Is There a Future for Ethereum?
In just over a decade of existence, Ethereum (CRYPTO: ETH) has pioneered smart contracts and managed an ambitious transition from a proof-of-work to proof-of-stake validation system. Proof-of-stake cryptocurrencies are more efficient and use a fraction of the energy of proof-of-work. And smart contracts are tiny pieces of code that make blockchains programmable.
Being first to market and committed to constant development has given Ethereum a solid lead in the programmable crypto world.
