Filtering Monitor + Uptime · Robinhood Chain 4663 · week 2026-W36
Who was filtered, and whether the sequencer kept its clock
The ArbFilteredTransactionsManager precompile (0x…0074) lets the sequencer register transaction hashes that are then force-included with status 0. This page counts every registration since genesis, checks each hash's fate, and watches the chain's clock two ways: block-timestamp gaps, and wall-clock stalls of the head seen from outside.
Uptime
Sequencer head at render time: LIVE (block 56,067,150 is 1 s old; alert threshold 120 s, halt threshold 900 s).
Halts by block-timestamp gap (threshold 60 s)
| start block | end block | start (UTC) | gap s | |||||
|---|---|---|---|---|---|---|---|---|
| none recorded | ||||||||
Wall-clock stalls seen by the tail monitor
| observed (UTC) | head block | stalled s | ||||||
|---|---|---|---|---|---|---|---|---|
| none recorded | ||||||||
Test case: the press-reported 14-minute halt of 2026-09-04 ≈ 12:57Z leaves no block-timestamp gap (every 20,000-block step in that window spans 2,000–2,083 s); a halt of that kind is only visible as a wall-clock stall, which is why the second signal exists.
Filtered transactions
Registrations since genesis: 1,351 rows over 1,351 distinct hashes (last registration block 51,457,918). Fate: included with status 0: 1,349, never included: 2.
