Technology has provided businesses various methods to expand and blockchain is an example. Blockchain is a common term, however, when we hear the term blockchain what we think about is a cryptocurrency like Bitcoin, Ethereum, and the rest.
Blockchain is much more than that and can be implemented in different applications like the Internet of Things, energy, healthcare, business, etc.
Blockchain aims to change the course of marketing and advertising. How? What is the connection between blockchain and business marketing, and how can it be used as a tool for digital marketing?
This is what we’ll be discussing in this article, but first,
What is Blockchain?
In more technical terms, blockchain is a distributed and immutable ledger with growing lists of records (blocks) linked securely via cryptographic hashes. It is a digital diary that records transactions across many computers.
Let’s think of a group of friends making a bet on a football game. Depending on the team they support everyone has to pay a certain amount, and if a football team wins, the group supporting the winning team gets all the money contributed.
In this situation, everyone has a record of the bet, so when a football team wins they’re all aware of how much the group in support gets- this is not entirely how blockchain works, but, it gives an example of how transparent transactions are in a blockchain.
All the nodes running in a blockchain network have a record of every transaction that has ever occurred which is why it is termed a distributed system. In a distributed system, everyone keeps a record maintaining consistency, and if the record is updated, everyone is updated with that change.
The nature of blockchain is also immutable meaning it cannot be tampered with or manipulated easily. To expand on the immutability of blockchain, let’s consider these key pieces, such as;
Transactions: Transactions that took place when a block was created.
Hash: A digital fingerprint (unique alphanumeric sequence) representing transactions on a block. Also, changes made to a block change the hash as well.
Let’s assume we create a record and add it to a blockchain. When we add a new record, it is chained to a previous record, as we add more records, they become linked hence the name “blockchain”.
When a new block is created, it’ll have its set of transactions, the hash of the previous block including its hash, and every block added to the chain adheres to the same pattern.
If a change were to be made to one of the records or blocks in a chain it means that the hash would change- therefore, the block that has its hash recorded would become incorrect meaning that you’ll have to tamper with every block on the chain to make changes which would be reflected, making it hard to modify.
There are different types of blockchain technology e.g. public, private, hybrid, permissioned, and permissionless, and each has its benefits and limitations, which we’ll cover in another article.
