Blockchain, A Practical Guide to Developing Business, Law, and Technology Solutions, Bambara J.J., Allen P.R., 2018.

   The book covers blockchain definition, use cases, distributed technology, and especially blockchain development, with a good deal of code snippets and best practices. It targets the Ethereum blockchain, introducing Solidity and other aspects of the Ethereum framework. Additionally, there are two chapters devoted to setup, coding, validation, and deployment of a complete and comprehensive blockchain betting application.

Comparing Blockchains.
The distinction between public, consortium, and private blockchains is important. Even for “old school” distributed ledger adopters who prefer a traditional centralized system, they still get the addition of cryptographic auditability attached. As compared to public blockchains, private blockchains have a number of advantages. The private blockchain operator can change the rules of a blockchain. If it is a blockchain among financial partners, then where errors are discovered they will be able to change transactions. Likewise, they will be able to modify balances and generally undo anything. That said, there is a trail. In some cases, this functionality is necessary, as with property registry if a mistaken transaction is issued or some nefarious type has gained access and made themselves the new owner. This is also true on a public blockchain if the government has backdoor access keys like they did in the Clinton era. On the private blockchain, transactions are less expensive, since they only need to be verified by a few nodes that can be trusted to have very high processing power. Public blockchains tend to have more expensive transaction fees, but this will change as scaling technologies emerge and bring public-blockchain costs down to create an efficient blockchain system.

Nodes can be trusted to be very well connected, and faults can quickly be fixed by manual intervention, allowing the use of consensus algorithms that offer finality after much shorter block times. Improvements in public blockchain technology, such as Ethereum’s proof-of-stake, can bring public blockchains much closer to the “instant confirmation” ideal, but private blockchains will always be faster, and the latency difference will never disappear as unfortunately the speed of light does not increase by 2x every two years like Moore’s law. If read permissions are restricted, private blockchains can provide a greater level of privacy.
