Blockchain described in one sentence: A blockchain is really a kind of database that’s shared across loads of different computers that are each running the same software; each bit of data is secured using some complicated bits of cryptography that means that only people that are meant to be adding to or editing the data can do that job. WIRED Magazine, 2018 Recently, I had a job interview with a company that builds their business model on providing add-on services for their customers’ databases built upon the open source centralized DB platform known as PostgreSQL. Probably the reason why I was considered to do digital copywriting for them is my previous experience writing for tech companies like PTC, Satcon, and L-1 to name a few. For PTC, I did a ton of writing for their PLM Product Marketing Group. PLM (i.e. product lifecycle management) is a massive technology platform and manufacturing methodology that relies heavily on data-driven digital thread content, product data management, and databases to name a few. So as you can see, I know a thing or two about databases. Also, I have written about Blockchain Technology (or BlockTech as I will be using this portmanteau from now on) in the past; therefore, I am well aware of the hot new trends for this distributed cutting-edge decentralized data-repository/processing platform. During the interview, I asked a simple question: How is your approach to utilizing a centralized DB value-add over the hot new decentralized DB technology trend known as Blockchain? Digital Batman’s Alter Ego, Nick, 2021 Needless to say, the developer that I was interviewing with did not really like the question all that much. His answer was more defensive rather than enlightening: “…centralized DBs are not going away anytime soon, so people need to understand that Blockchain is more like a curiosity right...

October 14, 2019Today’s Digital Tech & Industry section is all about the cornerstone of our civilization: cash! That’s right. For as long as there’s been human society there has been some form of currency. For most of human history it’s been more or less little bits of embossed metal called coins. However, in the 21st Century (thank goodness) we have Digital Mobile Payments, Cryptocurrencies, and Social Media Payments to enable all of our commercial indulgences! Hard to believe that there would be more than one way to pay but there it is. When we look back at 20th Century digital payments, the only examples that come to mind are wire transfers and direct deposit. However, now those seem so quiant compared to what we have going on today. A lot of hullabaloo is made over cryptocurrencies such as Bitcoin and others (e.g. NEO, EOS, and Monero); however, in a practical sense, trying to pay for say a pair of jeans or a latte with them still seems a bit too farfetched. But for millennials and Gen‐X/Yers, it’s as simple as taking out their smartphone (or raising their smartwatch) and tapping the POS (Point of Sale) terminal using their eWallets (i.e. Apple/Google/Samsung Pay). Apple Pay, Google Pay, and Samsung Pay are all pretty much the same with only a few device‐specific differences. They all use the NFC (or Near‐Field Communication) chips inside them to enable “contactless” transactions that are funded by a person’s digital wallet (or eWallet) usually linked to a bank/credit account. Samsung Pay actually has another level of mobile payment called MST (Magnetic Secure Transaction) that enables users to use their phones just like swiping a credit card—good for older POS terminals that do not have an NFC chip reader. And this is all well and good for millions of transactions...
