Now, this power is in the hands of Facebook. On Tuesday morning local time, Facebook announced an ambitious new cryptocurrency project called Libra, managed by a consortium of technology and financial companies including Facebook and traditional banking companies such as Visa and Mastercard. This project is basically Facebook's view of the global financial blockchain. On a technical level, Libra is similar to Bitcoin and Ethereum: it has the same anonymous attributes and the same support for smart contracts and standalone applications. In theory, everything in cryptocurrency is good.

However, Libra is still basically a Facebook project. Facebook employees designed the blockchain and recruited partners to manage the blockchain. Libra wallets will be embedded in Facebook apps like Messenger and WhatsApp, which means that Facebook products will be the primary way people experience it. Using Libra means trusting Facebook, but the company is facing the biggest crisis of trust since its inception this year. While cryptocurrencies initially meant decentralization, Libra meant further consolidation of one of the world's most powerful companies. At its most basic level, using Libra means trusting Facebook. If the project is successful, it could mean the end of the era of cryptocurrency decentralization.
