Bitcoin technology, built on the Bitcoin blockchain, allows users to send bitcoin (BTC) balances. The Bitcoin blockchain maintains each user’s BTC balance, making Bitcoin an excellent non-sovereign store-of-value with unique monetary properties.
Ethereum takes blockchain technology further. On the Ethereum blockchain, all value is programmable as “smart contracts” implement if/then logic into money itself. Since 2015, the Ethereum blockchain has grown into the most actively used blockchain in the world. Ether (ETH), the cryptocurrency which powers the Ethereum blockchain, is now the second-largest cryptocurrency by market capitalization at $130 billion.
