Blockchain

The term ‘blockchain’ refers to an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way. It’s well-known for being the technology at the heart of bitcoin and other virtual currencies.

 If you’re completely new to blockchain, then we would recommend these three steps to get started:

  1. Read these 14 tweets to understand the key components and factors.

  2. Watch this five minute video.

  3. Create a blockchain yourself with this quick demo.

A blockchain is a long chain of data entries. No rocket science involved here. The catch over here is that not one person or organization for that matter is in charge of the blockchain. Each record is known as a block. When a person adds a block every person who has ever added a block on the chain is informed. This makes the whole process extremely transparent and there are no intermediaries involved.

Breaking it down to its simplest form, it’s a long chain of blocks, with each block representing a data entry. Some think of it like a Google spreadsheet, where you can see every entry and change made to the file.

Blockchain is a complex frontier technology. Unlike drones and solar panels, we can’t see or touch it. But the Frontier Tech Hub has already helped FCDO advisors test blockchain solutions in humanitarian and supply change contexts, and it only takes a little learning to see the potential for it across the world of development.

Fact File- 3 myths about blockchain

Myth 1: Blockchain and Bitcoin are the same thing

🤑 Blockchain is the technology behind cryptocurrencies like bitcoin and other virtual currencies, but they are not the same thing.

Myth 2: a blockchain is 100% safe

🦺 A blockchain is a record where nothing can be hidden or tampered with (as is often the case with traditional records), and no one entity or person can “own” it. This makes it a 99.9% secure record, but not 100% incorruptible, as some might claim.

Myth 3: blockchains are always public

👻 While many blockchains are public, there are also private ones with their own applications to run within a closed network. Private blockchains are “permissioned”, while public blockchains are “permissionless”.

What functionality can drones offer?

Drones are commonly used to support development and humanitarian outcomes by collecting images, carrying cargo, providing connectivity and precision spraying.

What we have learned from testing drones and UAVs - headlines from the report.

“UAVs have great potential to enhance the impact of our work and it’s critical that Governments, donors and the private sector collaborate to build sustainable and responsible operations and support the regulatory and ethical frameworks needed to drive success”
