Net Zero
World first system measuring, recording and reporting blockchain-authenticated
by food portion, reporting of carbon footprint and other sustainability measures such as
biodiversity, water quality, soil quality, animal welfare, etc.

The ARCZero Experience

Starting as a European Innovation Partnership (EIP) ARCZero made up of a co-operative of seven commercial farms in Northern Ireland

Define Net Zero for a farm as:
Gross annual GHG emissions less Gross Annual Carbon Sequestration, adjusted for Renewables and Waste Management
More than half of Earth's species living in the soil (Natural Academy of Science, Aug 23); the ARCZero project showed via scientific testing the role of different land uses in building soil organic carbon (R. Baffara, WUR, 2023)

The Complete Solution

Two Hands in collaboration with two US tech leaders have created a system for measuring, recording and reporting blockchain authenticated, by food portion, from source to plate, reporting of carbon footprint and other sustainability measures, such as biodiversity, water quality, soil quality, animal welfare etc.  

  1. Lobsters are caught, tagged and sealed in ‘pots’ on the ship. 
  2. The lobsters are then transported to the port in sealed containers.
  3. The lobsters are then transported to the processor facility.
  4. The lobsters are weighed and put into a tank with local seawater to purge. This prepares the lobsters for transit, reducing stress and mortality. The purging takes place for 36 - 48 hours in Australian sea water.
  5. The lobsters are weighed, packed into a box and transported to the airport in a temperature-controlled container.
  6. The freight forwarder ensures that the lobsters are available for any customs inspections.
  7. The lobsters are then transported by air to China in a cold storage container.
  8. The logistics team accompanies the lobsters after clearing Chinese customs and the duty, tariffs and VAT are paid.
  9. The lobsters are then transported directly from the airport to the restaurant.
  10. The restaurant receives the lobsters and stores them in a controlled environment.
  11. The lobster is prepared and served to the diner.

Fighting Food Fraud

Existing supply chains are opaque, middlemen pocket up to 60% of earnings. 

Two Hands has re-engineered the supply chain from the ground up to put people at the centre. Transparency is key. What you do on Two Hands today, will affect who wants to do business with you tomorrow. Trust is confident vulnerability. Two Hands fosters trust by enabling everyone to see, who does what they say they will.

When buying from a local fish market it is impossible to know:

How many wholesale facilities did it pass through?
What temperature was the lobster stored at each facility?
What was the quality of the water in each facility?
How many times has the animal been handled?
Where was it caught?
Was the animal miss treated?
How long ago was the animal caught?

“Food fraud represents a USD 40 billion problem worldwide and is allegedly worth
more  than the heroin trade and firearms trafficking combined”
- Dr Sylvain Charlebois, Professor in Food Distribution and Policy, Dalhousie University, Canada


Why Use Blockchain?

Instead of “trust, but verify”, blockchain enables us to “verify, then trust”. A centralised system is susceptible to abuse. If a business can pay to remove content that is bad for business, how can the system be trusted? How can they be transparent when their supply chain operate in data silos? In a decentralised system there is no one to pay. Everyone can see if your deliveries are late, or you don’t pay your bills on time or you sell low quality product.

In the Two Hands model, a last mile distributor operating a node in China has access to every transaction. The distributor can assure their customers of the data integrity with confidence. The distributor has a record of every transaction in their supply chain. 

Immutable changes to a tag's data are visible to everyone in the network. The transactions are immutable and require consensus to be added into the ledger. The shared data view makes the supply chain more transparent.  Transparency acts as a trust anchor for collaboration between people across continents. 

“It means that we will be able to get our product into China in the most pristine condition ever and the Chinese people will be able to experience perfect Southern Rock Lobster, just as they are when we take them out of the water.”
