# Two ways to install Bitcoin Core:
1. Compile from source
2. Install the pre-compiled binary


# Compile from source (Debian Based)

1. Install build dependencies:
```
sudo apt-get install \
build-essential \
libtool \
autotools-dev \
automake \
pkg-config \
bsdmainutils \
python3 \
libevent-dev \
libboost-dev \
libsqlite3-dev
```

2. Install GUI dependencies:
```
sudo apt-get install \
libqt5gui5 \
libqt5core5a \
libqt5dbus5 \
qttools5-dev \
qttools5-dev-tools \
qtwayland5 \
libqrencode-dev
```

3. Download the source:
```
git clone https://github.com/bitcoin/bitcoin
```


4. Checkout a release. At time of writing, the
latest is v26.0:
```
git tag -n | sort -V

git checkout v26.0
```


5. Compile:
```
./autogen.sh

./configure --disable-wallet

make -j "$(($(nproc) + 1))"
```


7. Configure `~/.bitcoin/bitcoind.conf`:
```
# accept RPCs
server=1

rpcuser=foo
rpcpassword=bar

# allowed IPs
rpcbind=0.0.0.0
rpcallowip=192.168.1.0/24

# index transactions
txindex=1

# only peer over Tor:
#proxy=127.0.0.1:9050
#listen=1
#bind=127.0.0.1
```


8. Create, enable and start the systemd service:
```
[Unit]
Description=Bitcoin Core Daemon
After=network-online.target

[Service]
User=schwab
Type=simple
Restart=on-failure
ExecStart=/usr/local/bin/bitcoind

[Install]
WantedBy=multi-user.target
```

```
sudo systemctl enable bitcoind.service
sudo systemctl start bitcoind.service
```


6. Run bitcoind:
```
./src/bitcoind
```

7. Or bitcoin-qt:
```
./src/qt/bitcoin-qt
```



# Install the pre-compiled binary

1. Import Core Maintainers PGP keys:
```
git clone https://github.com/bitcoin-core/guix.sigs

gpg --import guix.sigs/builder-keys/*
```

2. Download the Bitcoin Core binary:
```
wget https://bitcoincore.org/bin/bitcoin-core-26.0/bitcoin-26.0-x86_64-linux-gnu.tar.gz
```

3. Download the SHA256 checksums and their signatures:
```
wget https://bitcoincore.org/bin/bitcoin-core-26.0/SHA256SUMS
wget https://bitcoincore.org/bin/bitcoin-core-26.0/SHA256SUMS.asc
```

4. Verify checksum of the release file:
```
sha256sum --ignore-missing --check SHA256SUMS

bitcoin-26.0-x86_64-linux-gnu.tar.gz: OK
```

5. Extract the binary:
```
tar xzf bitcoin-26.0-x86_64-linux-gnu.tar.gz
```

6. Install the binary:
```
sudo install -m 0755 -o root -g root -t /usr/local/bin bitcoin-26.0/bin/*
```

7. Configure `~/.bitcoin/bitcoind.conf`:
```
# accept RPCs
server=1

rpcuser=foo
rpcpassword=bar

# allowed IPs
rpcbind=0.0.0.0
rpcallowip=192.168.1.0/24

# index transactions
txindex=1

# only peer over Tor:
#proxy=127.0.0.1:9050
#listen=1
#bind=127.0.0.1
```

8. Create, enable and start the systemd service:
```
[Unit]
Description=Bitcoin Core Daemon
After=network-online.target

[Service]
User=<user>
Type=simple
Restart=on-failure
ExecStart=/usr/local/bin/bitcoind

[Install]
WantedBy=multi-user.target
```

```
sudo systemctl enable bitcoind.service
sudo systemctl start bitcoind.service
