Grassroots Flash Uses a DAG Payment System for Local Cryptocurrencies

Summary

The document presents Grassroots Flash, a payment system intended for grassroots cryptocurrencies that support locally formed digital economies. The proposed system uses a blocklace, described as a directed acyclic graph counterpart to a blockchain, to enable payments among participants. Its broader motivation is to let local economies emerge without initial capital or external credit, exchange with one another, and potentially connect over time.

The paper analyzes the system's safety, liveness, privacy, and efficiency, and states that it proves the design is grassroots. It also frames mutual trust as a source of liquidity and suggests these currencies could help extend access to financial services. The supplied description does not provide the protocol mechanics, formal assumptions, benchmarks, or details of the security proofs, so it is not possible to assess implementation costs or practical performance from this summary alone. Its relevance to trading is mainly through cryptocurrency payment infrastructure rather than a trading strategy.

Key ideas

• Grassroots Flash is a payment system designed for local digital currencies.
• The system uses a blocklace, a directed acyclic graph structure related to blockchain.
• The paper examines safety, liveness, privacy, and efficiency.
• The proposal aims to support economic exchange without requiring initial capital or external credit.
• The brief description does not provide implementation details or quantitative performance results.

# Grassroots Flash: A Payment System for Grassroots Cryptocurrencies









The goal of grassroots cryptocurrencies is to provide a foundation with which local digital economies can emerge independently of each other and of global digital platforms and global cryptocurrencies; can form and grow without initial capital or external credit; can trade with each other; and can gradually merge into a global digital economy. Grassroots cryptocurrencies turn mutual trust into liquidity and thus could be a powerful means for 'banking the unbanked'. Grassroots cryptocurrencies have not been provided yet with a payment system, which is the goal of this paper. Here, we present Grassroots Flash, a payment system for grassroots cryptocurrencies that employs the blocklace -- a DAG-like counterpart of the blockchain data structure. We analyze its security (safety, liveness, and privacy) and efficiency, prove that it is indeed grassroots.
