# ChainCash: A Practical Approach to Elastic Money Creation with Trust and Blockchain Assets


## Introduction

[ChainCash](https://github.com/ChainCashLabs) is a decentralized monetary system that enables flexible money creation by combining trust and blockchain-backed assets. It operates on the Ergo blockchain, allowing users to create and manage digital currency securely, adaptably, and transparently.

This article explains ChainCash's functionality, explores practical applications, and provides links to technical documentation for deeper insights.

## Motivation and Evolution of Money

### The Need for Elastic Money

The current cryptocurrency landscape faces significant challenges, particularly with the inelastic supply of blockchain assets like Bitcoin and other cryptocurrencies. This inelasticity creates volatility and limits the practical use of cryptocurrencies in the real economy. The supply of these assets is often disconnected from economic activity, which hinders their potential as a reliable medium of exchange.

Algorithmic stablecoins attempt to address this issue by using over-collateralization, but their supply is still tied to the underlying cryptocurrency, which limits their scalability for real-world economic needs. On the other hand, centralized stablecoins reintroduce the problem of centralization, which goes against the decentralized principles of blockchain technology.

### Evolution of Money

Historically, money has evolved from primitive forms, such as barter and commodity money, to more advanced systems like metal coins, paper money, and eventually, fiat currencies. Initially, paper money was backed by tangible assets like gold, but over time, this backing was removed, leading to the rise of fiat money, which is only backed by the trust in the issuing government.

Cryptocurrencies represent the latest step in this evolution, often considered a form of "digital gold." However, their adoption as a medium of exchange has been limited by their price volatility and fixed supply. ChainCash seeks to continue this evolution by creating a digital form of paper money (IOU notes) backed by blockchain assets, allowing for an elastic money supply that can adapt to economic needs.

### ChainCash's Role in the Evolution

ChainCash aims to bridge the gap between digital commodities, like cryptocurrencies, and the need for an elastic money supply. By enabling the issuance of digital IOU notes in a peer-to-peer environment, ChainCash replicates early paper money systems but with the added benefits of blockchain transparency and smart contract guarantees.

In the 21st century, digital peer-to-peer networks allow anyone to join and leave the ChainCash network at any time. Participants can hold reserves in various digital tokens and issue notes with or without backing. The system allows for notes to be accepted or rejected based on the perceived trust and collateral behind them.

ChainCash provides a modern implementation of historical free banking systems, where multiple banks issued their own notes backed by their reserves. With the transparency and security of blockchain technology, ChainCash enables a decentralized, trust-based monetary system that adapts to the needs of its users.

**3. What happens if an agent defaults?**

- If an agent who **issued or signed** a ChainCash note defaults (i.e., they are unable to fulfill their obligation to back the note), the note can still be redeemed against the reserves of any other previous **signer**. This means that the responsibility to redeem the note falls on those who have previously backed it by signing, not on the current holder. Simply accepting and using a ChainCash note does not put your reserves at risk unless you have issued or explicitly signed the note to provide backing.
