![]() It’s a project created by an international group of professors, and it aims to build tools that help communities understand and be more intentional about their impact on the planet. Code A: Giving the ecosystem a stake in the economyĭr Leanne Ussher is an economist who works with Code A, which is short for ‘Community Decision-making for Ecosystem Adaptation/Accountability/Action’. In other words, it helps us focus our economic lens more clearly on the deeply networked world we live in, so we can optimise our resource use with an aspiration of living in harmony with nature. This happens in two ways: first, economic activities are situated in a network view, breaking down silos around people, organisations, and locations and second, it can track multiple forms of value as they flow through exchanges, regions, and production processes. HREA allows developers to build economic and financial apps that take a zoomed-out view of the economy, allowing us to see the ecosystems within it and recognise its place within the biosphere. ![]() hREA is a software toolkit, built on Holochain and based on the Valueflows economic vocabulary, itself based on a seemingly unspectacular but quietly innovative accounting standard called Resources, Events, and Agents (REA). This article explores a nascent technology that gives us a new lens through which to look at the world, and three groups that plan to use it in an effort to create more integrated and innovative ways to provide for human needs within the current system. I don’t honestly think that bookkeeping practices are the sole cause of depleted fisheries, desertification, income disparities, polluted air and water, and increasing atmospheric CO₂ levels, but I do find it telling that there isn’t even a place in our balance sheets for the imbalances we cause.īut what if there were ways to account for, and more consciously see, environmental and social externalities? And what hidden opportunities might appear when everyone has a clearer view of the people, resources, and processes that make up the whole of our geographic, economic, political, and social activity? Every externality - every ecological or social cost shouldered by the commons - simply doesn’t have a place on the books. But as the unknown sage says, “we shape our tools thereafter our tools shape us.” As a lens through which we see the world, they both enable and push us to affect the world, sometimes violently, according to their numerical, linear logic. And it can be argued that they merely reflect the values of the cultures that created them. These seem like such tame technologies all they do is help us keep track of numbers. Banking and double-entry accounting gave Mediterranean traders new eyes with which to see commerce, allowing greater understanding of business operations and eventually helped pave the way for explosive industrial growth in the past several centuries. Small metal discs gave kingdoms the power to transcend relationships in trade and finance armies, changing the stories of entire cultures in a moment. Knotted strings and sticks pressed into wet clay helped us remember promises made and kept, birthing concepts like trade and debt. project/token/src/common/currency_token.Every so often, an unspectacular technology comes along and quietly changes the face of the planet. And also let's build a couple of such ledgers. Let's now implement it! Let's build a simple token canister that allows multiple ledgers to listen for various events happening in this token. since messages you send to ledgers are small (only contain some generic transfer data: from, to, amount, timestamp), you want to pack these messages into a single batch and send them all at once - this way you could save a lot of cycles.100+ tx/block), you don't want to send 100+ messages to each ledger if the token experiences high load (e.g.besides all of that you want to make your token as efficient as possible:.and each month there is at least one more ledger appears with some new specific requirements.a bunch of personal ledgers, which keep track of transactions of a particular person or organization. ![]() ![]()
