The maturity test and the two 20 percent thresholds

The definition is short. The test is not.

The statutory definition in the House-passed text is one sentence. A mature blockchain system is a blockchain system, together with its related digital commodity, that is not controlled by any person or group of persons under common control.

Everything operational sits in the certification criteria added as Exchange Act Section 42. Those cover whether the system is functional, whether the code is open source, whether it runs on pre-established transparent rules, whether anyone holds unilateral authority to materially alter it, and how ownership is distributed. The first few are close to free for any serious protocol. The ownership conditions are where the framework bites.

Two thresholds, and the popular version is wrong

You will read everywhere that holding 20 percent of a token defeats maturity. That is not what the text says, and the error matters.

The first threshold is about governance. No person may have unilateral authority to control or materially alter the system, or control 20 percent or more of the outstanding voting power. Voting power is not the same as tokens held, particularly on chains where most supply never votes.

The second is about insiders. The digital commodity issuer, related persons and affiliated persons must not beneficially own, in aggregate, 20 percent or more of total units. Affiliated-person status keys off acquiring 5 percent or more from the issuer. Related-person status keys off 1 percent.

So an unaffiliated whale holding 25 percent does not break the test. A founding team, its foundation and its seed investors adding up to 21 percent does. The rule targets the cap table, not the rich list, and that flips which tokens should actually worry.

Why 20 percent of insider supply is a hard bar

Because it is close to the median founding allocation. A typical 2021 to 2023 launch reserved roughly 15 to 25 percent for the team, another 15 to 20 percent for investors, and a further slice for a foundation treasury. Counted in aggregate, as the text requires, a large share of the market fails on arithmetic alone.

The live question is who counts as affiliated. The 5 percent and 1 percent triggers are broad enough to sweep in most early backers, which is what makes the aggregate test bite. Early Thunder ran insider concentration across our 251-token scorecard to size the exposure, and the distribution is published in full.

What the test does not measure

It says nothing about whether governance is meaningful, whether a multisig can pause the chain, or whether validator and sequencer sets are concentrated. A protocol could pass on distributed ownership while five entities run the infrastructure.

Treat maturity as a supply and governance-power screen with a decentralisation label on it. It is a defensible place to draw a legal line because both are measurable. It is not the same as being decentralised, and a passing grade should not be read as one.

One more caution. Definitions in this area moved between the House text, the Senate substitute reported on June 1 2026, and the merged text of July 22 2026. Anything you read about this test should tell you which document it is describing.
