Private Blockchain Technology – essential for Trust

The foremost challenge in the present world is trust. Addressing the protection of sensitive personal information in the opaque world of Information Technology – hidden behind acronyms and jargon and supported by statements promising “best efforts” – can be extremely difficult with considerable challenges. In addition, consumer demands are also changing constantly. Consumers want affordable and immediately accessible products, typically online, albeit with no compromise on factors such as authenticity, validity, and above all protection of personal information. Blockchain technology can provide crucial support for addressing these factors – most notable being the highest level of protection of sensitive personal information.

Although Blockchain technology has come to the fore through the most famous Public Blockchain – Bitcoin – it is Private Blockchain Technology that offers the supreme levels of privacy and information security that is essential for any enterprise that deal with a lot of sensitive information.


Private Blockchain Vs Database: What’s The Difference?

Due to the feature of having a distributed ledger, many think private blockchains and databases function as the same. However, these two technologies are completely different.

After the emergence of blockchain technology, there have been many curiosities as to what the technology really offers. Even though many people think that blockchain is just one type, there are other variations for different purposes. However, confusion with private blockchain vs database is still ongoing among tech enthusiasts. Without going into the architectural and technical details, the key features are summarised as:

Data Handling – Immutability

Data handling is by far one of the top differences between Private Blockchain Vs Database. In a private blockchain, users are only allowed to read and write and nothing else. So, once data is entered into the ledger, it cannot be altered in any way.

This is known as immutability, and blockchain maintains it at any cost. It is the essential feature of any blockchain technology.

On the other hand, in an orthodox database, users can write, read, delete, or update an entry after the initial data entry event. It follows CRUD protocol (create, read, update, delete). So, data can be manipulated, altered, or deleted if you have access to the database.

So, in instances where data immutability and integrity are paramount – the private blockchain is immensely superior and desirable to the orthodox database.

Private Blockchain Vs Public Blockchain: What’s The Difference?

By using our own proprietary private blockchain – the only people with access to your data are you and Worker Checks. We do not utilise a public blockchain and as such no unauthorised 3rd party has access to our system and your personal data.

The primary difference between public and private blockchain is that the public blockchains may be joined by everyone, while private blockchains may only be joined by authorised users. While start-ups seem to focus on leveraging the trust less concept of a public blockchain to create innovations, enterprises more often use a private blockchain to build multi-party business applications with high scalability within a trusted environment.

Private blockchains are often referred to as ‘permissioned’ blockchains. Unlike public blockchains, where anyone can download the software, form a node, view the ledger and interact with the blockchain, private blockchains are run and operated by an entity – in this case we at Worker Checks (Block Chain Mate’s subsidiary putting private blockchains into real world business) build and operate our own private blockchain.

In fact when developing the technology we were nominated for prestigious international awards by Lloyds of London.

As Worker Checks (Block Chain Mate’s subsidiary putting private blockchains into real world business) is in charge of the running our private blockchain we control who can access the private blockchain and may also control the type of access rights each participant has. For example, some participants may be restricted to viewing (some or all of) the data on the ledger, whereas others may also have permission to submit new transactions for recording on the blockchain.

So, an individual can view their certificate(s) and personal data directly off the blockchain with permissioned access. Or  a 3rd party (e.g. employer) views your certificate using our authentication feature – they view the data / certificate directly off the blockchain- as the data is immutable – you can be assured that data has not been tampered with an is impossible to change.
