Title: Blockchain Development Mega Guide Post by: kasscrypto on January 30, 2020, 04:54:46 PM The blockchain learning ecosystem has changed a lot since I first started. So I thought I'd share some of the cool sh*t I've either created or found on the web.
The Mega Guide Blockchain Development Mega Guide (Medium) (https://medium.com/programmers-blockchain/blockchain-development-mega-guide-5a316e6d10df) Free courses These are about understanding more than programming but... It's a decent start. Blockchain Technology (https://www.edx.org/course/blockchain-technology) - Berkley Bitcoin and Blockchain (https://www.khanacademy.org/economics-finance-domain/core-finance/money-and-banking#bitcoin) - Khan Academy Cryptography Course (https://crypto.stanford.edu/~dabo/courses/OnlineCrypto/) - Stanford Blockchain Fundamentals (https://www.pluralsight.com/courses/blockchain-fundamentals) - Plural sight Blockchain Principles and Practices (https://www.pluralsight.com/courses/blockchain-principles-practices) - Plural sight Hyperledger Blockchain Technologies (https://www.edx.org/course/introduction-to-hyperledger-blockchain-technologie) - Linux Foundation Introduction to FinTech (https://www.edx.org/course/introduction-to-fintech) - Hong Kong University Resources How to become a blockchain developer (https://blockgeeks.com/guides/blockchain-developer/) I don't know why they chose javascript to demonstrate lol, but otherwise, this is a solid guide! https://asecuritysite.com/encryption (https://asecuritysite.com/encryption) Site is kinda ugly, but packed with information about cryptography, with demonstrations and code. https://en.bitcoin.it/wiki/Category:Developer (https://en.bitcoin.it/wiki/Category:Developer) The bitcoin wiki developer page. What the Guides don't tell you... There are a good few things these guides don't tell you. These aren't hard concepts but are often glossed over or replaced with a more convenient learning example. ...about mining In practice, mining isn't really about looking for a hash starting with serval '0' bits. Mining actually requires finding a hash that has a numerical value is less than a target hash (this results in a number of '0' bits). That target hash can be calculated from the difficulty. Bitcoin wiki page on difficulty. (https://en.bitcoin.it/wiki/Difficulty) pseudo code: Code: hash = sha256(block) ...about adjusting difficulty Difficulty must be adjusted to keep up with the changing hash rate of the network (to keep a block time of say 10 mins). The easiest way is to adjust the current target based on how much faster or longer it took to mine X blocks. pseudo code: Code: target_hash = big_endian(diff_to_target(difficulty)) I will add more to this when I get a chance Happy Coding Title: Re: Blockchain Development Mega Guide Post by: odolvlobo on January 31, 2020, 07:22:09 PM This is also a good resource:

There's more to mining than hashing: http://cryptorials.io/beyond-hashcash-proof-work-theres-mining-hashing/ Title: Re: Blockchain Development Mega Guide Post by: DaCryptoRaccoon on February 12, 2020, 05:44:54 PM Another good way to visualize what is going on in the mining process it to have a look at the mining simulator.
