Blockchain is a system of recording information in a way that makes it difficult or impossible to change, hack, or cheat the system. A blockchain is essentially a digital ledger of transactions that is duplicated and distributed across the entire network of computer systems on the blockchain.

Blockchain is a potential solution to a variety of human rights challenges, from ease of access to voting and identity-based service delivery to land rights protections and supply chain traceability. The food, garment and natural resources sectors are exploring blockchain technology to combat human rights abuses in their supply chains.


Blockchain Basic Info:


"Blockchain technology is a powerful tool for building a better world. Just like electricity and the Internet, it will soon seem to be used everywhere. However, many people in today's world do not have access to electricity and the Internet. The challenge is to focus on using blockchain to achieve humanities sustainable development goals. The question is: how to use blockchain to provide for the basic human needs of everyone, everywhere, as quickly as possible, in an environmentally sustainable way, without disadvantaging anyone. I say, let's work together and do it."

- Brian Webster, Blockchain Better World

"Whereas most technologies tend to automate workers on the periphery doing menial tasks, blockchains automate away the center. Instead of putting the taxi driver out of a job, blockchain puts Uber out of a job and lets the taxi drivers work with the customer directly."

- Vitalik Buterin, Co-Founder of Ethereum

"Beyond cryptocurrency contributions, what if blockchain technology could be used to make supply chains more efficient, transactions more transparent, and end world poverty through decentralized universal basic income as a form of unconditional cash vouchers? That would be a dream worth holding onto. Since our founding more than 100 years ago, Save the Children has reached more than 1 billion children. Perhaps the next Bitcoin billionaire can help us reach the next billion children."

- Ettore Rosetti, Senior Advisor, Save the Children

"The negative environmental impact of cryptocurrencies such as Bitcoin has been widely covered in the press in recent weeks and months, and their volatility has also been flagged as a cause for concern. Nevertheless, the UN believes that blockchain, the technology lying behind these online currencies, could be of great benefit to those fighting the climate crisis, and help bring about a more sustainable global economy."
