Timestamp
A timestamp is a digital record of a date and time. It records exactly when something happens.
What is a timestamp?
A timestamp can show, for example, when a file was created, a transaction was carried out, or a block was added. A block is a group of data added to a blockchain.
A blockchain is a shared digital record. Timestamps put events in the correct order, creating a verifiable timeline.
A timestamp is often stored as a series of numbers. This number sequence represents a specific moment in time.
An example of a timestamp
Suppose a crypto exchange executes a trade. The timestamp records when the trade took place.
It works in a similar way on a blockchain. A new block is assigned a timestamp, showing which block came first and which was added later.
Why is a timestamp important in crypto?
In crypto, timestamps help record the order of transactions and blocks. This makes it harder to change data after the fact without anyone noticing.
That order also helps prevent double spending. This means someone can’t spend the same cryptocurrency twice.
In news about Bitcoin or mining, timestamps may come up when discussing how quickly blocks are created or the network’s difficulty. A timestamp doesn’t prove that a time is exact, but it is an important tool for checking the network’s timeline.
