As we’ve mentioned at various times in the previous
chapters, the data market is governed by a set of a
parameters dictated within
parameters govern the function of the market by setting
various critical settings. These parameters can be
modified via a stakeholder vote.
In this chapter, we’ll review the parameters that govern the data market. Most of these should seem similar, since you’ll have run into them already earlier in the book.
The stake (in
MarketToken wei) needed to issue a
challenge to a listing. This parameter is of type
The time (in seconds) that a poll should remain open.
This controls the length of the voting window in which
council members can vote upon an
challenge, or reparameterization. This parameter is of
The percent (whole number between 0 and 100) of the vote needed by a candidate to pass in a poll. This parameter is of type uint256
The price floor for purchasing
MarketToken via the
algorithmic price curve. This parameter is of type
The spread which is rewarded to the market when
MarketToken via the algorithmic price
curve. This parameter is of type
The number of new
MarketToken wei that are minted
when a listing is listed. This parameter is of type
The cost to purchase a byte of data from the market. This parameter is of type wei_value
The percentage of a delivery payment that’s alloted to the backend. Must be a percentage between 0 and 100. This parameter is of type uint256
The percentage of a delivery payment that’s alloted to the maker. Must be a percentage between 0 and 100. This parameter is of type uint256
All market parameters can be changed with a vote. The process of changing data market parameters is referred to as reparameterization. The same voting mechanism is used for reparameterization as for other market processes. That is, a reparameterization candidate is created, and put up for vote as described in the voting chapter
We’re finally done learning about all 7 contracts in the Computable ecosystem! This is a big milestone. At this point, you should have gained an understanding of the on-chain economic dynamics that control a data market. This means it’s now time to start learning about the off-chain parts of a data market. In particular, let’s pin down what a datatrust’s off-chain parts actually do. You’ll learn more in the next chapter.
