World Economic Forum (WEF) Sheila Warren, head of blockchain and data policy, addressed the Hyperledger Global Forum 2020, discussing the potential of blockchain to solve real-world problems. Warren warns that blockchain technology is not a "silver bullet" technology, and stronger policies are needed than ever to realize its advantages. We must start to reconsider the basic structure of the technology stack and the way it allows interaction with the blockchain. Warren discussed the potential benefits of blockchain technology in conjunction with policy, but she explained that the technology has not yet achieved change. First, she pointed out that digital identity is still very much needed. Second, blockchain technology lacks a code of conduct. She mentioned that the World Economic Forum is currently working on a blockchain code of conduct, which will be published on GitHub next week for comment. The guidelines will in turn provide a benchmark for the needs of building applications on the blockchain network. Finally, Warren pointed out that the return on investment of blockchain is still questionable. Warren said she is still very optimistic about the technology, and she thinks everyone should.
