How does blockchain work?
Blockchains are a list, or rather ‘chain’, of blocks linked up through cryptography. Each block features encrypted transaction data and it can’t be modified. This means that two parties can transact in a secure way, with no need for further verification. It signals an entirely new way to trust.
Is Tokenisation the big blockchain app?
Up until now, Blockchain has been used as the basis behind encrypted digital currencies (cryptocurrency), and many other use-cases have been considered without really taking off yet.
Discovering Digital Identities
Having a Digital Identity may sound like an abstract idea but being able to correctly identify which online device we are interacting with is a cornerstone in the online world. The number of connected devices is steadily increasing, forecast to reach about 18 billion in 2022, and the issuing and management of Digital Identities for those devices is a fundamental part of the security and automation for these devices.
To illustrate the potential of blockchain, consider that the automation of devices also includes automatic management of money. Here’s a great example: a self-driving car, as part of a taxi service, realises and registers that it needs to be cleaned. It can automatically drive to a car wash, pay for the service, and be back on the road ready to serve customers without any human having to manage the process.
The blockchain is a perfect fit for Digital Identities because it allows many different issuers to coexist and interoperate in a transparent, secure, and device-friendly fashion.
In a recent Ericsson Technology Review article, my colleagues and I explore the benefits of blockchain technology to facilitate online trust, as well as presenting key telecom use cases.
