    What Is Libra? Breaking Down Facebook’s New Digital Currency










    Facebook
    has been in the news quite often over the past few years — and usually
    for all the wrong reasons. The social media giant has been lambasted
    over its privacy practices, its seemingly anti-consumer stance and even
    an apparent investor revolt in which shareholders voted (albeit
    symbolically) to remove Mark Zuckerberg from the board of directors.



     


    However, the company’s most recent announcement that it is launching a digital currency
    appears to be finally turning the tide for Facebook. The new coin,
    dubbed Libra, is a stablecoin of sorts, though it functions much
    differently than currencies like tether. Additionally, Facebook has
    built a blockchain to support Libra.


    Facebook
    intends for the new cryptocurrency to be a replacement for paper money
    and even credit cards, in many cases. The goal is to create a more
    efficient payment system that holders can use immediately and directly
    from their apps. This includes transferring money to friends or family
    (much like Venmo, but without many of the restrictions), paying
    merchants for services, and acting as a replacement for cash in
    underbanked areas.


    One of the company’s biggest stated goals
    is for Libra to function as currency for migrant workers, unbanked
    populations in the developing world and more. By creating a simple
    system that offers similar fungibility to cash, Libra can help people
    keep their funds safe and accessible, even without banks.



    While
    it definitely seems promising, there are questions about exactly how
    Libra will operate, as well as who will oversee its management. However,
    industry insiders and observers have hailed this as a positive
    development for a niche sector desperately in need of mainstream appeal.


    What is Libra?



    In many ways, Libra is similar to other cryptocurrencies and especially stablecoins.
    It is built on a native blockchain and backed by a reserve of several
    currencies meant to mitigate the impact of price volatility. On the
    other hand, the new digital currency
    is different enough from other coins to warrant a closer look,
    especially now that the team has released its testnet and accompanying
    white paper.


    According to the project’s leadership, the
    idea for Libra is to operate more as digital cash than the traditional
    speculative function most cryptocurrencies serve. To this end, Libra is
    designed to be easier to transact with and to offer faster throughput
    along with quicker validation times. Despite the similarity to
    fiat-pegged stablecoins, Libra is an alternative that is fundamentally
    and technically different — too different, some believe.


    Libra strays from the beaten path



    First,
    Libra is a blockchain without the blocks, or the chains. While the
    Libra blockchain is technically structured like many others, it
    functions quite differently, relying on validators with permissioned
    access rather than nodes on the chain. The white paper itself states,
    “There is no concept of a block of transactions in the ledger history,” with data assigned to validators sequentially (by number) instead of in groups.


    In
    short, instead of operating like a traditional distributed ledger (in
    clusters of data), the Libra blockchain uses a single data structure
    that records all transactions and states over time. It is also worth
    noting that currently, the validator network is made up of 27 companies —
    including major names like Visa, MasterCard, PayPal, eBay, Uber and
    Vodafone — which have each pledged $10 million for Libra’s development,
    and the foundation plans to have up to 100 validators in total.


    Libra is based on a new programming language called Move, which will eventually be used for smart contracts,
    and therefore full applications on the Libra “blockchain.” This is a
    more complex procedure than the standard forking method most blockchains
    utilize, as it requires a ground-up approach. However, due to Libra’s
    goals and technical complexity, working on a proprietary framework makes
    future development easier.


    Due to these unique twists in the
    traditional blockchain architecture, some experts argue that Libra isn’t
    quite a blockchain. According to SilaMoney Chief Technology Officer
    Alexander Lipton, for instance:



    “Libra is NOT a
    blockchain in the traditional sense, since it is lacking most, if not
    all necessary attributes; it has to be open, public, censorship
    resistant, immutable, neutral, etc. which Libra is not, based on the
    whitepaper.”


    To make use of the storage and
    bandwidth, expect to pay Facebook — or the Libra Association — a fixed
    fee. The fee, along with the basket of assets being held in the Libra
    Reserve, is expected to be enough to cover Libra’s operational expenses,
    as well as to pay out dividends to holders. While some have argued that
    this model is unfeasible, others believe that even just the interest on
    the reserve funds could be enough to keep investors receiving dividends
    and cover operational overhead.

    Others have noted that no matter
    how its structured, Libra will still earn dividends. According to Alex
    Frenkel, VP of product management at the Kin Ecosystem:



    “The
    white paper seems to indicate that Facebook won't get a cut through
    transactions, but that doesn't mean that they don't stand to
    substantially profit. Their focus on international remittances and
    similarities to modern banking structures show that the Libra
    Association could earn big dividends on the interest."


    Moreover,
    Libra promises some intriguing technical specifications. The blockchain
    will use a byzantine fault tolerance (BFT) consensus method, which
    helps expedite transactions due to lower verification thresholds and
    faster validation times. It also makes it much more resistant to
    bad-faith actors. 

