What does growth in a catalogue's listing count measure?
The short answer
Listed addresses, not sellers. In October most of the rise in the listed resource addresses of Coinbase's Bazaar came from one host, and with that host set aside the count rose far less.
As published in the issue
On 30 October, the count for datapackvibe was 71,664 of the Bazaar's 100,538 listed resource addresses. From 1 to 30 October, the count rose fivefold. Excluding that host, the number of listed resource addresses rose by about half, from 19,112 to 28,874.
(3) The CATALOGUE population: the listed resource addresses of Coinbase's Bazaar as each complete daily reading returned them between 1 and 30 October 2026, with the readings of 1 and 30 October as the anchors every rise is counted against, the reading of 30 September for the hosts no longer listed and the readings since late August for the hosts ever listed; a catalogue figure describes what the catalogue listed on the date named and never why.

What we measured
Each complete daily reading of Coinbase's Bazaar in October, counting the listed resource addresses and the hosts they sit on, with the month's opening and closing readings as the anchors every rise is counted against. The exact population rule is quoted beside the figure below.

What this does not say
- The October increase tells a buyer little about how many distinct sellers became available.

|---|---|---|
| Every complete daily reading of Coinbase's Bazaar between 1 and 30 October — 25 days, with 14 and 26–29 October holding none: the listed resource addresses and hosts of each reading, the largest host's count day by day, the hosts sharing one naming pattern, the hosts listed on 30 September and not on 30 October, and the three largest hosts at the close. Counts and host names; no row of the catalogue is carried. | f3e489659e2b3297ac84f314dd85fb560dacdc3305f54d919740299d66552fcc |
