OBJECTIVE
Blockchain and transactions
A blockchain is a shared record. A transaction is a signed instruction that changes that record, for example moving an asset from one address to another.
LEARNING VISUAL
Learning diagram: Blockchain and transactions
Concrete example
If a block explorer shows 1 token moving from address A to address B, you can verify the transfer. You cannot infer who owns A or B without separate evidence.
Practical checklist
- Identify the chain
- Verify the transaction hash
- Separate observed facts from assumptions
