Syncing Monero blockchain on multiple machines

• Trying to find fast way to download Monero CLI and sync/download the blockchain to multiple machines
• reference: https://www.monero.how/tutorial-how-to-speed-up-initial-blockchain-sync

Download & extract build:

mkdir monero
cd monero
 ## mac download
curl -J -L https://downloads.getmonero.org/cli/mac64 -o monero.tar.bz2 
## for linux download, use https://downloads.getmonero.org/cli/linux64
tar -vxjf monero.tar.bz2

Option 1 (network sync):

Sync from network, and export blockchain to thumbdrive

cd cli
./monerod # this will take hours...
./monero-blockchain-export # this will export the 25+GB file ~/.bitmonero/export/blockchain.raw

Then on other machines, import blockchain from a local file

./monero-blockchain-import --verify 0 --input-file ./blockchain.raw

Option 2 (download):

• download the blockchain.raw file (~50GB) from a trusted source and import

wget https://downloads.getmonero.org/blockchain.raw
./monero-blockchain-import --verify 0 --input-file ./blockchain.raw

Confirm all is work and then delete the export:

rm blockchain.raw
