Block Hash
This Bash script is designed to compare the hash of a specific block from the Heimdall blockchain on your local instance with the hash of the same block obtained from an external API.
#!/bin/bash
latest_block_height=$(curl -s localhost:26657/status | jq -r '.result.sync_info.latest_block_height')
hash_value_local=$(curl -s "localhost:26657/block?height=$latest_block_height" | jq -r '.result.block_meta.block_id.hash')
hash_value_api=$(curl -s "https://heimdall-api.polygon.technology/blocks/$latest_block_height" | jq -r '.block_meta.block_id.hash')
echo "Hash of the block (Local): $hash_value_local"
echo "Hash of the block (API): $hash_value_api"
if [ "$hash_value_local" = "$hash_value_api" ]; then
echo "The hashes are equal."
else
echo "The hashes are different."
