Glass Hull Evidence Room
Robinhood Chain never stopped.
On 4 September 2026, reports said the chain halted for about 14 minutes. Its own record shows 854,255 blocks that day, never more than 2 seconds apart.
Every figure in this room comes from the chain's own record and is checked by two independent methods.

Proof Posit PP-005
Block production never stopped.

Since public mainnet opened on 1 July 2026, the chain has never gone more than 16 seconds without a block.
Proof Posit PP-005, continued
What paused was posting to Ethereum.
Replay every block the chain produced from 12:29:47 to 12:48:11 UTC, from its own record. The clock shows measured time.
Sound is generated from the same measured block series: one tick per block. It represents the record; it is not a separate measurement.
Longest block gap in this window: 2 s
Blocks: 10,850, contiguous
Cause: not stated.
Ethereum's record shows the poster's bids for blob space exceeded the base fee in both pauses, so the base fee alone does not explain them. We state no cause.
Both arms: the same method finds real silences where they exist (pre-launch gaps of up to 252,948 seconds), so it would have caught a halt.

Proof Posit PP-006
Nearly one user transaction in five fails, and still pays.
- User transactions, genesis to 14 Sept653,008,422
- Failed119,984,049
- 119,984,049 ÷ 653,008,42218.374%
- Fees paid by failed transactions≈ 1,551.08 ETH
Proof Posit PP-003, sealed
Every settlement split exactly 90/10.
Robinhood Chain shares its revenue with Arbitrum through the Arbitrum Expansion Program. Across all nine settlements we measured, exactly 10.000% went to Arbitrum's ecosystem every time.
The largest, on 7 September 2026, was 12,725.576405 ETH: 11,453.018765 ETH to the operator's recipient and 1,272.557641 ETH to the ecosystem, 2.86 times the eight prior settlements combined.
That settlement was read at block 57,033,100 from a public archive endpoint, as the sealed Posit discloses.
How a Glass Hull proof is made
Two workers, one answer.
The figure is PP-006's measured count of failed transactions. The animation shows the process; it is not a measurement.
One worker is blue. One is red. They read the chain by independent routes and never share notes. If they return the same answer, down to the last digit, the answer does not depend on one tool or one bug. When they disagree, we do not publish.
A witness records every step. A rule-keeper, not a person, decides whether a result may be sealed. Two hardware notaries sign. The result is anchored in Bitcoin.

Why independence must be something you can check: two routes that must agree, a test built to catch us, a method you can re-run. - Phillips, SSRN 7444679 (2026)
Why the witness, the gate and the notaries: proving permission, refusal and behavior in automated systems. - Phillips, The Four Behaviors, SSRN 7365818 (2026)
What a serious operator must be able to prove, and why a gate that can't be talked round meets that standard.
Held under notice
A door we keep closed, for now.
We traced a chain of transactions ending in a new account that received tokenized instruments of AMC and dozens of other issuers, many within hours of their minting.
The parties concerned see it first: Robinhood Chain, the Arbitrum Foundation, and 70 issuers. We extend them at least as long as it took us to reach a conclusion.
No finding alleges conduct by any issuer.
