3. Blockchain Databases
• Contains two kinds of records.
1. Blocks
2. Transactions
• Blocks hold batches of valid transactions
that are hashed and encoded into
a Merkle tree.
• Each block holds the hash of prior block.
• Data stored on blockchain is generally
considered incorruptible.
• Smart Contracts

4. Smart Contracts
A smart contract is a program which execution is
autonomous and totally transparent.
This execution cannot be reverted and its trace is
public & immutable.
