Think of blockchain as a chain of digital “blocks,” each containing a batch of transaction data. Each block is time-stamped, encrypted, and linked to the previous one, forming an unalterable record. Here’s the nuts and bolts:
Decentralization
Instead of a single authority (like a bank or port operator) controlling the data, it’s stored across thousands of computers (nodes). Everyone has the same version of the truth, reducing fraud and errors.
Immutability
Once data is added—say, a shipment’s departure time—it’s locked in with cryptographic hashes. Changing it would require altering every subsequent block across the network, which is nearly impossible.
Transparency
Authorized parties (shippers, carriers, customs) can access the ledger in real-time, seeing exactly where goods are without relying on slow, error-prone paperwork.
Smart Contracts
These are self-executing agreements coded into the blockchain. For example, a smart contract could automatically release payment to a trucking company once a shipment is delivered, cutting out delays and disputes.
