Method reference
trace_block
Parity-style traces for every transaction in a block: internal calls, contract creations, self-destructs, and rewards. Where receipts tell you a transaction succeeded, traces show the internal value flow it caused.
Indexers reconstructing internal transfers — analytics pipelines, subgraph-style systems, accounting tools — depend on the trace namespace. Like debug_*, availability depends on upstream node software and operator policy.
