If it’s not the most high-profile cryptocurrency-related event ever, Facebook’s launch of a test network for its new digital currency, called Libra coin, has been the most hyped. It is also polarizing among cryptocurrency enthusiasts. Some think it’s good for the crypto industry; others dislike the fact that a big tech company appears to be co-opting a technology that was supposed to help people avoid big tech companies. Still others say it’s not even a real cryptocurrency.
Libra’s network won’t work that way. Instead, running a “validator node” requires permission. To begin with, Facebook has signed up dozens of firms—including Mastercard, Visa, PayPal, Uber, Lyft, Vodafone, Spotify, eBay, and popular Argentine e-commerce company MercadoLibre—to participate in the network that will validate transactions. Each of these “founding members” has invested around $10 million in the project.
That obviously runs counter to the pro-decentralization ideology popular among cryptocurrency enthusiasts.
Today’s public blockchains use too much energy and process transactions too slowly to elicit mainstream demand. This is probably the biggest obstacle to adoption of cryptocurrencies. It’s why Facebook chose not to use proof of work, the process that Bitcoin uses to reach agreement among the blockchain network’s nodes, citing its “poor performance and high energy (and environmental) costs.”
If the high-powered roster of financial firms and technology companies beat Ethereum to the punch on proof of stake, it would be ironic: public blockchains are supposed to disrupt Big Tech, not the other way around.
On top of all that, how serious is Facebook is about achieving decentralization and becoming a “real” cryptocurrency? Perhaps the fact it has made a big song and dance about being decentralized is simply a way of offsetting the firm’s appalling record on data privacy. But will users demand that the currency be more decentralized—or will many simply not care?
