Just To Save You The Hassle Of Reading Vice Or Buzzfeed...
THE OLDEST BLOCKCHAIN WAS PRINTED IN THE NEW YORK TIMES!!!!!!!
That's the clickbait headline that's going around a couple of the garbage sites like Vice and Buzzfeed. To prevent you from having to read them, I've found an alternate source for you, free of charge: Finding The Oldest Blockchain.
If you don't know what blockchain is, then you'll want to start by reading my Explain-Like-I'm-Five-Years-Old piece on hashes. It was written for people with an interest in Bitcoin. I suspect that interest in Bitcoin has greatly waned since I wrote it; judging by the current market cap, it's a third of what it is now. Which reminds me. I have a Bitcoin story of my own to tell. Watch this space.
