ZeroToBlock — Blockchain Mastery

What it does

ZeroToBlock turns blockchain theory into hands-on simulations. Instead of passive videos or static articles, users explore Proof of Work, hashing, nonce discovery, mining difficulty, Merkle trees, and block validation visually and interactively. Built for engineers, developers, and curious minds who want to understand Bitcoin from first principles. No hype. No abstraction. Just protocol-level clarity.

Learn blockchain, Bitcoin and Proof of Work with interactive courses, mining simulations, SHA-256 demos, Merkle tree explainers and hands-on Bitcoin protocol lessons.

Learn blockchain from first principles with interactive Bitcoin courses, mining simulations, SHA-256 demos, consensus lessons and protocol-level explanations designed for developers, engineers and serious self-learners. Try to find a hash starting with "0000". This is how Bitcoin secures its network. ZeroToBlock turns Bitcoin and blockchain concepts into manipulable systems you can inspect, break and verify instead of memorizing surface-level explanations. Hash inputs, inspect block headers, trace Merkle roots and watch how individual rules shape the Bitcoin system. Simulate Proof of Work, compare valid and invalid blocks, and watch reorganizations, mempool selection and confirmations…from zerotoblock.com

  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.
