25f69d970arelease note (Pol Espinasa)af629821cftest: add background validation test for getblockchaininfo (Pol Espinasa)a3d6f32a39rpc, log: add backgroundvalidation to getblockchaininfo (Pol Espinasa)5b2e4c4a88log: update progress calculations for background validation (Pol Espinasa) Pull request description: `getblockchaininfo` returns `verificationprogress=1` and `initialblockdownload=false` even if there's background validation. This PR adds information about background validation to rpc `getblockchaininfo` in a similar way to `validationprogress` does. If assume utxo was used the output of a "sync" node performing background validation: ``` $ ./build/bin/bitcoin-cli getblockchaininfo ... "mediantime": 1756933740, "verificationprogress": 1, "initialblockdownload": false, "backgroundvalidation": { "snapshotheight": 880000, "blocks": 527589, "bestblockhash": "0000000000000000002326308420fa5ccd28a9155217f4d1896ab443d84148fa", "mediantime": 1529076654, "chainwork": "0000000000000000000000000000000000000000020c92fab9e5e1d8ed2d8dbc", "verificationprogress": 0.2815790617966284 }, "chainwork": "0000000000000000000000000000000000000000df97866c410b0302954919d2", "size_on_disk": 61198817285, ... ``` If assume utxo was not used the progress is hidden: ``` $ ./build/bin/bitcoin-cli getblockchaininfo ... "mediantime": 1756245700, "verificationprogress": 1, "initialblockdownload": false, "chainwork": "00000000000000000000000000000000000000000000000000000656d6bb052b", "size_on_disk": 3964972194, ... ``` The PR also updates the way we estimate the verification progress returning a 100% on the snapshot block and not on the tip as we will stop doing background validation when reaching it.

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.
