How do zero knowledge proofs work? How do you create a zero knowledge proof transaction? Are they computationally difficult? Are privacy coins useful in authoritarian environments? Will MimbleWimble displace Zcash? What implications does the Zcash inflation vulnerability have for privacy in Bitcoin? What problem could banks or international governments pose for Bitcoin without privacy and fungibility?

These question are from the February monthly subscriber session, the sixth session of MOOC 11, and the Seoul Bitcoin meetup, which took place on February 23rd, March 7th, and April 5th 2019 respectively.

  1. You work for the banks Andreas. Every time you get a paycheck to shill small blocks, you're being paid by the crony banksters. You know that Blockstream works for the banks, and is in bed with tether/Bitfinex. You know that that BTC was taken over and destroyed as a peer-to-peer cash system. You're hurting a lot of people by doing this.

  2. I agree about privacy in the second layer as we can all run to the first layer if a bug is found. What will happen when a bug is found in a large enough currency it will remain for a long time until it collapses like all other inflated currencies. The point is people need a place to go should this happen.

  3. Cloak Coin has been around since 2014, audited in 2017, survived bear markets, unlisted from Binance (my theory: competition for their own p. coin), low supply and very undervalued.

  4. Hey Andreas. You will never know how much you have taught me. The edges on the coin are called Reeded edges. Just in case you wanted to know. Thanks for everything you do for this space. The future looks so bright. ?

  5. I am not sure I understand what the negative effects of non fungibility would be. If there is a threat from authoritarians to force an exchange or mining pool to blacklist specific coins, why should the solution be privacy? Shouldn't the solution be more decentralization? ..Make the authoritarians have to go after every single user, instead of just the exchange or mining pool.
    I am entertaining the idea that individual users can have their own blacklists (or in effect, exchange rates) of coins (or other users), which would give the ability for people to essentially extract wealth from other who they believe do not deserve it. So in effect, people cannot take the money and run. there would be no where to run, their money would just be devalues accordingly
    I don't think anonymity should be sought. It will advantage big data even moreso. They will have enough data to peel back the anonymity layer, but other regular users will have no such power. I think it is better to give more of that ability to everyone.
    Add: actually, if authoritarians attempt to get business owners, etc to blacklist coins, and the public in general doesn't agree with it, the public can just devalue the authoritarians currency, and they will no longer be authoritarians.. lol

  6. Andreas someday I would love to hear your view on privacy for smart contracts. I'm specially thinking of Enigma and their secret contracts which can be truly groundbreaking.

  7. 9:40 can someone explain this in detail please ? Does the "new coin " show in the miners address? If yes how can we tell for sure it is from the 12.5 BTC ( fresh from the oven ) as he mentioned please?

  8. Wasabi wallet has coinjoin built in for high privacy. Samourai Wallet has Stonewall and Whirlpool. Bitcoin has already gotten much more privacy tools in the recent past, not to mention the things currently being tested ?
