6d0ea4cf5bdoc: add release notes (Andrew Toth)a2b1c86903txospenderindex: disable bloom filters to optimize disk usage (Andrew Toth) Pull request description: LevelDB bloom filters are only consulted on `Get` point reads. This can be verified in https://github.com/bitcoin/bitcoin/blob/master/src/leveldb/table/table.cc#L224-L228. `InternalGet` is the only place that consults the filter, and it is only reached via a `Get` or `Exists` point read. The filters are never consulted for iterator seeks with an iterator created via `NewIterator`. txospenderindex only reads via iterator seeks, so building them is wasted effort and space. For a db as large as txospenderindex, this results in measurable performance and disk usage. On master, a full sync took 4h37m, and the resulting db was 85.0 GiB. On this branch, a full sync took 3h57m, and the resulting db was 80.9 GiB. So this is a sync speedup of 39 minutes (1.17x), and a disk space reduction of 4.2 GiB.

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.
