Variables, Equations and the State

Token Mechanics Diagram

Coming from the causal loop diagram, the diagram below goes a level deeper to define the relationships between the variables mathematically.
​
​

Variables & Equations

Mathematical definitions of the variables and the relationships between them are as shown below:

Queries

Qcᵢ: Number of queries from Connector i, i ∈ [1, n] Qcuᵢ: Number of queries from Curator i, i ∈ [1, n] Qhᵢ: Number of queries from Hollower i, i ∈ [1, n] Quᵢ: Number of queries from User i, i ∈ [1, n] Qutot: Total user queries by users Qbriᵢ: # of queries bridger i’s content received Qbritot: Total # of received queries by all bridgers Cqᵢ: # of content per query for Connector i, i ∈ [1, n]
Qutot=∑i=1nQuiQutot = \sum_{i=1}^{n} Qu_i
​
Qbritot=∑i=1nQbriiQbritot = \sum_{i=1}^{n} Qbri_i

Fees

DBFq: DBaaS Fee Per Query DBFhᵢ: Fees collected from Hollower i, i ∈ [1, n] DBFtot: Total DBaaS Fees Collected
DBFhi=DBFq∗QhiDBFh_i = DBFq * Qh_i
DBFtot=∑i=1nDBFhiDBFtot = \sum_{i=1}^{n} DBFh_i
​
​
PFq: PaaS Fee Per Query PFcᵢ: Fees collected from Connector i, i ∈ [1, n] PFtot: Total PaaS Fees Collected
PFcqi=PFq∗QciPFcq_i = PFq * Qc_i
PFtot=∑i=1nPFcqiPFtot = \sum_{i=1}^{n} PFcq_i
​
SSFq: SSaaS Fee Per Query SSFcuᵢ: Fees collected from Curator i, i ∈ [1, n] SSFtot: Total DBaaS Fees Collected
SSFcui=SSFq∗QcuiSSFcu_i = SSFq * Qcu_i
SStot=∑i=1nSSFcuiSStot = \sum_{i=1}^{n} SSFcu_i
Ftot: Total Fees Collected
Ftot=PFtot+DBFtot+SSFtotFtot = PFtot + DBFtot + SSFtot

Reward Rates

RRuser: User Rewards Rate RRbrid: Bridger Rewards Rate RRfb: FirstBatch Revenues Rate
RRuser+RRbrid+RRfb=1RRuser + RRbrid + RRfb = 1

Reward Amounts

Rutot: Total User Rewards Rbritot: Total Bridger Rewards Rfb: FirstBatch Revenues Ruᵢ: User i’s rewards, i ∈ [1, n] Rbriᵢ: Bridger i’s Rewards, i ∈ [1, n] Rfb: FirstBatch Revenues
Ftot=RutotRRuser=RbritotRRbrid=RfbRRfbFtot = \frac{Rutot}{RRuser} = \frac{Rbritot}{RRbrid} =\frac{Rfb}{RRfb}
Rbrii=RbriTot∗QbriiQbritotRbri_i = \frac{RbriTot * Qbri_i}{Qbritot}
Rui=Rutot∗QuiQutotRu_i = \frac{Rutot * Qu_i}{Qutot}

Utility Function

The utility function of the protocol is given by a coub-douglas productivity function of bridger and user rewards, divided by an exponential function of the personalization fees per query. This equation expresses the positive effect bridger and users rewards have on the ecosystem while still accounting for the negative effect of query fees:
U(BriRq,UserRq,PFq)=BriRqaa+b⋅UserRqba+bePFq,where aa+b=RRbridandba+b=RRuserU(BriRq, UserRq, PFq) = \frac{BriRq^{\frac{a}{a+b}} \cdot UserRq^{\frac{b}{a+b}}}{e ^ {PFq}},\\ \quad \text {where } \frac{a}{a+b}=RRbrid \quad and \quad\frac{b}{a+b}=RRuser
U(BriRq,UserRq,PFq)=BriRqaa+b⋅UserRqba+bePFq,where aa+b=RRbridandba+b=RRuserU(BriRq, UserRq, PFq) = \frac{BriRq^{\frac{a}{a+b}} \cdot UserRq^{\frac{b}{a+b}}}{e ^ {PFq}},\\ \quad \text {where } \frac{a}{a+b}=RRbrid \quad and \quad\frac{b}{a+b}=RRuser
​
Lagrange multipliers equation of the Coub-Douglas part of the utility function and its first order conditions can be calculated as:
L=BriRqa⋅UserRqb+λ(Qbritot⋅BriRq+Qutot⋅UserRq−Ftotxfb)\begin{aligned} L &= BriRq^a \cdot UserRq^b + \lambda(Qbritot \cdot BriRq + Qutot \cdot UserRq - Ftot_{xfb}) \end{aligned}
∂L∂BriRq=aBriRqa−1∗UserRqb+λQbritot=0 \frac{\partial L}{\partial BriRq} = aBriRq^{a-1} * UserRq^b + \lambda Qbritot = 0
∂L∂UserRq=bBriRqa∗UserRqb−1+λQutot=0\frac{\partial L}{\partial UserRq} = bBriRq^a * UserRq^{b-1} + \lambda Qutot = 0
​
​
∂L∂λ=Qbritot∗BriRq+Qutot∗UserRq−Ftotxfb=0\frac{\partial L}{\partial \lambda} = Qbritot * BriRq + Qutot * UserRq - Ftot_{xfb} = 0
​
​
The monetary policy of the protocol is dynamically managed by controlling reward rates and fee amounts while satisfying the first-order conditions above. Fees for the Similarity Search as a Service and DataBase as a Service are based on traditional SaaS pricing methods.

State

The state of the token ecosystem is defined as a combination of 7 sections. Protocol-wide variables are under the first two sections; exogenous variables (fee amounts and reward rates) are continuously updated to determine the monetary policy, and endogenous variables keep track of the sums created by the agents’ actions. The other sections keep data related to unique agents for each role. The state as the ecosystem from a high level is as such:
{Protocol ExogenousProtocol EndogenousFirstBatchUsersConnectorsCuratorsHollowers}\left\{ \begin{matrix} \text{Protocol Exogenous} \\ \text{Protocol Endogenous} \\ \text{FirstBatch} \\ \text{Users} \\ \text{Connectors} \\ \text{Curators} \\ \text{Hollowers} \end{matrix} \right\}
​
The set above has multiple subsets and matrices as its elements as seen in the code snippet below:
