Bitcoin Q&A: Malicious updates and deterministic builds

⭐️⭐️⭐️⭐️⭐️



Could a hacker change the client software of Bitcoin Core to accept fraudulent updates to the consensus rules? Is there a manual update process? What are deterministic builds? Can fraudulent transactions be validated and propagated? Why are there progressive time-outs for nodes that propagate incorrect information? Would miners deliberately propagate invalid blocks? These questions are from the second and third sessions of MOOC 11, which took place on February 7th and February 14th 2019 respectively.
