How does proof-of-work prevent 51% attacks? Can the attacker change the whole chain in a 51% attack? How often has a 51% attack occurred? Could a government agency reverse a transaction? Did Satoshi foresee ASICs and how competitive mining would be? Does China control Bitcoin mining? Should we change the proof-of-work to solve this?

These questions are from the second, third, and fourth sessions of MOOC 11, which took place on February 7th, February 14th, and February 22nd 2019 respectively.

  1. I'm fascinated with monero's randomx. It's hard to describe how seductive the early public Bitcoin clients were.

    The awe of it. The incredible feeling of power and self-worth. Emanating from a true sense of autonomy, liberty, personal sovereignty and impending justice.

    Bitcoin had everything I needed. Sitting on my desktop. Accessible to almost everyone. And by extension, making everyone accessible to me. Because commerce is and integral part of human nature.

    My own personal sovereign economic ecosystem. Based on informed collective self interest and market principles.

    An economy for everyone. Not just a lucky few. Devoid of special-interest politics and crony capitalism. Aka Usury.

    Randomx might not be right for Bitcoin. But it seems right for Monero. I would like to see Monero take randomx to the next level. By tuning it's protocol to advantage smartphone ARM CPUs and architecture.

    Doing so would further decentralize the network. By advancing the Independence and autonomous sovereignty of individual users and owners of Monero..?

  2. And what's the edge miners will need in the future now that ASICs are leveling out? It'll be finding cheaper and cheaper electricity, i.e. excess electricity or renewables. You won't find Bitcoins critics headlining that.

    Thanks again for another great video Andreas.

  3. Actually if all miners decide to rebuild 100 blocks they could get a double reward in the measure that they already have spent all reward from the old chain. Actually who lose is the one that have those bitcoin on their wallet at the time of the blockchain reorganization…

    For this reason, theoretically, recently mined bitcoin should be less valuable than older ones.
