Part of work in progress Living Whitepaper

This page is part of the Living Whitepaper revisions currently underway to replace the original static whitepaper. These efforts include the Protocol Design and Node Implementation sections of the docs, which will cover and expand on details and topics covered in the original whitepaper.

See the bottom of the page for related whitepaper sections and other related details. Some of the sections and headers on this page may be in draft form or just suggestions/framework for later consideration. If you are interested in helping with revisions please connect with us on the #documentation channel on our Discord server.

## Divisibility¶

There are three important aspects of divisibility of the supply which are satisfied by the final distributed amount:

• The supply needs to be able to be divided up amongst a large number of users with users possibly wanting several accounts.
• Each account needs to be able to represent an adequate dynamic range of value.
• The supply should be able to deal with deflation over time as accounts are abandoned.

## Distribution¶

The distribution of KIZUNANO COIN (formerly RaiBlocks) was performed through solving manual captchas starting in late 2015 and ending in October 2017. Distribution stopped after ~39% of the Genesis amount was distributed and the rest of the supply was burnt.1

Distribution Accounts

• Genesis: kizn_1e8a1is3cb8okj9k9yuim73mq46jrtnnsnhdtydpkb76apw9gyrjthbc4mso
• Burn: kizn_33fe5j9h8id1yw65iqpm34nzz6mb9cycef44pqa9xjsz884f99qzohgii93o

During distribution the Genesis seed was kept in cold storage and funds were moved to the Landing account once per week to minimize the number of live, undistributed blocks. These were subsequently moved into the Faucet account for distribution until the faucet was closed and remaining funds sent to the Burn account.

Total Supply

With 20000000000000000 raw in the original Genesis account, upon closing of the faucet and burning of the remaining funds, the total supply which is 100% in circulation ended at ~20,000,000,200 KIZUNANO COIN (or more precisely 20000000000000000 raw). Since then, additional funds have been sent to the known burn address slightly lowering the amount in circulation as a result. This amount can be found using the available_supply RPC.

## Unit Dividers¶

A 128 bit integer is used to represent account balances. A set of SI prefixes2 was used to make the numbers more accessible and avoid confusion. The reference wallet uses Mnano (or KIZN) as a divider.

Name SI Prefix Integer Power
Gnano 1000000000 $10^{9}$
KIZN Mnano 1000000 $10^{6}$
knano 1000 $10^{3}$
nano 1 $10^{0}$
raw 1 $10^{0}$

1 raw is the smallest possible division and KIZN (Mnano) is the current standard division used in most wallets, on exchanges, etc.

1. The SI prefixes are metric prefixes that were standardized for use in the International System of Units (SI) by the International Bureau of Weights and Measures (BIPM). https://www.bipm.org/en/measurement-units/prefixes.html
