25dc87e6f84c38c21e109e11f7bbd93f1e1f3183 libconsensus: deprecate (Cory Fields) Pull request description: This library has existed for nearly 10 years with very little known uptake or impact. It has become a maintenance burden. In several cases it dictates our code/library structure (for example necessitating LIBBITCOIN_CRYPTO_BASE), as well as build-system procedures (building multiple copies of object files especially for the lib). Several discussions have arisen wrt migrating it to CMake and it has become difficult to justify adding more complexity for a library that is virtually unused anyway. See for example the discussions: https://github.com/hebasto/bitcoin/pull/41 https://github.com/bitcoin/bitcoin/pull/29123 And here: https://github.com/bitcoin/bitcoin/pull/29180 Where it is pointed out that the libbitcoinconsensus functions are slower than those the internal bitcoind equivalents due to the missing sha2 implementations. Instead, we (fanquake, hebasto, TheCharlatan, and I) propose simply not migrating it to CMake and letting it end with v27. Any remaining use-cases could be handled in the future by libbitcoinkernel. If there are any users currently using libbitcoinconsensus, please chime in with your use-case! Edit: Corrected final release to be v27. ACKs for top commit: TheCharlatan: ACK 25dc87e6f84c38c21e109e11f7bbd93f1e1f3183 fanquake: ACK 25dc87e6f84c38c21e109e11f7bbd93f1e1f3183 - this library has very little, if any impactful real world usage. It has been entirely broken (on various platforms) for long periods of its existence, where nobody even noticed. Pruning this out to save porting, and starting anew with the kernel, is the sane thing to do.

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 a few hundred gigabytes of disk space. Depending on the speed of your computer and network connection, the synchronization process can take anywhere from a few hours to a day 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)
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.
