Two billion years ago, the Earth's atmosphere was full of carbon dioxide. The planet's climate was unstable and its surface barren. However, steadily the atmosphere's CO2 was cycled into carbon-based life. Over time, as plants and animals lived and died, they were buried one by the other. As more and more carbon ended up in the ground, there was less and less CO2 in the atmosphere. Steadily the climate stabilized and the Earth's biosphere blossomed.

Today, our petroleum based plastic comes directly from these ancient underground carbon stores. As a form of carbon, what we do with our plastic can be of ecological benefit— or not.

When plastic is dumped, it degrades into dangerous micro-plastics. When plastic is incinerated it returns to the atmosphere as CO2. And when plastic that is processed by industry it causes factories to spin and churn, resulting in more emissions and more plastic products.

In this way securing our plastic out of these routes, has important ecological value. Especially when we concentrate and secure plastic in the same way that the Earth cared for it carbon.

This process of plastic sequestration is defined as a manual, net-zero, non-industrial process. In order to be sequestered, the resulting secured-plastic must meet the criteria of plastic sequestration to ensure that it is in fact green.

One of the most universal and accessible means of plastic sequestration is ecobricking.

Ecobricked plastic, if it has been authenticated to have met the criteria of plastic sequestration, emobodies an ecological value. This value can be quantified by the weight of the plastic sequestered within it.

Brikcoins are based on the ecological value of authenticated ecobrick sequestered plastic (AES plastic).

Step 1: Ecobricking

The brikcoin blockchain revolves around the ecobricking of used plastic. Ecobricking is an established means of securing plastic. It is a time-consuming, labor-intensive process that is most effectively done manually. If done properly an ecobrick can be used for long-term building applications; ensuring that its plastic is secured from industrial processing and release into the biosphere.

Once complete, ecobrickers log their ecobrick on the GoBrik platform. A serial number is given by the system and the ecobrickers enscribes this permanently on the ecobrick. A photo of the ecobrick with the serial number is taken and the logging completed.

The logged ecobrick is then automatically queued for review. The ecobricker is awarded credits that allow them to validate other ecobricks that have been logged.

Step 2: Validation

The GEA has defined standards for an ecobrick. Only when a packed bottle meets these standards is it considered an ecobrick, and only then is the plastic it contains considered sequestered.

Using one validation credit, ecobrickers are entitled to validate one ecobrick from the queue. The validator proceeds through a three step process of reviewing ecobrick, to ensure that it meets the criteria and standards of plastic sequestration. In total, each ecobrick is reviewed by three validators in the community.

Step 3: Authentication

An algorithm calculates a validation score based on the review. The three validation scores are averaged and if the average exceeds the minimum threshold, the ecobrick is authenticated. Brikcoins are then generated and issued to the validators and the GoBrik Central Reserve based on the weight of the ecobrick.

The amount of Brikcoins generated is a function of the weight of the authenticated ecobricked plastic. This 'plastic standard' is pegged to a ratio of 1 BRK (ß) to 100g of AES plastic. For example, a 322g ecobrick will generate 3.22 ß, while a 0.41 kg ecobrick will generate 4.10 ß.

The Brikcoin blockchain is developed and maintained by the Global Ecobrick Alliance in pursuit of its mission and vision of plastic transition. As a not-for profit Earth Enterprise, the GEA is guided by a mandate of acheiving net-green ecological impacts and redistributing excess revenue back to the global ecobrick movement.

Through a combination of enterprise structure and server infrastructure, we aim to minimize our grey ecological impacts and maximize of our collective green impact.

The Brikcoin blockchain is permissionless, meaning that its ledger is centralized on GEA managed databases. This structure was elected to minimize the impact of the servers supporting the blockchain, while at the same time maximize the blockchain's empowerment of the decentralized global ecobrick movement.

On Earthday 2020, the GEA released version 1.0 of the Ecobricks & Brikcoin Whitepaper, on The Commodiciation of Manually Sequestered Plastic. The 32 page document is the work of half a dozen contributors specializing in fields ranging from micro-plastic research, alternative currencies, philosophy, community development and database development.

The white paper lays out the framework for basing a currency on the ecological value of plastic sequestration.

The white paper is updated as of March 2022 to reflect three years of beta-usage by our 50,000 gobrik users, over 150,000 ecobricks and a pool of over 250,000 ß (as of March, 2022).
