v2.0.0

2020-03-25

• New data points in homepage "Network Summary":
  • Fee estimates (estimatesmartfee) for 1, 6, 144, 1008 blocks
  • Hashrate estimate for 1+7 days
  • New item for 'Chain Rewrite Days', using 7day hashrate
  • New data based on UTXO-set summary. Note that UTXO-set querying is resource intensive and therefore disabled by default to protect slower nodes. Set BTCEXP_SLOW_DEVICE_MODE to false in your .env file to enjoy associated features:
    • UTXO-set size
    • Total coins in circulation
    • Market cap
  • 24-hour network volume (sum of tx outputs). This value is calculated at app launch and refreshed every 30min.
  • Avg block time for current difficulty epoch with estimate of next difficulty adjustment
• Tweaks to data in blocks lists:
  • Simpler timestamp formatting for easy reading
  • Include "Time-to-Mine" (TTM) for each block (with green/red highlighting for "fast"/"slow" (<5min / >15min) blocks)
  • Display average fee in sat/vB
  • Add total fees
  • Add output volume (if getblockstats rpc call is supported, i.e. 0.17.0+)
  • Show %Full instead of weight/size
• Block Detail page improvements
  • New data in "Summary" on Block pages (supported for bitcoind v0.17.0+)
    • Outputs total volume
    • Input / Output counts
    • UTXO count change
    • Min / Max tx sizes
  • New "Fees Summary" section (bitcoind v0.17.0+)
    • Fee rate percentiles
    • Fee rates: min, avg, max
    • Fee totals: min, avg, max
  • New "Technical Details" section. Items from "Summary" in previous versions have been moved here. This section is collapsible if desired.
• Improvements to transaction input/output displays
  • Change primary input data to be tx outpoint ("txid #voutIndex")
  • Zero-indexing for tx inputs/outputs (#173)
  • Labels for transaction input/output types
  • Inputs: when available, show "input address" below tx outpoint
  • Coinbase and OP_RETURN items: show ascii data inline with link to show hex data
• New tool /block-stats for viewing summarized block data from recent blocks
• New tool /mining-summary for viewing summarized mining data from recent blocks
• New tool /block-analysis for analyzing the details of transactions in a block.
  • IMPORTANT: Use of /block-analysis can put heavy memory pressure on this app, depending on the details of the block being analyzed. If your app is crashing, consider setting a higher memory ceiling: node --max_old_space_size=XXX bin/www (where XXX is measured in MB).
• New tool /difficulty-history showing a graph of the history of all difficulty adjustments
• Change /mempool-summary to load data via ajax (UX improvement to give feedback while loading large data sets)
• Zero-indexing for tx index-in-block values
• Reduced memory usage
• Versioning for cache keys if using persistent cache (redis)
• Configurable UI "sub-header" links
• Start of RPC API versioning support
• Tweaked styling across site
• Homepage UI tweaks
  • Remove "Bitcoin Explorer" H1 (it's redundant)
  • Hide the "Date" (timestamp) column for recent blocks (the Age+TTM is more valuable)
