In this chapter, we continue forward from the last chapter and begin the construction of the Helium blockchain. Firstly, we will create the interface for the cryptographic functions that are used by Helium, and next we will develop some of Helium’s blockchain functionality.

If you are primarily interested in the theory of blockchains and cryptocurrencies, please feel free to proceed to the next theory chapter.

Python Crypto Packages

Helium makes extensive use of cryptographic functions, especially SHA-256, RIPEMD-160, and digital signatures. This functionality ...
