c6ca2b85a3e6e73674e210aee4ed69c4af2848e4 validation: do not wipe utxo cache for stats/scans/snapshots (Pieter Wuille) 7099e93d0a80c65a547131d7bab977b09573310c refactor: rename `FlushStateMode::ALWAYS` to `FORCE_FLUSH` (Lőrinc) Pull request description: Revival of https://github.com/bitcoin/bitcoin/pull/30610#issuecomment-3432564955 with the remaining comments applied on top > Since #28280, the cost of a non-wiping sync of the UTXO cache is only proportional to the number of dirty entries, rather than proportional to the size of the entire cache. Because of that, there is no reason to perform a wiping flush in case the contents of the cache is still useful. > > Split the `FlushStateMode::ALWAYS` mode into a FORCE_SYNC (non-wiping) and a FORCE_FLUSH (wiping), and then use the former in `scantxoutset`, `gettxoutsetinfo`, snapshot creation.

Bitcoin Core
Setup
Bitcoin Core is the original Bitcoin client and it builds the backbone of the network. It downloads and, by default, stores the entire history of Bitcoin transactions, which requires several hundred gigabytes or more of disk space. Depending on the speed of your computer and network connection, the synchronization process can take anywhere from a few hours to several days or more.
To download Bitcoin Core, visit bitcoincore.org.
Running
The following are some helpful notes on how to run Bitcoin Core on your native platform.
Unix
Unpack the files into a directory and run:
bin/bitcoin-qt(GUI) orbin/bitcoind(headless)bin/bitcoin(wrapper command)
The bitcoin command supports subcommands like bitcoin gui, bitcoin node, and bitcoin rpc exposing different functionality. Subcommands can be listed with bitcoin help.
Windows
Unpack the files into a directory, and then run bitcoin-qt.exe.
macOS
Drag Bitcoin Core to your applications folder, and then run Bitcoin Core.
