But in the Matrix ecosystem, a single \"ping\" triggers a complex chain of events involving E2EE decryption, push rule evaluation, and state synchronization. This talk dives into the architectural challenges of implementing a robust, privacy-respecting, and energy-efficient notification engine in Trixnity.\n\nLicensed to the public under
