Monetary Policy
An overview of the monetary policy of POKT, including monetary phases and inflation.
Pocket's staking and inflation mechanisms enable a more efficient resource allocation structure by limiting the number of transactions (and thus block validation costs) to one-time staking transactions. All nodes are able to focus primarily on servicing and validating Relay requests by Applications, with minimal energy spent on block validation. By being eventually consistent and tying rewards directly to inflation, Service Nodes are in effect receiving micropayments for work validated by two parties without the need for constant on-chain fee payments.
Allocation of Minted POKT
For each Relay served and validated by the protocol, POKT is added to the next block reward according to the mint rate. The following is a breakdown of each participant's share of the block reward given no parameter changes.
| Participant | Parameter Name | Current Allocation |
|---|---|---|
Service Nodes | N/A | 85% |
Block Producer | 5% | |
DAO | 10% |
Current values of these parameters (and all others) can be found on the Protocol Parameters page.
The value for ProposerAllocation has recently changed. Please see PUP-19 for details.
As part of the Proof-of-Stake consensus, each Service Node has a weighted chance of being selected to be the block producer for any given block based on the total amount staked for that given node. The block producer receives a portion of the entire block reward, as does the Pocket DAO, which provides continuous and sustainable funding for supporting the continued adoption and utility of Pocket Network.
Monetary Phases
As the Pocket Network develops, we envision the POKT monetary policy evolving through three stages: Bootstrapping, Growth, and Maturity. The following sections will discuss each of these phases. Note that some of these ideas are forward-thinking and so are subject to change.
Bootstrapping Phase
During the bootstrapping phase of the network, it is important to build a strong foundation for the service, securing as many individual entities running nodes as possible. We do this by creating an environment where it is simple and inexpensive for initial Applications to access the network, and significantly profitable for Service Nodes to provide infrastructure.
Application usage and traction dictate the initial rewards that the Service Node pool will receive. By decreasing the barrier to entry for Applications (freemium access, low cost), the demand for Relays should be high during the Bootstrapping Phase, providing the initial pool of Service Nodes with ample opportunities to earn the high rate of POKT awarded for Relays serviced in the bootstrapping phase of the network.
As inflation and revenue increase per Service Node, the potential for competition increases, as rational, profit-seeking agents discover the protocol. This creates the flywheel to spur the network effects of Service Nodes purchasing and using POKT to participate until an equilibrium is found.
As the Protocol Throttling Formula adjusts to market demands, Applications being able to purchase more Relays results in more revenue for Service Nodes, further increasing the incentive for existing Service Nodes to re-stake their earned POKT. Increased participation in Pocket Network from Applications and Service Nodes ultimately benefits all parties by providing new revenue opportunities for Service Nodes and improving the service and resilience of the network for Applications. Due to Pocket Network being a permissionless Proof-of-Stake protocol and Service Nodes having an extremely low marginal cost of operation, the barriers to entry are significantly lower compared to Proof-of-Work mining based protocols. Pocket's economic primitives incentivize a diverse set of entities and individuals such as data centers, existing infrastructure providers and hobbyists to participate as node operators within the network.
Growth Phase
The growth phase is the period from launch which will see the greatest increase in the overall ParticipationRate of the protocol. When Applications stake during the growth phase, they earn more MaxRelays as the network grows (assuming they un-stake and re-stake), and don't pay for anything else until the network has matured and the Application Burn is activated.
One result of this is inflation. It is a priority of the DAO to manage inflation in a manner that encourages sustainable growth of the Pocket ecosystem, protects rewards against a potential decrease in relays, and sensibly updates rewards as Pocket Network grows.
If both sides of the marketplace (Applications and Service Nodes) grow, there will be continuous demand for Relays resulting in Service Nodes spinning up new Pocket nodes to increase the number of Relays they can service.
Early Applications will receive more infrastructure throughput as the network grows providing an incentive to early adopters of the network. When both the percentage of POKT staked and Service Node margins begin reaching their equilibrium, the protocol will have entered its maturity phase.
See the section below on inflation for more details.
Maturity Phase
While the Growth Phase is inflationary, designed to incentivize active participation and supply-side staking for the security of the network, the Maturity Phase is designed to ensure the long-term sustainability of Pocket. The Maturity Phase is defined as the point in which Pocket Network has crossed equilibrium and the growth in inflation begins outpacing growth in the total staked supply of POKT.
