How to find out how big the Monero blockchain is?

Question

Is there any way we can find out how big the Monero blockchain download size is today? I see old threads dated 2018 which say it's around 50gb, but there must be a URL somewhere we can found out the current size of the blockchain if we wanted to download for setting up a new node.

Thanks in advance for any help.

Answer 1

You can call a daemons RPC get_info method which will tell you the blockchain database size (in bytes) in the responses database_size field.

And you can find a public node on sites like https://moneroworld.com/.

For example:

curl -d '{"jsonrpc":"2.0","id":"0","method":"get_info"}' \
  http://node.moneroworld.com:18089/json_rpc

Response (truncated):

{
  "id": "0",
  "jsonrpc": "2.0",
  "result": {
    ...
    "database_size": 85899345920,
    ...
  }
}

Which you then convert the bytes to GB however you prefer. The above shows roughly 85 GB. Note this is not the exact size of the blockchain, rather the current size of the database on the node queried.

Answer 2

GetBlkSize.sh

echo "" > /tmp/j
curl -s https://monero.fail/ | grep "<td>https" | sed -r 's/.*<td>(https.*)<\/td>.*/\1/g' | while read -r line ; do
    ./knockknock.sh $line &
done
wait
exit 0

knockknock.sh

    x=$(curl -sd '{"jsonrpc":"2.0","id":"0","method":"get_info"}' $1/json_rpc | grep 'database_size' |  sed -r 's/.*: ([0-9]*)\,.*/\1/g');
    y=$((x/1024/1024/1024));
    if [ "0" -ne "$y" ]; then
        echo -e "\t$y GB block chain at $1" >> /tmp/j 
    fi
    exit 0

then cat /tmp/j

Basically this script looks for the secure monero blockchains. Some are compressed and some are not. So you will see something like this:

$ cat /tmp/j
