@0xwhatly, my solution was:

  • download file:
aria2c -c -o /chaindata/mainnet-bedrock.tar.zst https://datadirs.optimism.io/mainnet-bedrock.tar.zst > aria2c.log 2>&1 &
  • tar (you need to swap to your own volumes, where you keep the download)
zstd -d /chaindata/mainnet-bedrock.tar.zst -o /chaindata/optimism/torrent_downloads/bedrock.tar
  • then comment out these lines in scripts/init-bedrock.sh
#echo "Fetching download link..."
#BEDROCK_TAR_DOWNLOAD=$(config "bedrock/$NETWORK_NAME/bedrock-download")

#echo "Downloading bedrock.tar..."
#download $BEDROCK_TAR_DOWNLOAD $BEDROCK_TAR_PATH

the whole thing took less than 3h

Great! Sorry @0xwhatly, I noticed the message only when you tagged me.
My link was from the official documentation: https://community.optimism.io/docs/useful-tools/networks/#, and it worked for me 😅
