b2aa9e8528Add release note for MIN_STANDARD_TX_NONWITNESS_SIZE relaxation (Greg Sanders)8c5b3646b5Relax MIN_STANDARD_TX_NONWITNESS_SIZE to 65 non-witness bytes (Greg Sanders) Pull request description: Since the original fix was set to be a "reasonable" transaction to reduce allocations and the true motivation later revealed, it makes sense to relax this check to something more principled. There are more exotic transaction patterns that could take advantage of a relaxed requirement, such as 1 input, 1 output OP_RETURN to burn a utxo to fees for CPFP purposes when change isn't practical. Two changes could be accomplished: 1) Anything not 64 bytes could be allowed 2) Anything above 64 bytes could be allowed In the Great Consensus Cleanup, suggestion (2) was proposed as a consensus change, and is the simpler of the two suggestions. It would not allow an "empty" OP_RETURN but would reduce the required padding from 22 bytes to 5. The functional test is also modified to test the actual case we care about: 64 bytes Related mailing list discussions here: https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2022-October/020995.html And a couple years earlier: https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2020-May/017883.html ACKs for top commit: achow101: reACKb2aa9e8528glozow: reACKb2aa9e8528pablomartin4btc: re-ACKb2aa9e8528jonatack: ACKb2aa9e8528with some suggestions Tree-SHA512: c1ec1af9ddcf31b2272209a4f1ee0c5607399f8172e5a1dfd4604cf98bfb933810dd9369a5917ad122add003327c9fcf6ee26995de3aca41d5c42dba527991ad
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.
