Explaining Blockchain to a Finance Person!

Blockchain is a distributed ledger technology that enables secure, transparent, and tamper-proof transactions. It is a shared database that is maintained by a network of computers. Each computer in the network has a copy of the blockchain, and all the computers agree on what the current state of the blockchain is.


Blockchain is made up of blocks, which are groups of data. Each block contains a timestamp, a link to the previous block, and the data itself. The blocks are linked together in a chain, hence the name "blockchain."

To add new data to the blockchain, a miner must solve a complex mathematical problem. Once the problem is solved, the new block is added to the chain. This process is called mining.



Blockchain is a secure way of storing data because it is decentralized. There is no central authority that controls the blockchain. Instead, the data is stored on the computers of all the nodes in the network. This makes it very difficult to hack or tamper with the data.


Blockchain is also a transparent way of storing data. All the data on the blockchain is public. This means that anyone can view the data, but they cannot change it without solving the mathematical problem.

Blockchain is a powerful technology that has the potential to revolutionize many industries. It is still in its early stages of development, but it has the potential to change the way we store and share data.


Here are some of the potential benefits of blockchain:

  • Increased security: Blockchain is a very secure way of storing data. It is very difficult to hack or tamper with the data on a blockchain.

  • Transparency: All the data on a blockchain is public. This means that anyone can view the data, but they cannot change it without solving the mathematical problem.

  • Efficiency: Blockchain can be used to automate many tasks that are currently done manually. This can save businesses time and money.

  • Trust: Blockchain can be used to create trust between parties who do not know each other. This can be used to facilitate transactions and agreements between parties who would otherwise not be able to trust each other.

Blockchain is a powerful technology with the potential to revolutionise many industries. It is still in its early stages of development, but it has the potential to change the way we store and share data.


Here are some examples of how blockchain is being used today:

  • Finance: Blockchain is being used to develop new financial products and services, such as decentralized exchanges and smart contracts.

  • Healthcare: Blockchain is being used to track patient records and medical supplies.

  • Supply chain management: Blockchain is being used to track the movement of goods and services.

  • Real estate: Blockchain is being used to track the ownership of property.

  • Voting: Blockchain is being used to develop secure and transparent voting systems.

These are just a few examples of how blockchain is being used today. Blockchain is a powerful technology with the potential to revolutionise many industries. It is still in its early stages of development, but it has the potential to change the way we live and work.
