The point
Yes, the rules behind a crypto index can change. Eligibility screens, weight caps, and rebalancing cadence can all move over an index's life. What actually matters is whether anyone outside the firm making that change saw it before it took effect. A dated record after the fact is a lower bar, and it is the one most crypto methodologies, ours included, currently clear.
What actually counts as a rule change
A rebalance is the rule executing exactly as written. Nothing about the rule itself moves that day. A rule change is different. It works on the rule, not the outcome: an eligibility screen gets redrawn, a weight cap moves, or a new trigger gets added that forces a review outside the calendar.
The rule decides which coins even qualify before a single weight gets assigned. That screening step is the basic shape of a crypto index to begin with. A reader who wants the mechanics behind it can read why you cannot pick the coins inside a QSI index.
What it looks like when an outside check exists
Mainstream finance handles a change to a benchmark index differently. A stock market index is expected to be transparent, meaning its construction methods are specified in writing. That standard has applied to large equity indices for decades. It should not stop applying the moment the word "crypto" enters the sentence.
S&P Dow Jones Indices runs a proposed methodology change through a public consultation before its Index Committee decides. Consultations "provide an opportunity for any member of the public to submit input." The Committee reviews every response it gets. It keeps final discretion over the outcome, and the proposal, the reasoning, and the decision all stay visible while that happens.
International principles written for financial benchmarks go further. They treat governance, methodology quality, and accountability mechanisms as standards in their own right, alongside performance. A change made well is one an outsider could see coming, and could question, before it locked in.
What it looks like when no outside check exists
Most of the crypto index category runs the other way today. A rule changes. Nobody outside the firm saw it proposed. Nobody outside the firm saw it decided. The only evidence a change happened is that the number reads differently this month than it did last month.
An investor holding through that has no way to tell whether the change came from a documented review or from someone's judgment call on a bad day. An investor who joined during one calibration and is still holding three years later has a real question. Is the rule governing their basket today the one they signed up under, and if it moved, when and why. Over years of monthly rebalances, a gap like that compounds quietly. By the time it matters, the screen or cap that applied on day one may no longer be the one running the basket.
Where Qatobit's own practice actually sits
What the methodology promises
Qatobit's own methodology is a living document under change control. It is written down, versioned, and dated. When it changes, the version it replaced stays readable instead of disappearing. That clears the lower bar: a record exists, and it survives the announcement. QSI GEQ8's own methodology holds its stated weight caps to that same discipline.
It does not yet clear the higher bar S&P Dow Jones Indices sets. Nobody outside Qatobit reviews a proposed change to a QSI index's methodology before it locks in. The category is younger than equity indexing by decades. Naming that gap plainly is more honest than pretending it is closed.
What we publish and what we hold back
Qatobit publishes the framework for how a weight gets set and the caps it cannot cross, for every QSI index, before the platform even opens to a deposit. What it keeps proprietary is the exact target weight sitting inside a basket on any single day.
A static weight printed today is stale the moment the next rebalance runs, so publishing it would misrepresent the live state of the basket rather than describe it honestly. The specific calibration, the exact numbers rather than the logic that sets them, is also the part every serious index keeps to itself while publishing how the logic works. Verifying the rule and verifying every number the rule produces on a given day are two different exercises.
The question worth asking any provider
So yes, the rules can change. A version you can still open next to the one it replaced is the lower bar, and it is worth checking for. Whether anyone outside the firm saw the change coming before it locked in is the harder, more useful question. Qatobit cannot answer yes to that second question yet, and saying so plainly matters more than a comforting answer would.
Ask any provider, ours included, where its version history lives and who reviewed the last change before it went live. A provider with no answer to either question is asking you to trust a rule nobody is checking. The five-point framework for evaluating any crypto index methodology covers the other checks worth running on the same page: eligibility, weighting, cost, and transparency.
Frequently asked questions
Does a crypto index's methodology ever change?
Yes. Eligibility screens, weight caps, and rebalancing cadence can all be revised over an index's life. What decides whether the revision is trustworthy is whether anyone outside the firm reviewed it before it took effect. Getting it recorded afterward is a lower bar on its own.
What is the difference between a rebalance and a rule change?
A rebalance is the existing rule executing on schedule: trimming what has grown, topping up what has lagged. A rule change works on the rule itself, such as a new eligibility screen, a moved weight cap, or an added trigger for an off-cycle review.
Who reviews a crypto index's rule before it changes?
For QSI indexes, a change runs through the same documented change control the methodology describes: written down, versioned, and dated, with the previous version left readable. Nobody outside Qatobit reviews a proposed change before it goes live today.
Do mainstream stock indices handle rule changes differently?
Some do. S&P Dow Jones Indices runs a proposed methodology change through a public consultation before its Index Committee decides, so outside stakeholders can comment before the change locks in. Qatobit does not yet run an equivalent public step.
Why doesn't Qatobit publish its exact index weights?
A static weight printed today is already out of date after the next monthly rebalance. The specific calibration is the part every serious index keeps to itself while publishing the logic that sets it. The rule for how a weight is derived, and any change to that rule, stays public regardless.
