Each transaction ID appears once: present in both snapshots, observed only in source A snapshot, or observed only in source B snapshot.
Node-by-node distributions
How does each current mempool look?
Shared axes use the selected lens and snapshot metric. Absence from one node is not evidence of rejection.
Composition by lens · Source A
Virtual-size share per independent classifier lens.
Composition by lens · Source B
Virtual-size share per independent classifier lens.
Fee structure · Source A
Stacked virtual size per log fee-rate bin by script-profile group.
Fee structure · Source B
Stacked virtual size per log fee-rate bin by script-profile group.
Ancestor fee rate · Source A
Delta-adjusted ancestor fees over ancestor virtual size.
Ancestor fee rate · Source B
Delta-adjusted ancestor fees over ancestor virtual size.
Fee rate × size · Source A
Virtual-size density with marginals, normalized within this source.
Fee rate × size · Source B
Virtual-size density with marginals, normalized within this source.
Bucket × age · Source A
Column width is each script-profile group's virtual-size share; cells split the group by age at observation.
Bucket × age · Source B
Column width is each script-profile group's virtual-size share; cells split the group by age at observation.
Data carriage · Source A
Recognized carried bytes by data-carriage-shape group. The value is a conservative lower bound across OP_RETURN and registered carrier shapes.
Data carriage · Source B
Recognized carried bytes by data-carriage-shape group. The value is a conservative lower bound across OP_RETURN and registered carrier shapes.
Inputs × outputs · Source A
Virtual-size density across input and output counts, normalized within this source.
Inputs × outputs · Source B
Virtual-size density across input and output counts, normalized within this source.
Entanglement · Source A
Unconfirmed mempool relatives reported by this source.
Entanglement · Source B
Unconfirmed mempool relatives reported by this source.
Total output value · Source A
Total output value per transaction by script-profile group.
Total output value · Source B
Total output value per transaction by script-profile group.
Policy questions
Where do current policy outcomes differ?
Each row represents one node's membership population, partitioned by policy result. Transactions present in both snapshots appear once for each node.
| Population | Compatible | Would violate deployed policy | Indeterminate | Unassessed |
|---|
Atlas applies the same BIP-110 evaluator to each source-local transaction and prevout set; these are not verdicts reported by the nodes. Violation totals include complete and partly unresolved assessments. Rule-combination controls show only exact assessments. Unassessed transactions are pending while their source is classifying and unavailable after its pass completes or pauses.
