*Unraveling the difference between Blockchain and Smart Contracts: Joe Breaks it Down for Esi.*
*Esi:* Hey Joe, I'm interested in understanding the difference between Blockchain and Smart Contracts.
*Joe:* Sure, They are both related to each other, but they serve different purposes.
*Esi:* So, what exactly is Blockchain?
*Joe:* Blockchain is a distributed and decentralized ledger technology. It's like a chain of blocks where each block contains a list of transactions. The unique thing about Blockchain is that once a block is added, it cannot be easily altered or deleted. It's transparent and secure because each block's data is linked to the previous block through a cryptographic hash.
*Esi:* I see. So, it's a secure way of recording transactions and data. But how does it relate to Smart Contracts?
