I find Ethereum’s combination of currency and law to be incredibly exciting. Then again that could definitely be considered a downside. In the grander scheme of things it might be better for money to be considered mundane. But that might only be a function of time.
Back to the excitement, though:
Decentralization, scalability and security are among the important properties that blockchain systems should have, but there are conflicts. Off-chain solutions are useful, but limited. According to Buterin, it’s very easy to have two of these properties but very hard to have all three. However, Ethereum’s ambitious goal should be that of achieving all three at the same time. “We want to scale to thousands of transactions per second, on chain, without any supernodes,” reads one of Buterin’s slides.
Ambitious is right.
