SSI on Blockchain: the failed start in Germany
summary
Germany builds multiple pilot systems that all fail: a vaccination registry that writes database hashes into five blockchains while verifiers query a single mutable DB, a mobile driver license app whose unsigned QR payload lets attackers redirect data, and a consortium PKI stored on a permissioned Ethereum network with an exposed gas endpoint and a 0mq limit of 500 connections that enables denial and remote code execution. Each project ships quickly, collapses under load or exploits, and requires replacing blockchain with qualified signatures or hardened legacy services.
