Blockchain-Based Timestamping: The Complete Guide for Beginners

The technology created in 2008 under the alias Satoshi Nakamoto as an open-source software platform is now poised to revolutionise industries globally.

Here we look at the basics behind blockchain and how its timestamping protocols can benefit a wide range of use cases.

Blockchain technology allows for secure and verifiable transactions without the need for a central authority, such as banks. It maintains a continuously growing list of data records that are linked and secured using cryptography. These blocks can be viewed as public financial ledgers and form a blockchain when linked together in sequence. 

Blockchain-based timestamping improves the security of digital timestamping, as it generates timestamps for data, which are then stored in the blockchain. This innovation enhances the security of digital timestamping by generating timestamps for data and securing them on a decentralized network instead of just storing them on a simple computer server.

What is Blockchain-based Timestamping?

Blockchain-based Timestamping is the process of recording data on a blockchain to prove that it existed at a specific date and time.

Blockchain-based Timestamping services are an innovative way for businesses to provide proof of existence for their documents. It is also used by organizations for tracking legal contracts, patents, and other vital records.

A timestamp record is a digital signature of the sender or receiver on a document, which can be verified against public key infrastructure (PKI).

How Does Blockchain-Based Timestamping Work?

Blockchain-based timestamping is a system to verify data and assign a time or date of creation for digital documents or events.

In the simplest form, the timestamp is a string of characters that uniquely identifies the document or event and indicates when it was created.

Blockchains are decentralized systems that record data in blocks on a ledger. The blocks contain information on transactions between users on the blockchain platform. Each block must have a unique identifier. The hash function provides this identifier by converting an input value to an output value with a fixed number of digits or bits.

What are the Benefits of Blockchain-based Timestamping?

Blockchain-based timestamps have several key benefits;

  • They are more reliable and secure, as they cannot be changed or removed once published to the ledger. 
  • Blockchain is decentralized, which minimizes the possibility of tampering by any one party. 
  • Timestamps can be viewed entirely transparently if desired.

An easy way to compare traditional timestamping to blockchain-based timestamping is to look at the example of a manufacturing company. Ordinarily, a manufacturing company tracks the different steps in the manufacturing process on their own centralized servers. Here data can be lost, corrupted or manipulated, potentially leading to mistrust in the timestamps. On the other hand, with its decentralized, distributed networks, blockchain secures encrypted data at the source in a way that can't be altered. With secure, immutable, transparent data comes trust, and that is where the ultimate benefit lies. 

Practical Applications of Blockchain-Based Timestamping in Everyday Life

As we discussed, blockchain is the world's most promising time stamping system. It stores transaction records in blocks, which are linked together to form a chain of data. Consensus protocols are used to maintain consensus on the blockchain, meaning that every individual on the network knows about every event that has ever taken place. Pretty impressive! But what are some practical applications of this technology?

We identified several key markets where blockchain technology can have the most significant impact.

  1. Logistics & supply chain

The supply chain is full of important events, and consumers are increasingly interested in where products come from and how they're made. Blockchain-based timestamps can be used within supply chains to improve transparency, accuracy and accountability.

  1. Insurance

Fraud has a major impact on the insurance industry, with opportunistic fraudsters and criminal enterprises costing the industry vast sums of money. Blockchain timestamping can help eliminate fraud by securing data at the source and providing an indisputable record of claim events, such as property damage or car crashes.

  1. Intellectual property & copyright

Blockchain timestamps provide an immutable history that can't be doubted. When it comes to IP and copyright, having irrefutable evidence of when you created your work is critical in the case of infringement.

  1. Legal & law 

The legal and law industries rely on the security of sensitive, valuable data. Whether it is a notarial certificate or evidence in a court of law, establishing continuity and authenticity is vital. Blockchain technology ensures the provenance of information is secured in a way that can't be tampered with, manipulated or destroyed, solving many issues in the legal system. 

  1. Inspection & facility management

When dealing with complex systems or construction processes, inspections are crucial to providing safety and accountability. Facility Managers can use blockchain-based timestamps to create an immutable record of an inspection being executed the right way.


Blockchain technology has been gaining traction in recent years. It is one of the best ways to secure data, as it is incorruptible, transparent, affordable and scalable. Blockchain-based timestamps are immutable and tamperproof, which make them a good option for archiving data. These features can be used to solve some key challenges that many industries face every day.
