Let’s Create Our Own Cryptocurrency

Today I’m sharing my favorite blog post of the week, written by a blogger with username cranklin.

After giving it a lot of thought, I decided to use Python. GIL thread concurrency is sufficient. Mining might suffer, but can be replaced with a C mining module. Most importantly, code will be easier to read for open source contributors and will be heavily unit tested. Using frozen pip dependencies, virtualenv, and vagrant or docker, we can fire this up fairly easily under any operating system.

I decided to make Cranky coin a VERY simple, but complete cryptocurrency/blockchain/wallet system. This implementation will not include smart contracts, transaction rewards, nor utilize Merkel trees. Its only purpose is to act as a decentralized ledger. It is rudimentary, but I will eventually fork a few experimental blockchains with advanced features from this one.

This currency will only be compatible with…
