According to the official token issuance model (From Space Race to Long Tail: Crafting a Sustainable Token Issuance Model for a Resilient Autonomys Network | by Autonomys Network | Autonomys Network | Medium), we can know the following facts about the design of the economic model:
- On average, each block contains 9 votes
- In the early stage of the main network, the total income of each height is 5 ATC, the expected income of vote is 0.9 * 0.5 = 0.45, and the expected income of block is 0.5 + 9 * 0.5 * 0.1 = 0.95
The first point can be verified by referring to the network parameters set in the latest official code:
/// Number of votes expected per block.
///
/// This impacts solution range for votes in consensus.
const EXPECTED_VOTES_PER_BLOCK: u32 = 9;
But in fact, the author Venus-IPFSForce counted the network data of the main network in the past three days (November 23 to November 25), and found that the block generation behavior of the main network did not meet expectations:
block count | block reward | vote count | vote reward | ratio of block count and vote count | |
---|---|---|---|---|---|
11月23日 | 14638 | 0.908047547479164 | 147066 | 0.408864047434485 | 0.0995335427631132 |
11月24日 | 14488 | 0.905646051905025 | 144927 | 0.408923113015518 | 0.0999675698800086 |
11月25日 | 14486 | 0.900938837498274 | 143464 | 0.408625160318965 | 0.100973066413874 |
It can be found that the ratio of block to vote is not 1:9 as originally designed, but 1:10, which leads to a decrease in the average revenue per solution.
This anomaly will cause the Total Space Pledged to be underestimated by about ten percentage points.
Apart from chain reorg, this is the main reason why everyone’s calculated single T benefits are not as good as the theoretical benefits.
