Sheridan, WYOMING, Sept. 29, 2026 (GLOBE NEWSWIRE) -- Robinhood Chain did not stop producing blocks on 4 September 2026, despite widely circulated reports of an outage of about 14 minutes, according to findings published today by Glass Hull, the independent measurement practice of Jet Fyul Dynamics LLC. Glass Hull built its own full copy of the chain's permanent record, measured it by two independent methods, and published its core findings as sealed Proof Posits, signed by two hardware devices and anchored in Bitcoin, so that anyone can check the result.
Robinhood Chain kept producing about 590 blocks a minute on 4 September 2026, through both pauses in its posting to Ethereum (shaded) and past the reported 12:57 UTC outage time. Source: Glass Hull, Proof Posit PP-005, sealed and anchored in Bitcoin.
On 4 September the chain produced 854,255 blocks carrying 13,978,496 transactions, never more than 2 seconds apart. What paused was the chain's posting of data to Ethereum: twice, between 12:29 and 12:48 UTC, for 14 minutes in total. Both pauses ended before the 12:57 UTC start time given in published reports. Arbitrum stated the same day that the chain "experienced no downtime."
"Claims about Robinhood Chain have outrun anyone's ability to check them," said K. L. Phillips, CEO of Jet Fyul Dynamics. "We didn't add another opinion. We measured the chain's own record, sealed what we found so it can't be quietly revised, and published the means for anyone to check us."
Findings published today include:
- The chain never halted (Proof Posit PP-005): since public mainnet opened on 1 July 2026, Robinhood Chain has never gone more than 16 seconds without a block.
- Failed transactions still pay (Proof Posit PP-006): from genesis to 14 September, 119,984,049 of 653,008,422 user transactions failed (18.4%), paying about 1,551.08 ETH in fees.
- Fee coverage runs to year-end: Robinhood's published terms now cover network fees on eligible Robinhood Wallet swaps through 31 December 2026, not 29 September as widely reported. Glass Hull has sealed a notice recording the change against its own pre-registered study.
- Daily fees fell 94.12% from 3,333.81 ETH on 4 September to 195.97 ETH on 13 September.
- AMC's token: 295 of 386,668 AMC token swaps executed at 60 times or more above AMC's prior Nasdaq close, 293 of them in one 17-minute window on Sunday, 30 August; excluding dust-sized trades, the largest was at 73.4 times. That day was the only day the token traded at many times the stock: its typical trade that Sunday was 10.2 times Friday's close.
- The first hour decides a launch: using only a token's first hour of data, the top 1% of Glass Hull's model's picks graduated to a trading pool at about 67 times the base rate.
- Volume that never moved: counting swap events at face value shows $29.68 billion of USDG swap volume; $11.69 billion actually moved.
- Arbitrum's share: every Arbitrum Expansion Program settlement measured split exactly 90/10 (Proof Posit PP-003).
An anomaly held under notice. Glass Hull also traced a path from a multi-signature Safe to a newly created account whose holdings, across two readings, include tokenized instruments of AMC Entertainment and 69 other issuers. On 4 September that account received 35 stock tokens, each minted earlier that same day. Its full findings are reserved for the 72 parties concerned (Robinhood Chain, the Arbitrum Foundation, and 70 issuers), through Glass Hull's Gated Proof Posits page. No finding alleges conduct by any issuer, and publication of Glass Hull's findings never depends on any purchase.
"If your bytes differ from ours, kindly let us know publicly or privately," Phillips said. "A difference is still a finding."
An interactive Evidence Room lets readers replay every block of the reported window, compare both measurement methods and verify each seal: gh.jetfyul.com/evidence-room.
Glass Hull's method is set out in three working papers on SSRN. Its Proof Posits are free, and the complete methods behind the "never halted" and "failed transactions" findings are published free so that anyone with chain access can reproduce them.
