What is blockchain?

Blockchain is a distributed ledger technology that allows for secure, transparent, and tamper-proof transactions. In a traditional database system, a central authority (such as a bank or government) controls and updates the ledger. In contrast, blockchain is decentralized, meaning that every participant in the network has a copy of the ledger and can view and verify transactions. The ledger is secured through cryptography and consensus mechanisms, ensuring that it cannot be altered or tampered with without the agreement of the majority of participants.

Blockchain is a reliable distributed ledger

One of the main reasons for blockchain's versatility is its ability to eliminate intermediaries and reduce the risk of fraud and errors. In industries such as finance, supply chain management, and healthcare, where trust is paramount, blockchain can increase transparency and accountability. For example, in the finance industry, blockchain can be used to create a more efficient and secure system for transactions and money transfers. In supply chain management, blockchain can provide a transparent and verifiable record of every step in the production and distribution process, reducing the risk of counterfeit goods and increasing efficiency.

There are also numerous bleeding-edge uses of blockchain that are being explored. One such use is in the area of digital identity. With the rise of online services and e-commerce, the need for a secure and verifiable digital identity is becoming increasingly important. Blockchain can provide a secure and decentralized system for managing digital identity, allowing individuals to control their own data and share it with trusted parties. This could have applications in everything from banking to healthcare to voting.

Another potential use of blockchain is in the area of decentralized finance (DeFi). DeFi is a rapidly growing area of finance that aims to use blockchain technology to create a more open, accessible, and transparent financial system. DeFi applications include decentralized exchanges, lending platforms, and prediction markets, among others. These applications have the potential to disrupt traditional financial systems by providing greater access to financial services, reducing transaction costs, and increasing transparency.

Blockchain is a powerful and versatile technology with numerous applications across a wide range of industries. Its ability to increase transparency, reduce fraud and errors, and eliminate intermediaries makes it an attractive option for industries where trust is paramount. As new uses of blockchain continue to be explored, it is clear that this technology has the potential to revolutionize the way we think about security, trust, and decentralization.

Microsoft CIAM debuts at Build 2023

Image
For a long time we've been aware of Microsoft's efforts towards converging Azure Active Directory B2C and Azure Active Directory. They are making this change in order to provide a single stable product for the back end portal and other aspects of these identity services.  New developments will see a 'CIAM' product sitting on top of AAD - this replaces (or will eventually replace) B2C.   CIAM will also provide better experiences for developers hoping to build user journeys (sign in, sign up, etc.). Microsoft continues to support AAD B2C.  At time of writing it provides a fuller feature set.  However, B2C as-is will eventually retire, and migration paths will be important. The CIAM solution will offer more back-end management features, and an event-driven programming paradigm for user journeys. I will make more information available as and when!

LinkedIn now uses Verified ID for Employee verification

Image
  Microsoft Verified ID is a digital identity verification solution that enables individuals to obtain digital "credentials" from organisations that know them, or more accurately, that know some aspect of their identity.  For example, their name, their educational qualifications, or in this case, their employment status.  These credentials can then be shared with third-party organizations, such as employers or educational institutions, in a secure and trusted manner.  LinkedIn, which is owned by Microsoft, has integrated with Microsoft Verified ID to allow LinkedIn members to verify their employment status. Using this new integration, employers can create a custom process for verifying employees, and employees, once they have done this, can present the credential to LinkedIn in order to obtain the new green "check mark" on their LinkedIn profile. Currently this requires the LinkedIn app - at time of writing there is no announcement yet about migrating this feature t

Keeping safe beyond sign-in

Image
As The Register reports today , Microsoft briefly exposed a plethora of passwords and other secrets due to a bulk upload of data to GitHub recently. The data was a set of AI training data - data used to teach AI models how to understand the world around them. It makes no sense having the best locks on your front door if you leave the back door open... so what can we learn from this episode? Protecting passwords and other sensitive information from exposure to the wider world is essential for maintaining your online security. Here are some measures you can take: Use Strong, Unique Passwords: Create strong, complex passwords that are difficult to guess. Use a combination of uppercase and lowercase letters, numbers, and special characters. Avoid common dictionary words or phrases. Ensure your passwords are at least 12-16 characters long. Use a passphrase, which is a sequence of random words or a sentence that's easy to remember but hard to crack. Use a Password Manager: A password man
