c6e2c31c55rpc: unhide waitfor{block,newblock,blockheight} (Sjors Provoost)0786b7509arpc: add optional blockhash to waitfornewblock (Sjors Provoost) Pull request description: The `waitfornewblock` is inherently racy as the tip may have changed since the last RPC call, and can even change during initial processing of this call. Add an optional `blockhash` argument so the caller can specify their current tip. Return immediately if our tip is different. I've made it fail if `LookupBlockIndex` fails. This should never happen if the user got the block hash from our RPC in the first place. Finally, the `waitfor{block,newblock,blockheight}` RPC methods are no longer hidden in `help`: - the changes in #30409 ensured these methods _could_ work in the GUI - #31785 removed the guards that prevented GUI users from using them - this PR makes `waitfornewblock` reliable So there's no more reason to hide them.

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.
