Feedback is requested on whether to deprecate or keep this command line option in future releases. +Reindexing changes +------------------ + +In earlier versions, reindexing did validation while reading through the block +files on disk. These two have now been split up, so that all blocks are known +before validation starts. This was necessary to make certain optimizations that +are available during normal synchronizations also available during reindexing. + +The two phases are distinct in the Bitcoin-Qt GUI. During the first one, +"Reindexing blocks on disk" is shown. During the second (slower) one, +"Processing blocks on disk" is shown. + +It is possible to only redo validation now, without rebuilding the block index, +using the command line option `-reindex-chainstate` (in addition to +`-reindex` which does both). This new option is useful when the blocks on disk +are assumed to be fine, but the chainstate is still corrupted. It is also +useful for benchmarks. + Removal of internal miner -------------------------- |
