What is the best article / book to convert people from the "Bitcoin is Bad, Blockchain is good" phase?

I've been trying to write some of those articles! I'll let you be the judge on that.

I like Saifedean Ammous's "The Bitcoin Standard", which explains everything very well.

Are there many people adopting your bip 176 into wallets or the bitcoin ecosystem in general since it got merged in dec. 2017? I like the idea especially since lightning network is up and running with similar amounts.

I would love for BIP176 to get more adoption. It's an informational BIP so, nobody is obligated to follow, it's just something wallets can do if they choose to do so. I personally think it's a lot easier to think in terms of bits, but opinions differ.

Lightning transactions definitely change things from a micro-payment perspective. We'll have to watch the space closely to see if that becomes enough of a use case that new vocabulary becomes standard there.

Jimmy what you think about "Private Blockchain". Projects like Hyperledger, Exonum and so on. A lot of crypto/blockchain enthusiast are very sceptical about this and it's really interesting what you think about it. I can definitely see the scenarios where this kind of Frameworks and Libraries will be suitable.

  • Supply chain
  • Public sector
  • Business network
  • Health records management and so on.

Thanks in advance.

What's the fairest criticism of bitcoin as a technology right now?

Probably a lot of the bugs in the core code that are very annoying. Endianness choices, OP_CHECKMULTISIG, 4-byte timestamp. The original code wasn't that good.

I'm talking something like Segwit2x.

Hardware breakthrough would be like a 2nm chip fab that can produce ASICs 100x more efficient than current generation ones for much cheaper.
