Today wrapped up the Blockchain 3.0 conference in Seoul, South Korea. Although the weather outside was chilly, inside the conference hall was warm and energetic as hundreds of tech leaders from around the world gathered together to discuss the current state and the future of blockchains and cryptocurrencies. The speaker list read like a whos-who of the cutting edge technology space. All too often those who work in the blockchain space get caught up in their own projects or are focusing on the next big ICO, but this conference reminded everyone that blockchains, like all technologies, exist in a greater context. From wine to democracy, from open source security to inclusive development, Blockchain 3.0s speakers explored a wide range of blockchain-related issues, and what areas they believed could benefit from blockchain technology the most.
