Coca-Cola and the US Department of State along with two other companies said on Friday they are launching a project using blockchain's digital ledger technology to create a secure registry for workers that will help fight the use of forced labour worldwide.

The Department of State said this is the government agency's first major project on this issue using blockchain, reinforcing the technology's growing application for social causes.

Forced labour

According to the International Labour Organization, nearly 25 million people work in forced-labour conditions worldwide, with 47 percent of them in the Asia-Pacific region.

Food and beverage companies are under pressure to address the risk of forced labour in countries where they obtain sugarcane. A study released last year by KnowTheChain (KTC), a partnership founded by US-based Humanity United, showed that most food and beverage companies fall short in their efforts to solve the problem.

The study said Coca-Cola, one of 10 global companies looked at by KTC, has committed to conduct 28 country-level studies on child labour, forced labour, and land rights for its sugar supply chains by 2020.

The US beverage giant said it has been exploring multiple blockchain projects for more than a year.

Brent Wilton, the company's global head of workplace rights, said in an email to Reuters, "We are partnering with the pilot of this project to further increase transparency and efficiency of the verification process related to labour policies within our supply chain."

Blockchain

The new venture is intended to create a secure registry for workers and their contracts using blockchain's validation and digital notary capabilities, said Blockchain Trust Accelerator (BTA), a non-profit organization involved in the project.

BTA is a global platform for harnessing blockchain to deliver social impact.

The Department of State said it will provide expertise on labour protection.

"The Department of State is excited to work on this innovative blockchain-based pilot," Deputy Assistant Secretary Scott Busby said in an email to Reuters, noting that while blockchain cannot compel companies or those in authority to abide by the labour contracts, it can create a validated chain of evidence that will encourage compliance with those contracts.

The Bitfury Group, a US tech company, will build the blockchain platform for this project, while Emercoin will provide blockchain services as well, Bitfury Chief Executive Valery Vavilov and Emercoin Chief Technology Officer Oleg Khovayko said on Friday.
