Can someone tell me step by step approach to explore Monero Blockchain in Ubuntu? From the beginning. Is there any way explore it with the terminal to see inside each block? Like what is the index of a block, transactions, previous hash, current hash etc.
Usually you explore the blockchain with a browser. There are different blockchain explorers for Monero. For example:
It's pretty straight forward. You will see the block (also called 'height'), the timestamp (the block got generated), the size of that block, the number of transactions that are part of that block and the hash. You will see that for every block.
If you click on one of the rows (every row is a block) you will see the content of the block (transactions that are part of that block).
Every transaction has a hash and an amount that is usually not disclosed
