I submitted my talk application to @EFDevcon for "Fast Ethereum" on August 6th. This is almost three months ago, a lifetime in this new world. Opus 5.5 was released on September 22nd! Since Aug. 6th, here is what Ethereum obtained: - A formally verified next-generation consensus mechanism, unlocking fast finality and faster slots. - Massive improvements to post-quantum secure cryptography, lowering latency and cost. We've also heard of new threats, and old threats accelerated. Overall the highs are higher, and the lows are lower. Fast Ethereum remains centred on delivering a seamless, responsive, and asset-friendly network. But it has acquired a new dimension for me over the last three months. This is about meeting the moment with urgency and ambition, which I explore in the second part of the talk. Increasingly, we have the means of delivering a secure and more useful Ethereum, with renewed conviction. We can do this! Find my slides:
