  • Blockchain can be explained in five layers of difficulty

    Blockchain, the key technology behind bitcoin, is a new network that helps decentralize trade and allows for more peer-to-peer transactions. Wired challenged political scientist and blockchain researcher Bettina Warburg to explain blockchain technology to five different people: a child, a teen, a college student, a grad student, and an expert.

  • Bitcoin and Ethereum are decentralized cryptocurrencies with different functions

    Bitcoin, launched in 2009, is primarily a digital currency and store of value with a fixed supply. Ethereum, introduced in 2015, enables smart contracts and decentralized apps, offering more flexibility.

  • Proof-of-work versus proof-of-stake: what's the difference?

    The two main consensus mechanisms—the way blockchains confirm and enshrine information—are proof-of-stake and proof-of-work. An overview compares the differences between the two and the latter's ability to reduce the energy intensity of the computation process, which has emerged as one of the biggest criticisms of the crypto boom.

  • Proof-of-work is the original way cryptocurrencies added new blocks to blockchains

    It’s a competitive method requiring “miners” to solve cryptographic puzzles, often using equipment that consumes massive amounts of energy. Ethereum switched to proof-of-stake, a less energy-intensive method in which “validators” stake crypto to be randomly chosen to check transactions.

The United States is home to more than 33 million businesses, the vast majority of which are small businesses, with millions being created (and others closing shop) every year. These businesses often rely on loans, provide the goods and services that keep the economy flowing, and sometimes even grow large enough to enter public markets or provide private investment opportunities.