This shift to long-term sustainability revolves around burning POKT to ensure the POKT supply is stable doesn't lose its value as a form of consideration to Service Nodes. In this phase, Pocket becomes similar to traditional Software as a Service pricing models, where Applications must "top up" their stakes periodically to avoid going below their needed Relay limit.
This should result in a decline in the ParticipationRate and Service Node margins due to an imbalance from more supply than demand for POKT.
In addition, to ensure the continued sustainability of POKT, to retain reasonable margins for Service Nodes, and to eliminate unnecessary overinflation of POKT, the Pocket DAO may activate an Application Burn Rate (ABR) at the Maturity Phase. This means that any POKT minting is balanced out by Application stake being burned at the same rate.
Once activated, the ABR results in a shift from Applications paying through dilution, to Application POKT being burned on a block by block basis to balance the minting of POKT as inflation awards to Service Nodes.
The effect of this is a logarithmic decay until the minimum App stake of 1 POKT is reached. Unless an Application increases the number of POKT they have staked, their holdings will fall under their desired amount causing applications to "top up" their stakes turning the network into a self-sustaining SaaS-like infrastructure protocol.
The rate of Application burn is determined by using indicators such as the decay in the growth of Application and Service Node stake over time.
POKT Inflation
Overview
As the number of Nodes grows in the Pocket ecosystem, if we assume a constant per-relay payout, it follows that the total amount of POKT generated by the nodes will increase. While POKT was designed to be permanently inflationary, the high rate of inflation which this situation causes has strong repercussions for the network itself.
There are plenty of benefits to inflation, such as attractive rewards for new and existing participants, near term buying pressure from new node runners, and the ability to bootstrap new chains more easily. And excitement in the marketplace driven by node rewards can lead to increased adoption.
However, there are many drawbacks to excessive inflation, such as sell pressure which may reduce activity on the network, network underutilization and unnecessary hardware costs, and a general perception of long-term unsustainability.
With this in mind, the DAO has voted on implementing and ongoing adjustment to the value of the rewards per relay (in parameter form, known as RelaysToTokensMultiplier).
For more information and to read the actual DAO proposals on inflation management, please see the following:
Inflation management
The DAO's currently approved inflation management framework is called the Weighted Annual Gross Max Inflation rate (WAGMI).
A WAGMI target of 100% was implemented on Feb 28, 2022, which corresponds to a per-node reward of 0.008461 POKT/relay. It was previously set to 0.01 POKT/relay.
WAGMI targets will be stepped down to 50% over the following five months as follows:
| Date | WAGMI Target Inflation Rate |
|---|---|
Feb 28, 2022 | 100% |
Mar 26, 2022 | 90% |
Apr 25, 2022 | 80% |
May 25, 2022 | 70% |
Jun 24, 2022 | 60% |
Jul 24, 2022 | 50% |
The per-node reward (also known by its parameter value RelaysToTokensMultiplier) is calculated using:
The 30-day trailing average of daily relays at the time of each adjustment
The total supply at the time of the proposal passing ("Total Supply Baseline"):
The timestamp of the proposal was Feb 24, 2022, 6:37 GMT (block height: 51909), and the Total Supply Baseline was 945,014,989 POKT.
Also note that the DAO is empowered to recalculate the mint rate more frequently than the above monthly schedule in times of sharp increases or decreases in the amount of relays. In this case, a weekly recalculation may occur.
Recent recalculations:
| Date | Target inflation rate | Approx. 30-day trailing avg. of daily relays | Mint rate | RelaysToTokensMultiplier |
|---|---|---|---|---|
[Initial] | N/A | N/A | 0.010000 | 10000 |
Feb 24, 2022 | 100% | 306,000,000 | 0.008461 | 8461 |
Mar 25, 2022 | 90% | 311,000,000 | 0.007498 | 7498 |
Apr 1, 2022 | 90% | 403,000,000 | 0.005776 | 5776 |
Apr 8, 2022 | 90% | 481,000,000 | 0.004847 | 4847 |
Apr 25, 2022 | 80% | 693,000,000 | 0.002988 | 2988 |
May 31, 2022 | 70% | 860,000,000 | 0.002109 | 2109 |
Jun 30, 2022 | 60% | 879,000,000 | 0.001768 | 1768 |
Jul 24, 2022 | 50% | 945,000,000 | 0.001371 | 1371 |
