Block to the Future

When most people hear "Blockchain," they think of Bitcoin, bored apes, and volatile stock charts. But as a Manager of Quality and Compliance, when I look at the Blockchain, I don't see money. I see the ultimate Audit Log.


At its core, my job is about establishing the "Single Source of Truth." If a student says they took a course, I need verifiable proof. If a food label says "Organic," you need to trust the certifier. Blockchain eliminates the need for "Trust." It replaces trust with Verification.

The Google Sheet Metaphor

Imagine a shared spreadsheet, like Microsoft Excel or Google Sheets.

  • Centralized (The Bank): The Bank owns the file. They can edit it, delete rows, or freeze your access. You have to trust them.

  • Decentralized (The Blockchain): Imagine a spreadsheet that is duplicated across 10,000 computers instantly.

    • The Rule: You can add a row (a transaction), but you can never delete or edit a row.

    • The Security: To hack it, you wouldn't just need to hack one computer; you would need to hack 5,001 of them simultaneously.

The "Double Spend" Problem

In the digital world, I can copy-paste a document 100 times. If digital money was just a file, I could "copy-paste" my $10 bill and spend it twice. Before Blockchain, we needed a Bank (a middleman) to keep a list and say, "No, Chris already spent that dollar." Blockchain automates that. The code proves the money moved. The Middleman is unnecessary.

Why This Matters (Beyond Bitcoin)

Why should you care if you aren't buying crypto? Because this technology solves the biggest headaches in IT Security and Compliance.

1. The "Integrity" of the CIA Triad In cybersecurity, we adhere to the CIA Triad: Confidentiality, Integrity, and Availability. Standard databases fail at Integrity. If a hacker gains admin access to a server, they can alter the logs to cover their tracks. They can literally delete the history of their crime. On a Blockchain, history is immutable. Once an event is written to the ledger, it cannot be scrubbed. It creates a forensic trail that is mathematically impossible to tamper with. It is the perfect security camera that cannot be turned off or taped over.

2. Supply Chain Verification Right now, you buy "Extra Virgin Olive Oil" and hope it isn't fake (spoiler: 80% of it is). In the future, a Blockchain ledger will track that bottle from the olive tree to your table. You will scan a QR code and see the immutable history of that specific bottle, proving it hasn't been diluted by a middleman.

The Takeaway

Ignore the hype about "going to the moon." Focus on the utility. Blockchain is simply a system where we stop trusting fallible humans and institutions, and start trusting math. And as we know from the scale, the math doesn't lie.

The Dinner Four-mula

Universal Meal Frameworks I have always found traditional recipes a bit stressful. They often feel like rigid scripts that demand very specific ingredients ("1 tsp of fresh tarragon"), and if you don't have that specific item, it feels like you can't make the dish. If you aren't confident with substitutes, you panic, close the cookbook, and order takeout. I've moved away from cooking with strict recipes. Now, I cook with Frameworks . Think of a framework as a flexible blueprint. It allows you to swap out ingredients based on what you have in the fridge without ruining the meal. When I look at a fridge full of random groceries, I don't see "nothing to eat"—I see possibilities waiting to be slotted into a plan. Here are the 4 Universal Meal Frameworks I use to cook 90% of my meals . Framework 1: The "Skillet Smash" (The Keto Answer to Stir-Fries and Pasta) This is my solution for busy nights. It is fast, uses high heat, and relies on a ...

"Are you sitting comfortably? Then I'll begin."

"Hello There"  My name is Chris. I'm 53 as I write this in October of 2025, and I'm a gamer, a golfer, and a guy who's been (and continues to be) on a serious health journey. After losing and then gaining over 190 pounds and facing significant cardiac events, I thought I was doing everything right by following a 'keto' diet. I was wrong. I discovered I was eating 'dirty keto'—my 'health foods' were full of inflammatory oils, hidden starches, and artificial sweeteners that were working against me. 'The Path is Too Deep' is my personal blog about ditching the marketing and discovering the power of a Clean, Anti-Inflammatory, Whole-Food Ketogenic Lifestyle. I'll be sharing what I've learned about reading labels, my ongoing journey with weight loss, my strategies for managing mental health (ADHD/dysthymia), and my thoughts on gaming, golf, and technology. It's my personal rulebook for taking back control. "Not all those...

We're In The Endgame Now

In video games, there is usually a clear "End Game." You defeat the final boss, the loot drops, the credits roll, and you put the controller down. You won. In diet culture, we are sold the same fantasy. We are told that if we just "hit our goal weight" - that magical number on the scale - we have crossed the finish line. We imagine a ticker-tape parade where we are handed a trophy that says "Thin Person," and then we go back to "normal." I am here to tell you, from painful, personal experience: There is no finish line. I have "won" the weight loss game before. I lost 190 pounds . I hit the number. I bought the new wardrobe. And then, slowly, silently, and catastrophically, I gained it all back plus interest. Why? Because I treated my health like a project with a deadline, instead of a business with ongoing operations. I thought I was "done." As I rebuild my body at 53, I am not training for a finish line. I am training for the...
