( genome ))
#=> "9ca9 8557 a22f gffa 1444 5557 9f77 277b 6778 6348 9afg eded"
p Base32.fmt( genome )   # or use the "all-in-one" shortcut
#=> "9ca9 8557 a22f gffa 1444 5557 9f77 277b 6778 6348 9afg eded"

Build Your Own CryptoKitties Gene Reader

Let's code a gene reader that deciphers the genome. Let's automate the lookup of the 5-bit chunks mapping to traits.

Let's again (re)use the kittyverse gem that includes an up-to-date list of all traits. For example, try:

require 'kittyverse'

pp TRAITS     ## pretty print (pp) TRAITS, that is, list of all traits

Resulting in:

That's quite a list that you do not have to type in. Let's use the new TRAITS hash to "automagically" decipher the genome.

# hexadecimal (base 16)
genome = 0x00004a52931ce4085c14bdce014a0318846a0c808c60294a6314a34a1295b9ce  # kitty 1001

genes_kai = Base32.encode( genome )
p genes_kai
#=> "aaaa788522f2agff16617755e979244166677664a9aacfff"
genes_kai = genes_kai.reverse    # for easy array access reverse string
p genes_kai
#=> "fffcaa9a466776661442979e55771661ffga2f225887aaaa"

Note: Every trait has four genes (primary, hidden 1, hidden 2, and hidden 3). The primary gene is the "cattribute", that is, the visible trait listed on the official kitty profile page. Let's (double) check for the Kitty #1001:

Fur: ragamuffin
Pattern: luckystripe
Eye Color: mintgreen
Eye Shape: crazy
Base Color: shadowgrey
Highlight Color: swampgreen
Accent Color: granitegrey
Mouth: happygokitty

And the official page:

(Source: cryptokitties.co/kitty/1001)

Bingo! The cattributes match up.

For easy (re)use lets put together a more "generic" print_genes method:

print_genes( 0x00004a52931ce4085c14bdce014a0318846a0c808c60294a6314a34a1295b9ce ) # kitty 1001
print_genes( 0x000042d28390864842e7b9c900c6321086438c6098ca298c728867425cf6b1ac ) # kitty 1111

And the code:

def print_genes( genome )

  genes_kai = Base32.encode( genome )
  genes_kai = genes_kai.reverse    # for easy array access reverse string

  TRAITS.each_with_index do |(trait_key, trait_hash),i|

     # note: skip wild, environment, secret, prestige for now
     next if [:wild,   :environment,
              :secret, :prestige].include? trait_key

     offset = i*4
     puts "#{trait_hash[:name]} (#{trait_hash[:code]}) - Genes #{trait_hash[:genes]}:"
     puts "#{'%2d' % (0+offset)} | #{trait_hash[:kai][genes_kai[0+offset]]}"
     puts "#{'%2d' % (1+offset)} | #{trait_hash[:kai][genes_kai[1+offset]]}"
     puts "#{'%2d' % (2+offset)} | #{trait_hash[:kai][genes_kai[2+offset]]}"
     puts "#{'%2d' % (3+offset)} | #{trait_hash[:kai][genes_kai[3+offset]]}"
     puts
  end
end

See a difference? There's no difference :-).

Note: The kittyverse gem has a built-in gene reader and pretty printer. Let's try it:

genome = Genome.new( 0x00004a52931ce4085c14bdce014a0318846a0c808c60294a6314a34a1295b9ce )
puts genome.build_tables    # outputs tables in text with markdown formatting
