What you freaks are looking at is an excerpt from an impressively concise blog post that was published in January 2018 that I highly recommend you freaks check out if you have the time at some point today or over the weekend. This is a great follow up read to last Friday's issue, in which we learned that Satoshi initially referred to Bitcoin as a timechain and never mentioned the word blockchain. That wretched 'B' word was contrived by some marketer in the early days and has stuck around like an unwanted stench for the better part of a decade.
Though the author of this very lucid post, Grisha Trubetskoy, does not dive into the semantics of whether or not timechain or blockchain is a better descriptor for this distributed system. Instead, he focuses on explaining how Bitcoin is an ordering system, how the concept of time should be understood, how Proof of Work is simply a mechanism to prove what happened when, and how the participation in Bitcoin's Proof of Work is universal.
Do yourselves a favor and tear through this ASAP. Though, I wouldn't fault you for saving it for tomorrow morning to enjoy over a cup of coffee.
Dentists appointments, boo.
Enjoy your weekend, freaks.
