Henceforth vs Examio

Bitcoin you can script. Henceforth is a Bitcoin SV wallet wrapped around a complete FORTH terminal. Send, receive, and broadcast real Bitcoin transactions from a programmable command line. Define your own words, build raw transactions byte by byte, and visualise data with code you write yourself. There's nothing else like it on the App Store. YOUR KEYS, YOUR COINS Private keys live in the iOS Keychain — never on a server. Every send is gated by Face ID or Touch ID. Transactions are permanent on the BSV blockchain, and fees are typically a fraction of a cent. For extra safety, Cold Mode signs transactions on a second offline iPhone over AirDrop — a real air-gap setup without dedicated hardware. A TERMINAL THAT DOES MORE THAN PRINT HELLO WORLD Full Forth-2012 CORE compliance (133 standard words) inside a vocabulary of 384 words, 173 of them Bitcoin Script and Bitcoin SV protocol words, 120 of those opcodes. Print a string: ." Hello, World" Define a word and run it: : square dup * ; 5 square . Pay someone from the command line: 1000 s" 1Q88RPbg..." send The terminal isn't a toy shell — it's the same Forth interpreter that builds the transactions you broadcast. WRITE, SAVE, AND RUN YOUR OWN PROGRAMS Save reusable code as .fs files. The built-in editor and file manager lets you write, version, and rerun scripts. The classic FORTH way: small composable words growing into your own personal vocabulary. CHARTS FROM THE STACK Bar, line, and pie charts from any values on the stack. Visualise sequences, payment histories, or whatever data you compute — directly from FORTH code.