    Additionally, the permissioned and
    limited-access nature of the network reduces the overall load of
    managing nodes. Though the resulting product will be fast — at an
    estimated 1,000 transactions per second — the compromises made to get
    there are enough for the biggest blockchain advocates to cry foul. Industry guru Andreas Antonopolous, for example, said:




    “What
    Facebook, or any company like Facebook, is proposing is not a
    cryptocurrency. It doesn’t have any of the fundamental characteristics
    of cryptocurrency. It doesn’t stand on the five pillars of an open
    blockchain. These are open, public, neutral, censorship-resistant, and
    borderless. Facebook has left true decentralization by the wayside in
    exchange for broader industry appeal.”



    The
    issue of centralization weighs heavy on many of the new coin’s critics.
    For one, blockchain’s goal is to remove the need for central control and
    provide a more transparent transaction process. As Decred co-founder
    Jake Yocom-Piatt notes, “Libra goes against the central ideological
    underpinning of cryptocurrency — it’s not decentralized. Facebook has
    already garnered a reputation for questionable privacy practices.”


    The
    president and founder of the Saga Foundation, Ido Sadeh Man, added
    that, “If the control over the currency remains in the unelected hands
    of Facebook and its commercial partners alone, this might very well turn
    the dream into a nightmare for all of us.”


    On the other
    hand, Antoni Trenchev, co-founder and managing partner at Nexo, shared
    with Cointelegraph perhaps the most popular opinion among consumers:



    “We
    believe that Libra’s concept of minimal volatility will lower foreign
    exchange (FX) cost and facilitate even smoother cross-border trading
    capabilities and social inclusion. Libra will bring broad financial
    institutional support and will encourage mass adoption of
    cryptocurrencies in a variety of activities, notably in e-commerce,
    investments, social media interactions, the shared economy and beyond.”



    Crypto shows cautious optimism



    Although
    new entrants to the market are usually seen as rivals, Libra’s testnet
    and launch announcement have been met with general enthusiasm from the
    broader crypto community. Despite the added pressure from a new major
    player in the sector, the announcement is seen as an important step
    toward mainstream acceptance of crypto. Tron founder and CEO Justin Sun told Cointelegraph:



    "I'm
    excited to see Facebook entering the blockchain space with its Project
    Libra cryptocurrency. Just like JP Morgan and IBM, some of the biggest
    companies in the world are starting to recognize the promise of
    cryptocurrency and see its potential for changing the way consumers and
    businesses interact globally.”



    Even so, these optimistic statements come with some reservations. Facebook’s track record on privacy is still a concern to some observers, and even the United States Senate Banking Committee has set
    a hearing to discuss Libra’s potential impact as well as regulatory
    concerns. Echoing these concerns in some regard, Sun also acknowledged
    that “there are of course many questions outstanding: regulation,
    interoperability, and openness, to name just a few.”

    Wanchain Foundation CEO and founder Jack Lu told Cointelegraph:



    “This
    is a truly important and monumental step for the blockchain and the
    cryptocurrency industry. Gradually, Facebook’s coin will likely become
    increasingly regulated, else governments will likely begin censoring
    network participants (who are accredited investors and multinational
    corporations).”



    One of the biggest
    advantages Facebook will have once it fully launches Libra is its
    massive user base. Its ability to market to a captive audience could
    help boost adoption numbers. In comments to Cointelegraph, Binance founder and CEO Changpeng Zhao noted:



    “Facebook
    probably has a hundred times more users than the cryptocurrency
    industry combined today. The Facebook project will educate a lot of
    people about cryptocurrency. Regardless of the criticisms targeted at
    the company, I believe this is good for the industry in the long run.”



    Let’s wait and see



    For
    now, Libra’s testnet is the first real glimpse the industry has had
    into the new digital currency. Some are already comparing Libra to other
    cryptocurrencies and remain skeptical. To many, Libra’s centralized
    nature and the lack of transparency Facebook is generally known for make
    it a dangerous tool. They see increasing regulation, especially as the
    assets sustaining Libra’s price are controlled by a centralized legal
    entity, making it easier to co-opt the system. 


    Others
    see this difference as a positive. Xavier Rashotsky, the director of
    special projects at blockchain firm Salt, notes that “we can be certain
    that Libra will have a reasonably different profile than the
    inflationary and economically volatile underpinnings of a USD-backed
    stablecoin. Libra will compete with popularized stablecoins as a new,
    innovative, and substitutable product deployed on proven and adopted
    forums.”

    Regardless, the creation of Facebook’s Libra remains a
    potentially momentous occasion for the crypto community. The new coin
    already has support from many corners in the sector and could be a major
    step in the right direction for an industry looking for mainstream
    legitimacy. While it is unlikely to fulfill the goal of a truly
    decentralized currency, Libra could be a milestone into crypto becoming a
    broadly accepted technology.
