The security of the blockchain depends on it. As my learnings went from Bitcoin to Blockchains to Distributed Ledgers, I made a faulty extrapolation. I did not […]

I had some thoughts: Thought one: if anything can undo the blockchain immutability, quantum computing is the one thing to worry about. Bye Bye Immutability! […]

I am going to assume whoever is reading this has no idea what hashes are, which gives me freedom to explain it my way. […]
