All operations on the chain are traceable and auditable. Every transaction, every contract interaction, from initiation to completion, is permanently recorded on the blockchain, and anyone can verify it. This is the most unique aspect of blockchain compared to traditional systems—no black boxes, no information asymmetry. If you want to know the historical transactions of a certain address or verify the fund flow of a protocol, you can see it clearly through on-chain data. This verifiability fundamentally changes the way trust is established: no longer relying on a middleman, but directly trusting mathematics and code. Transparency and auditability are the core reasons why the crypto ecosystem can self-purify and attract cautious participants.
