I’ve gotten lazy recently with my writing. My system of breaking down my writing organically into posts, chicken-scratch, and zettels hasn’t worked out how I’d want it to. I ended up producing a lot of draft zettels (little atomic learning notes), and not much else.

Bitcoin: A Peer-to-Peer Electronic Cash System One-Liner Bitcoin is an anonymous digital coin that changes hands based on unique cryptographic keys, validated through a decentralized distributed (P2P) ledger that A) is publicly-run by transaction chronology verification from decentralized volunteer compute nodes that solve a “proof-of-work” (proof of this node’s goodwill) in exchange for the coin itself and B) incentivizes actors with malicious intent to support the system because it is more profitable for them to perform A rather than attack it (antifragile).
