somechain

A complete implementation of a proof of work blockchain in python 3.7+

Simplifications

• Storage using pickledb in flat files
• Communication between peers using http api calls
• Can only send tokens to a single public key
• Serialization completely done via json
• No scripting language
• Peer discovery through a central server instead of dns seeds.
• Every node is a full node with a wallet, no light nodes (for now)
