Ethereum is a decentralized blockchain platform that was created by Vitalik Buterin and Gavin Wood in 2015. It uses a cryptocurrency called Ether as its native token to power transactions and operations on the Ethereum network. Ethereum’s proponents envision a future where the network forms the foundation for a second platform layer, called L2, where decentralized applications are run.

As we approach the 10th anniversary of Ethereum’s creation we wanted to understand the state of the technology so we spoke with Andrew Koller who is an engineer at Kraken, which is a software company and popular cryptocurrency exchange. In this conversation Andrew talks about Kraken, security considerations at an exchange, the history of Ethereum, L2, and the future of Ethereum.
