Keywords/phrases: Risks with centralised custodial exchanges. There are small-scale solutions of online decentralised exchanges (ex. Bisq, formerly Bitsquare) and offline decentralised exchanges (ex. Local Bitcoins). The best way to get bitcoin is to earn it through the expenditure of your labour, which you have now removed from the war machinery of the state.

How do I know that my private key was generated randomly? Could rogue developers of wallet applications access the private keys? Problems with fake wallets. Why is browser hygiene important? How are the private keys of vanity addresses securely generated by pools? These questions are from the third and fourth sessions of MOOC 11, and the March monthly subscriber session, which took place on February 14th, February 22nd, and March 30th 2019, respectively.

At 5:06 pm PST today, my Twitter account (aantonop) was compromised, as part of a broader attack that appears to be an inside job at Twitter. My 2FA was disabled, password changed, sessions logged out and (to add insult to injury) the email associated with @aantonop on Twitter was changed so that Twitter Support won't respond to my requests for support. I am using @aantonop_es, my Spanish language backup Twitter account for now. You can verify that it is mine by watching the video or verifying the PGP signature on this message: https://gist.github.com/aantonop/8306051dd3aab86dec5c94988cb3a066 The PGP key and associated accounts are also listed on https://keybase.io/aantonop ... https://www.youtube.com/watch?v=TMwjPaP8WWs

Zcash and Ethereum as alternatives to Bitcoin. I'm very interested in both, I have used & run nodes for them, and experimented with the testnet. But not as "alternatives," rather as complements to Bitcoin that specialise. My argument has been that Bitcoin and Ethereum do not compete directly. Many of the characteristics that they have chosen to differentiate in make them unable to do what Bitcoin does. Bitcoin has been doing it longer, so there is network-effect as well. In the short term, they do compete indirectly for the attention of developers and speculative investors; as a technology, they do not compete any more than a lion competes with a shark. It is about choosing platforms that fit a particular niche or purpose. Are you doing complex smart contracts that require flexibility? Ethereum. Do you want robust store-of-value without consensus failures? Bitcoin. Zcash is making trade-offs for privacy and anonymity. Conservatism vs. an attitude of 'move fast, break things.' You don't reconcile them, you choose the thing that fits the niche and is adapted to that particular environment. (3:49) Are Ethereum, Zcash, and other altcoins competing with Bitcoin because of the blocksize and scaling debate? Will Bitcoin apps and startups considering moving over high fees and the delay in implementing the Lightning Network? It is ridiculous that they are competing over this debate. Ethereum scales worse than Bitcoin, and Zcash scales worse than Ethereum. The fact that they haven't been hit with a major scalability issue yet is because they haven't actually scaled yet. Ethereum will do sharding? Bitcoin will do it too, and do it 10x more efficiently. The idea that you would take your application out of Bitcoin "because it isn't scaling" and move it over to Ethereum or Zcash, which have worse scalability issues, is a bad trade-off. Scaling is not easy and there are no easy answers. Money frequently drains out of bitcoin into altcoins during times of stress, but it doesn't last very long because they use the price increases to buy more bitcoin, and the entire market cap of the ecosystem grows overall. This allows us to test the limits of all the cryptocurrencies; they will all have governance problems that they will have to mature through to survive. The reason you're still dry is you haven't left the harbor yet.
