Abstract
Runic Digits Collective is a consensus standard that allows anyone to claim one of the finite, naturally occurring numbers within the Runes protocol. The supply of the collection is capped by the Runes Protocol character limit. The ownership consensus mechanism outlined herein uniquely allows for trading of either fungible (rune) or non-fungible (inscription) assets. 

Collection Standard
Runic Digits are represented in text format, with each digit spelled out. Padded zeros are NOT recognized, and, as a result, some of the lower Runic Digits will not be etchable for some time.
0 = ZERO
1 = ONE
2 = TWO
3 = THREE
4 = FOUR
5 = FIVE
6 = SIX
7 = SEVEN
8 = EIGHT
9 = NINE
10 = ONE•ZERO
...
9,999 = NINE•NINE•NINE•NINE (The final Runic Digit in the '10k' subcollection)
...
1,000,000 = ONE•ZERO•ZERO•ZERO•ZERO•ZERO•ZERO
...

Ownership Consensus Mechanism
(1) If an inscription was not attached to the Runic Digit when it was etched, then the owner of the Runic Digit is the individual that holds the largest percentage of the Runic Digit's rune.
(2) If an inscription was attached to the rune when it was etched, and the inscription is located in the address '1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa', then the owner of the Runic Digit is the individual that holds the largest percentage of the Runic Digit's rune.
(3) If an inscription was attached to the rune when it was etched, and the inscription is NOT located in the address in (2) above, then the owner of the Runic Digit is the individual that owns the inscription. 

Collection Display Recommendations for Marketplaces
Inscriptions within the collection could have their display names in the format '###.rdc' to make browsing easier. For example, the inscription attached to ONE•ZERO•ZERO•ZERO•ZERO might be displayed as '10,000.rdc'.

Filtering Recommendations for Marketplaces
- Inscription type (Text, image, etc)
- Satributes (Uncommon, Block 9-450x, etc)
- Number of Digits. (Four and under is the Runic Digits '10k' collection)
- Digit patterns. For example: repeat digits, sequential digits, palindromes, etc.
- ...and more!
