fa2797808e test: Remove python3.4 workaround in feature_dbcrash (MarcoFalke) dddd1d05d3 .python-version: Specify full version 3.5.6 (MarcoFalke) faa7cdf764 scripted-diff: Update copyright in ./test (MarcoFalke) fa0e65b772 scripted-diff: test: Remove brackets after assert (MarcoFalke) fab5a1e0f4 build: Require python 3.5 (MarcoFalke) fa6bf21f5e scripted-diff: test: Use py3.5 bytes::hex() method (MarcoFalke) Pull request description: Python 3.4 is EOL after March 2019, so switch to 3.5. See https://devguide.python.org/#status-of-python-branches This pull does the following in a bunch of commits: * scripted diff to use the `bytes::hex()` method in place of previous wrappers (`b2x`, `bytes_to_hex_str`, `hexlify`, ...) * Update the build system (gitian and travis) to remove python2.7 and replace it with python3.5 * Another scripted-diff to remove brackets after `assert`. This is unrelated to the python3.5 switch, but a stylistic commit, so probably not worth to split up. The motivation behind it is to avoid asserting on data structures (such as tuples of length one), which never fails: ```py >>> assert(False,) # with brackets >>> assert False, # without brackets SyntaxError: invalid syntax >>> assert False # proper assertion AssertionError ``` * And then a final scripted diff to update the copyright headers in the `test` subfolder, since I touched most of the files anyway and it wouldn't make sense to split this commit out into a separate pull.

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.
