TL;DR
This post analyzes further the proposals from the forum thread “Possible Optimization of Tokenomics”.
The primary method to balance supply and demand within the ICP ecosystem remains the continued growth of the cycle burn rate. Adjustments to inflation are likely to have a lesser impact.
In response to community feedback, the proposal to reduce neuron dissolve delays was modified to include an opt-in mechanism. If 25% of neurons opt in, the proposed changes would result in a modest 3.8% reduction in voting rewards. Given the community’s concerns and the limited impact, it is recommended not to pursue this proposal further.
The second proposal, concerning exchange maturity, has received relatively little attention and has been highlighted as complex by the community. Considering these factors, it is advised to table this proposal for now.
Analysis of Supply & Demand
Let us begin with an overview of the supply and demand within the ICP ecosystem.
The below graph covering January 2022 to April 2024 shows the monthly burn rate, measured in XDR (Special Drawing Rights). During this period, there was an impressive 11.6-fold increase in the burn rate.
The following graph compares the demand (cycles burned, based on a three-month average) to the supply, which includes node rewards and voting rewards. Currently, the cycles burned need to increase by 70 times to offset node provider rewards, at which point the ICP protocol would generate operational revenue. Furthermore, an additional 15-fold increase would be necessary to balance out the voting rewards (assuming that monthly voting rewards would be completely spawned to ICP and using the current ICP/XDR exchange rate).
These insights underscore the need for continued, significant growth within the ICP ecosystem. With major new features already released, such as integrations with Bitcoin and Ethereum blockchains, there is a substantial potential for further adoption. The ICP blockchain is well-positioned for expansion, and a single new successful use case could already dramatically increase the burn rate. Thus, focusing on enhancing the burn rate remains the crucial element for the tokenomics of the ICP ecosystem.
Impact assessment of Revised Proposal for Adjusting Dissolve Delays
Proposal Description:
This proposal introduces an opt-in mechanism allowing neurons to reduce their dissolve delays by a factor of ⅝. The process involves:
- Collecting all neurons wishing to reduce their dissolve delays
- Recalculating the total voting power (VP_new), which will be less than the current total voting power (VP_current), reflecting the adjusted dissolve delays.
- To ensure stability of voting rewards for neurons, voting rewards per unit of voting power need to remain unchanged. Therefore, the voting reward function will need to be adjusted in proportion to the VP_new / VP_current ratio.
Inflation Impact:
The inflation impact of this proposal directly correlates with the participation rate of neurons and their respective voting power. Based on data from the IC dashboard, which includes a breakdown of neurons by their stake and dissolve delay:
- If all neurons participate, the adjustment in the voting reward function would lead to a reduction of 15%.
- If only 25% of neurons opt in, the impact on the voting reward function would be a modest reduction of 3.8%.
Please note: Newly staked ICP will not affect inflation under this proposal, as the adjustment to the voting reward function is designed as a one-time action.
Conclusion
Proposal 1: Reduced Dissolve Delays
The analysis in this post shows that the primary method to balance supply and demand within the ICP ecosystem remains the growth of the cycle burn rate. Adjustments to inflation are likely to have a lesser impact.
Reacting to community concerns, Proposal 1 was adjusted with the inclusion of an opt-in mechanism. Assuming that 25% of neurons opt in, the proposed changes would result in a modest 3.8% reduction in voting rewards. Given this limited impact, pursuing this proposal further may not be worthwhile. It might be sensible to revisit the voting reward function at a later point in time.
However, a specific element of the proposal—reducing the minimum dissolve delay to three months—could be considered separately. This adjustment aims to attract new stakers by lowering the barrier to entry and merits discussion in a dedicated forum thread.
Proposal 2: Exchange Maturity
This proposal has received relatively little attention and has been noted for its complexity by the community. Given these factors, it is recommended to table this proposal for the time being.
