4101ec9d2e05a35c35f587a28f1feee6cebcc61b doc: mention that we enforce port=0 in I2P (Vasil Dimov) e0a2b390c144e123e2fc8a289fdff36815476964 addrman: reset I2P ports to 0 when loading from disk (Vasil Dimov) 41cda9d075ebcab1dbb950160ebe9d0ba7b5745e test: ensure I2P ports are handled as expected (Vasil Dimov) 4f432bd738c420512a86a51ab3e00323f396b89e net: do not connect to I2P hosts on port!=0 (Vasil Dimov) 1f096f091ebd88efb18154b8894a38122c39624f net: distinguish default port per network (Vasil Dimov) aeac3bce3ead1f24ca782079ef0defa86fd8cb98 net: change I2P seeds' ports to 0 (Vasil Dimov) 38f900290cc3a839e99bef13474d35e1c02e6b0d net: change assumed I2P port to 0 (Vasil Dimov) Pull request description: _This is an alternative to https://github.com/bitcoin/bitcoin/pull/21514, inspired by https://github.com/bitcoin/bitcoin/pull/21514#issuecomment-815049933. They are mutually exclusive. Just one of them should be merged._ Change assumed ports for I2P to 0 (instead of the default 8333) as this is closer to what actually happens underneath with SAM 3.1 (https://github.com/bitcoin/bitcoin/pull/21514#issuecomment-812632520, https://github.com/bitcoin/bitcoin/pull/21514#issuecomment-816564719). Don't connect to I2P peers with advertised port != 0 (we don't specify a port to our SAM 3.1 proxy and it always connects to port = 0). Note, this change: * Keeps I2P addresses with port != 0 in addrman and relays them to others via P2P gossip. There may be non-bitcoin-core-22.0 peers using SAM 3.2 and for them such addresses may be useful. * Silently refuses to connect to I2P hosts with port != 0. This is ok for automatically chosen peers from addrman. Not so ok for peers provided via `-addnode` or `-connect` - a user who specifies `foo.b32.i2p:1234` (non zero port) may wonder why "nothing is happening".

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.
