  https://en.wikipedia.org/wiki/Extraordinary_Popular_Delusions_and_the_Madness_of_Crowds https://en.wikipedia.org/wiki/Extraordinary_Popular_Delusion... is probably useful.

    I think the old adage of "If you don't have anything nice to say, don't say anything at all" applies here. Stay out of it if you don't have anything valuable to contribute.

      "Don't say anything at all" means implicitly encouraging the massive fraud, incompetence, and eventual losses that are the defining characteristics of the blockchain space.

        Cryptocurrencies and blockchains are not the same things.

  I saved this link previously. I haven't been through it yet but looks promising. https://medium.freecodecamp.org/the-authoritative-guide-to-blockchain-development-855ab65b58bc https://medium.freecodecamp.org/the-authoritative-guide-to-b...

  If you're really wondering what a blockchain actually is, this video is a really good intro: https://www.youtube.com/watch?v=_160oMzblY8 https://www.youtube.com/watch?v=_160oMzblY8 If you want something a bit more hands-on, I'm currently following this course: https://www.udemy.com/ethereum-and-solidity-the-complete-developers-guide/ https://www.udemy.com/ethereum-and-solidity-the-complete-dev... I have only made it through the first section, and it does a really good job of explaining the basics of Ethereum and what a smart contract actually is.

  I think the most useful resource you have for understanding the foundation is directly reading and understanding the original Bitcoin whitepaper: https://bitcoin.org/bitcoin.pdf https://bitcoin.org/bitcoin.pdf For some of the basics, you can take a look at Anders Brownworth's web demonstration: https://anders.com/blockchain/ https://anders.com/blockchain/ I'd also recommend looking at the source code of some of the bigger blockchains (Bitcoin Core, Geth, etc..) and look at some smaller demo blockchain implementations: - https://github.com/Jeiwan/blockchain_go/tree/master https://github.com/Jeiwan/blockchain_go/tree/master - https://github.com/kendricktan/misocoin https://github.com/kendricktan/misocoin - https://github.com/jeffbarg/Littlecoin https://github.com/jeffbarg/Littlecoin (disclaimer: I am the author of this project)

    This is really fantastic, thank you very much.

      I second this. We need good information about blockchain to help get more people involved and move it closer to mainstream. It's still sadly, very far away, and something needs to be done about this!

  Princeton put a pre-publication draft of the book for their Coursera course. https://d28rh4a8wq0iu5.cloudfront.net/bitcointech/readings/princeton_bitcoin_book.pdf https://d28rh4a8wq0iu5.cloudfront.net/bitcointech/readings/p...

  This may be too basic for you depending on your experience, but this is a really great explanation of blockchains that I think even people without a technical background could understand: https://unwttng.com/what-is-a-blockchain https://unwttng.com/what-is-a-blockchain
