Facebook's Libra shares a lot of commonalities with Ethereum ($ETH) including its problems writes Jameson Lopp in his review of the Libra white paper. Libra is a generic crypto asset protocol with one stablecoin as of now, Libra. Running essentially a proof-of-stake node system, Libra will always have issues of disconnecting from the legacy financial system. Although called a blockchain, the white paper truly describes a series of signed ledger states which still manages to be highly functional. Overall, Libra looks more like Ethereum or XRP ($XRP) than Bitcoin ($BTC).
