echo Install bitcoin-core version $version
#Download bitcoin-core:
wget https://bitcoincore.org/bin/bitcoin-core-$version/bitcoin-$version-x86_64-linux-gnu.tar.gz
#Download the list of cryptographic checksums:
wget https://bitcoincore.org/bin/bitcoin-core-$version/SHA256SUMS
#Download the signatures attesting to validity of the checksums:
wget https://bitcoincore.org/bin/bitcoin-core-$version/SHA256SUMS.asc
#Verify that the checksum of the release file is listed in the checksums file using the following command:
sha256sum --ignore-missing --check SHA256SUMS
#In the output produced by the above command, you can safely ignore any warnings and failures, but you must ensure the output lists "OK" after the name of the release file you downloaded. For example: bitcoin-22.0-x86_64-linux-gnu.tar.gz: OK
#untar
tar -xvf bitcoin-$version-x86_64-linux-gnu.tar.gz
#install
/usr/bin/sudo install -m 0755 -o root -g root -t /usr/local/bin bitcoin-$version/bin/*
