#Stablecoins are subject to the same barriers and constraints as pre-existing financial options (or higher barriers in some cases, e.g. need for internet and smartphones). They can also introduce important risks on economic and technical levels.
One must closely consider the specific barriers to #financialinclusion that exist in a region and how #stablecoins or other options might address them. Regional context is imperative to addressing the complex challenges with inclusion.
Second-layer solutions (eg LN) reduce transaction validation costs but at the expense of technical resilience (certain nodes need to remain online), locked-up capital, and decentralization. Certain trade-offs are unavoidable. See p. 20 of @RaphAuerbis.org/publ/work765.p…
Permissioned blockchains similarly greatly improve scalability and transaction costs, but at the expense of requiring greater trust and technical resilience among a much smaller set of nodes (again, the solution becomes higher centralization).
