About this event

Join us at Full Node Berlin for an evening focused on DeFi and smart contracts as envisioned by Chainlink, Certus One, Stakefish, CLC Group, Secure Data Links, Chainlayer

What is DeFi? Decentralized Finance (or DeFi) is an emerging category of financial applications that are being developed on top of trustless networks.

Smart contracts promise a powerful new way of doing business. Yet in the noise of the blockchain and cryptocurrency space, the power of these self-executing contracts pre-programmed into blockchains is sometimes overlooked or altogether misunderstood, let's clarify this and what that it means for DeFi initiatives.
