holochain-mutual-credit v0.0.9

Holochain generic mutual-credit

Generic mutual-credit implementation in Holochain.

This zome is a generic implementation of a mutual credit system. It's just a piece of the puzzle, and maybe best used with some other zome that implements better membranes.

This is a work in progress, not production ready. Contact us if you want to collaborate!

Design: https://hackmd.io/X9KFfDJZRS2vL9uLOq1oAg?both

Todo list:

• Refactor code to use transactions as private entries and their headers to validate attestations by agents
• Refactor to prevent "double-spending" (rolling your chain back and doing a new transaction) attack vectors
• Create a reusable UI module
• Security audit to protect
• Generalize to include parameters such as: negative and positive credit limit, transaction size limit, etc.
• Publish to npm and crates.io?
