(Querying the full mempool and blocks at verbosity level 3 for fee info can be slow. Performance seemed fine to me, but might warrant some consideration) |
When fetching the coinbase for a block, specify the blockhash so it doesn't need txindex to identify a miner.
Extend TxSearchState with a per-block transaction list (TxListEntry) and a mempool flag. Add perform_block_search() using getblock verbosity 3 to fetch full tx objects with prevout values, enabling fee calculation without extra RPC calls. Add perform_mempool_search() using verbose getrawmempool, with cluster mempool chunk feerate support and sorting by mining priority. Also accept an optional blockhash hint in perform_tx_search() so confirmed tx lookups work without txindex, and bump sat/vB display precision from 1 to 2 decimal places.
Rename the Mempool tab to Explorer and add an interactive block/mempool
browser with three panes:
1. Block selector: a "Mempool" column alongside the existing
animated recent-block columns. Left/Right navigates, Down focuses.
2. Summary pane: mempool stats when the mempool column is selected,
or full block details (hash, time, difficulty, miner, etc.) when
a block is selected.
3. Transaction list: scrollable list of txs sorted by feerate (for
mempool) or in block order. Shows index, feerate (sat/vB), and
txid. Up/Down navigates, Enter drills down into the existing tx
overlay, PageUp/PageDown for fast scrolling.
Mempool data auto-refreshes every 30 seconds while browsing, with
selection preservation across refreshes. Block data is fetched on
demand and cached.

Rebased. Add a commit so miner field gets populated for searched blocks even without txindex. |

To be honest, i'm kinda torn about this one. I really like certain aspects but it's also a lot of information. I would like to push back this change for when we have config file (to not completely replace the mempool tab). |

Could have an "advanced" mode toggle that makes more information available, and when it's off, just show the mempool summary, blocks animation thing, no individual transactions, and not allow navigating? Could also look at things like bitcoin/bitcoin#8550 (which proposed a graph of mempool size/minfee over time) or just having a graph of the mempool current feerate diagram ( |
Presumably this should become a lua-based tab; if the ability to do (a) display the blocks graph, (b) select blocks, (c) display a summary vs a table; and (d) select txs and pop up an overlay window were exposed to lua. |

Converts the "mempool" tab into a "block explorer" tab, with the ability to browse transactions in blocks and the mempool.
