Introducing Blockchain with Lisp: Implement and Extend Blockchains with the Racket Language

Conclusion

We’ve covered a bunch of stuff in this book. As a recap, we did the following:

• Section 1: We got a general high-level overview of the blockchain system.

• Section 2.3: We learned basic Lisp using the Racket (Scheme) dialect.

• Section 2.4: We created an executable with DrRacket.

• Section 3: We created a basic implementation of a blockchain that implements the structures and the operations for wallets, blocks, transactions, and digital signatures.

• Section 4.1: We implemented support for smart contracts.

• Section 4.2: We implemented support for peer-to-peer communication.

Here are some ideas for further development:

• Usually, a list of IP addresses and ports is contained in some public servers, but to keep things simple, we ignored that and implemented ...
