Reputation tokenomics
Here we analyze the tokenomics derived from the REP Token Minting Mechanism. That means we detail models for REP token evolution under a variety of assumptions, such as when the DAO enjoys constant or exponentially changing rates of incoming fees. We derive the income stream of a REP token, and calculate its present value.
The results give us more precise intuition for how to manipulate the parameters to drive the system in different ways. For instance, a DAO may choose to change the number of tokens minted when fees enter the system (denoted by ). The analysis shows how inflationary minting of REP encourages decentralization, and to what degree parameter choices strengthen or weaken the effect. Such calculations precisely account for how different types of members (especially older or newer members) benefit from different DAO governance decisions, which clarifies the true moral principles the DAO embodies. This allows us to compare the functioning of a DAO against its marketing, in order to objectively evaluate the group’s values and integrity.
REP Valuation
Basic parameters
REP valuation models are based on the following parameters:
- the total number of REP tokens in the DAO at time .
- The rate of total fees that the DAO earns. Therefore denotes the total fees earned from the beginning of the DAO until time .
- cumulative reputational salary collected for one token from start time when the token was minted until time . This is our function of primary concern. After determining its formula, we are most interested in its present value .
- minting ratio. I.e., the proportion of REP tokens that are minted relative to the fees the DAO collects. The default assumption is .
- The base interest rate or the inflation rate of the stable coin in which the fees are paid. Either notion may be denoted with the symbol . The default assumption is .
- ??Probably going to drop this or add a comment somewhere.??The proportion of the fees that is given to the DAO to fund the reputational salary. The default assumption is that 100% is given to the DAO, i.e., that . The reasons why might not be 0 follow two general causes, but the calculations and results are equivalent.
- A proportion of the fees may be given directly to the worker who earned the fees. People often expect an immediate reward from work, so we give the calculations, but making it is a security threat to the architecture. The more secure approach is the standard architecture, which assumes only newly minted REP tokens are given to the worker, which later earn the worker a reputation-based salary in fungible fiat currency. The calculations suggest a compromise by setting a short lifetime for the REP tokens. In that case, under equilibrium conditions, the time between earning the fees and REP tokens and receiving the entire monetary payment is exactly the expiration time.
- A proportion of the fees may be given to supplementary DAOs, such as governance, development, oracles, etc. This may be considered the DAO’s overhead. This is mathematically equivalent to VI.1. It is also easy to calculate the result, since we can simply redefine the fee to be and all calculations hold. However, since this number can itself change nonlinearly in time, independently of how changes, it is worth stating the results. For instance, under different seasons of governance, such as when capital is invested in development, then REP tokens minted at different times will earn different fees due to differing overhead.
- The lifetime after which a token expires. The default assumption is . The token can be programmed to maintain full potency until it expires, or dwindle in power according to an attenuation function. In traditional finance, the lifetime is often referred to as its maturity, or expiration, meaning the initial length of a contract upon its inception. The tenor is the length of time remaining in the lifetime of a financial contract, .
Fundamental results
The basic results from which all other applications can be derived are summarized in the following theorems, which give the present value of a single REP token when it is minted.
Theorem 1 (Infinite Life Tokens)
where . The reputational salary of a single token is therefore given by the income stream
The present value at time of a single token in a DAO is
(Constant fees)
Assume the DAO is in the market position of earning fees with a constant rate and the lifetime of a token is infinite, .
Then the reputational salary of your single REP token is
and the present value is
Theorem 2 (Finite Life Tokens)
Assume the REP tokens have finite lifetime Then the total number of active REP tokens at any time is
Then, assuming a single token was minted at time the fees it earns is given by
(Constant Fees)
Now assume the rate of fees is constant. At any time after the DAO reaches token number equilibrium, there will always be tokens in the system. The income stream of a single token is then
and the present value of 1 token at time when it is minted is
(Exponential Fees)
Now assume a DAO has exponentially growing fees and lifetime . After the DAO has been running units of time, the number of active tokens will grow at a proportional exponential rate. The income stream of a single token is then
with present value
