Token model


OKP4 Token Model aims to:

  • secure the network by providing sufficient incentives for validators to participate and delegators to stake their tokens;
  • ensure low-cost participation for Providers and Consumers;
  • incentivize long-term token holding;
  • secure open-source funding & network maintenance.

One issue we've seen with many other Cosmos-based chains is that to secure the network, they define an inflation parameter (usually ranging from 10% to 30%), resulting in token selling pressure and unattractive price action.

One way to secure the network while limiting inflation is by providing rewards derived from network activity. Unlike Ethereum's EIP-1559, which reduces inflation through fee burning, OKP4 introduces a tax on specific network activity: the workflows. As with VAT (value-added tax), a fraction of the workflow's price can be collected to secure the network while reducing selling pressure and even resulting in long-term $KNOW supply reduction.

In OKP4, the two main parameters influencing the inflation rate are (1) the bonding ratio and (2) the workflow tax.

Bonding ratio

The bonding ratio is the ratio between the number of tokens staked and the number of existing tokens. The higher the bonding ratio, the more tokens are needed to increase a validator's voting power. The staking rewards increase when the bonding ratio decreases to ensure the bonding ratio stays high. This would further incentivize token holders to stake their tokens.

Workflow tax

OKP4 aims to reduce $KNOW inflation while maintaining a security budget to incentivize validators and delegators. Inflation can be considered as value extracted from existing token holders; another source of value needs to be found.

The primary chosen source of revenue is workflows. Workflows are initiated and paid by Consumers to retribute Providers.

Tomorrow, thousands of applications will be leveraging OKP4, each generating many workflows. For each workflow, Consumers pay Data providers and Service providers according to the business model defined on-chain. A tax is applied to the workflow's price. The tax percentage is a parameter defined through DAO governance. This tax is collected into a tax pool and redistributed to validators and delegators.

This tax pool compensates for inflation. The higher the tax collected on workflows, the lower the inflation rate. If the daily tax pool exceeds the Staking Reward Target (SRT), then the SRT is distributed from the tax pool, no new tokens are minted, and the remaining tokens are burnt, reducing the token supply. Another effect of that tax is to prevent fake volume on datasets and services, making volume a more robust reputation metric.

Staking reward target

The Staking Reward Target (SRT) is defined for an epoch on a daily basis.

Let's define the daily staking reward target, denoted as srtdsrt_d:

srtd=ai(cbbt)srt_d = a \cdot i \cdot \left(c - \frac{b}{b_t}\right)


  • srtdsrt_d represents the daily staking reward target.
  • aa is a variable representing the $KNOW supply at the end of the epoch (200,000,000 at genesis).
  • i=0.02%i = 0.02\% is the daily inflation coefficient.
  • c=2.5c = 2.5 is the bonding ratio adjustment coefficient.
  • b[0,1]b \in [0,1] is a variable representing the bonding ratio at the end of the epoch.
  • bt=66%b_t = 66\% is the target bonding ratio.

This formula yields the following daily SRT, without considering the dynamic nature of the $KNOW supply, which may increase or decrease.

Plot of srtd = a . i . (c - b / bt)

The daily SRT, srtdsrt_d, is linearly influenced by the bonding ratio and is capped to a maximum and minimum, adjusted according to the token supply.

Now, let's express the yearly staking reward target as a percentage of the supply, denoted as srty%srt_y^\%. This would correspond to the yearly inflation if no tax were collected. It is defined as follows:

srty%=365srtda=365i(cbbt)srt_y^\% = \frac{365 \cdot srt_d}{a} = 365 \cdot i \cdot \left(c - \frac{b}{b_t}\right)

As a yearly percentage of the token supply, this yields the following chart:

Plot of srty = 365 . i . (c - b / bt)

Adjusting reduction

At the end of each epoch, the tax pool, denoted as poolpool, is collected and distributed among validators and delegators. This process impacts the inflation rate for the subsequent epoch.

The quantity of $KNOW tokens, represented as VV, to be minted during the epoch is adjusted at the onset of each epoch based on the value of Δ\Delta, where:

Δ=srtdpool\Delta = srt_d - pool

1. If the daily tax pool falls short of the daily staking reward target (i.e., Δ>0\Delta > 0), the adjustment is as follows:


In this case, the shortfall Δ\Delta is made up by minting additional $KNOW tokens.

2. If the tax pool is equal to or exceeds the staking reward target (i.e., Δ0\Delta \leq 0), the adjustment is as follows:

Δ is burnt\lvert \Delta \rvert \text{ is burnt}

In this case, no new $KNOW tokens are minted, and the excess amount Δ\lvert \Delta \rvert is removed from the circulating supply, effectively burnt. This mechanism helps to control inflation by reducing the total supply of tokens when the tax pool is sufficient or exceeds the staking reward target.

Other payment tokens

In the future, Consumers will be able to pay for workflows using other payment tokens, such as stablecoins. The Providers will be paid with that payment token, and the tax will still apply. These payment tokens will need to be approved by governance, and a default route and timing mechanism to be swapped into $KNOW will be defined. At the end of the epoch, the tax pool will be composed of $KNOW tokens, even if other tokens are used for payment.

Other taxes on workflows

Beyond inflation reduction and burning, additional workflow taxes are set to be distributed for specific purposes. One key purpose is public goods funding and providing incentives for builders. These taxes can be given to the community pool and strategic treasury. As with the tax pool for validators and delegators, the DAO governance decides the tax levels at the protocol's level.
