b19caeea098f92a7f72aaeee49573358f4b153a3 doc: add release note for #31560 (named pipe support for `dumptxoutset` RPC) (Sebastian Falbesoner) 61a5460d0d6cd174d395c51333def798fe7442fe test: add test for utxo-to-sqlite conversion using named pipe (Sebastian Falbesoner) 2e8072edbeb20a8c05c0dbd06ca105bc4dd07b96 rpc: support writing UTXO set dump (`dumptxoutset`) to a named pipe (Sebastian Falbesoner) Pull request description: This PR slightly modifies the `dumptxoutset` RPC to allow writing the UTXO set dump into a [named pipe](https://askubuntu.com/a/449192), so that the output data can be consumed by another process, see #31373. Taking use of this with the utxo-to-sqlite.py tool (introduced in #27432), creating an UTXO set in SQLite3 format is possible on the fly. E.g. for signet: ``` $ mkfifo /tmp/utxo_fifo && ./build/bin/bitcoin-cli -signet dumptxoutset /tmp/utxo_fifo latest & $ ./contrib/utxo-tools/utxo_to_sqlite.py /tmp/utxo_fifo ./utxo.sqlite UTXO Snapshot for Signet at block hash 000000012711f0a4e741be4a22792982..., contains 61848352 coins 1048576 coins converted [1.70%], 2.800s passed since start .... .... 60817408 coins converted [98.33%], 159.598s passed since start { "coins_written": 61848352, "base_hash": "000000012711f0a4e741be4a22792982370f51326db20fca955c7d45da97f768", "base_height": 294305, "path": "/tmp/utxo_fifo", "txoutset_hash": "34ae7fe7af33f58d4b83e00ecfc3b9605d927f154e7a94401226922f8e3f534e", "nchaintx": 28760852 } TOTAL: 61848352 coins written to ./utxo.sqlite, snapshot height is 294305. ``` Note that the `dumptxoutset` RPC calculates an UTXO set hash as a first step before any data is emitted, so especially on mainnet it takes quite a while until the conversion starts and something is happening visibly.

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.
