Here's what Facebook's new cryptocurrency Libra will look like and how it will work

It's official, Facebook's making its own currency.

The social network on Tuesday unveiled Libra , the secretive cryptocurrency it's been working on for more than a year. The currency is being backed by investment from big payment companies like Mastercard, Visa, and PayPal, as well as tech giants including Uber and Spotify.

Facebook has high hopes for Libra, placing the focus squarely on providing cheap, accessible financial services to the 1.7 billion people around the world without bank accounts.

It's set up a subsidiary company called Calibra, a wallet to handle users' cryptocurrency dealings, plus an independent not-for-profit "Libra Association," made up of founding companies that have already thrown their weight behind Libra to the tune of $10 million each.

Here's what we know about what Libra will look like, how it's going to work, and how people will be able to get involved.

1. Libra will be accessible through Facebook Messenger, WhatsApp, and a standalone app

Facebook has said a Libra digital wallet, in which people can store the cryptocurrency, will be accessible through Messenger, WhatsApp, and an app called Calibra which Facebook says will be downloadable through the Apple App Store and the Google Play store.

A picture from a Facebook press release gives us some idea of what this will look like, although the company says there's a way to go before it becomes a fully functioning consumer service.

2. Youll need a government-issued ID to set it up

Once Libra launches in 2020, people will need to provide a government-issued ID to set up an account.

TechCrunch's Josh Constine writes that users will need to provide additional verification details, but if Facebook wants to keep Libra accessible to the 1.7 billion people in the world with no bank account, it will want to keep the amount of documentation required to set up an account to a minimum.

Calibra is already signing people up for "early access."

3. How will users put money in their Calibra wallets?

Users will be able to convert their local currency into Libra and then store that balance of Libra in their Calibra wallet. They'll be able to do this electronically, converting currency into Libra either using the Calibra app itself or third-party wallet apps.

In terms of converting real-world cash, they'll also be able to head brick-and-mortar shops like grocers or convenience stores to top up their balance, much like people can now with top-up phone pay-as-you-go phone plans.

The idea is that a Libra will be roughly the same value as a dollar, euro, or pound so it will be easy for people to get their heads around. A valuation is still yet to be determined, however.

4. What will you be able to pay for with Libra?

So far, Facebook has shown off Libra for money transfer. Here's an example from the Calibra website:

However, Libra won't just be for individual money transfers. The Calibra website says the first version of the app will "support peer-to-peer payments and a few other ways to pay such as QR codes which small merchants can use to accept payments in Libra."

"Over time there will be many others including in-store payments, integrations into point-of-sale systems, and more." Point-of-sale systems typically just means a till, or a card reader.

Facebook's VP of blockchain product Kevin Weil also told Business Insider's Rob Price that down the road, Libra could be integrated into the systems of Calibra's partners such as Uber.

5. It wont be fully controlled by Facebook

Facebook has set up an independent "Libra Association" to govern the currency. Facebook/Calibra is one of the 28 "founding members," alongside heavy-hitters including MasterCard, Uber, and Andreessen Horowitz. These firms paid a minimum of $10 million to join.

Mark Zuckerberg wrote in a blog post following the announcement of Libra that he hopes to get 100 members onboard before the currency launches, and it is theoretically open to rivals like Google and Twitter.

Being a member of the association entitles you to one vote, which could be used to select new founding members and elect a Libra Association managing director who will appoint an executive team.

6. Calibra wont share any info with Facebook unless you really want it to

"Any information you share with Calibra will be kept separate from information you share on Facebook," Zuckerberg wrote in his blog post.

Libra's default setting will be to not share any information with Facebook, and the company is insistent that financial data won't be used to target ads at users. The Calibra website also says that users won't need a Facebook or WhatsApp account to sign up to Calibra.

However, TechCrunch's Constine said that Calibra may ask if users wish to import contacts or profile information from Facebook.

7. So whats in it for Facebook?

In simple terms, more ad revenue. Facebook's hope is that businesses on its platform will adopt Libra, selling goods to customers using the currency. If this helps grow sales, the thinking is that it will encourage these companies to place more ads on Facebook.

8. Developers will be able to build stuff using Libra blockchain tech

Facebook is open-sourcing the new coding language it used to build Libra, called Move. This means developers will be able to create new apps using Libra.

In its blog post announcing Calibra, Facebook was careful to hedge its bets with a disclaimer:

"This announcement contains forward-looking statements regarding our future product and business plans and expectations. These forward-looking statements may differ materially from actual results due to a variety of factors and uncertainties, many of which are beyond our control."

Basically Libra is an unfinished product, so anything could change before it materializes in 2020.
