SSI and Verifiable Credentials are the latest development in identity management. They offer many benefits over existing federated identity management systems. Unfortunately some proponents of SSI are mandating that companies implement decentralised identifiers (DIDs) and blockchains in order to benefit from SSI. This is not necessary. In fact the W3C Verifiable Credentials Data Model Recommendation makes it clear that DIDs are not needed for verifiable credentials, and vice versa. DIDs and blockchains are something of a ball and chain around the legs of companies that want to benefit from SSI when leveraging their existing web based security infrastructures. This keynote talk will describe how it is possible to build standards compliant high performance, user friendly, SSI systems using the World Wide Web, Transport Layer Security, Jason Web Tokens, Web Authentication and X.509 public key certificates, allowing them to experience all the benefits of SSI without the ball and chain impediments of DIDs and blockchains. - the benefits of SSI over existing identity management systems - the downsides of DIDs and blockchains - the upsides of using existing World Wide Web infrastructure to build your SSI solution
