Content Proof - Backup & Verify

What it does

Content Proof is a Chrome extension that automatically backs up every tweet you post with cryptographic verification. The moment you tweet, it creates a SHA-256 hash—an immutable mathematical proof of exactly what you posted and when. Everything is stored locally on your device (privacy-first, no servers). If a tweet gets deleted, edited, or disputed, you have undeniable proof it existed. Search your entire tweet history, export verified archives, and generate shareable proof pages.

  I spent 3 years reverse-engineering a 40 yo stock market sim from 1986▲721

  Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986. It has been a rough journey but I finally see the light at the end of the tunnel. I just recently redid the website and thought maybe the full story of how this project came to be would interest you all. Thank you for reading.
